fixed.
Thanks.
By "ruined", do you just mean it's noisy? Because while I hear plenty of noise, I don't hear any overload or distortion.
If you had recorded on Low and bumped up the level in post to match, it would have been at least that noisy, if not more so. It seems that the problem was very low input levels from your mics, not anything with the High gain setting on the 680.
This was AKG CK 63 > Naiant coupling/PFA > (adapters) > 680 mic in, gain on high, trim pretty high, I want to say like over 20. I will say however, that I was running to channels 5/6, 1/4" in with XLR > TS 1/4" adapters. Not sure if that affected it. Someone mentioned the unbalanced signal might have been the culprit?
I don't understand this. How could you have been using phantom power adapters with a 1/4" TS adapter? The TS plug would have shorted out the +48V between the sleeve and ring.
As far as my clip goes, I remembered that I had already recorded one:
https://dl.dropboxusercontent.com/s/qdjam3wyepnup4e/SM57_st.flacSM 57 -> ART SplitCom Pro -> DR-680 ->
channel 1: Low gain, Trim set to +23 (mixed left)
channel 2: High gain, Trim set to 0 (mixed right)
Note that the signal level is equal on both tracks, but there's significantly more hiss on channel 1.
