So about the digi-in....is there a sort of threshold (don't know what else to call it) that allows the digital signal to be attenuated or bumped up? Or is it just dependent on the levels the pre/ADC is sending out? i.e. it the levels are automatic and there isn't any way to adjusted the incoming digital signal on the MT?
if the spdif signal is bit transparent there is no way to adjust the gain digital in on the MT.
i used to own a creative soundblaster sound card(a known non-bit transparent card) and could adjust the gain digi in with the creative software because that card sends the signal through a DA>analog stage(where you can add the gain)>back into the AD(whre it resamples).
if you can adjust the volume of the spdif signal on the MT, i'd have to believe that it is not bit transparant and sends the signal through an analog stage first.....which would suck!
