CPS III Volume question

Every time I hook up my CPS III board to the Q sound amp in my Impress cab the sound is ungodly loud. The volume control in the cab is only for mono audio. I have heard there is volume control located on the board, but I can’t find any info on it. Any help is greatly appreciated.

There is only one potentiometer on the board, shouldn’t be possible to miss…

Just saw it . . . wow . . . couldn’t have been any more obvious LOL :bgrin: Thanks man
