Don’t we all love to hate Behringer?!
But how is it actually measuring?
1.Microphone in XLR Balanced in main out.
Gain @min. (10dB labeld 10,5 messured)
Channel 0dB
Main 0dB
VU meter showing 0dB at Input level 433mVRMS (-7.3dBV) (-12dbFS)
output level is 1.43VRMS (+3.1dBV) -14,3dBFS
gain about 10,8dB
This measurements is limited by noise and the performance of my audio interface!
We can’t just reed of the SINAD number and call it a day!
We can see the first distortion product is abut -106dB below the signal but hum and noise is only at -95dB.
Distortion spec is "0.007% +4dBu" aka. -83dB @1.8dBV
If i add second and third harmonic i get about -103dB @ 5.3dBu
2.Microphone in XLR Balanced in --> Main out.
Gain @min.
Channel "+15"dB max.
Main "+15"dB max.
VU meter showing 0dB at Input level -43dBFS (-38,3dBV) (0.0121V)
output level is 1.42VRMS (+3.0dBV) -14.1dBFS
gain about 41,3dB
With about 41,3dB of Gain the noise from the Mixer becomes strong enough to be way over the DAC and ADC noise
3.Microphone in XLR 150Ohm short --> Main out.
Gain @min.
Channel "+15"dB max.
Main "+15"dB max.
Jnoise meter shows -88dBFS of noise. before it was -16.5dBFS with (+3.0dBV) input.
Output voltage noise is about -74dBV but remember this is with 10dB Preamp gain + 15dB channel gain + 15dB main gain (41,3dB in toatal)
EIN 115,8dBV @ 150Ohm
Same thing but preamp gain at max:
Output voltage noise is -58.1dBFS (+13,5) = -44,6dBV but remember this is with 60dB Preamp gain + 15dB channel gain + 15dB main gain (91dB in toatal)
EIN gain max. 135,6dBV @ 150Ohm (-133.38dBu)
Datasheet value is -129,5dBu
"0dB VU meter"
SINAD at "0dB VU meter" is is about 85dB?
SNR is about 107dB
Distortion is ruffly at -100dB
EIN -135.6dBV
This is all very ruff and there is a lot of error margin. but i see no reason not to believe the specs
