I pulled it out of a home where it was working, although frankly I did not check all six zones. There are keypads which I think may be called K-2. The amp is 12 channels at 30 watts each. I hate to just recycle it. However it would be a pain to ship. If somebody in the Northern California area would like to pick it up, it is all yours. If someone wants it shipped, you will have to pay for a couple hours of my time plus shipping.
