Aux Inputs

The T4S (5/6) and T8S (9/10) Aux Inputs, are routed directly to the Master Output buss.

We cannot route them to different channels or Aux outputs. You can control Pan and Level sent through to Master.

There's no other processing available (e.g. Presets, EQ, Effects).

Aux Outputs

T4S/T8S

This is an overview of using the Aux Outputs on the T4S and T8S ToneMatch® mixers. You can use the Aux outputs for monitors, remote speakers, or recording.

The steps are the same for the T8S and T4S.

T4S

Setting up monitors example

Connect your monitors to the T8S Aux Outputs. On the T8S you have four Aux Outputs. You can direct any channel to one of the Aux Outputs to create a monitor mix. As you assign a channel to an Aux Output, you can set the level and make the Aux send from the channel:

Dry : After Preamp

The only control that has an effect on the signal is the channel trim.

Pre : With EQ and FX

All settings for Preset, zEQ, ParaEQ, effects are sent through to the Aux output. The volume is controlled by the Level setting in this menu. Volume is not affected by the channel volume control. Reverb available for Aux 1 output only.

Post : After Fader

Same as Pre (above) except the volume is controlled by the channel volume control.

Select a Channel you want to direct to one of the Aux outputs. In the image below the Channel 1 CH Edit button is selected.

Turn the Rotary Selector to PAN/AUX

Turn the left most button under the display Menu to see your options. You can choose Pan, Aux Input, or one of the Aux Outputs

This is how it looks on the T8S when you turn the menu far enough to see all four Aux Outputs. On the T4S there are two Aux Outputs.

In this picture, we have chosen to direct Channel 1 to Aux 1. The level is 50% and the Tap is set to Pre

In this picture, Aux 1 is selected and you can choose if you want the Tap point to be Dry, Pre, or Post

Please see T8S Aux Send Channel Inputs to Different Aux Outputs for a detailed example.

Reverb on Aux 1

There are two reverb systems in the T4S/T8S ToneMatch® Mixers

1. Main reverb for channels 1 through 4 (T4S) and 1 through 8 (T8S)
   1. Turn Rotary Selector to Global/Reverb Type
   2. Menu: Main (that's the default)
   3. Set the Type, Time, and Balance
   4. For each individual channel (CH EDIT Button)
      • Turn Rotary Selector to Reverb
      • Menu: Main (that's the default)
      • Set Mix, Bright
2. Aux 1 Reverb
   1. Turn Rotary Selector to Global/Reverb Type
   2. Menu: Aux 1 (you have to turn the Menu button to see it)
   3. Set the Type, Time, and Balance
   4. For each individual channel (CH EDIT Button)
      • Turn Rotary Selector to Reverb
      • Menu: Aux 1 (you have to turn the Menu button to see it)
      • Set Mix, Bright

No Reverb on Aux 2(,3,4)

Question

Why is there no Reverb on the Aux 2, 3, 4 output of the T8S?

Answer

The T8S mixer has lots of different effects units and normally they are unique to each channel. That means that the T8S mixer has 4 individual dynamic processors, 4 modulators (chorus flanger, phaser, tremolo), 4 EQs, 4 parametric EQs, 4 delay processors. The only exception is the reverb, which is shared by all channels.

The output of the shared reverb processor contains the reverb portions of all 8 channels. If we send that to an Aux output, you'd hear the reverb portions of all 8 channels and not only the channel that you are interested in. In most cases, this is probably not what you want. That is why we cannot use the main reverb processor for the Aux Outputs.

Aux is also a per-channel control. That means if you turn up Aux 1 send the of a channel, you expect to hear signals from channel 1 and only from channel 1. This thinking applies to each of the channels and aux sends.

We have a separate reverb processor for Aux 1. If you use it, you hear reverb in Aux 1, and only Aux 1.

If we shared Aux 1 reverb with the other Aux channels, you would hear the reverb from all the Aux channels in every Aux output. That is why there is no reverb on Aux 2, 3, 4 output of the T8S

Workaround

Try using Digital Delay instead of Reverb for your vocals.

Digital Delay

Time: 100 ms

Mix: 15% - vary up to 30%

Fdbk: 0% - vary up to 10%

You should have better intelligibility and move the vocals out in front of the backing tracks.

Unlike Reverb, Digital Delay processing can be routed to ToneMatch Mixer Aux outputs.

Additionally, the T4S/T8S offers two (T4S) and four (T8S) Aux sends, two Aux inputs, two ToneMatch outputs for digital audio with remote power (T4S), USB-A and -B for USB drive playback or PC/Mac interfacing, a dedicated headphone jack, and ¼” TRS analog outputs.

Convenient Gig-Ready Features
Rugged and ready to go, the T4S/T8S includes a protective magnetic cover and a bottom insert allows you to use standard mounting accessories to keep the T4S/T8S within reach.

What are the differences between the T4S and the T8S?

The T4S and the T8S both have the same compact interface, tactile knobs and advanced digital audio processing, yet the T8S gives you an expanded channel count with four more mic/line inputs and a total of four Aux sends. The T8S also includes an output meter to visually monitor your output level. The T4S can receive power and send digital audio to L1 Model II or L1 Model 1S products when using the included ToneMatch cable. The T8S comes standard with a universal power supply and does not offer a ToneMatch link.

What are ToneMatch presets, and what are their benefits?

ToneMatch presets are designed for specific instruments and microphones for use with the L1 Model 1S/II system, S1 Pro or F1 system. ToneMatch presets are available for each channel and instantly bring you closer to the true sound of your voice or instrument – all at the touch of a button. When you select a proprietary ToneMatch preset for your microphone or instrument, you are tapping into a powerful technology, available only from Bose.

What is the concept behind zEQ, and what are the benefits?

Ordinary tone controls are generic by design: “High,” “Mid” and “Low” controls are spread out across the entire musical spectrum. Proprietary zEQ automatically shifts the range of these controls so that they correspond directly to the range of your voice or instrument. zEQ gives you more precise control over your tone, making it easy to fine-tune your sound.

What is the benefit of the ToneMatch ports on the T4S?

When used with ToneMatch cables, connect the outputs of the T4S to one or two L1 Model 1S/II units via their ToneMatch ports. The user may enjoy the benefits of digital quality audio while alleviating the need for an additional power supply and excessive wiring when used with the L1 Model 1S/II system. (Note: this is for the T4S only, the T8S must be used with a power supply, although the T4S can be powered using the accessory ToneMatch power supply when not being used with an L1 system.)

What is the proper method for setting the gain on the T4S/T8S ToneMatch mixer?

Adjust the output volume of the source instrument to normal operating volume, or sing into the microphone using your loudest level. Make sure that the Master volume and the channel volume on the T4S/T8S are set to 0. While playing your instrument/audio sources as loudly as you would during a performance, turn the Trim control on applicable channel of the T4S/T8S clockwise until the signal/clip indicator glows green. If the indicator flashes red or glows steady red, turn the trim control counterclockwise to decrease the level until it’s most always green.

What are the two Aux outs on the T4S and 4 Aux outs on the T8S?

These are direct output signals that can be taken pre or post mix and connected to a number of different devices including personal monitors, amplifiers or recording devices. Aux outputs accept ¼” TRS balanced cables.

17" 18" 18

How many inputs does the T4S/T8S ToneMatch mixer have, and what type are they?

18"17"

Inputs 1-4 (1-8 with the T8S) are analog inputs channels with a combination input connector. This connector supports either balanced XLR audio cables or ¼” balanced (TRS) or unbalanced (TS) cables. Easily connect multiple sources with the added flexibility of accepting either balanced XLR audio cables or ¼” balanced or unbalanced cables.

Aux input channels 5&6 (9&10 T8S only) accept a ¼” balanced or unbalanced cable. Both inputs are independent of each other and can have separate volumes and pans. These stereo inputs are useful for connecting the outputs from PC audio interfaces, mixing consoles and keyboards/synths.

How can you verify the version of ToneMatch presets that are on the T4S/T8S?

Access the global preferences menu to confirm which interchangeable ToneMatch preset banks are loaded on the system. Use the rotary encoder to select the global Prefs mode. Press Menu button to select menu list, then rotate the Select button to scroll through the list and highlight the ToneMatch description.

What is the process for updating the T4S/T8S with new ToneMatch presets?

The T4S/T8S is equipped with a USB interface that may be connected to a PC. Check www.Bose.com/musicians for periodic updates on preset availability.

What is a user-defined scene?

The T4S/T8S allows the user to easily store, recall and edit performance scenes (a snapshot of the complete state of the unit) into five user-defined scenes. User-defined scenes help achieve consistent sound with minimal configuration. After editing a Bose scene to your preference, you may re-save it as a user-defined scene, allowing you to easily recall it later. This greatly reduces the amount of configuration required.

What is a shared scene?

A shared scene is a single user scene that you can send out of the T4S/T8S to a PC when using the L1 updater software. This allows you to share the scene with other members of the user community. To obtain software, please go to www.Bose.com/musicians.

Does the T4S/T8S ToneMatch mixer have built-in effects? What are some of the features and applications where they may be used?

Yes. Below is a list of effects that users may independently assign/adjust for any or all channels. The user also enjoys discrete control over designated parameters for each respective channel.

Effects

Modulation

Chorus 1: Brite - Shimmering chorus that works well with acoustic instruments. Includes adjustable mix, depth and speed parameters.

Chorus 2: Warm - Like Chorus 1 but with slightly less high frequencies. Includes adjustable mix, depth and speed parameters and works well with electric guitars and basses.

Chorus 3: Dark - Like Chorus 2 but with less high frequencies for a darker tone. Includes adjustable mix, depth and speed parameters, and works well with electric guitars and basses.

Flanger 1: Tape - Tape-style flanger with no feedback. Includes adjustable mix, depth and speed parameters, and works well with electric guitars and basses.

Flanger 2: Feedback - Same as Flanger 1 but with preset Feedback effect.

Phaser 1: Stomp - Classic “stomp box”-style phaser. Features a preset wide speed with variable speed and feedback parameters, and works well with electric guitars/basses and keyboards.

Phaser 2: Rack - Classic “rack”-style phaser. Features a positive mix type with variable speed and feedback parameters, and works well on electric guitars/basses and keyboards.

Phaser 3: Warm - Vintage-style phaser. Features a positive mix type with variable speed and feedback parameters, and works well as an effect on electric guitars/basses and keyboards.

Phaser 4: Bright - Phaser with no bass. Features a positive mix type with variable speed and feedback parameters that works well on electric guitars and keyboards.

Tremolo - Vintage-style tremolo effect with variable speed and depth parameters that works well as an effect on guitars and keyboards.

Delay

Choose from analog, digital or tape delay. Independently assign/adjust the delay settings for desired channels with discrete control over the mix and feedback time parameters for each channel. For example, the user may select a tape delay for the vocal on Channel 1 while selecting an analog delay for the guitar on Channel 2. Set your delay time with the center knob or use the tap tempo feature by pressing the center knob at desired tempo.

Digital Delay - Digital delay effect where the repeats remain uncolored. Features adjustable mix, time, and feedback parameters, and may be used on guitars, drums or vocals.

Analog Delay - Classic analog delay effect, where the repeats continuously deteriorate. Features adjustable mix, time and feedback parameters, and may be used with guitars, drums or vocals.

Tape Delay - Vintage-style tape delay effect, where the repeats deteriorate even more than analog delay, and may be used with guitars, horns, harmonica or vocals.

Reverb
The T4S/T8S allows access to a global reverb type that may be applied to both the master output and Aux outputs, or you can select separate reverb types for the master outputs and Aux outputs. The reverb types are plate, small, medium, large and cavern. Control decay time and level of reverb signal sent through master output. Please keep in mind that once you select a global reverb type to be used among any or all channels, you may control the mix and brightness of each channel. However, the type of reverb may only be altered for all channels. This is achieved through adjusting the Reverb Type mixer mode.

Plate - Creates the ambience of a medium-sized space. Features adjustable time and balance (ratio of early/later reflections) parameters and may be used with guitar, horns, percussion instruments and vocals.

Small - Creates the ambience of a small-sized space. Features adjustable time and balance (ratio of early/later reflections) parameters and may be used with guitar, horns, percussion instruments and vocals.

Medium - Creates the ambience of a medium-sized space. Features adjustable time and balance (ratio of early/later reflections) parameters and may be used with guitar, horns, percussion instruments and vocals.

Large - Creates the ambience of a large-sized space. Features adjustable time and balance (ratio of early/later reflections) parameters, and may be used with guitar, horns, percussion instruments and vocals.

Cavern - Creates the ambience of an extremely large space. Features adjustable time and balance (ratio of early/later reflections) parameters, and may be used with guitar, horns, percussion instruments and vocals.

Dynamics Processing

Compressor 1: Light - Compressor featuring a preset low compression ratio with variable threshold and gain parameters. May be used as a general-purpose compression 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 and may be used with basses, guitars, keyboards, vocals or other instruments requiring subtle level control.

Compressor 3: Heavy - Compressor featuring a preset high compression ratio with variable threshold and gain parameters and may be used with loud instruments such as horns and drums, vocals or other instruments that require more aggressive level control.

Noise gate - adjustable threshold and speed independently assignable for each channel. Controls extraneous noise from open microphones or hot instrument pickups from being introduced into the system.

Limiter – User-adjustable threshold and gain settings are independently assignable for each channel.
Prevents input signals from overloading, helping to maintain consistent gain staging.

De-Esser – User-adjustable threshold and gain settings are independently assignable for each channel.
Compression useful in reducing high-end frequencies associated with vocal sibilant sounds.

Kick Gate - The Kick Gate is a Bose proprietary technology that allows you to drive your kick
drum to loud levels while avoiding microphone feedback.

Step 1: Connect an appropriate microphone. It is imperative that you gain
stage the microphone correctly. Your hardest kick hits should put the LED
clip meter solidly in the yellow, just shy of the red.

• Step 2: Activate the kick gate. Use the default settings initially. Turn the
volume of the system up to desired performance level.

• Step 3: Play the softest that you will play in the performance. You should
clearly hear these kick hits.

• Step 4: Playing softly, raise the
threshold knob until you hear some of your
kick hits get cut off. Back the threshold down 3db from this point.

• Step 5: Play the kick drum as you normally would. Reduce ‘Tightness’ to
add more boom to your sound.

• Step 6: Enjoy your kick drum!
 

Can you assign multiple effects to any or all channels?

Yes. The user may run multiple effects on one channel while simultaneously running a set of completely different effects on each of the other channels. Each effect type has designated user-adjustable parameters, which also may vary from channel to channel.

Can I create a sub mix to send to a house PA system or recording device?

Yes. The Aux outputs on the T4S/T8S allow you to send selected input channels to separate mixes by accessing the Aux menu under PAN/AUX. You then can determine if the signal will be Dry (after preamp), Pre (includes EQ and FX) or Post (after fader).

Does the T4S/T8S have amp modeling capability?

No. Distortion must be produced first and then fed into the T4S/T8S as a clean, non-clipping signal. To achieve distortion, the guitarist can use a few methods:

Inline devices: One popular method would be to use any of the effects pedals on the market or use a DSP-based amplifier modeler that models the tone produced by amplifier tubes, guitar transducers and guitar amplifier speaker cabinets.

Miking a guitar amplifier: Another method would be to use a guitar amplifier, and mic the speaker as closely as possible. The trick here is to run the amplifier at the lowest level at which the correct tone is attainable but does not diminish the benefits of the ToneMatch setting. Louder amplifiers can be located and miked offstage. Miking small, low-watt amplifiers is a better technique for this method.

Use a loading device: Some electric guitarists may prefer to use their amplifier's output as an input signal into the power stand. Before doing this, they must use a load device, such as a "Plate Soak" or a "Hot Plate" to give a line-level output suitable for the input stage of the T4S/T8S.

Use the "line output" of a guitar amplifier: Some amplifiers have this option, and it may be suitable for some guitarists. The only suggestion here is to turn the volume of the amplifier down so only the ToneMatch setting is heard.

Refer to the Bose website and Portable PA Community at www.Bose.com/musicians for more information on interfacing instruments with the ToneMatch mixers.

Can I purchase the T4S/T8S and use it with other Bose systems?

Yes. The T4S/T8S is available for purchase separately or may be used with an L1 Model 1S/II system, S1 Pro or F1 System. When the T4S/T8S is fused with one of the products, the ToneMatch settings are optimized for the loudspeaker. The T4S/T8S can be connected analog any number of amplifiers or loudspeakers. A power supply is required to run the mixer which is available through Bose or authorized dealers of Bose products.
