No I didn't mean that, I was just saying that some dacs have adc as well as dac conversion.. I think Evshrug has said that they won't be any sound with a dac to a mix amp combo anyway, but thanks for taking the time axel!
That's not what I was saying, let me try again to clarify:
A typical DAC can only convert a stereo signal to stereo analogue. So if a console sends DDL 5.1 to a Bifrost,
you're gonna have a bad time.
A Mixamp will take a digital surround signal (Dolby Digital Live 5.1, which is actually a bit compressed to fit in the bandwidth of an optical cable), use a
DSP (Digital Signal Processor) to convert that
DDL signal to a stereo signal specially processed with
DH (Dolby Headphone) to sound
like a 5.1 speaker setup, then the Mixamp uses it's
DAC (Digital to Analogue Converter) to convert the stereo specially mixed with
DH into stereo analogue, and then amps it (a bit) so the user can control volume.
Actually I think Hedonism was wanting both to play together. Chicolom owns
this puppy and I recall him saying that it can have multiple sources active simultaneously, allowing for a mix of the two/three/four. Downside is that it's RCA and 1/8" only, so you'll need to have the right connections for it.
Thanks for finding that, I forgot what it was called or where it could be bought.
Incidentally, both the Mixamp and DSS have auxiliary stereo 3.5mm inputs, designed to allow gamers to play music while gaming, but you could feasibly add any stereo analogue audio to the "mix." That doesn't solve Stillhart's puzzle (the accessory you linked does), but just sharing for everyone's info
[so, just to confuse Martin Vegas since there would be no point in doing this, with a Mixamp's aux analogue input you technically could connect a bifrost's analogue output to the Mixamp, but you wouldn't want to because the audio quality would be cut down to the Mixamp's quality level.
