At minimum gain (0 dB)
At maximum gain (+60 dB)
-94 dB for mic input at 60 Hz for max. output = +24 dBu
-91 dB for mic input at 10 kHz for max. output = +24 dBu
Mic input, with I/P = 0 dBu, gain = 0 dB @ 1 kHz input to channel A,
channel B output = -85 dB
-20 dB to +10 dB in 10 dB steps, plus 0 dB to +20 dB continuously
