Is it possible to connect a Dolby DA20 to a Smart MOD7 without any special adapters? All I should need is custom cables?
Monday we are getting another Barco. I wanted to take the CAT700 reader and DA20 off of the projector its replacing and install it on one of our Analog houses. [Big Grin]

Okay, I have this mostly figured out. Audio connections from the DA20 to the MOD7 is a no-brainer. But what about the automation? Obviously it should be in auto-digital. but which type should I use, and which control lines should I use for the MOD7?
Pardon my ignorance, this is the first time I've connected anything Dolby to a smart processor.

Hello Christopher, i try to connect a Smart Mod 7 to a DA 20 and can't make that the auto Analog/Digital works, only will use manually, maybe wrong conection, don't know.

Martin, I'll be doing a test-run tonight. If it all works as it should I'll post on here how I wired it up to help you out. [thumbsup]

Alright, The test was a success [:

Martin, the Wiring I have is as follows

MOD7 DA20
Digital Pin 12 - SRD pin 5
SR Pin 13 - SR Pin 3
Logic ground Pin 25 - GND Pin 12

And I'm running the DA20 in the CP65 Auto-Digital(position B I believe)

Problem is what will the Mod 8 do with all of the good sound? Perhaps we should consider it a bottleneck like installing an orfice in a plumbing pipe. Louis

I'll second, third, forth and fifth what Louis says.
