For most if not all AVRs digital signals always pass though the DSP, the DACs and a digitally-controlled analog volume control.
Audyssey (MCACC, or YPAO or other system optimization software) runs as a task on the DSP, along with Dolby and other AVR-specific firmware.
If you want to figure out what the DSP does, check out your user manual and see what functions disappear in bypass or analog direct mode. They will usually include audio decoding, system optimization, and bass management.
I see that someone has questioned my discussion of digital functions in a discussion of amplifier power. I justify this because in most modern mainstream AVRs, the end user has no access to the direct power amp inputs, or to a lesser extent the outputs of the signal processing in the AVR. From an end user viewpoint the power amp could process analog or digital signals and AVR usage would remain the same. Right now we have no true digital power amps, but down the road we probably will and the basic functions of AVRs could easily remain the same.Edited by arnyk@pcavtech - 8/11/13 at 5:22am
