Repair, Noise/Hum | Tapco pmn manual

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.
