The Samson S-Zone 4 channel/4 zone mixer is designed for a multi-zone installation such as in a restaurant, bar, hotel, business, etc. This one was purchased as part of a bulk buy from an AV Company that went out of business, and apparently had been pulled from a restaurant/bar that closed a few years ago.

Testing consisted of plugging in power, turning it on, punching every button and turning every knob. The lights lit and everything felt fine, but we didn't wire up any speakers to it nor plug in anything to an input. We presume it was working in the restaurant/bar to their satisfaction. The one noticeable problem is that the Zone 4 button on Input Channel 1 doesn't release easily - you have to pull it or wait for it to come out. But it still lights up when pressed in. (It was pressed in when we opened the box.)
