Gain Staging
Your first adjustment for any input to your T1 ToneMatch Audio Engine is the Trim setting. The exact position of the Trim will vary depending on signal strength of your input source. The correct setting for any particular source may be different from your other sources.
Set Up Your Source
Set your source at the maximum that it will be when performing.
- Microphone
- Sing directly into the microphone using close microphone technique (lips just brushing the windscreen). Sing as loudly as you will sing during your performance. You want to set the Trim to work at your maximum volume.
- Instrument
- Turn your input as high as it is likely to go during performance.
Set Input Trim
Turn the Trim setting up until the Trim Light is solid green with occasional flickers of yellow. Use the Trim lights as your guide. (The exact position of the Trim knob is not important).
If you see flickers of red (below), turn the Trim down. You are definitely nearing or in compression. Turn the Trim down until there are no red flickers.
Bill-at-Bose [1] talks about setting the gain on a T1 ToneMatch Audio Engine.
- One difference in gain staging the T1 and the Classic is that the T1 has a three-stage trim LED. It lights up green when signal is present, yellow when you are getting pretty loud (8 to 10 dB of headroom left), and red when you dangerously close to or at full scale.
- In a way, the yellow trim on the T1 is similar to how you treat the red on the Classic. Some yellow during peaks is good on the T1, just like some red on the Classic is good.
- If the T1 trim is going red, you should back off, you are definitely nearing or in compression.
- A really helpful feature on the T1 is to go to the Prefs/Output Level menu, and see where you are relative to maximum output.
T1® Trim Pots
The T1 trim controls for CH 1-3 provide a significant gain increase when you reach the upper limit. This increase in gain is normal operation.
Most sources like typical microphones and piezo pickup systems can provide enough level without the need to add significant gain from the trim control. Certain sources like passive acoustic guitar pickups require additional gain and in these cases it can be necessary to set the trim level to the upper range of the control. When the trim control is set this high you may notice the gain change. This is normal operation. If you want to run the trim control at lower settings we recommend using a preamp or simple stomp box level booster.
The trim for CH 4/5 do not exhibit the same behavior (as the trim controls for Channels 1,2,3) as these inputs are designed for line level sources and do not have the same gain staging as CH 1-3.

Inputs
The following notes about Channels 1,2,3, 4/5 are from Hilmar-at-Bose spread out over several posts in Information on the new T1 ToneMatch audio engine
Channels 1,2,3 support
- Balanced XLR
- Unbalanced Tip-Sleeve
The Tip-Sleeve inputs are high impedance so you can plug in an acoustic guitar with passive piezo pickup or any other passive instrument directly without a pre-amp. Input impedance on Channels 1,2,3 is about 1 MOhm. Channels 4 and 5 have an input impedance of about 10 kOhm.
- Choosing the "best" input impedance is a little bit of a trade off and matching the pickup's impedance is not necessarily the best choice.
- Piezo pickups are also somewhat of a capacitor and together with the input impedance of the preamp, this forms a low pass filter.
- If the impedance is too low, then the low pass filter is in the audible range and the guitar looses sparkle and gets a little dull.
- If the impedance is too high, the system gets noisy and somewhat sensitive and finicky. For example, stepping on or simply moving a cable changes it's capacitance which creates clearly audible artifacts with a very high input impedance.
- We feel, that 1 MOhm is a very good compromise for a life application.
Bill-at-Bose gives us the following insights into Channels 1,2,3 and 4/5
- For inputs 1-3, you can physically plug a TS or TRS 1/4" plug into the jack, and get perfect fidelity.
- If you have a balanced line source and TRS cable, and plug into an unbalanced input (1,2,3), you may not get as much resistance to induced noise or potential ground loop hum as you will if you plug into the balanced inputs (4,5).
- Our Master and Aux outputs are actually balanced, so you will have an advantage on noise if you use a TRS, but they accept a TS also. So there we also wrote that they "accept" both TS and TRS.
T1 ToneMatch Audio Engine No Pads Required
The T1® XLR inputs on channels 1-3 were designed to accept inputs from microphones up to normal line-level inputs without needing a switch or a pad. This is in unlike the L1 Model I or L1 Classic) Power Stand where a pad is recommended for line-level inputs.
- The T1 ToneMatch® Audio Engine Channels 1, 2, 3 inputs will accept a wide range of signals. We have not encountered a normal use where someone needed a pad - even using +4dbU console outputs, which is as high as it gets.

Power Stand Input Setting
Connection to L1 Model I / L1 Classic with NO Remote
Here are details on how to connect a T1 ToneMatch Audio Engine to a L1 Classic or L1 Model I
Notes:
The recommended setting for Channel 3 or Channel 4 Level is 3 (see below).
With this setting you will not distort or clip the Model 1 no matter what you do on the T1. You can even use the Model 1 without the remote. More on this later.
For these conditions:
- T1 ToneMatch® Audio Engine going into L1® Model I/L1® Classic into Channel 3/4
- Balanced OR Unbalanced 1/4" cable
- Remote unplugged, OR, master volume on Remote at 12 o clock
- Proper gain staging required on the T1® itself
This will give you the same gain going into the L1® Model I/L1® Classic as if you were going through the ToneMatch® input on a L1 Model II.
If you are using the Remote on your L1® Model I/L1® Classic, then you will need to compensate a bit. If you are running the Remote master volume at max, then stick with 2 on Ch 3/4. When using a T1®, run the master volume of the R1 above 12 o'clock .
This is the power supply for the ToneMatch mixers (T1 ToneMatch Audio Engine and T4S/T8S ToneMatch® Mixers).
The T8S ships with a ToneMatch power supply because the T8S cannot draw power from an L1 Model 1S or L1 Model II Power Stand.
You will need the ToneMatch power supply to power your T1 or T4S mixer when running with an L1 Classic, L1 Model I, L1 Compact, S1 Pro System or non-Bose equipment. You will need a one of these if you have two ToneMatch mixers running into a single L1® Model II or L1® Model 1S. — details below the picture.
If you connect your T1 ToneMatch Audio Engine or T4S mixer to a L1 Model II or L1 Model 1S then the T1 ToneMatch® Audio Engine or T4S draws its power through the ToneMatch cable.
If you connect your ToneMatch mixer to an an L1 Classic, L1 Model I, L1 Compact or S1 Pro System or non-Bose equipment then you will need the ToneMatch power supply
If you are attaching two ToneMatch mixers to a single L1® Model II or L1 Model 1S then you will need this power supply to support the second ToneMatch mixer - the one connected to the Power Stand Analog Input.
See: Connecting Two T1®s to a Model II for details.
Connection to L1 Model I / L1 Classic with Remote
If you are using Channel 3 for the T1 ToneMatch® Audio Engine AND you want to use the PS1 Power Stand Channels 1 or 2 or 4 for other inputs, then you will want to connect the R1 Remote to the PS1 Power Stand.
Excerpt from the T1 ToneMatch Audio Engine Manual - page 20 - Note: this recommended input setting is now 3. See the note above.
With this setting you will not distort or clip the Model 1 no matter what you do on the T1. You can even use the Model 1 without the remote.
The T1 ToneMatch Audio Engine controls are a heck of a lot faster then the R1 controls. There is no perceivable lag.
Input setting recommendation now 3
MikeZ-at-Bose wrote[1] Bill-at-Bose and I have revisited this.
For these conditions:
- T1 ToneMatch® Audio Engine going into L1® Model I/L1® Classic into Channel 3/4
- Balanced OR Unbalanced 1/4" cable
- Remote unplugged, OR, master volume on Remote at 12 o clock
- Proper gain staging required on the T1® itself
I'm going to revise the original recommendation of 2 for Ch 3/4 to 3 - under the above conditions.
This will give you the same gain going into the L1® Model I/L1® Classic as if you were going through the ToneMatch® input on a L1 Model II.
If you are using the Remote on your L1® Model I/L1® Classic, then you will need to compensate a bit. If you running the Remote master volume at max, then stick with 2 on Ch 3/4. I would recommend against running the master volume below 12 o'clock when using a T1®.
Hopefully this is helpful - please ask away with any questions for clarification.

Aux Output
Overview
The output of any of the Channels 1, 2, 3, 4/5 can be sent to the Aux out. You can take the Aux out to provide a separate mix for recording or running to another L1 or separate amplification system.
Tap points where you can set the output to the Aux.[1]
- Dry: After Preamp: The completely dry (no processing) signal is routed directly from the preamp stage.
- Pre: With EQ & FX: The signal is routed from the preamp stage with applied processing.
- Post: After Fader: The signal is routed after the Channel volume control with applied processing.

No Reverb on Aux
Q: Why is there no Reverb on the Aux output of the T1 ToneMatch Audio Engine?
A: Hilmar-at-Bose writes[2]
- The T1 ToneMatch Audio Engine has lots of different effects units and normally they are unique to each channel. That means that the T1® has 4 individual dynamic processors, 4 modulators (chorus flanger, phaser, etc.) , 4 EQs, 4 delay processors, etc. The only exception is the reverb, which is shared by all channels.
- The AUX is also a per-channel control. That means if you turn up the AUX of channel, you expect to hear signals from channel 1 and only from channel 1. However, the output of the reverb processor contains the reverb portions of all 4 channels. If we add that to the Aux, you'd hear the reverb portions of all 4 channels and not only the channel that you are interested in. In most cases, this is probably not what you want.
- If you are familiar with conventional mixing consoles, you will find that the situation is quite similar. You can only route to an AUX output effects that are specific to a channel (normally these would be connected to the insert loop of this channel). The "shared" effects typically come into the board through an AUX return, which is not channel specific.
The discussion continues in the Message Board

Problem: Aux output does not sound right.
What To Do:
- Check if the Aux output is configured for the desired tap point for each input channel. Refer to “Routing input signals to the Aux output” on page 26.[1]
Note: No reverb comes from the Aux output even if the tap point is Pre or Post.
- Verify that each input assigns the desired signal level to the Aux output.
Aux Out to a S1 Pro System
The Aux Out is balanced mono and suitable to connect to the S1 Pro System Channel 1 or 2.
For best results use a 1/4 inch (6 mm) Tip-Ring-Sleeve cable. A 1/4 inch (6 mm) Tip-Sleeve cable will have up to -6dB lower signal and be more susceptible to line noise.
- Applicability
- This article applies to connecting the T1 ToneMatch Audio Engine Master Output or Aux Output to the S1 Pro System
- Power for the T1 ToneMatch Audio Engine
- If your T1 ToneMatch Audio Engine is connected to an L1 Model 1S or L1 Model II, the T1 ToneMatch Audio Engine will get power from the Power Stand. If it not, you will need a ToneMatch Power Supply to run the T1 ToneMatch Audio Engine.
- Cables
- The T1 ToneMatch Audio Engine Analog Outputs and the S1 Pro System 1/4 inch (6.3 mm) inputs are balanced. For best results use a 1/4 inch (6.35 mm) Tip-Ring-Sleeve cable for a balanced connection. You can use a 1/4 inch (6.35 mm) Tip-Sleeve cable, but you will lose up to -6 dB in signal strength and you may pick up line noise.
On the S1 Pro System, for each channel you are connecting to the T1 ToneMatch Audio Engine use these settings while you are setting up.
- Reverb OFF
- Bass at 12:00 o'clock
- Treble at 12:00 o'clock
- ToneMatch switch OFF
You can adjust the Reverb, Bass, and Treble after you get your basic sound working.
- S1 Pro+
You can also connect to the Channel 3 Aux input. For best results, use a 1/4 inch (6.3 mm) Tip-Ring-Sleeve cable.
Gain Staging
- Using a Bose device as the source
When connecting a ToneMatch Mixer[3] or an S1 Pro System Line Out to an S1 Pro System channel 1 or channel 2
Set the volume control to 10:00 o'clock with 1/4 inch (6.3 mm) Tip-Ring-Sleeve
- The signal strength from a ToneMatch Mixer[3] or an S1 Pro System Line Out is sufficient to achieve the maximum usable volume from the S1 Pro System
- Control the overall volume from the ToneMatch Mixer[3] or the first S1 Pro System. If you use an XLR cable, set the volume control to 9:00 o'clock
- Using a third-party source (not a Bose device as the source)
For each channel you are using on the S1 Pro System
- Turn the channel volume off
- Connect your sound source
- Adjust the volume of the source device output to the reference or nominal output level.
- On analog consoles this may be marked as unity or 0 dB.
- On digital consoles this may be marked as -18 dBFS[4][5]. The exact value (-18 dBFS to -20 dBFS) may vary depending your location[6].
- Refer to the manual for the source device for details.
- If the source device does not have metering or indicators, set the output as high as you can without hearing distortion or seeing red indicator lights.
- While playing/singing as loud as you will during your performance, bring up the channel volume until you see solid green on the channel indicator light. Occasional flickers of red are okay. If you see solid red or you hear distortion, turn down the volume.
Combo Inputs
- S1 Pro Channels 1 and 2 have combo inputs that accept
- XLR (balanced mono)
- Microphone or Line-Level inputs
- 1/4 inch (6.3 mm) Tip-Ring-Sleeve connection (balanced mono)
- Line-Level inputs
- 1/4 inch (6.3 mm) Tip-Sleeve connection (unbalanced mono)
- Line-Level inputs and instruments (e.g. guitars, keyboards, guitar processors, loopers)
- When using a third-party device (e.g., mixer or another line-level source) should I use the XLR or 1/4 inch inputs?
- The S1 Pro 1/4 inch Tip-Ring-Sleeve inputs are best suited for line-level balanced inputs. This is a better match for the signal level.
- The S1 Pro XLR inputs are best suited for microphones.
When the S1 Pro Channel input lights hit red or you hear distortion, the signal is clipping and you've reached the maximum usable volume. From the source, if the XLR outputs are line-level and the 1/4 inch Tip-Ring-Sleeve outputs are line-level, it won't matter which type of cable you use. They'll both get the job done, although the volume control setting will be lower with the XLR connection. That doesn't indicate more headroom. The maximum usable volume is the same either way.
Alternate Connection
You can use an XLR cable (mic cable) from a Line Level Source (e.g., L1 Pro, S1 Pro+) to S1 Pro or S1 Pro+ channels 1 or 2 (XLR inputs), but the signal may clip, overload, or be too high to control the volume. To attenuate (reduce) the signal, use a -20 dB or -30 dB Pad

Aux Out to a separate System
Aux Out to Headphones
The Aux Out is balanced mono intended to be connected to the balanced input of another device at line-level. This may also work with headphones but the volume will be very low and likely not loud enough to be heard over live stage volume.
If you connect to a stereo input, the signals for Left and Right may cancel out. This might not be an issue for headphones as the Left and Right signals are not combined.
Aux Out to In-Ear-Monitors
The Aux Out is balanced mono intended to be connected to the balanced input of another device at line-level. This may also work with headphones but the volume will be very low and likely not loud enough to be heard over live stage volume.
If you use an In-Ear-Monitor system that has built-in amplification, this may work.
If you connect to a stereo input, the signals for Left and Right may cancel out. This might not be an issue for headphones as the Left and Right signals are not combined.

¼ inch jack Output Connections
Connecting from a T1 ToneMatch Audio Engine ¼ inch jack (Master or Aux) to other members of the L1® Family is simple. This article is applicable to L1 Compact, L1 Classic, L1 Model I, L1 Model II S1 Pro System.
Overview
You can use TS (Tip-Sleeve) unbalanced cables, OR TRS (Tip-Ring-Sleeve) balanced cables. If the cable uses ¼ inch jack plugs and the ends are the same, then the cable should be fine.
OR
Classic or Model I
For full details see: T1 ToneMatch® Audio Engine / Power Stand Input Setting
¼ Inch Tip-Sleeve (unbalanced) to ¼ Inch Tip-Sleeve (unbalanced)
This should work fine.
¼ Inch Tip-Ring-Sleeve (balanced) to ¼ Inch Tip-Ring-Sleeve (balanced)
Since the ¼ inch phone connections at the Bose Classic and Model I Power Stand are unbalanced there is no particular benefit using balanced cables but there is no harm.
L1 Model II
¼ Inch Tip-Ring-Sleeve (balanced) to ¼ Inch Tip-Ring-Sleeve (balanced)
A balanced connection is preferred and will provide better noise rejection over greater distances than the unbalanced connection.
¼ Inch Tip-Ring-Sleeve (unbalanced) to ¼ Inch Tip-Sleeve (unbalanced)
This should work fine but a balanced connection (immediately above) is preferred especially if you will have cable runs in excess of 20 feet (6 meters) or if you hear line noise, hum or hiss.
L1 Compact
You can connect a T1 ToneMatch Audio Engine to L1 Compact
Here is an excerpt from page 12 of the L1® Compact Owner's Guide (pdf format)
Connect FROM T1 ToneMatch Audio Engine Master or Aux Output using ¼ inch jack connections.
Connect TO the Compact Channel 2 volume straight up (12:00 o'clock to 1:00 o'clock) for good results. You can turn it up higher, but if you see the light on the Compact solid red (flickers of red are okay) or you hear distortion, turn down the volume on the Compact.

Effects
Overview from Hilmar-at-Bose
Hilmar-at-Bose talks about the effects [5]
There is a large variety of effect processors out there with many different types, qualities, and prices and unfortunately there isn't a one-size-fits approach. Not the least factor is that a lot depends on personal taste and preference.
Our intention with the T1 ToneMatch Audio Engine was not necessarily to build the "world's best effects" but solid usable tools that the musician can deploy in a live situation as the situation requires. We've evaluated effect processors that are popular for live performance and used that to guide our own development. We've also tried to limit the complexity of the user interface, i.e. we provide only the most useful parameters for a certain effect and have pre-tuned the more esoteric ones.
This being said, the T1 ToneMatch Audio Engine has a couple of things that are different from most effects processors: The processing power devoted to this is substantial. The processing chip we use operates in 32-bit floating point and has a peak performance of about 2 billion operations per second (2 GFlops). That is a lot more than can be found in typical processors of this type.
This enables us also to run individual effects on all 4 channels. You can use different combination of compressor/limiter, chorus/flanger, delay, parametric EQ, etc. on each channel. The only thing that is shared is reverb. This is equivalent of having pretty much 4 multi-effects processors at the same time. This enables the user to fine tune and tweak the effects settings for each individual instruments without having to compromise between channels.
There is also some fairly unique processing such as KickGate™ (for drums), zEQ and ToneMatch™, that is not available from any other device I'm aware of.
Again, in the end each user will have to decide whether we have found the "sweet spot" or not, but I'm confident that these effects will work well for many users.
Hope that helps
Hilmar
Compressor
Using compressor/gate functions
The Comp/Gate function provides access to gate, compression, limiter, de-esser and kick drum presets with adjustable parameters. Note: To bypass the Comp/Gate settings, press the Type button. Press it again to activate.
1. Rotate the Type button to access the list of Comp/Gate effects and highlight your choice:
- Compressor 1: Light
- Compressor featuring a preset low-compression ratio with variable threshold and gain parameters. Works well as a general-purpose compressor for most instruments and microphones that require minimal level control.
- Compressor 2: Medium
- Compressor featuring a preset moderate compression ratio with variable threshold and gain parameters. Works well with basses, guitars, keyboards, and vocals requiring subtle level control.
- Compressor 3: Heavy
- Compressor featuring a preset high compression ratio with variable threshold and gain parameters. Works well with loud instruments – like horns and drums, as well as strong vocals that require more aggressive level control.
- Limiter
- Hard limiter featuring a preset ratio (8:1) with variable threshold and gain parameters. Works well with very loud instruments, such as drums, to prevent signal peaks from overloading the channel.
- De-Esser
- Side-chained compressor featuring a preset compression ratio with variable threshold and gain parameters. Designed to reduce sibilance on vocals.
- Noise Gate
- Noise gate with a fast preset attack time, variable threshold, and variable speed (release time). Well-suited for eliminating unwanted noise from microphones and instruments.
- KickGate 1: Regular
- Gate featuring a preset attack time, and variable threshold and tightness (release time) parameters. This is a Bose® proprietary technology designed specifically for kick drums. This robust gate provides maximum gain before feedback, making your kick drum as loud as possible through an L1™ system.
- KickGate 2: Fast
- Same as KickGate 1 – but adjusted for faster tempos. Select this setting if you are using a double bass drum pedal.
2. Press the Select button to select your choice, or press the Cancel button to exit the list with no change.
3. For Comp1-3, Limiter, De-Ess:
- Rotate the Thresh button to adjust the input threshold (trigger) level from -50dB to 0dB.
- Rotate the Gain button to adjust the gain from 0dB to 30.0dB. The gain bar above the button shows the amount of gain reduction. This display helps in setting the threshold.
For Gate:
- Rotate the Thresh button to adjust the input threshold (trigger) level from -90dB to -30dB.
- Rotate the Speed button to set the gate closing speed to any value from 0 (fastest) to 100% (slowest).
For Kick1-2:
- Rotate the Thresh button to adjust the input threshold (trigger) level from -20dB to 0dB.
Nick-at-Bose talks about where to start
- Question
- What are the recommended compression settings for the tone match?
Right now I'm using medium compression but need understanding what threshold does.
- Nick-at-Bose[6]
This is a great question. I'll start out by saying compression is a huge topic and there isn't necessary a best setting, though there can definitely be wrong settings.
Sometimes, maybe often times, the best setting is Bypassed.
"Threshold" is a setting that is entirely dependent on the source material. A more negative number will result in more compression. The closer the Threshold number is to 0 (which is the top of the scale in digital terms), the less compression there will be.
The top meter on the screen shows how much gain reduction is occurring. Roughly, each hash mark is about 2 dB of reduction. (No metering would indicate no compression, which means the signal is below the Threshold setting.)
Here's where I would start:
- Use the Light Compression setting
- Leave the Gain at 3.0 dB
- Set the Threshold so that on the louder parts of the performance, the meter at the top of the screen is hitting between the 1st and 3rd hash marks (starting at the right side of the screen). This would then mean that for the softer and mid-volume parts, there may be no compression happening at all. That's perfectly fine and probably desired.

MikeZ-at-Bose talks about the Compressor settings
MikeZ-at-Bose talks about the Compressor settings in the T1 ToneMatch Audio Engine[7]
Light is about 2:1, fast attack and release.
Medium is about 3.5:1, fast attack and release.
Heavy is about 6:1, fast attack and release.
All have 'soft knee' transitions.
Hope this is helpful. When tuning the compressors I relied much more by ear to determine the settings than by numerical values.
A couple of comments on the settings.
When doing general compression like is done in the T1, I found fairly fast attack and release times to be the most versatile. Slower times need more fine tuning and are more prone to artifacts when used heavily.
The threshold is the most important control on any compressor, in my opinion. Careful adjustment of this is super important. You need to make sure you are compressing the parts of the instrument that you want to compress (peaks, 20% of the time, 100% of the time etc.)
Can I use more than one compressor function
- Question
- Can you add more than one effect on a given channel under the "comp/gate" channel parameter on the rotary dial?
The is one compressor per channel, and it can do only one function at a time (compressor, limiter, noise gate, de-esser, kickgate). For most signal sources, this should not be a limitation as most of the applications where you would use these effects are mutually exclusive.
The other effects (Mod, Delay) and Reverb operate the same way. You can only choose one function within the family of the effect.

Connect Two T1 ToneMatch® Audio Engines to a Model II
The L1 Model II can accept two inputs.
This makes it easy for two performers to connect their own T1®s to a L1® Model II Power Stand.
ToneMatch® Input
The ToneMatch® connection is specifically designed for a T1 ToneMatch Audio Engine. The ToneMatch® cable is supplied with the T1 ToneMatch Audio Engine and uses a male Ethercon connector at both ends.
Analog Input
The Analog connection is a ¼ inch phone jack. You can use this for a second T1® using the T1® Analog Master output (¼ inch phone jack).
This connection is made with a standard ¼ inch jack instrument cable. This can be Tip-Sleeve or Tip-Ring-Sleeve connectors.
Set Power Stand Analog Input Trim to 3 to have approximately the same level as you would have if you had connected with the ToneMatch® connection. You may have to adjust this, but 3 is a good place to start.
Note: A T1® connected to the the Analog input will require the optional T1 ToneMatch® Audio Engine power supply.
Analog Connection from the Second T1® to the Model II Power Stand
¼ Inch Tip-Ring-Sleeve (balanced) to ¼ Inch Tip-Ring-Sleeve (balanced)
A balanced connection is preferred and will provide better noise rejection over greater distances than the unbalanced connection.
¼ Inch Tip-Ring-Sleeve (unbalanced) to ¼ Inch Tip-Sleeve (unbalanced)
This should work fine but a balanced connection (immediately above) is preferred especially if you will have cable runs in excess of 20 feet (6 meters) or if you hear line noise, hum or hiss.
Preamps
Comparison to Model I and Classic
MikeZ-at-Bose tells us:[1]
... (the preamps on the Model I are)... exactly the same as the Classic.
On the T1 ToneMatch Audio Engine they're different, but are designed to the same standard as the L1 Classic preamps.
Functionally they are basically the same in terms of frequency response, input impedance, noise performance, max gains etc.
The difference comes in how we get there. I'll try not to go into horribly boring detail. The name of the game is trade offs, and in the end the design constraints dictate the *best* type of circuit used for *this* particular situation. Here are a couple of the many factors that dictate the differences:
Gain structure. The internal components of the T1 ToneMatch Audio Engine are different that the L1 Model I / L1 Classic and need to have signals fed to them in certain ways. Different designs are more suited to the levels needed than others.
Physical layout of the circuit on the board. There are four channels in a tighter space in the T1 ToneMatch Audio Engine. Again, certain designs lend themselves to be better at this than others.
After evaluating all of the factors that go into the design of a preamp we are using another proven circuit that relies more on discrete transistors rather than op-amps. It fits our needs better for this design situation. The preamp design itself is not necessarily any better or worse. There are *many* ways to skin the cat of preamp design to achieve a desired performance.
Will it sound different? No...I certainly cannot hear a difference playing through it. Can't measure one either.
Hope this sheds some light on it.

Preamps Out
The preamp outputs are before everything except the Trim control in the signal chain. - MikeZ-at-Bose[3]. This means that these are post-trim, and nothing else (e.g. Muting) has any effect on the signal at the preamp outs.
Presets
- ToneMatch® Presets for the T1® (downloadable presets that are not installed at the factory)
- T1 ToneMatch® Presets (includes downloadable lists with cross-references to Version 2 presets).
Tuner
If you are experiencing difficulties with the tuner, here are some points to check.
- *CRITICAL*. Make sure the CH Edit button is pressed on the Channel of the instrument you are trying to tune.
- Make sure your instrument is gain staged correctly.
The tuner needs a good strong signal (at least solid green) to lock on to. - Take off/bypass any effects that affect your instrument before the signal enters the T1®.
Any modulation effects will mess things up.
- In all of our testing and experience here we have found the tuner to be as accurate and reliable as other high-quality stage tuners. The T1 tuner is fairly 'fast' in terms of tracking speed. For example, typically, Boss tuners have more 'averaging' and slower tracking speed. The needle moves up to the note you are tuning slower, but is more stable once you get up there. Another example - Peterson tuners generally track faster. They go up very fast to the note, and move around more once you get up there - this is because the instrument is actually slightly varying pitch. The tuner is tracking this behavior correctly. Both Peterson and Boss make awesome, super accurate tuners, it's just like the difference between a Strat and a Les Paul...or a Porshe and a Benz.
- The T1 tuner, as I said, is faster in its tracking, and this may take some getting used to at first. It took me a little while to become accustomed to bench tuning my basses with a Peterson strobe tuner after using a Boss for a few years.
-- MikeZ-at-Bose[4]
- "The internal send for the tuner is Pre-FX" [5]
And a hint from Bill-at-Bose
- You may already know that the ubiquitous hum you hear, that can be caused by cable grounding problems, lighting dimmers, ground loops, etc., is based in the U.S. off the 120 VAC line.
- The line cycles at 60 Hz, you can usually pick up multiples of it: 120 Hz, 240 Hz. That's right between an A and a B-flat.
- Here are the frequencies:
- A#2/Bb2 116.54 Hz
- B2 123.47 Hz
Hum louder than your note will confuse your tuner for sure.
You hear that note everywhere you go in this 'civilised' world, from fluorescent lights to refridgerator motors to your PC hard drive.

Live Application of USB in the T1 ToneMatch® Audio Engine
Hilmar-at-Bose talks about the USB interface[6]
Firstly, the T1 ToneMatch Audio Engine is designed as a convenient and powerful interface for a live musician. We try to put many useful controls directly at your finger tips so you can operate them while your playing or between songs. This basic idea has also influenced how we've implemented USB audio streaming. We try to accommodate the most common use cases (background tracks, DJ, quick recording) with the least amount of hassle & configuration work, even if that makes less common uses cases more difficult to accommodate.
USB audio in general
Hilmar-at-Bose talks about the USB interface[7]
When you plug in the T1 ToneMatch® Audio Engine into your PC it will appear to the PC as a USB sound card (USB audio device in Windows). You can play and record audio just like with any other soundcard, i.e. if you use for example Windows Media Player to play a song, the audio will be routed via USB to the T1 ToneMatch Audio Engine.
On the T1 ToneMatch® Audio Engine you can decide where you want it. You can route it either to the master (e.g. when using the PC to play background tracks) or into channel 4/5 to process it to your hearts content.
The T1 ToneMatch Audio Engine can also send audio back to the PC. You can select what you want to send. It can be either channel (1,2,3,4/5) or Aux or Master. For example you can make a little submix on the AUX bus and record that with for example Windows Sound Recorder or Audacity.
Here is an excerpt from page 30 of the ToneMatch® Audio Engine Owner's Guide

USB and Channel 4/5 Analog at the same time
You can connect the USB input to T1® Channel 4/5 for a stereo source (computer) AND an analog input to T1® Channel 4/5 at the same time. While it is unlikely you would play both sources simultaneously, you can raise and lower the outputs at the source. This allows you to control the sources applying ToneMatch® Presets, EQ, and volume using the Channel 4/5 Vol control.
Analog Connection
Latency and Digital Audio Workstation
USB audio requires a fairly complicated driver stack and hence we have decided to operate with the Windows standard drivers. That's fairly rugged but also not particularly fast, so processing sounds in real time on the PC and sending back to the T1 may or may not work depending how the computer is configured, what operating system is running, and what other processes are going on at the same time. See also: Latency and The L1®
Digital Media players and USB host
The T1 ToneMatch Audio Engine is only a USB client and requires a USB host (= PC). That means you cannot connect an MP3 player directly to the T1 digitally. The best way to connect is analog through Ch 4/5.
Stereo or Mono
Hilmar answers [8]
Tom Munch asked: Can channels 4 & 5 be assigned separately to the Aux & Master outs to send to 2 L1's?
Not really. 4/5 are immediately summed to mono and treated the always the same. You could route the left USB channel to the master, and the right USB channel to 4/5, turning the 4/5 channel volume all the way down and using a pre-fade AUX feed for 4/5 to get it out the Aux.
That's certainly a little convoluted but would enable you to route a USB source to two different L1s.

ASIO
From Chuck-at-Bose
- I'd like to offer some clarification that may or may not help. Sound cards, including the T1, depend upon 'drivers' to do what they do. ASIO/WDM/MME aren't really drivers, but driver access protocols. ASIO usually results in the lowest amount of round-trip latency (all things being equal) because, unlike the others, it bypasses the operating system (e.g. Windows) kernel...
- FWIW, I have used the T1 very successfully for recording and playback with SONAR 8 PE on my PC using WDM and ASIO. I got the best results (lowest latency, fewest dropouts, etc.) using ASIO4all. Given the zillions of variables among hardware configs, operating systems, etc., your mileage may vary. I think it's worth stating that the T1 excels as an interface for an L1 system and though it happens to work great as a basic sound card (record/playback/re-amp, etc.), there are lots of soundcards out there that do more than these basics. Their value, in my experience, is commensurate with their price tag...
- 'Hope this helps...
- Chuck [9]
USB Controller (Master) / Controllee (Slave)
USB is structured to have a controller (called a Master, Type A connector, usually a computer) and a multitude of controllees (called slaves, Type-B or Mini-B connector, i.e. T1 ToneMatch Audio Engine, Zoom H4, USB Sound Card, USB to Blutooth adapter, etc). The controllees cannot communicate with each other. A Bluetooth adaper and T1 ToneMatch® Audio Engine are in that category they will not communicate unless one or the other makes a major hardware/software change and adds the capability to become a master.

Routing Effects
|
This article addresses some interesting options you have for routing your signal through the T1® to process effects more than once. For ideas on how you can work with an external effects unit see: T1 ToneMatch® Audio Engine / Insert for External Effects |
There are several less than obvious things you can do with effects through the T1 ToneMatch Audio Engine.
Parallel Effects
If you want to swap between two sets of effects or run two sets of effects at the same time (for example: two delays, two modulation effects, two reverbs) try this.
Assume that you are using Channel 1 as the input where you want to do this:
- Set the effects you want on Channel 1
- Take a ¼ inch jack cable from the Channel 1 PreAmp Out to Channel 2 input
- Add the second layer of effects you want to Channel 2
- Now use the FX Mute buttons for Channels 1 and 2 to set which banks of effects will be used
- Channel 1 only
- Channel 2 only
- Channel 1 and Channel 2 in parallel
Serial Effects
If you want to run some effects and then add more effects in series then take the output of one or more T1 ToneMatch Audio Engine Channels to the Aux Output, then take the Aux Output and use that as the input to another T1® Channel
Assume that you are using Channel 1 as the input where you want to do this:
- Set the effects that you want on Channel 1
- Set the Aux tap to Pre
- Take a ¼ inch jack cable from the Aux Out to Channel 2 input
- Apply effects that you want applied to the output of Channel 1
- Now use the FX Mute buttons for Channels 1 and 2 to set which banks of effects will be used
- Channel 1 only
- Channel 2 only
- Channel 1 and Channel 2 in series
Foot Switch to Mute Effects
From Andy-at-Bose UK
First up hook up your vocal mic to, say, Channel 1 on the T1®. Next take a jack lead and connect it to the PRE AMP out on Channel 1. Take this lead and run it through either a keyboard style volume pedal or a make or break style footswitch. Run the signal from the pedal/footswitch into another T1® channel and set this channel up with the chosen vocal effects but make them 100% effect. Adjust the effected channel volume to get the desired blend of dry vocal to effected vocal. The pedal/footswitch will determine how much or if any signal will go to channel 2 and therefore whether or not an effect is added.
Cables
From T1 to Model II
Overview
The T4S and T1 ToneMatch Audio Engine uses a digital connection to the L1 Pro and L1 Model 1SL1 Model II Power Stands. This is labeled ToneMatch®. The T8S can connect to only the L1 Pro systems via the ToneMatch port.
The connecting cable has a male Ethercon connection at each end that looks like this.
CAT5 or CAT6 or CAT7 or CAT8 cable
If your ToneMatch® cable gets damaged or lost you can use a computer network cable type CAT5 or CAT6 or CAT7 or CAT8 cable. There's no compelling reason to choose higher category cables. All should work.
The T4S and T1 ToneMatch Audio Engine come with a Pro Ethercon cable, with robust metal connector shells and an almost memoryless 18' black cable.
However, in a pinch, should you forget the cable, or if say a huge Hammond B3 gets dropped on the cable and severs it, you can use and ordinary Ethernet cable and it will work fine.
Later in that discussion Hilmar-at-Bose tells us:
Any CAT5 (or CAT5e, CAT6, or CAT7 or CAT8) cable will work just fine without any degradation at least initially. The downsides are that most ethernet cables don't coil particularly well and that the connectors wear out over time. After a a few hundred uses you may notice the occasional drop out, at which point it's time to get a new one.
It's certainly a quick and cheap way to get a spare for an emergency.
- Bose recommends you do not exceed a fifty foot cable run.

Cable Length
Up to 50 feet
A technical note from Bill-at-Bose [10]
A 33 or 50 footer will not cause any problems, either with the digital audio (ones and zips) or the power.
The technical reason follows, for those who are interested : A 24 gauge wire (the size typically used in ethernet cables) has about 2.5 Ohms of resistance per 100 feet. The T1 draws roughly 1/4 Amp on each of two supply wire pairs (+/-18V nominal).
For a 50 foot run, each pair of wires (made up of a plus and minus lead) totals 100 feet. A quarter Amp of current across 2.5 Ohms gives, per Ohm's law, a voltage drop of less than one volt (V=IR = 0.625 Volts). Because of the margin we built into the system, it can handle this voltage drop easily.
In fact, although we don't recommend it and can't guarantee it, the digital audio has been tested up to 100 feet in average conditions (for example, no undervoltage on the AC supply at the gig), and quite happily continued to make music.
Over 50 feet
MikeZ-at-Bose added in a later discussion:[11]
Bill at Bose stated you could run 50' of ethernet cable no problem at all. Success at distances longer than that would start to depend on outside factors, for instance the voltage of your power source.
Another option for you is to run the T1 ToneMatch Audio Engine off of the optional power supply, and then run a balanced line from the Master Out on the T1 ToneMatch Audio Engine to the balanced 'analog input' on the L1 Model II. This method would be able to transmit over a hundred feet, perhaps much more.
- ¼ Inch Tip-Ring-Sleeve (balanced) to ¼ Inch Tip-Ring-Sleeve (balanced)
A balanced connection is preferred and will provide better noise rejection over greater distances than the unbalanced connection.

Power Supply
This is the power supply for the ToneMatch mixers (T1 ToneMatch Audio Engine and T4S/T8S ToneMatch® Mixers).
The T8S ships with a ToneMatch power supply because the T8S cannot draw power from an L1 Model 1S or L1 Model II Power Stand.
You will need the ToneMatch power supply to power your T1 or T4S mixer when running with an L1 Classic, L1 Model I, L1 Compact, S1 Pro System or non-Bose equipment. You will need a one of these if you have two ToneMatch mixers running into a single L1® Model II or L1® Model 1S. — details below the picture.
If you connect your T1 ToneMatch Audio Engine or T4S mixer to a L1 Model II or L1 Model 1S then the T1 ToneMatch® Audio Engine or T4S draws its power through the ToneMatch cable.
If you connect your ToneMatch mixer to an an L1 Classic, L1 Model I, L1 Compact or S1 Pro System or non-Bose equipment then you will need the ToneMatch power supply
If you are attaching two ToneMatch mixers to a single L1® Model II or L1 Model 1S then you will need this power supply to support the second ToneMatch mixer - the one connected to the Power Stand Analog Input.
See: Connecting Two T1®s to a Model II for details.
5 foot of cord from the T1 to the switching power supply, and a removable 6 foot cord from the power supply to the wall. This is very similar to a laptop power supply.
Microphone Stand Bracket (optional)

Owner Comments and Alternatives
- T1 mic stand adapter, thoughts and questions - Owners talking about the microphone stand bracket.
- Sight Lines and the T1® - Owners talking about placement of the T1® on the stage using the Microphone Stand Bracket.
Hints
- The bracket that sits parallel to the floor has a bevel on the top. The bevel should run down, facing you. If the bevel runs down away from you, the bracket is upside down and the T1 ToneMatch® Audio Engine will not sit properly on top of it.
- Secure the ToneMatch® cable to your microphone stand, above the T1 ToneMatch® Audio Engine. This will help keep it secure on the bracket and help to keep it from hitting the floor if it becomes dislodged from the bracket.
- If you use a microphone stand with a wider than usual diameter, try removing the inserts in the clamp. — Source: dberch on the Forum
Securing the T1® to the Bracket
- The bracket that sits parallel to the floor has a bevel on the top. The bevel should run down, facing you. If the bevel runs down away from you, the bracket is upside down and the T1 ToneMatch® Audio Engine will not sit properly on top of it.
- correct - bevel running down, facing you
- incorrect (upside down)- bevel on opposite side, away from you
This is how I secure the T1® to the T1® Microphone Stand Bracket[1]
- There is a velcro strap on the black ToneMatch cable.
- I use the velcro to secure the ToneMatch cable to the microphone stand just above the Microphone Stand Adapter (the thing that clamps around the mic stand).
- Then I insert the ToneMatch cable into the T1®. It locks into place.
- At this point, most people would put the T1® on the bracket and attach the other cables.
- I insert all the other cables into the T1® before I put it on the bracket. I do it this way because I have all my cables strapped to the microphone stand (I don't take them off between gigs). So there's no hanging stress from those either.
- Finally, I set the T1® on top of the bracket.
In the picture above, I am using all the inputs and the cables are heavy. But since I have all the cables secured by a velcro strap, there's no chance that the T1® will come off the microphone stand bracket.
The white cable is a network cable (Cat-5) instead of the ToneMatch® cable

Here's how I have one of my microphone stands setup. The T1® Microphone Stand Bracket is attached and I never remove it.
All the cables are also strapped to the microphone stand. I leave the cables attached all the time. This saves a great deal of time during setup and teardown.
I used a white background so that you could see the wires. Normally they don't stand out like this visually. Notice that even if the T1® were to get knocked off the bracket the cables are acting as safety tethers.

Display Panel
Outdoors
Q: Please talk about using the T1 ToneMatch Audio Engine outdoors. Will I be able to see /read the display? A: Should be no problem. The LCD display on the T1 is "transflexive". In dark conditions the blue backlight will shine through the "transmissible" part so everything is easily visible. In bright sunlight, it becomes "reflexive" just like a piece of paper. The backlight may wash out (i.e. it will not look really blue anymore) but it's still clearly visible. [2]

Design Team
In 23 years at Bose, the L1 Model II and T1 ToneMatch Audio Engine are the most lovingly designed products I have ever had the fortune to work on. More care by more experienced people went into this than anything I've been involved in.
The most minute details were studiously created. As one tiny but important example, a propriety light pipe was designed so that the light from volume knob indicators smoothly wrapped around the knob from top to side, giving the musician a clear indication of volume from any angle. The color and intensity of the light was carefully designed so that it was visible in an extraordinarily wide range of stage lighting conditions.
Here is a picture of some members of the design team when we reached the point in May of 2006 of having the proprietary folding mechanism for the Model II power stand and industrial design for the new Articulated Array speaker finally finished.
