FAULT FINDING

No sound from mixer
Check that the unit is powered on, and that an audio signal is connected
to a channel input.
Check that the PHONO/LINE switch is in the correct position for the
type of music source connected, (PHONO for turntables, LINE for CD
players.
Check that the EQ controls are in the centre position.
Raise the input channel LEVEL control until you see the meters
displaying the music signal (also check that the CUE/MASTER button is
up).
Raise the channel fader, and ensure that the crossfader is towards the
channel that is receiving the audio signal.
Raise the level of the MASTER, MONITOR or HEADPHONE level
controls depending on what output your amplifier is connected to, or if
you are monitoring through headphones.
If the FILTER/FXLOOP switch is on, check that the FXLOOP ON switch
(above the MASTER level control) is up.
External effects unit can't be heard
Check that it is connected correctly and switched on; FX LOOP SND
on the rear panel of the mixer should be connected to the input socket
on the external effects unit, and the output from the effects unit should
be connected to the FX LOOP RTN.
Check that the FXLOOP switch is on (pressed down), and that the
FILTER/FXLOOP switch below the channel fader is ON.
Signal is loud and distorted
Check that the audio source is connected to the correct input; i.e. don't
connect a CD player to the PHONO input.
Adjust the channel input LEVEL so that the Channel meters peak the +3
or +6 LEDs. If the red LED comes on, turn down the channel LEVEL
control.
