I need your guys help. I have a Marantz sr14ex. The marantz has six dig inputs. Anyone know how to hook up the denon 2900 to this or a similar marantz a/v? I went from the denon 5.1 outs to the marantz inputs and i can only get two channels. When I go to the 2900's channel levels I only get left and right front tones. I set the marantz too analog and still nothing. Im trying to use the analog so I can play super and sacd. thankyou in advance.
