Hi t42,

Don't forget to allow for a system where the Master DSP is also the controller.
This means you need both comms in and comms out from the DSP; it is not an either or situation.

Star wiring; Meridian processors with SpeakerLink outputs have 4 RJ45 pairs (8 RJ45 ports) so you don't have to worry about 1 source driving two Cat5s it is already done in the processor.

Hope this helps.

Regards,
Carl
