UMC-200 & Dolby Pro Logic IIz
The Emotiva UMC-200 seems to be a fine Pre/Pro in many ways. I would point out that the implementation of Dolby Pro Logic IIz is lacking, if not out of compliance with the Dolby spec.
To quote from:
Dolby Pro Logic IIz for Professionals
"Dolby® Pro Logic® IIz adds front height channels to surround sound, creating a 7.1 or 9.1 playback system for home music, movies, and video games
Enables increased flexibility for expanding a 5.1 playback system to a 7.1, or a 7.1 system to a 9.1"
The UMC-200 does not expand a 7.1 system to a 9.1 system instead it becomes a 5.1 system with height or as some would say a 7.1 system. The UMC-200 in Dolby IIz mode reconfigures it output so that the right and left front height channels now come out the outputs formally used as right and left rear. That is to say using the UMC-200 it is impossible to achieve a 9.1 system as called for in the Dolby specification.
While I have not examined all 7.1 Dolby Pro Logic IIz implementations, of the ones I have looked at none have chosen this method. In my limited sample all others have kept with the Dolby spec and allowed users to realize 9.1 outputs from 7.1 devices when operated in Pro Logic IIz mode.
Even given rear panel hardware limitations I believe that Emotiva could have easily chosen to have the height outputs reconfigure the Zone 2 outputs and replace Zone 2 outputs with height channel outputs allowing for compliance with Dolby IIz specified up-mixing of a 7.1 device to a 9.1 device.
Conjecture on my part
A possible reason for this choice on Emotivas’ part might be that their DSP ran out of power and can not realize a 9.1 system.
Flame retardant
Please note I am NOT addressing the pros and cons of Pro Logic IIz. I am simply calling attention what may be misleading statements on the part of Emotiva regarding their otherwise well reviewed UMC-200.
