Troubleshooting
Bad Channel
• Is the gain set correctly?
• Is the level knob turned up?
• Is the instrument switch set correctly?
(Channels 1–2 only).
• Try the same source signal in another
channel, set up exactly like the sus-
pect channel.
• Check that the stereo pan switch is set
correctly.
• Check the EQ and the low-cut switch.
Bad Output
• Is the associated level knob (if any)
turned up?
• If it’s a left main out, try unplugging
the RCA left tape output. If the prob-
lem goes away, its not the mixer.
• If a left speaker is presumed dead,
switch the left and right cords, at the
mixer's main outs. If the left speaker is
still not working, it’s not the mixer.
Noise
• Turn the channel level knobs down,
one by one. If the sound disappears,
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
• The power LED on the mixer should
come on when the power switch is on.
Check that the power connection to
the mixer is plugged in.
