The old Alice STM-8 was certainly one of my designs….. with a characteristic ‘paddle’ switch for the DJ mic.
Sadly, I don’t have a picture, although I will have another look over the next few days in my archives.
The STM-8 was a serious attempt to produce a low-cost but high performance broadcast mixer that would serve as a main desk for tiny radio stations. It was a success and we made probably about 150 of them.
If I come up with any pics I will post them here…….
