Power Amplifier is Quiet / Broken?
 
I 'inherited' a new looking Peavey 1500 power amp.

The output is very very low but audible on both channels.:confused:

Nothing seems to get too hot for comfort, and all of the channel LEDs light up. The power supply seems OK, and there is a breaker, not a fuse which seems OK too.

This thing looks literally brand new.

Where do I start? I'm a small preamp person, not a power amp person.

Any help/suggestions would be greatly appreciated.

Thanks!

I don't know the PV1500 but did you look at the back, perhaps you used a wrong input or a switch might need some flipping.

Sometimes an engineer overlooks the obvious. :rolleyes:

There were these newer style connectors that combine the XLR and line inputs on the back. I was using one of the crossover outs as an in...

I've been staring at this thing on my bench for literally a year now, after testing it once.

Would have helped to download a manual I guess - - - yeesh.

It works fine.

On the brighter side...

I am curious about proper power amp diagnostics now...

Any specs, sound impression, build quality? Is it one of the newer peavey's? I guess SMPS instead of conventional PSU.
