[BC] mix minus for codecs

[Oradat, Chris]

Comrex has a device that will take one input (AUD from console) and generate a mix minus for up to six devices.  Talk back can be done by either pressing the corresponding button on the front, or via remote.  I've used a previous generation of this device, and while to connections weren't exactly clear (what is with mix minus), it worked beautifully.

I am taking the 'Studio' feed out of them and feeding the codec(s) as to 
best utilize the 'talkback' function, etc.
This setup works great... for 'off air' monitoring, conversations 
between remote/studio, and cues. :-)
Where it doesn't work well, is last night... when the studio operator 
would not only cue the talent via the 'remote' feed of the codec, but 
also wanted to comment/converse with the field reporter, etc.  So... we 
had a need to keep the 'remote' feed up along with the 'local' feed... 
problem is the 'remote' feed was delayed, and included him.
So what we had was massive need for a separate mix-minus.
