Sometimes the “professional sound company” was professional in the early 1980’s! This was the mixer that the sound company had for an event I was performing at recently.
You’ll notice that this mixer has no XLR inputs. Those are the standard inputs for microphones, so this was unusable by me. Of course the sound company didn’t have any adapters to get an XLR to 1/4. I think that this mixer is more for a guitar, than vocals.
So what did I do? I used their corded mic with a Microphone Holder and did the show with no music. Always having one of the Microphone Holders with my gear is frequently a life saver!
