OSD Audio 4 Zone Speaker Selector Switch Impedance Protection ISS4

Read some reviews stating that the contacts in the back of the unit, were of poor design/quality, but I cannot agree. I had no trouble at all tightening the contact screws, and the unit works flawlessly. Does everything i need it to do, and In fact, I was surprised at the build quality. I was expecting a plastic piece of junk, but rather got a heavy, metal unit, that works!

Works great

It does exactly what i had hoped. Works great. Lets me have sound in 4 different zones or all of them at the same time.

I was looking for a speaker selector at a cheap price for my very small starting business.I' m selling used speakers and receivers.It was evident that a selector was needed.I looked all over the web and this product was far ahead the others for is quality and price.I would certainly refer this product to anybody who need a speaker selector.

The unit feels rock solid and nice and heavy, it works great - the only negative are the very small inserts for the speaker wire, it becomes tedious to strip the wires down to the point where they can be fed into the clamps - and the screws that tighten them down are tiny. Otherwise the unit would be pretty much perfect. Assuming that you only have to go through the wiring process once, I'd say that it's not a big deal really.
