Well, in addition to all mentioned earlier:
1. Can I use one DSP as a MASTER CONTROLLER for the rest of them w/o G or 8-series components? I worked a lot with Meridian equipment in my past, but some knowledge was gone with time. I assume that Meridian prefer to sell their pre/pro with speakers, but they definitely told me that it's possible to use couple of speakers with third-party digital device - like CD player. In this case couple os DSP's should be daisy chained with comms and coax SPDIF, and user can control volume with MSR. So - why I can't just increase of amount of speaker comms with 511 block?
2. To be honest all that "Meridian SPECIAL COMMS PROTOCOL BLA BLA BLA" is not more and not less than regular RS-485 based protocol. So, I have enough experience and client has enough money to add Crestron controller to the system. So, does anybody have idea of how that protocol works?

Thanks,
Oleg
