Troubleshooting
Is the power on? Check the power switch. Make
sure the channels are assigned properly to the
crossfaders. Make sure INPUT GAIN is turned up
and output level control is turned up. Depending
on the input, check the rear panel selector
switches. Check the top panel channel selector
switches.
Make sure that MASTER TRIM on the rear
panel is turned up.
Do the headphones work with the CUE pan in the
PROGRAM position but not PFL? If so, make
sure that the channel PFL switches are engaged.
Check the CUE LEVEL control.
Check to make sure the talk switch is NOT
engaged on the microphone input.
Check to make sure that the microphone levels
are turned all of the way down if a microphone is
not being used.
Is the Mic gain turned up? Does the microphone
require phantom power? This mixer does not
provide microphone phantom power.
In general, turn down the INPUT GAIN CONTROL.
The input signal may be too loud for the input gain
control setting that you were using. If the distortion
goes away, then you need to turn down the INPUT
GAIN CONTROL.
