PA system help

[Bassangel44]

Hey Guys, a friend a mine just recently gave my band a mixer to use on our quest to get a functioning PA system. So we bought a speaker (Kustom KPC215 H 2x15) with another one the way as soon as we get the money. But we got the speaker today and went to test the mixer out, only to realize that it was an unpowered mixer. So can we just buy a power amp to run between the mixer and the speaker? And would we need a power amp for each speaker that we would have, or can we run multiple speakers off one power amp? Sorry for my stupidity, I Just have no experience with PA systems. Thanks!

It sounds like you need to learn quite a few things about PA systems. Here is a good guide on PA systems I found the other day:

Anyway, to shortly answer your question - yes, you need to put an amp between your unpowered mixer and passive speaker. Most amps are dual-channel, so you you won't need two of them. Just be sure to check the speakers' impedance (ohm number), RMS and peak wattage the speaker can handle, and find an amp providing the same wattage or slightly lower (that is the wattage at the speakers' impedance level).

Yes, you would just stick the power amp between the mixer and speaker.

Yes, one power amp can power two speakers. They typically have two separate amps within one power amp chassis. One goes to output 1 and/or left and the other goes to output two and/or right. Plug a speaker into each output. You can also set the amp to bridged and daisy chain your speakers together if their combined load is within the bridged setting's specs.

Let me know the wattage and ohms of your speakers and I could suggest a power amp, or just a range of wattage and configs you should be considering.

A used EQ would be another good investment right out of the gate. In short, it will allow you to get more output from the speakers before feedback
