Troubleshooting
No audio at the line output
Check all connections to the unit. For example, check that all necessary
inputs and outputs are plugged into the same channel.
Check the setting of the LEVEL control. Turn clockwise to increase the output
level
Check the setting of the gain control. Turn clockwise (mic mode) when using
a microphone source. Turn anti-clockwise (line mode) when using a line-level
source.
Check that the FRONT switch is set to the desired position. This switch
should be depressed when the audio source is connected to the front combo
connector.
Check that the DIGI switch is set to the desired position. The switch should
be depressed when the audio source is via the digital module.
Check whether the insert loop is in use. Set the INSERT switch to the
default position (not depressed); if line output signal becomes present, this
indicates a problem with connections to the insert loop or with the external
equipment in the loop.
