Is my reciever coverting back to digital?


I have a Yamaha dsp-e492, it has no digital inputs, but it does have a sub-out, which sends out 120hz and below from all the inputs, except from the 6 channel discreet inputs. It has dolby pro logic processing available as well. Does this mean that the processor converts all signals into the digital domain, and then back to analog?
I know I shouldn't be using this thing as a stereo pre-amp anyway, but I'm wondering how much I'm really missing out on by not having, say the adcom gfp-750 or a similar ht bypass pre-amp in my system...

set-up:
yamaha dsp-e492 3-channel surround reciever
adcom gfa-2535 4-channel amp
monitor audio bronze b2 fronts and center (junk surrounds and sub)
philips dvd963sa

I bet, but do not know, that it is converting to digital and then back again...that's how it gets the prologic surround channels from 2 channel. My nice old, old lexicon processor converts to digital and then back. If and when I can afford it, I want a processor with digital in so that it does everything at once in the digital domain and there is no a/d conversion.
