Mackie M2000, M3000, M4000

M-Series

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.

Tech Support will tell you where to ship the ampliﬁer

for repair. We suggest insurance for all forms of cartage.

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.
