This review is from: 70V 200W High Power Line Matching Transformer (Electronics)
I'm not an electrician. I just want to hook up my 200W Sony stereo receiver to my office's speaker system. There are about a dozen speakers installed in different rooms. Each speaker has its own in-wall volume control with a small transformer attached to it.There are only 4 wires that come out of the wall, available to hook up with my receiver/amplifier. Evereything worked fine until last month, when burglars broke in and stole my receiver and some electronic gizmo that looks like the picture of this product. I have managed to figure out that it used as a 70-volt system, with down-converting transformers at each speaker. I tried hooking up this transformer between the speaker outputs of the amplifier and the 4 wires that come out of the wayy, but it doesn't work. I have tried every variation that I can think of. Since there isn't any documentation or instructioons with this product, I don't know what to try next! HELP!
