Hi,

I have 2 AV32R (96 and 192khz version), both without TMREQ.
Is it worth to connect the 5.1 to a Stand-alone version of the Audyssey Sound Equalizer?

MultEQ Pro User Guide for Audysses Sound Equalizer

Maybe this quite recent room equalizer with 8 channels is even more powerful than TMREQ.
The only thing I think about, the input level of a volume-controlled pre-amp is not fixed and quite low. for this kind of processor. But the installer guide even says that it should only be connected to pre-amps and not highlevel 2V RMS.

I would guess that it could be better work with fixed levels to use the whole range of the input ADCs, but fixed level loops are not available from most AV preamps such as the AV32R.

And then for the Audyssey I'm not sure if it is possible to do the equalization on my own or if the software is even available. For the TMREQ we have the guide here how to do it yourself.

I also thought about involving an Audiodata Audiovolver.

I'm note quite sure about the analog section of this small linux computer, but the plan would be to use it digitally only. So the digital devices would be connected to the Audiovolver, the AV32R would still work as DAC behind the Audiovolver due to its high quality analog circuits.
For analog devices I would try to use the ADC of the AV32R and use the Audiovolver in a digital loop for the AV32R. But here I'm not sure if the Digital in/Out of the AV32R may work as a digital "Tape loop", so analog input converted to the AV32R digital out, while listening to another digital input. I don't think so. If so this would achieve the highest quality I guess, to be able to hook up into the digital signal of the AV32R. For digital sources it is not the matter, the AV32R would just be linked to the already equalized Audiovolvers digital out.

Then I think about dropping one AV32R and finally look for a TMREQ version, but these are still expensive on the market...

About the question how to configure that unit myself I got the information:
There is the installer kit available, together with Windows .NET application, USB-interface, a calibrated microphone. Then for calibration of one unit there is a registration key to be purchased.

Or one can call a local specialiced service capable to do the configuration. But then you are not able to change the room installation without reconfiguration.

I'm definitly interested in the Audyssey stand-alone solution, eventhough don't feel comfortable to re-convert the analog pr-amp signal of the AV32R back to digital domain and back again to analogue, while the TMREQ can doo all this in the digital domain only. Maybe with that high resolution and that many filters of the Audyssey this is not a matter.

The idea of inserting a digital-only processor for analogue sources is not possible due to the following part of the AV32R documentation:

It is not possible to route an analog source to the digital coaxial outputs.
