Audyssey Processing, Analogue or Digital?

Hi Chris

Have asked the question elsewhere but i'll go again here.

Is Audyssey processing (MultEQ XT equaliser and Dynamic EQ) applied to an analogue signal path as it's received from a CD player via analogue inputs? (D/A conversion in player)
or is my audio being re-sampled (A/D), processed by Audyssey and then converted back to analogue in the AVR by the DAC's in the AVR? 

Have more questions? Submit a request

    Hi Rob,

    No processing of any kind is possible on analog signals.  They must be converted to digital if they come in as analog.  This includes Audyssey, bass management and every other process in the AVR.

    Thanks

    I may aswell re-configure my system to run CD audio (when not using pure direct) via HDMI or Denon-Link as it's just adding extra conversion steps.

    Cheers

    Actually,

    Chris, can you confirm where exactly in the processing chain does Audyssey apply it's corrections. On a Denon AVR2809 with MultEQ XT

    and is it 100% software based, or does it have it's on on-board D/A, A/D converters for re-sampling and re-encoding?

    I know some of this may be bordering on proprietary knowledge, etc

    Just looking to keep my connections as simple as possible, while getting teh best sound that i can

    and just interested in how/ where in the signal chain it actually works.

    I.e does it re-route my analogue audio back through the Denon A/D converter or Audyssey's own A/D, then pump it back out through the Denon D/A (or Audyssey D/A) 

    Sorry to complicate things, i'd just prefer to keep conversion to a minimum if possible and use the best DAC's i have at my disposal

    Cheers

    Hi Rob,

    Audyssey algorithms are software that run inside the existing chips in AVRs.  Audyssey doesn't have anything to do with A/D or D/A conversion.  It will process any signal that the AVR maker sends to it.

    Frankly, the effects of A/D and D/A conversions are greatly exaggerated by the audiophile press.  In today's products, these are not really audible.  There are much bigger problems to solve that affect sound quality: for example, room acoustics!
