The AC12 handles:

SpeakerLink --> SPDIF, COMMS & RS232 for a pair of DSPs.
........... <-- MASTER COMMS

I would like to see a couple of alternative small & simple boxes, one per speaker.

Master Version
SpeakerLink --> SPDIF, COMMS.
........... <-- MASTER COMMS

Slave Version
SpeakerLink --> SPDIF, COMMS

Nice & simple and installed either at DSP end or Process end to suit.

861V6 --SpeakerLink------------------> Box --SPDIF+comms--> DSP
OR
861V6 --SpeakerLink--> Box ------------------SPDIF+comms--> DSP

Regards
Carl
