I've been making some changes in my house setup and have decided to sell the heart of my old system.

The MZA is a 4 zone 8 source distribution system. The 4 zones have both pre-outs and built in 50wpc amps. It is PC programmable and it can be controlled via PC (USB or RS232), IR (in and out) and RS-232.

It has a Party Mode to have all zones play the same source and an alarm function to start up at a preset time.

Here is a link to the Integra page to download the manuals and software: LINK

I will also include 2 Key pads. 1 Key 2.7 and 1 Key 5.7. These have both IR learning and will act as IR receiver to pass IR to the main unit for distribution to the sources. Single Cat 5 wire is all that is needed.

They Key pads are in link new condition and the MZA is consmetically in very good condition. There may be some minimal scratches on top from other sources sitting on top. The only functional issue is the the LED light on the front panel flickers when a zone is powered on. This was always out of site for me so it never bothered me and does not have anything to do with the functioning of the unit.

I will take pics tonight but for now here are stock photos:
