My RMC-1 runs extremely cool. I see no need for any type of special ventilation for it. What type of space are you thinking of putting it in? Thank you. Mine is just a custom-made stack of wooden shelves, placed in a corner of the room (it's a living room, so I have no, er, wiggle room). Even a class A amp would be fine there, as long as there's enough space above it. So that's what I need to plan: distance between RMC's top and the shelve above it.

The processors draw a little less than 40 Watts so not much heat generated, I’d want at least a small space for it to breath, but it shouldn’t need much.

I didn’t say it was. How did you come to that conclusion from my post? When you said, "XMC-1 sounds great without and PEQ" I took that to mean you didn't think that PEQ was necessary for the processor. Not necessarily what you meant, but I read it as if you were tying the sound of the XMC-2 to the need (or lack there of) for PEQ. If you said, "My room sounds great without PEQ" I would have interpreted it the way you meant, perhaps? My room sounds and measures great without PEQ so I use the RMC-1 in direct mode. However, I will try Dirac when released but am most interested in Dirac Bass Control (DBC) to spread some bass among the 4 Revel Salon2s. - Rich

Does anyone know if the DAC used for Zone 2 is also an AKM4490? I did not this info in the manual

Does anyone know if the DAC used for Zone 2 is also an AKM4490? I did not this info in the manual Per the RMC-1 product page... " Audiophile grade AKM4490 Verita DACs, operating in fully balanced Mono mode, on all 16 Main Zone outputs. (Independent AKM4490 DAC for Zone 2.)" I would assume this is the same (with the exception of the "main" zone DAC configuration) for the XMC-2...

I rechecked the Xmc 2 manual and still did not find the same statement regarding DAC for zone 2. I am wondering if they kept the same DAC quality or downgrade it to reduce the overall cost....Since I am envisaging to use the Zone 2 output extensively for outdoor listening I would like to know which quality I could expect...

The Zone 2 DAC is the same for both....
And, just to be clear, that DAC, even in its "regular stereo differential mode" is really really good. (Unless your outdoor speakers are better than most of your friends' indoor speakers then don't worry about it... )

I think that the Zone 2 outputs are RCA, right? Not XLR? The cables behind my preprocessor are as neat as possible (to length, etc.), but there’s no getting around them laying on top of each other — including Power Cables ...

My question I guess is.. how many DAC are in the RMC-1?

I have had my RMC1 L for only a few days and can't seem to get the FireStick 4k work properly with it. The video cuts out frequently for several seconds but the audio remains uninterrupted. I also have a Roku ultra which works as it should. The FireStick 4k worked fine with my previous Yamaha receiver. Any ideas on this would be appreciated.

Thank you. I haven't had electrical theory in almost 30 years so I'm fuzzy about differential and single ended. And do people sometimes refer to differential and balanced as the same thing?

Yes they do ; the nomenclature is all over the place ; emo likes the term "quad differential" for some of their power amps. The nice thing is that when Emo says it uses "dual mono' on a channel with the AKM dac in this mode the whole circuit input to output dac;volume control and output stage is truly balanced. Other brands use single ended circuitry converted to dual differential as its cheaper without duplicating circuitry The last Denon for example that had fully balanced circuitry in/to/out was the AVPA1HD ; 1 reason for its cost

I remember differential being the voltage difference between positive and negative but I didn't understand how that relates to balanced. Those are two different things I assume. I assume I'm way off topic now, I'm still wondering what about a differential DAC is better than single ended? Is it just the noise cancelation?

I assume I'm way off topic now, I'm still wondering what about a differential DAC is better than single ended? Is it just the noise cancelation? If you look only at the common mode noise reduction its only about 3db better s/n ratio and dacs these days are 120db or more down , Heres a good article that shows how it depends; hometheaterhifi.com/editorial/oped/are-dacs-with-lower-s-n-ratios-indistinguishable-from-those-with-higher-ones/Its been mentioned that a complete system of balanced components has symbiotic advantages when combined . I like to think anything that rejects rf and smps noise like common mode rejection and balanced circuitry is good in a cramped chassis like a pre pro or avr Needless to say what comes after the DAC is an important bottleneck too ; cheap digital volume controls cant compare to a good analogue ladder volume control like Emo uses ;watch the s/n go south with digital attenuation www.thewelltemperedcomputer.com/Intro/SQ/VolumeControl.htm

My theater is absolutely silent without a signal present and my living room has an audible noise floor with no signal present. Both have XPA Gen3 amps and all sorts of power, Ethernet and signal wiring draped down the backs of the racks. I'm a believer in fully balanced!

I also use balanced everything, besides my subs for miniDSP purpose, with my RMC and XPA gear. No noise at all. But I never had noise using bluejean cable RCA and Denon avr as a prepro prior to this either. I think part of that is attributed to the Emotiva CMX-2's I'm using also.
