Set the Trim control on the power stand to the 0 (zero) position. 2. Connect the audio source to the Analog Input. 3. Adjust the volume of the audio source to the desired level. 4. While playing the source, increase the Trim level until the Signal/Clip indicator glows green or yellow. 5. If the Signal/Clip indicator glows red, decrease the Trim level so that it glows only green or yellow. Using a T1 ToneMatch® audio engine and an analog input source The L1® model 1S system can operate with both a T1 ToneMatch® audio engine and an 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 connected 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. User scenarios 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.
