How do I hook up a Denon DN-770R dual cassette player (with TWO lines out; one for each deck) to a Denon receiver/amp (545?)
The receiver has only ONE PB input. Is there a "split" that can connect both A & B outputs - or some other method of sending signals from two into ONE input?
Pictures online show the Denon 545R has tape 1 and tape 2/VCR playback and record outputs.
The cassette deck has a set of record (input) and play (output) for one deck but only play (output) for the other.
You can connect that second output to any input but phono if your don't see tape 2/VCR. No loss since that side of the deck is play only,
