SPDIF I/O's

[horsegrip]

Are the SPDIF's outputs 24bit?
And how do you change the sample rate from 44.1 to 48khz?
Also, can the TI act as a slave to a Master Clock sample rate through SPDIF?
Cheers guys

I have never seen an authoritative answer to this. I did an experiment just last week in which I tracked a half-dozen parts via S/PDIF, and examined the bit depth using a utility that I wrote myself. I found that all 24 bits of the audio I captured were in use. I was quite surprised by this. It should be taken with a grain of salt as I haven't heard anything from anyone else on this. There is a post on this forum according to which Access tech support says all the digital audio outs operate at 16 bits. That it not what I see when I look at the bit streams coming out of the unit however. Dunno what to think.

In the CONFIG menu's global parameters, there is a clock rate setting.

Yes, if you set the clock source to Auto (CONFIG menus again) it will lock to the incoming S/PDIF clock. It burps sometimes on patch changes and mode changes, or at least it used to. I find it to be steadier and more reliable to derive the master clock from the Virus's S/PDIF output instead, but both things can be made to work.
