Re: Denon AVR-x4200w calibration with REW and Umix-1

Dear AudioCraver and John,

thanks for share your personal experience here looks like that a miniDSP product is the right choice, but which?
FYI, 8 channels are enough

the nanoAVR DL sample at 48kHz, has got dirac live but only HDMI
the nanoAVR HDA has got analog output but it needs 300USD to be upgraded to DL, and still the filter will sample at 48kHz

now let's agree that 96kHz or more have not substantial audible benefits vs 48kHz, but looks like that the HDA has a more capable processor ready in the future for an eventual filter upgrade (my assumption and opinion here)
I would have the nano after the AV, so the Denon will decode every inputs and send the PCM to the nano. As chain, I would have something like that, but I have no idea if technically is possible

option1
all inputs --> AV --> AV HDMI output1 --> tv, output2 --> nano --> analog output --> speakers (or back to the AV as pre-amp signal and sent to the speaker after)
(could it work? will I have any delay in the video/audio sync?)

option2
all inputs --> AV --> AV HDMI ouput1 --> nano --> nano HDMI out --> AV --> pre-amp to speaker, HDMI to TV
(I don't think is possible but this will be the best solution)

note: the TV is the netflix hub, so that input should be sent to the speaker filtered as well
note 2: if I send the PCM signal from the AV, am I going to lose all the decoding benefits?

as far as I understand, the nano must be put between a device and the AV, but IMHO this have some limitations
- need one nano per device (TV, BD, PC, apple TV, etc.)
- use a cheap BD or others as compressed sound decoder instead of the Denon, so it's a kind of "waste" of resource...

how did you connect your system?

thanks!

cheers

Re: Denon AVR-x4200w calibration with REW and Umix-1

This is where the "limitations" I mentioned come in.

Not positive that the AVRHDA is upgradable to Dirac.

Do you have powered speakers? They would be needed to connect to the analog outputs of AVRHDA which are 2V max.

Connecting to pre-amp in on AVR (last part of option 1) won't work.

What may work is an hdmi switch before AVRDL so that signal chain becomes ALL INPUTS => HDMI SWITCH => AVRDL => DENON. I say "may" because of the limitation of providing LPCM (or more specifically MULTICHANNEL LPCM) to the AVRDL and because I'm really not up to speed on how the TV operating as your Netflix hub works.

For myself its BD player to NANOAVRDL to Receiver. Simple and mostly works without incident. BD player also has Tidal, Vudu and Netflix streaming that I use. DirecTV genii will NOT decode dolby and output MULTICHANNEL lpcm. I have a way to make TV work but don't bother.

And now its time for the opinion portion of this post... My primary reason for Dirac is 2 channel because it produces the best imaging I've been able to obtain and its MUCH better. It also significantly improves the sound quality of the bass on music in my setup. Same for multichannel audio. For movie use its still doing its job but I'm not as particular and would not have bought it for movie use vs YPAO or Audyssey. For movie use I would prioritize dual subs for anyone not already having them because dual subs will also smooth out bass SPL, help with seat to seat differences and get the always welcome additional headroom for movies. (Sorry for going off topic there.)

John,

thanks for your suggestions!

So the only way to get the system works looks like add the DDRC-88A, using the pre-out analog straight to the speakers (they are active), but it costs 1k.... definitely out of budget
is there any other EQ more than the MiniDSP?
I'm old enough to remember that old receivers had the EQ I/O, but it's not the case anymore...
I'll try the dirac live demo as you suggested and let you know my opinion, based on the measurements and listening feedback

cheers

Unless you like it enough to develop a case of upgradeitis!
Agree with your set up the 88A or 88A-BM would be the best choice. I believe Ellis on this forum uses two of them for his atmos set up. He and AudioCraver are both very knowledgeable if you ever go that route and need a hand.

Sadly, me too. I'd wager minidsp and dirac would love to see a digital multichannel "tape monitor" type circuit.

Look forward to hearing what you think.
