We had one of these at Don Wehr’s Music City as our keyboard demo controller. The noise gate worked fairly well, as long as you didn’t overdo it. It also had an onboard spring reverb. Strangely, it was a monophonic mixer, but it had two XLR main outputs on the back that were simply the same mono mix. It did however make it easy to feed a stereo power amp directly (bridge/parallel switches on power amps were not very common in the 70s.)
