It hurts when I touch my arm, or my leg, or
even my head!
• You have a broken finger.
Bad sound!
• Is it loud and distorted? Turn down the signal com-
ing from the mixer or signal source.
• Is the input connector plugged completely into the
jack? Check the speaker connections and verify
that all connections are tight and that there are no
stray strands of wire shorting across the speaker
terminals.
• If possible, listen to the signal source with head-
phones plugged into the console. If it sounds bad
there, the problem’s not in the amplifier.
Noise/Hum
• Check the signal cable between the mixer and the
amplifier. Make sure all connections are good and
sound.
• Make sure the signal cable is not routed near AC
cables, power transformers, or other EMI-inducing
device.
• Is there a light dimmer or other SCR-based device
on the same AC circuit as the amplifier? Use an AC
line filter or plug the amplifier into a different AC
circuit.
• If possible, listen to the signal source with head-
phones plugged into the console. If it sounds noisy
there, the problem’s not in the amplifier.

Repair
Service for Mackie products is available at a factory-
authorized service center. Service for Mackie products
living outside the United States can be obtained through
local dealers or distributors.
If your M-Series amplifier needs service, follow these
instructions:
1. Review the preceding troubleshooting suggestions.
Please.
2. Call Tech Support at 1-800-898-3211, 7 am to 5 pm
PST, to explain the problem and obtain a Service
Request Number. Have your serial number ready.
You must have a Service Request Number before
you can obtain warranty service.
3. Keep this owner’s manual and the detachable line-
cord. We don’t need them to repair the amplifier.
4. Pack the amplifier in its original package, includ-
ing endcaps and box. This is
VERY IMPORTANT
.
Mackie is not responsible for any damage that
occurs due to non-factory packaging.
5. Include a legible note stating your name, shipping
address (no P.O. boxes), daytime phone number,
Service Request Number, and a detailed description
of the problem, including how to duplicate it.
6. Write the Service Request Number in
BIG PRINT
on top of the box. Units sent without the Service
Request Number will be refused.
7. Tech Support will tell you where to ship the amplifier
for repair. We suggest insurance for all forms of cartage.
8. You will need to contact the authorized service cen-
ter for their latest turn-around times. The amplifier
must 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, 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.
Note:
You must have a sales receipt from an Autho-
rized Mackie Dealer to qualify for a warranty repair.
