Maril, I'll do my best.
Do you mean my 11-29-03 post which says.....
"I am pretty sure the PCM D/A conversion is handled by the Motorola 56367 chip in this unit. It is SOTA for Multi-channel decoding but I think other dedicated DACs may be better at PCM. No problem though, just run Analog ICs and a digital input both. You can setup the input to "default" to the digital input(inboard DAC), Analog with DSP(outboard DAC), or bypassed(outboard DAC), then switch to whichever one you want, whenever you want at the press of a button."
When I say "PCM D/A conversion" I am talking about a digital signal. An Analog signal would have to be first converted to digital (A to D), before the DSP could process it.
It is my understanding, though I could very well be wrong, that the SP1.7 has only the 56367 Processor to concvert all incoming digital signals to analog, including PCM (two-channel 44.1khz/16bit which is the standard output from a CD player). In other words, I dont believe the SP1.7 has dedicated PCM DACs. Though an Email to James Tanner would clear this up.
I am not sure whether the 5.1 input is fully seperated from the Digital like the 2 channel bypass. At first I was assuming (dangerous indeed) that because there was Subwoofer control in 5.1 bypass that the signal must pass through the DSP engine. Thus, not "true analog." Faziod, and then James Tanner, enlightened me that indeed there was a "full analog" summed (full-range) signal output to the sub. So (assuming again), the signal path is present. Therefor it could be a "true analog" 6 channel preamp. Once again I am not sure and I bet James could clear this up right away.
I am sorry I dont believe this post was very helpful.
