No doubt the output channel board has been brought in, in preparation fro Auro3D, so whilst someone that has 7.4 traditional channels, and wishes to add 5 Auro3D height channels, take the count to 12.4, if they wish to add Neo:X width channels or bi-amp any channels (using the RS20i as an active crossover that is) they're already over the 16 channels currently available. In truth though, as you say, few people will need that many.
That is, unless Datasat add simultaneous multi-room functionality. I'd don't even know if its technically feasible on the RS20i, but if it was and did become available, then additional channels would most definitely be required to feed additional zones - personally I am already thinking of using two channels on the RS20i for an additional stereo set-up in another room.
I agree though, more input channels are required. Four HDMI inputs is somewhat lacking at this level, as is only one active output. Some 'official' way to utilise the DB25 digital inputs for additional coax or stereo AES/EBU would be useful also.
As I've said before also, a simple IR or RF remote control could be added with any new board, and would take the pain out of the VNC interface for rapid volume control.
Yes, I agree that additional output channels are for the Auro 3D program but the availability is still away off and the requirements for a richer input selection is now.
It sounds that we have similar requirements I to need AES, extra COAX inputs, a second zone and better volume controls. All to some degree I have managed to overcome but not at the same time and with certain limitations.
An Extra AES input is possible using the digital inputs but it is restricted to one only per 8 channels.
Each DB25 connector is wired to the Dolby DMA8 standard and is connected as 8 individual channels, not inputs, which means that if you use a DB25 to AES/EBU snake cable you only have 4 AES/EBU conectors (2 channels per connector). If you use both DB25's then you have a total of 8 AES/EBU.
Unfortunately only one pair per DB25 can be used as a standard digital input which is the first pair on each connector (1,2 and 9,10) and the decoder can be configured to accept the necessary DTS or Dolby surround input.
The reason you can’t go to any but the first input pair is you need a master clock for each pair and that is only connected to the first pair.
It is possible to add a second zone a solution is, set the RS20i output mapping channel so that each output has channels 1-8? So instead of having channels 1 - 8 and 9 - 16 you would have 1-8, 1-8. Also to note that any zone type arrangements will have the same EQ settings.
If just a second 2 ch area playing by itself is required then via one of the presets with the output for it sent to other amp channels driving those speakers should work.
I have also added a third zone rack monitor by using the monitor output, this is only mono but fine for a rack monitor.
I have created my own volume controls using AMX, as part of my overall control of RS20i, so I have direct control of both the main and the monitor both at variable speeds.
