20 Most Recent Harbinger APS 15 Powered PA Speaker Questions & Answers

Where can I buy a horn for my speaker?

probably shorted the integrated amp chip...they are not worth the trouble to fix..buy some good equipment.

eBay or an electronics component store https://www.google.com/search?q=parts+for+a+harbinger+vari+v2115+amplfier ..

It could be a number of things. Does the head light up when turned on? Are the controls on the channel turned up? Is the master turned up? Have you checked continuity on the cables? Have you tried the speakers with another amp, or the amp with other speakers? This will help narrow down the problem.

We sell this Same PA at the music store I work at, and I know that Any normally open momentary switch will work if it's Not working, then either the switch or cord is defective or we have had to service a few of these, never for that problem tho? So I guess it could be the input jack on the PA ? Hope that Helps?

If you do not have training in electronics you can cause serious damage to yourself trying to fix this. You will need to take this into the shop.

The most likely case is that one of the main output transistors (if which there are many) is shorted. When the protect circuit senses DC on the final output, it will not allow the output relay to come on to protect the speakers from raw DC. With the power removed, you can check between each outputs Emitter and Collector and you will probably find close to zero ohms. From that point you need to unsolder each of the pins of the bad channel until you find the shorted device(s) and replace them.
