Tech Talk:
The Ultramic uses the AD7685 (93.5dB SNR Grade C part)
Synchronization may require both firmware update of the uC and extra hardwa=
re support to dual converters in chain mode. Or a new converter like the AD=
1974 might be a better choice.
An audio solution would be to overlay e.g GPS clock as audio in the signal =
path of both mics and process accordingly. Talk to Lars Kinderman about tha=
t.
By how many samples (or even ms) have you observed in terms of drift betwee=
n the two line models?
For portable units, Ive actually not tested my MR2 at 192Khz I dont hold ou=
t much hope above 40Khz..
EMU Tracker pre was the closest I got to 192Khz on a computer and then real=
ized its drivers stop at 48Khz, the new Lion driver is out so Ill test that=
to 96Khz.
Currently playing with the Roland R26 which is surprisingly good for the pr=
ice, although that sadly doesn't solve your 192Khz requirement.
BR
Mike.
