T8S to Single L1 Pro[1]
There is a single ToneMatch port on the T8S ToneMatch mixer. You can use this
- To connect to an L1 Pro[1] ToneMatch Port using a ToneMatch Cable or Network Cable
- Note: This is the mixer LEFT output. Anything panned hard RIGHT will not be heard.
All of the Analog outputs (XLR or 1/4 inch (6.3 mm) Tip-Ring-Sleeve) still function while using the ToneMatch Port.
To run stereo, connect the second powered loudspeaker to one of the T8S ToneMatch mixer RIGHT Outputs (XLR or 1/4 inch (6.3 mm) Tip-Ring-Sleeve) to the second L1 Pro Input three. DO NOT USE an XLR to XLR cable. The output of the T8S ToneMatch mixer outputs is too hot for the L1 Pro XLR inputs.
- Alternate connection
- ToneMatch port on the T8S ToneMatch mixer to ToneMatch Power Supply for power and use the Analog Outputs (XLR or 1/4 inch (6.3 mm) Tip-Ring-Sleeve) to the L1 Pro Input three. DO NOT USE an XLR to XLR cable. The output of the T8S ToneMatch mixer outputs is too hot for the L1 Pro XLR inputs.

Quick Tips
L1 Pro Line Out
The XLR Line Output from any L1 Pro contains the sound from all inputs (1, 2, 3, Bluetooth, and ToneMatch Port). That includes
- ToneMatch Presets
- Tone Controls
- Reverb
- The signal from a ToneMatch mixer connected to the ToneMatch port including ToneMatch Presets, zEQ, Reverb, Effects.
The sound is NOT affected by the L1 Pro System EQ setting.
L1 Pro Daisy Chain
Want to connect one or more L1 Pro systems together? See L1 Pro Daisy Chain
L1 Pro System EQ
The System EQ feature on the L1 Pro systems applies an EQ preset to the master output. This is similar to a graphic equalizer on traditional analogue mixers, but it uses four presets instead for quick access. read more — L1 Pro System EQ
L1 Pro32 Half Stack
- Can I operate the L1 Pro32 with only the lower section of the line array?
- Sometimes there is not sufficient height to use the full array
- Yes
- The L1 Pro32 can be used without the upper array. This configuration is useful when a venue ceiling cannot accommodate the height of the L1 Pro32
Source: Page 7 of the L1 Pro32 Owners Guide
- For best results, ensure array is at ear level for listeners
- Unlike the L1 Model II, the L1 Pro32 automatically adjusts the level of the bass output to maintain the appropriate spectral balance.
- It’s a valid use case to use only the bottom array section. In fact, the EQ automatically adjusts to compensate.
Craig Small - Bose
- Half Stack Not Recommended for Small Gigs
Running only the lower section of the Line Array is a workaround when there isn't enough ceiling clearance to use both sections. For small gigs, turn down the volume on the L1 Pro32, don't run without the top section of the array because
- You'll need to elevate the system so the array is at ear level for the audience. Otherwise, the sound will be muffled
- You will reduce your projection over distance. The sound will drop off more over distance.
- You may need to turn up the volume louder than if you were using the full array. As a result, you increase the likelihood of feedback.
L1 Pro Emergency Kit
These are extras and spares I carry in addition to the items I know I will need at a gig.
| Item | Reason |
|---|---|
| IEC Power Cord | They got lost, and this can be used with an XLR cable to substitute for a SubMatch Cable |
| XLR cable | It's always good to have a spare. Use with an IEC Power Cord to replace a SubMatch Cable |
| 1/4-inch (6.3mm) Tip-Ring-Sleeve Cable | Connect mixers or devices with balanced connections to the L1 Pro. |
| 1/4-inch (6.3mm) Tip-Sleeve Cable | This is your basic instrument cable. It's always good to have a spare. |
| XLR Female to 1/4-inch (6.3mm) Tip-Ring-Sleeve Cable | To connect Line Level Output from an L1 Pro or third-party mixer to Channel 3 input of an L1 Pro or S1 Pro+ |
| 1/8-inch (3.5 mm) Tip-Ring-Sleeve Cable | Use this to connect the headphone output of a consumer device to L1 Pro or S1 Pro(+) channel 3 input |
| CAT5 cable | Connect ToneMatch Mixers (T1/T4S/T8S) to the L1 Pro ToneMatch Port |
| ToneMatch Power Supply | In case I need to run two ToneMatch Mixers to a single L1 Pro |
| Dynamic Microphone | This is a spare; the one to use when you have guest speakers making announcements |
| Microphone Clip | They break |
| Multi-bit Screwdriver | Tighten, loosen, everything as needed |
| Gaffers Tape | Tie down cables, or quick repairs |
| Labels with contact information | I have labels on all my gear, but it's good to have spares in case they fall off |
FAQ
General Questions
| Collapse all
What are the mid-high array and lower mid-high array made from? Metal mesh front and is rear metal or plastic?
Arrays on all units feature an extruded aluminum sleeve. Perforated grille on the front, solid on the back. Source: Craig Small
Are the column speaker arrays interchangeable between the different models? (L1 Pro8, L1 Pro16, L1 Pro32)
No. While the column arrays and extensions of the L1 Pro8 and L1 Pro16 will fit each other, no sound comes out.
Can I operate the L1 Pro32 with only the lower section of the line array? Sometimes there is not sufficient height to use the full array
Yes
- The L1 Pro32 can be used without the upper array. This configuration is useful when a venue ceiling cannot accommodate the height of the L1 Pro32

Inputs and Connections
| Collapse all
Is the Channel ToneMatch Setting (MIC/INST/OFF) like a MIC/LINE switch on other active loudspeakers? Does it change the input gain?
No. This is NOT like a MIC/LINE selector found on many other powered loudspeakers.
The Channel ToneMatch Setting (MIC/INST/OFF) affects only the ToneMatch Preset applied to the input. It does not affect input sensitivity or gain applied to the signal.
Channel ToneMatch Button: Select the ToneMatch preset for an individual channel. Use MIC for microphones and INST for acoustic guitar. The corresponding LED will illuminate white while selected.
More about ToneMatch Presets.
How do I connect a third-party mixer to the L1 Pro
If the mixer has XLR outputs
- Mixer mono out → XLR‑to‑Tip‑Ring‑Sleeve → L1 Pro Channel 3
If the mixer has 1/4-inch (6.3mm) Tip-Ring-Sleeve outputs
- Mixer mono out → 1/4-inch (6.3mm) Tip‑Ring‑Sleeve cable to → L1 Pro Channel 3
For more details, see Mixer to L1 Pro
Can I use XLR cables from my mixer into Channels 1 or 2?
You can, and it might work. Click for details
And yes, there are even pictures of this in the L1 Pro manuals.
However, using XLR to XLR connections can lead to problems.
1. Some mixers can output mic‑level on XLR — most cannot
If your mixer allows switching its XLR outputs from Line to Mic, then it may work. But this is uncommon. Using XLR → ¼″ (6.3 mm) Tip‑Ring‑Sleeve into Channel 3 is far more reliable.
2. Most mixer XLR outputs are line‑level, which is a poor match for the L1 Pro’s mic‑level XLR inputs
This mismatch can cause:
- Input clipping
- Harsh distortion
- Unpredictable behavior
3. You can sometimes “make it work,” but it’s not ideal
You might avoid clipping by:
- Turning down the mixer output
- Turning down the L1 Pro channel volume
However:
- Lowering the mixer output reduces signal‑to‑noise ratio (more hiss)
- Turning the L1 Pro channel knob very low gives almost no usable range
- Volume may jump from too quiet → too loud with tiny adjustments
4. Channel 3 avoids all of these issues
Channel 3 is designed for line‑level sources and provides:
- Proper level matching
- Lower input sensitivity (less likely to clip/distort)
- Full +24 dBu headroom
- Predictable behavior
- No ToneMatch presets
- No Reverb
- No DSP gain steps
This is why the recommended method is: Mixer mono out → XLR‑to‑Tip‑Ring‑Sleeve → L1 Pro Channel 3
Why are the 1/4-inch (6.3 mm) Tip-Ring-Sleeve Inputs on channels 1 and 2 louder than the 1/4-inch (6.3 mm) Tip-Ring-Sleeve Input on Channel 3
By design, the input sensitivity on channel 3 1/4-inch (6.3 mm) Tip-Ring-Sleeve is lower than on channels 1 and 2, so that when using line-level inputs, channel 3 is less likely to clip. You can get the same output from channel 3, but you may have to turn up the volume control higher to do it. You are most likely to notice this difference when connecting a third-party mixer to the L1 Pro. For more information see Mixer to L1 Pro
How do I connect one L1 Pro to another L1 Pro (Daisy chain)?
Use an XLR female to 1/4 inch (6.3 mm) Tip-Ring-Sleeve to connect the L1 Pro Line Out to a second L1 Pro (any model) channel three. For complete details see L1 Pro Daisy Chain
Troubleshooting

Quick Tips
L1 Pro Line Out
The XLR Line Output from any L1 Pro contains the sound from all inputs (1, 2, 3, Bluetooth, and ToneMatch Port). That includes
- ToneMatch Presets
- Tone Controls
- Reverb
- The signal from a ToneMatch mixer connected to the ToneMatch port including ToneMatch Presets, zEQ, Reverb, Effects.
The sound is NOT affected by the L1 Pro System EQ setting.

L1 Pro System EQ
The System EQ feature on the L1 Pro systems applies an EQ preset to the master output. This is similar to a graphic equalizer on traditional analogue mixers, but it uses four presets instead for quick access. read more — L1 Pro System EQ
L1 Pro32 Half Stack
- Can I operate the L1 Pro32 with only the lower section of the line array?
- Sometimes there is not sufficient height to use the full array
- Yes
- The L1 Pro32 can be used without the upper array. This configuration is useful when a venue ceiling cannot accommodate the height of the L1 Pro32
Source: Page 7 of the L1 Pro32 Owners Guide
- For best results, ensure array is at ear level for listeners
- Unlike the L1 Model II, the L1 Pro32 automatically adjusts the level of the bass output to maintain the appropriate spectral balance.
- It’s a valid use case to use only the bottom array section. In fact, the EQ automatically adjusts to compensate.
Craig Small - Bose
- Half Stack Not Recommended for Small Gigs
Running only the lower section of the Line Array is a workaround when there isn't enough ceiling clearance to use both sections. For small gigs, turn down the volume on the L1 Pro32, don't run without the top section of the array because
- You'll need to elevate the system so the array is at ear level for the audience. Otherwise, the sound will be muffled
- You will reduce your projection over distance. The sound will drop off more over distance.
- You may need to turn up the volume louder than if you were using the full array. As a result, you increase the likelihood of feedback.

FAQ
General Questions
| Collapse all
What are the mid-high array and lower mid-high array made from? Metal mesh front and is rear metal or plastic?
Arrays on all units feature an extruded aluminum sleeve. Perforated grille on the front, solid on the back. Source: Craig Small
Are the column speaker arrays interchangeable between the different models? (L1 Pro8, L1 Pro16, L1 Pro32)
No. While the column arrays and extensions of the L1 Pro8 and L1 Pro16 will fit each other, no sound comes out.
Can I operate the L1 Pro32 with only the lower section of the line array? Sometimes there is not sufficient height to use the full array

Inputs and Connections

Is the Channel ToneMatch Setting (MIC/INST/OFF) like a MIC/LINE switch on other active loudspeakers? Does it change the input gain?
No. This is NOT like a MIC/LINE selector found on many other powered loudspeakers.
The Channel ToneMatch Setting (MIC/INST/OFF) affects only the ToneMatch Preset applied to the input. It does not affect input sensitivity or gain applied to the signal.
Channel ToneMatch Button: Select the ToneMatch preset for an individual channel. Use MIC for microphones and INST for acoustic guitar. The corresponding LED will illuminate white while selected.

How do I connect a third-party mixer to the L1 Pro
If the mixer has XLR outputs
- Mixer mono out → XLR‑to‑Tip‑Ring‑Sleeve → L1 Pro Channel 3
If the mixer has 1/4-inch (6.3mm) Tip-Ring-Sleeve outputs
- Mixer mono out → 1/4-inch (6.3mm) Tip‑Ring‑Sleeve cable to → L1 Pro Channel 3
For more details, see Mixer to L1 Pro
Can I use XLR cables from my mixer into Channels 1 or 2?
You can, and it might work. Click for details
And yes, there are even pictures of this in the L1 Pro manuals.
However, using XLR to XLR connections can lead to problems.
1. Some mixers can output mic‑level on XLR — most cannot
If your mixer allows switching its XLR outputs from Line to Mic, then it may work. But this is uncommon. Using XLR → ¼″ (6.3 mm) Tip‑Ring‑Sleeve into Channel 3 is far more reliable.
2. Most mixer XLR outputs are line‑level, which is a poor match for the L1 Pro’s mic‑level XLR inputs
This mismatch can cause:
- Input clipping
- Harsh distortion
- Unpredictable behavior
3. You can sometimes “make it work,” but it’s not ideal
You might avoid clipping by:
- Turning down the mixer output
- Turning down the L1 Pro channel volume
However:
- Lowering the mixer output reduces signal‑to‑noise ratio (more hiss)
- Turning the L1 Pro channel knob very low gives almost no usable range
- Volume may jump from too quiet → too loud with tiny adjustments
4. Channel 3 avoids all of these issues
Channel 3 is designed for line‑level sources and provides:
- Proper level matching
- Lower input sensitivity (less likely to clip/distort)
- Full +24 dBu headroom
- Predictable behavior
- No ToneMatch presets
- No Reverb
- No DSP gain steps
This is why the recommended method is: Mixer mono out → XLR‑to‑Tip‑Ring‑Sleeve → L1 Pro Channel 3
Why are the 1/4-inch (6.3 mm) Tip-Ring-Sleeve Inputs on channels 1 and 2 louder than the 1/4-inch (6.3 mm) Tip-Ring-Sleeve Input on Channel 3
By design, the input sensitivity on channel 3 1/4-inch (6.3 mm) Tip-Ring-Sleeve is lower than on channels 1 and 2, so that when using line-level inputs, channel 3 is less likely to clip. You can get the same output from channel 3, but you may have to turn up the volume control higher to do it. You are most likely to notice this difference when connecting a third-party mixer to the L1 Pro. For more information see Mixer to L1 Pro
How do I connect one L1 Pro to another L1 Pro (Daisy chain)?
Use an XLR female to 1/4 inch (6.3 mm) Tip-Ring-Sleeve to connect the L1 Pro Line Out to a second L1 Pro (any model) channel three. For complete details see L1 Pro Daisy Chain
Troubleshooting
| Collapse all
The L1 Pro sounds muddy (no mid-highs, it's all bass)
Make sure the column arrays are seated firmly in the power stand
Excessive Hiss
I get excessive hiss with nothing connected to the L1 Pro inputs when I turn up the volume
The L1 Pro systems are not designed to be operated with no inputs For more details see L1 Pro Hiss
I get excessive hiss when connecting the LINE OUT from an L1 Pro to a second L1 Pro with an XLR cable
Connect the first L1 Pro LINE OUT to the second L1 Pro Channel 3 input The cable: Female XLR to 1/4-inch (6.3mm) Tip-Ring-Sleeve cable For more details see L1 Pro Daisy Chain
I get excessive hiss when connecting a mixer to the L1 Pro Channels 1 or 2 with an XLR cable

To connect two L1 Pro systems (daisy chain) to use the second system as an extension of the first
- Use an XLR female to 1/4 inch (6.3 mm) Tip-Ring-Sleeve to connect the L1 Pro Line Out to a second L1 Pro (any model) channel three
- Turn down the volume on the second L1 Pro
- Set the level you want on the first L1 Pro
- Set the volume on the second L1 Pro to suit the application
- Note: Running two L1 Pros daisy chained in close proximity offer little tangible benefit and can cause issues with multiple source interference. See Dual Mono for details.
- Note
The Line Out is post-fader. That is, it is the combined signal of all inputs and ToneMatch processing, EQ and Reverb. That includes inputs, 1, 2, 3, Bluetooth, and ToneMatch Port (used for T4S/T8S ToneMatch® Mixers).
The Line Out is pre-System EQ. That is, the signal at the Line Out is flat. It is not affected by the setting of the System EQ switch. [2]
This applies to any two L1 Pro systems (L1 Pro8, L1 Pro16, L1 Pro32).
- Second L1 Pro Louder than the First
Because the output level of the first L1 Pro Line Out is post-fader (see above) is higher than the original source. If you set the volume controls on the second L1 Pro to the same settings as the first L1 Pro, the second one will be louder. To get the levels the same,
- Turn down the volume on the second L1 Pro
- Set the level you want on the first L1 Pro
- Set the volume on the second L1 Pro to suit the application. Do that by ear.
- Dual Mono
When you run the same sound through two L1 systems, you should consider the consequences, both good and bad. See Dual Mono for details.
