Not sure if this is the place for this, but I hope you guys can point me in the right direction.



My wife runs auction/bingo events in an old retail store every month.  They use a freestanding PA box but want to try to use the store's speakers (ceiling mounted) to call out their numbers/winners.



I found where the speaker wires terminate with simple speaker connection (2-wire) in the back room, but don't know what to get her to hook up to that connection?



I want to get something that's pretty inexpensive and all it needs is a microphone input and simple speaker output.  I figure it will need an amplifier in it, but don't know what to search for.  I could just pick up an old boom-box and plug a microphone into it, but that's pretty ghetto.  What's the right way to hook into this old Muzak system's remnants?



Thoughts? Direction?



Much appreciated!

Probably a 70 volt system

More info and pic would help..

If you can get a  look at the speakers, see if they have a small transformer on the  speaker frame. That would indicate strongly the set up is a 70 volt rig.

Doable, just some leg work involved.

It's a 70 volt system with a transformer mounted to the speaker.  The transformer is also marked 8 ohm.  



The system is completely wired all the way to the back room where it looks like the previous tenant simply cut the wires at the wall when they left.  There's plenty of wire to work with.  



I was looking at this system:

or something like it as we don't need to go high end or super fancy.

You are good to go..

Hook up that amp in the link and be ready to ro......

Ok.. no stadium rattling volume, but it'll get the job done.    It'll be lo-fi.
