What is the recommended way to set the gain for a Model I system when using it with a T1 ToneMatch audio engine?

  • Make sure the power switch on the power stand is in the Off position and the remote control is disconnected

Note: The remote should be disconnected so that the ToneMatch audio engine solely controls the volume of the L1® system.

  • Make sure the ToneMatch audio engine power switch is in the Off position and its power supply is connected
  • Set the ToneMatch audio engine master volume control to 0
  • Plug one end of a 1/4" phone plug cable (not supplied) into the master output port on the ToneMatch audio engine. Plug the other end of the cable into the line-in jack of channel 3 or 4 on the L1® power stand

Note: We recommend only connecting to the line inputs of channels 3 and 4 because channel 1 and 2 mic/line inputs have volume controls, equalization and presets that could affect the ToneMatch audio engine's sound and performance.

  • Set the line-in level control on the power stand to approximately 2
    Note: In some circumstances, it may be necessary to slightly adjust the level of this initial setting to attain the desired gain structure.

Note:

Bose has revised this, and now recommends setting the level control to approximately 3.
