Re: Speaker setup

Hey, I just picked up a pair of PA speakers at a yard sale for $20 for both. The brand is Toa. Unfortunately, they aren't powered, just an in and out jack. I connected one up to a stereo receiver, and it played the radio, but the other one has a messed up contact, the thin metal piece where the 1/4 jack goes is disconnected, (actually both the in and out socket are like that) and I need to fix them. I know the speaker works though.

Any suggestions? And all I'll need is an amp, correct?

Yep !

You´ll need an amp.

Check what impedance the and power rating the speakers have and buy an amp that is capable to drive them.

One thing to remember is that it is better to have an amp that is a bit more powerful than the speakers.

You could also look for a powered mixer.

I do have a mixer, it's a small Behringer unit. Probably not powered though, right?

Thanks

Nope, not likely.

What are the specs of the speakers ?

They say:

Cont. PGM. Input: 240 Watts
Impedance: 8(then an omega sign)

Ok,

ideally you would have an amp that outputs 300 W / 8 ohm ( omega sign ).

If you use an amp that is smaller/weaker you run the risk of damaging the speakers.

If you use an amp that is a lot more powerful than the speakers can handle you also run the risk of damaging the speakers.

Will do. I just wish I would have asked the guy if he had the amp that went with them.

Hey, If you go to a pawn shop I'm sure they will have a Amplifier for 100, or less. Look at peavy They are cheap, and durable I think they used 8 ohm speakers. I'm pretty sure, but check.
