A couple of questions to help clarify things for me.
-Are the "Direct Mode" and "All stereo" modes, assuming that HDMI is the input, different in that if in Direct Mode the original signal is put through while the All Stereo mode will apply additional processing to derive a channel that is absent, for example lets say a 2.1 signal will output a 5.1?
And I saw a diagram/graph on the output signals and read that there is a flaw in a few outputs but I couldn't really understand it since the only obvious flaws, that I could see, were the Headphones output and "All Stereo, Mode, 2 Channel Analog/PCM input" but both "Direct Modes PCM" were listed.
I was also wondering if anyone was using a receiver/amp with it's own volume control. I am thinking of puting the UMC volume at halfway and just using my receivers volume control. I would appreciate any thoughts on this.
Thanks in advance
all stereo, as others have said, should be called 'all channel'.
--if you send a multichannel pcm (5.1 via hdmi from a ps3, let's say), the umc will lock onto "all stereo", which in fact it's truly a 5.1/correct decode you're hearing.
--if you send a stereo pcm signal, stereo mode will indeed play stereo. "all stereo" will spread the signal around to all speakers-similar to 5 channel stereo on some other receivers.
--xbox via hdmi sending dolby digital makes the umc say 'dolby digital'- weird because it NEVER says that for the ps3 regardless of what mode i'm in;bitstream or multipcm.
i though there was a problem with the ps3, because i have seen the words 'dolby digital' on the umc before. it even says dolby digital for the sat box (fed optical-trust me, it's just easier)
direct mode, IICR, is intended for stereo sources (although you lose bass management. with stereo mode, you get eq changes and bass management), and i'm not sure how the receiver behaves, or if you can even switch to direct with multichannel sources.
about your question regarding the umc "in the middle", i'm not exactly sure what you'd be gaining with that kind of setup. it may do more harm than good. introducing yet another prepro or av receiver will add another round of potential sound colorations/characteristics that may not be favorable. trying to figure out the volume on the umc to mimic a continuos signal flow is like trying to figure out how loud to turn up an ipod running into a stereo through the ipods headphone outputs, because there is no 'line out'. it's just not the right way to do it, but i guess it "works" in the end. i'm sure eventually you'd get some sound
