BW = 20 Hz to 20 KHz
output muted
BW = 20 Hz to 20 KHz
all gain = 0dB
all gain = 0dB flat; VO = 2VRMS
bass treble at 12dB; VO =
2.6VRMS
VIN = 1VRMS; all stages 0dB
VIN = 1VRMS; Bass & Treble = 12dB

AV = 0 to -20dB
AV = -20 to -60dB
1) SM pin is active low (mute condition)
2) See description of Audioprocessor Part - Bass & Treble filter characteristics programming
