L1 Model II This information is applicable to the L1® Model II
T8S This information is applicable to the T8S ToneMatch® mixer
T1 This information is applicable to the T1 ToneMatch® audio engine

This is an example of how you can connect a T1 ToneMatch Audio Engine to a T8S ToneMatch mixer to two L1 Model II systems.

This assumes that you will run the T1 ToneMatch Audio Engine output as mono.

Connnect the T1 ToneMatch Audio Engine Master Output to T8S ToneMatch mixer Aux Input Channel 9

The output from the T1 ToneMatch Audio Engine is a balanced mono 1/4 inch (6.35 mm) Tip-Ring-Sleeve and the input on the T8S ToneMatch mixer is a balanced mono 1/4 inch (6.35 mm) Tip-Ring-Sleeve so use a cable like this.

T8S ToneMatch mixer Aux Input Settings

Bose engineered the T4S/T8S ToneMatch mixers to have four (T4s) / eight (T8S) full-function channels and two Auxiliary inputs. The Aux inputs 5/6 (T4S) or 9/10 (T8S) are routed directly to the Main Output.

You can use the Pan and Level adjustments accessible through the PAN/AUX menu. There are no changes to routing, or signal processing available. Only T4S/T8S channels one through four (T4S) / channels one through eight (T8S) can be routed to the Aux Outputs.

The Aux inputs are useful for sources that have their own volume and signal processing (e.g. EQ or effects). They are similar to an effects return channel on other mixers. Use the Master Volume to raise and lower the volume of the Aux inputs in sync with the other channels. To change the volume of the Aux inputs relative to the other inputs you can use the AUX/PAN Level (soft menu), or on the source device.

On the T8S ToneMatch mixer on the PAN/AUX setting for Aux Input (Channel 9) set the Pan to Left, Right, or Center as required. Center will send the T1 ToneMatch Audio Engine output to both L1 Model II systems.

Introduction

Connect a T8S ToneMatch mixer to two L1 Model IIs or two L1 Model 1S or one of each.

Recommendation
If you are panning everything up the middle like a traditional front of house setup, set up the L1 systems at least 20 feet (6 meters) apart. If you pan each sound source to only one L1 system, this recommendation does not apply. For more information see: Stereo / Mono / Distributed Systems
  • Connect the ToneMatch Power Supply to the T8S ToneMatch mixer for power.
  • Always use the ToneMatch Power Supply connected to the T8S ToneMatch mixer ToneMatch port.
  • Do not use the ToneMatch port to connect to a L1 power stand. The T8S ToneMatch mixer draws more power than the L1 power stand can supply.

Analog input trim (volume, or gain) control

Setting the trim level on the Model II Power Stand is a one-time step. Once you have matched the output of the ToneMatch mixer to the input of the L1 you don't need to adjust it again.

T4S/T8S ToneMatch Mixers
  1. Connect the T8S ToneMatch mixer Main Output to the L1 Model II Analog Input
  2. Set the Analog Input trim to 9:00 o'clock. Control the volume with the Master Volume on the ToneMatch mixer.

    If you set the input trim higher, you will have excessive line noise.
  3. If the Signal/Clip indicator glows red, decrease the Trim level so that it glows only green or yellow.
For third-party mixers
  1. Set the Trim control on the power stand to the 0 (zero) position.
  2. Connect the third-party mixer Main Output to the L1 Model II Analog Input
  3. Adjust the volume of the third-party Main 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[1][2]. The exact value (-18 dBFS to -20 dBFS) may vary depending your location[3].
    • Refer to the manual for the third-party for details.
  4. If the Signal/Clip indicator glows red, decrease the Trim level so that it glows only green or yellow.
