audio engine and an analog input source

The L1
®
model 1S system can operate with both a T1 ToneMatch
analog audio source connected to the power stand. However, keep in mind that the volume
level of the audio engine and the analog audio source is adjusted independently.
• The power stand Trim control only affects the volume level of the analog audio source con-
nected to the Analog Input. Therefore, the Signal/Clip indicator indicates the status only
of the analog input signal.
• The T1 ToneMatch audio engine has a Trim control and signal/clip indicator for each input,
a Volume control for each output channel, and a Master volume control that adjusts the
level of the ToneMatch output sent to the power stand. These controls have no effect on
the signal fed to the Analog Input.
There are many ways to set up and use this system with and without the T1 ToneMatch audio
engine. The following pages show examples of some typical user scenarios. When using the
T1 ToneMatch audio engine, refer to its owner's guide for more information on setup and
operation.
