Troubleshooting
Bad Channel
• Is the MUTE/ALT 3–4 switch in the correct
position?
• Is the LEVEL knob turned up?
• Try unplugging any INSERT devices (Channels
1–4 only).
• Try the same source signal in another channel,
set up exactly like the suspect channel.
Bad Output
• Is the associated level knob (if any) turned up?
• If it’s one of the MAIN OUTS, try unplugging
all the others. For example, if it’s the 1⁄4"
Left Main out, unplug the RCA and XLR Left
outputs. If the problem goes away, its not the
mixer.
• If it’s a stereo pair, try switching them around.
For example, if a left output is presumed dead,
switch the left and right cords, at the mixer
end. If the problem switches sides, it’s not the
mixer.
Noise
• Turn the channel LEVEL and AUX RETURN
knobs down, one by one. If the sound disap-
pears, it’s either that channel or whatever is
plugged into it, so unplug whatever that is. If
the noise disappears, it’s from your whatever.
Power
• Unplug the power cord and check the fuse.
