check out the following troubleshooting tips and do your
best to confi rm the problem. Visit the Support section of
our website (www.mackie.com) where you will fi nd lots
of useful information such as FAQs, documentation and

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 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 or PHONES
outputs, has a SOURCE selection been made?
• If it’s one of the MAIN OUTS, try unplugging its
companion. For example, if it’s the 1/4" LEFT
MAIN OUT, unplug the RCA output. If the prob-
lem 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 problem stays on the left, it’s not the
mixer.
• Unplug everthing from the MAIN INSERTS.
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.

non-factory packaging.

will be refused.
7. Tech Support will tell you where to ship the unit for

age.
8. You will need to contact the authorized service
center for their latest turn-around times. The unit
should be packaged in its original packing box, and
must have the Service Request Number on the box.
Once it’s repaired, the authorized service center
will ship it back by ground shipping, pre-paid (if it
was a warranty repair).
Note: Under the terms of the warranty, you must ship or
drop-off the unit to an authorized service center.
The return ground shipment is covered for those
units deemed by us to be under warranty.
