Indeed your right, ADAT is a real step down in and out of the o2R unless your using the TC Unity which is supposed to provide 24 bit with the ADAT and TDIF connector.
Or unless you halve your channel count and activate the 24bit recording mode, I've no idea how this works apart from Yamaha splitting the signal up and recombining it at the other end, how that works i have no idea whatsoever. It certainly doesn't work for me, i end up with the loose extra BITs on two separate channels coming out as whitenoise
However been doing some investigating with all this tonight..
I believe the convertor will convert like for like BITs, so if 24 bit is coming from the TDIF card then 24 bit will pass through the ADAT optical.
I think ADAT is where the blurred lines come, because looking at the TDIF situation
i seem to be getting 24bit in and out through it without any audio artifacts
and the quality of the signal looks to be bonafide 24bit in steinberg wavelab, this appears to be working by making sure your NOT in 24 bit recording mode, but i might be mistaken, what i do know is the sound quality sounds really good when the 24bit recording mode is off via TDIF.
Im thinking at this stage the splitting the ADAT channel in two to achieve 24 bit over light pipe might just be for ADAT optical, whereas the TDIF appears to be operating in 24bit to and from the o2r at the correct rate regardless of the recording mode setting.
I would love some verification with this though.
