Volume Problems With My PA

[ToneWarrior]

I have a small PA that consist of two Behringer 400 watt powered speakers and a Tapco Mixer. The problem I'm having is channel one works fine but channels 2,3 and 4 don't get loud enough to hear over the band. Is there something wrong with the mixer or is there not enough power to use more then one vocal mic? Could I use a power amp with the powered speakers to give it more power? Also should the volume on the speakers be turned all the way up? Right now they are at half, I was thinking they should be turned all the way up and control the volume from the mixer.

Thanks

Have you tried plugging a mic into channels 2,3, and 4 and testing the volume WITHOUT plugging anything into channel 1 to see what happens? That ought to tell you pretty quickly if there's an issue with the other channels or not. From what you are saying, the problem sounds like the mixer but that test ought to help you narrow it down.

Yes I unplugged the channel one mic and just had a mic in channel two and still low volume. I also used the mic and cable from channel one in channel two and still the same problem.

In that case, I'd have to say it sounds like your mixer is faulty.

Ok, Thanks I was going to buy another one anyway because we need more channels.

Btw don't put a power amp into powered speakers.

Some mixers have an attenuation buttons that cut the level if you have a hot input signal. Does your board have these?

My money would be that it's not dialed in properly.

Check the gains, maybe the l/r settings

I have a feeling you're missing something fundamental. Take a picture of your board so we can see your current settings and post it here.
