connect 901 equalizer to Marantz SR19
I am having trouble connecting my equalizer to my SR19. It worked and then I disconnected everything to have the receiver repaired. Did not map connections. I have preamp out, in and main amp out, in and then two jumpers. Suggestions for how to connect and do I still use the jumpers? I have tried various combinations and even tried the tape in tape out which gave me sound but no response from the equalizer. I am wondering if the equalizer needs repair. I followed instructions in the Bose manual but I can get no sound at all using the preamp and amp connections. Any help is appreciated. Dumb questions I know but I need help. Thank you.
