Specs
Frequency response (wet and dry) = 2 Hz–18 KHz
Signal-to-noise (“A” weighted) = at +4 dBu
in to out = -90 dB
output only = -100 dB
at -10 dBV
in to out = -90 dB
output only = -95 dB
THD + Noise (“A” weighted) = better than .0032% (-90 dB)
at input levels of -12 dB and below
Dynamic range = 96 dB
IM distortion (SMPTE) = 0.05%
Crosstalk between channels better than -80 dB (1 KHz)
