Topic: Level Discrepancy Between FF 802 and ADI-8 DS
Hi,
I'm getting an approximately 8db level difference between my Fireface 802 and the ADI-8 DS connected via ADAT. I'll describe my setup and config and then a bit more about the issue.
Using ADI-8 for A/D only. A/D section connected via Toslink cable to ADAT input 1 of FF 802
ADI-8 is master, FF set to slave via ADAT1
Clocked at 48,000 khz with clear audio so no evidence of sync issues
Level of ADI-8 A/D section set to +4dBu
All line inputs of FF 802 set to +4dBu
All levels in TotalMix set to 0.0 db
Given those settings, I would expect the exact same volume from the line inputs of the FF and those of the ADI, but the ADI-8 inputs are about 8db louder than the FF line inputs. I connect my Juno 106 synth directly to a pair of inputs on the FF and peak around -20 db. Using my patchbay, I route the Juno over to the ADI-8 and peak at around -12 db, and I cannot figure out what is causing the increase. I've tried all conbinations of both balanced and unbalanced cables, all with the same 8db difference.
Any ideas?
