Question:

PA amp + speakers

by  |  earlier

0 LIKES UnLike

Hello, I have a small carlsbro pa + speakers. The problem is - all i'm getting from the rear speaker outputs (4 ohms min) is constant white noise?

I have checked the speakers with a different amp, they are fine. Plus I have tried the mono output on the front panel, this works too.

The noise happens even when all the volume dials, includind the main volume are turned to 0. I have also tried different cables, no success.

 I notice when I turn off the power switch, as the power fades I can hear my mp3 player working for a split second.

I have just opened it up and all the soldering looks good.

Any suggestions

regards Matt
