T1 ToneMatch® Audio Engine

The following technique provides a way :

  • To supply the Front of House engineer with four distinct signals (direct outs) that are not modified by any changes to the T1 ToneMatch Audio Engine settings (except for the T1 Input Trim controls)
  • To use of the T1 Master Output for a monitor mix.


  • Up to four dry balanced direct output signals for the house system. These signals will not contain any ToneMatch preset, zEQ, Para EQ, Comp/Gate, Modulation, Delay or Reverb.
  • The FOH engineer will have full control of the FOH sound.
  • The following T1 controls will not affect FOH: Mute buttons, Input Volume controls, Master Volume control, FX Mute buttons, T1 Rotary Selector (except for the Aux position)
  • One monitor mix via the T1 Master Output containing any ToneMatch preset, zEQ, Para EQ, Comp/Gate, Modulation, Delay or Reverb that you have assigned to any of the T1 channels
  • Control of your monitor mix via the T1


  • The input Trim control settings should not be changed once they have been set for proper gain staging. Any changes to the Trim controls will affect the Preamp OUT signals thus affecting FOH
  • The T1 power switch should never be turned on or off while the T1 is connected to the "festival sound system" until the sound engineers have muted all related inputs. Big bangs and pops will ensue with possible (expensive?) damage to the sound system. This is true for the FOH console and the monitor console if one is in use.
  • Most "festival" monitor systems will have a graphic EQ already adjusted for best gain before feedback. This should minimize feedback issues with your vocal microphone.
  • Acoustic Guitars with internal microphones and certain pickups may encounter feedback issues you would not necessarily have encountered with the L1 positioned behind you since the monitor speaker will likely be positioned in front of you. Consider altering the positioning of the monitor speaker as one option should you encounter feedback. Other options include: changes to the T1 EQ settings including the Para EQ, changes to the monitor graphic EQ by enlisting the assistance of the monitor engineer, a guitar sound hole feedback plug.
  • Your usual favorite ToneMatch presets may or may not provide the sound that you are accustomed to hearing from your L1. If you have access locally to a "triple system" (especially monitor speakers) you may want to experiment and save some optional scenes in your T1 prior to flying out to a festival.
  • Channel 4/5 Aux must be set to Dry
  • Channel 1, 2 and 3 Aux must be set to Mute
  • You must explain to the sound engineer that the T1 Master Output is for the monitor mix only and that the other outputs are not to be sent to your monitor.

Equipment required

  • T1 ToneMatch Audio Engine
  • T1 ToneMatch® Audio Engine power supply
  • Non polarized AC cable for T1 power supply (included with the T1 power supply)
  • Musical instruments and associated cables and accessories
  • Microphone(s): bringing your own microphone is the only way to ensure you will be performing with a microphone with which you are comfortable.
  • Microphone cable: yes they will likely have microphone cables you can use (see Note at end of list).
  • ¼ TRS male to male XLR cables (for one T1 up to 5 cables may be required, 5 feet would be a good length.) See: Cables
  • Something to secure your T1 to a stool, a chair, a microphone stand or a music stand. (T1 microphone stand adapter, gaffers tape, Velcro...)
  • Something to secure all the cables (connected to the T1) to a leg of the stool/chair, music stand... (double sided Velcro, string, gaffers tape)
  • Notes: All your cables should be clearly marked for easy identification during tear down at the end of your set. This can be something permanent or it can be temporary with colored tape with your initials. If you bring you own microphone(s) then bringing your microphone cable(s) as well would minimize cable mix ups at tear down (all cables connected to the T1 are your cables). Of course bringing everything contained in the list may not be practical in some situations.

Connections to the T1 ToneMatch® Audio Engine

  • Connect your instrument(s) and vocal microphone(s) to the T1 as you would if you were using your L1
  • Connect a ¼ TRS male to male XLR cable to each T1 Preamp OUT connector as required
  • Connect a ¼ TRS male to male XLR cable to the T1 Aux Output if you have an instrument connected to your T1 channel 4/5
  • Connect a ¼ TRS male to male XLR cable to the T1 Master Output
  • Connect the T1 power supply to the T1
  • Note: up to five ¼ TRS male to male XLR cables will be connected between the T1 and the house system (one as a Preamp OUT (a.k.a. Direct Out) for each input being used and one Master Out for a monitor mix).


This is a ¼ TRS male to male XLR cable. You may need up to five of these depending on how many T1® Channels you are using.

Should you or should you not use a ToneMatch preset when using the ToneMatch Mixer[1] or T1 ToneMatch Audio Engine with other systems?

ToneMatch® presets optimize the sound of a microphone or instrument when used with an L1 system. So this might lead you to conclude that a ToneMatch preset shouldn't be used with other systems.

But that wouldn't be quite right.

If that other system had a similar "voicing" or tonal response as the L1 then you would expect the ToneMatch® preset to be of value with that other system.

There is potentially a class of systems that fit this description. The L1 system is voiced to make high quality commercial recordings sound the best we know how. Some studio systems are voiced the same way, as they are where those recordings were mixed.

Thus, on some studio systems, you should expect ToneMatch® presets to be of value.

Other systems, including PA speakers and monitor speakers are voiced in an almost random and widely varying way, in our experience. Thus, as MikeZ points out, it's impossible to say whether a ToneMatch® preset will help or hurt.

With best regards,

MikeZ Comment to which Ken refers above.

The whole thing with using the ToneMatch Mixer[1] or T1 ToneMatch Audio Engine with other systems is that we don't really know how it's going to sound since all big house systems are different. Generally, folks have reported the presets work well - so I think you will be fine with them. If the presets are not working, you can always go Flat using the Acoustic Guitar zEQ for adjustments (last preset in the Acoustic Guitar bank). And you'll still have all of the effects and tools in the T1 at your disposal.

T1 ToneMatch Audio Engine Power Supply Required

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.

ToneMatch power supply

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.
