the cat visconti channel is almost gasp. complete.  just waiting now for a final bit of metal worked rear ass covering solution . sounding perfect . it’s made to be a best quality mono recording channel with mic/di/line stages and 4 way eq and filters with processor insertabilty. the output of that can mix (or not) with two stereo line inputs. the listenator function runs either the alone channel or the mixture of the alone channel with the stereo inputs –  into one of two selected pairs of speakers.  alla fenkner functionality.
