Appendix A: Service Information
Repair
Service for TAPCO products is available at a
factory-authorized service center. Service for TAPCO
products living outside the United States can be
obtained through local dealers or distributors.
If your loudspeaker 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 loudspeaker’s
serial number ready. You must have a Service
Request Number before you can obtain factory-
authorized service.
3. Keep this owner’s manual . We don’t need it to
repair the loudspeaker.
4. Pack the loudspeaker 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. 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, Service Request 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 without the Service Request
Number will be refused.
7. Tech Support will tell you where to ship the
loudspeaker for repair. We suggest insurance for all
forms of cartage.
8. You will need to contact the authorized service
center for their latest turn-around times. The
loudspeaker 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
authorized TAPCO dealer to qualify for a warranty
repair.
Warranty Service
Details concerning Warranty Service are spelled
out in the Warranty section on page 15.
If you think your TAPCO Series 69 loudspeaker has
a problem, please do everything you can to confirm
it before calling for service. Doing so might save you
from the deprivation of your loudspeaker and the
associated suffering.
These may sound obvious to you, but here are
some things you can check. Read on.
Troubleshooting
No sound
• Are the level controls on the mixer or amplifier
turned all the way down? Follow the procedures
in the “Getting Started” section on page 4 to
verify that all the volume controls in the system are
properly adjusted.
• Is the signal source working (and making union
scale)?
• Are all the connections good and sound? Make
sure all the connecting cables are in good repair
and securely connected at both ends.
One side is way louder than the other!
• Are the level controls set the same for both
channels on the mixer and amplifier?
• Check the PAN control on the signal source. It
may be turned too far to one side. If you’re using
a stereo signal source, it may be delivering an out-
of-balance stereo signal.
• Try swapping sides: Switch the speaker cables
coming from the amplifier at the amplifier end. If
the other side is louder now, the problem is with
the amplifier, the mixer, or the signal source.
Poor bass performance
• Check the polarity of the connections between
the amplifier and the loudspeakers. You may have
your positive and negative connections reversed
at one end of one cable.
Bad sound
• Is the input connector plugged completely into
the jack? Make sure it is plugged all the way in.
• Is it loud and distorted? Reduce the signal level at
the mixer.
• If possible, listen to the signal source with
headphones plugged into the preamp stage. If it
sounds bad there, it’s not the loudspeaker.
• Keep practicing.
