Topic: ADAT Sync ? with 2x Digiface & 3x Midas DL16 Stageboxes
I am testing ADAT Sync between a pair of Digiface/pcie and 3 Midas DL16 Stageboxes.
I have assigned the 2 adat output pairs of each dl16 (ch 1-8 and ch 9-16 on each unit for a total of 48 channels) to the pair of Digifaces - with the 2nd dl16 split between the 1st and 2nd Digiface units). The 2 Digifaces are sync'd with WC.
So far, I've been able to test record a single microphone source split at the physical inputs to channel one of all 3 DL16s for upwards of 1.5 hours, (apparently) without any drift whatsoever. However, I am seeing at least one adat channel light of each Digiface blink on/off on a regular basis (roughly 20-26 second intervals) and this has me concerned.
I've never relied on adat to sync multiple preamps before - always having used word clock. But I have to, since the Midas has no wc and only adat out (no adat in). Can someone tell me/assure me if this is normal behavior when syncing via adat?
Is there some other way I should be hooking this all up to be assured of sync for hour to 2 hour long recordings of upwards of 48 tracks in a live concert setting? These Midas units are replacing my 16-20 year old Presonus preamps and I can't afford to invest another 2-3k replacing the pcie interfaces as well at this time.
