My Velodyne V1012B amp just developed intermittent 60 cycle hum; maybe fatal for this old amp. I have an amplifier out of a VelodyneDLS 3750R. (1) Can I connect any wires in addition to the main red/black speaker leads from the 3750R? Signal processing? (2) without a remote for the 3750R is there any way to get it to reset to factory default (jazz) mode? TIA!
