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 devices.
• 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
headphones plugged into the console. If it
sounds noisy there, the problem is not in the
amplifier.
Repair
Service for TAPCO amplifiers is available
at a factory-authorized service center. Service
for TAPCO amplifiers living outside the United
States can be obtained through local dealers or
distributors.
If your amplifier needs service, follow these
instructions:
1. Review the preceding troubleshooting
suggestions. Please.
2. Call Tech Support at 1-877-827-2669, 7 am to
5 pm PST, to explain the problem and obtain a
Service Request Number. Have your amplifier’s
serial number ready.
You must have a Service Request Number
before you can obtain factory-authorized.
3. Keep this owner’s manual and the detachable
power cord. We don’t need them to repair the
amplifier.
4. Pack the amplifier in its original package,
including endcaps and box. This is
VERY
IMPORTANT
. When you call for the Service
Request Number, please let Tech Support know
if you need new packaging. You can order new
packaging through our parts department.
TAPCO 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, RA number, and a detailed description of
the problem, including how we can duplicate it.
6. Write the Service Request Number in
BIG PRINT
on
top of the box. Units sent to us 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. We’ll try to fix the amplifier within five business
days. Ask Tech Support for the latest turn-
around times when you call for your Service
Request Number. The amplifier must be
packaged in its original packing box, and must
have the Service Request Number on the box.
Once it’s repaired, we’ll ship it back the same
way in which it was received. This paragraph
does not necessarily apply to non-warranty
repair.
Note:
You must have a sales receipt from an Authorized
TAPCO Dealer to qualify for a warranty repair.
