*1: Input voltage amplitude at f=1 kHz such that total output harmonic distortion is 1%. However, signals

input to SG1 and SG2 are in phase (phase difference 0°).

*2: Input voltage amplitude at f=1 kHz such that total output harmonic distortion is 1%. However, signals

input to SG1 and SG2 are opposite in phase (phase difference 180°).

*3: Voltage at which bypass pin (pin 22) is regarded as H

*4: Voltage at which bypass pin (pin 22) is regarded as L

*5: When Vbyp=5V, current flowing into bypass pin

*6: When Vbyp=0V, current flowing from bypass pin

*7: Defined as the difference in pin 13 DC output voltages on switching from normal stereo mode to pseudo-stereo mode.

*8: Defined as the difference in pin 3 DC output voltages on switching from normal stereo mode to pseudo-stereo mode.

*9: Defined as the difference in pin 4 DC output voltages on switching from normal stereo mode to pseudo-stereo mode.

*10: Defined as the difference in pin 5 DC output voltages on switching from normal stereo mode to pseudo-stereo mode.
