I want to play a video with Dolby 5.1 audio. Where does the Binloop output digital audio?

The digital audio outputs are available on the connector labeled AES/EBU.  Each reproducer has a (-) and a (+) output on this connector.  When wiring to a standard RCA coax digital audio cable, the (-) should be wired to the shield and the (+) should be wired to the tip.  When playing a video with 2-channel MPEG audio, this output generates a S/PDIF signal.  When playing a video with Dolby Digital Audio, the analog outputs of the Binloop are silent and this connector outputs an AC3 signal that must be fed to a Dolby Digital decoder/receiver.
