Disklavier

The phono connectors on the back of the DKC55RCD are inputs. If the unit detects an analogue MIDI signal on one of the channels, it will convert both channels to digital data and split the channels into it's MIDI and audio components and send the MIDI part to control the piano and the audio part to both channels of the headphone/AUX OUT connections.
The CD Control connector (and the 15-pin D-type connector) only transmits/receives power and digital data. There is no analogue audio signal which could be used to send to an amplifier or powered speaker. The only point at which an audio signal can realistically be tapped into is the headphone box on the piano. Occasionally, dealers have had the DKC units stolen from their shop floor pianos. Unless the thieves have a matching Disklavier, the unit is completely useless to them and cannot be used to listen to audio or MIDI files.

BTW the DU1A is a Disklavier Mark III. The E3 version is the DU1E3
