I’ll try to set on mono. Thanks for the tip Tim.
On the UMP you can set the audio inputs to:
a) CH1 -> XLR 1 Mic | CH2 -> XLR 1 Mic Backup <- does a 20dB lower recording than the main channel
b) CH1 -> XLR 1 Mic | CH2 -> XLR 1 <- you can set individual audio levels manually
This is a quote from BMD support which a user got as an answer about a):
Regarding the XLR Mic Backup feature; when properly set, the second channel will bring in the original mic input signal at 20dB lower than the standard Mic input giving you extra headroom in case loud noises occur. The mic backup level is a fixed "line" level and does not follow the adjustments to gain levels on the standard mic input. Levels on the mic backup channel will be detected on the onscreen audio meters when the standard mic input channel exceeds 0dB.
SourceAnd I found the audio specs:
Available audio gain in dB (decibels) from XLR inputs:- LINE input has fixed gain to support maximum +24 dBu.
- MIC Preamp Gain Range = +10 to +65 dB.
- MIC Preamp PAD = -20 dB.
- MIC Preamp Input Signal Range (for 0dBFS) without 20dB PAD = -50 to +5 dBu.
- MIC Preamp Input Signal Range (for 0dBFS) with 20dB PAD on = -30 to +25 dBu.
Audio signal to noise specification from XLR inputs- XLR MIC Preamp has E.I.N. (Equivalent Input Noise) = -128 dBV(A) or better.
- XLR LINE input has a typical Noise Floor = -118 dBFS(A) or better.
- XLR MIC Back Up has a typical Noise Floor = -117 dBFS(A).
