ok i know this may be a strange question (hopefully in the right forum)- If someone buys Yamaha passive pro PA speakers from light Guitar Center- Can those be plugged into a Home theater type receiver? Our school music teacher has an older 200 Onkyo receiver/amp like you would have in your living room.... someone donated a pair of Yamaha passive speakers (I think they are like C112V model speakers-)- Will this work? I've never combined home-model amps with pro audio speakers- Pros and cons??
Sure it will work, a speaker is a speaker. A home receiver won't have anywhere near enough power for that speaker so you will have to be very careful how loud you turn the volume up.
Insufficient power will destroy a speaker quicker than too much. It's not intuitive but when an amplifier is asked to do too much it does what we is called "clipping". These type of signals will damage the speakers.
Make sure you hook them up the same way. Observe the positive and the negative. If the speakers have a connector that looks like a guitar plug the tip is the positive. If you reverse one side the speakers will cancel each other out. You will have to make your own cables unless they gave you some. In that case you will have to cut one end off and connect it to the terminals on the receiver.
Lastly, this is the wrong forum for this question. I am sure a moderator will move it, it needs to be in the lounge.
