Got an interesting fault on a Denon DN-650F pro CD player. The XLR outputs
are fine - but both the phono and headphone outlets topless - although
level seems normal. And all three are in parallel except for a 680 ohm
resistor in series with the lines to the phonos and headphone outlet. I'm
guessing it is something to do with the muting circuits - which seem to be
separate for each output pairs. A relay for the XLR ones, transistors
which short the lines for the phono, and a couple of op amps for the
headphone one. Talk about complicated. ;-)
