Troubleshooting
Bad Channel
• Are the channels assigned to the correct mix
(1-2, 3-4, L-R )?
• Is the fader up?
• Try unplugging any insert devices from the
INSERT [4) jacks.
• Try the same source signal in another channel,
set up exactly like the suspect channel.
Bad Output
• Is the level control (if any) turned up?
• If you’re listening to the C-R OUTS [9] or
PHONES [10] outputs, has a SOURCE selection
been made?
• If it’s one of the MAIN OUTS [14], try unplug
-
ging its companion. For example, if it’s the 1/4"
output, unplug the RCA output. If the problem
goes away, it’s 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 left is still dead, it’s not the mixer.
• Unplug everthing from the MAIN INSERT [13].
Noise
• Turn the channel faders and STEREO 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.
