impedance as other Vcc lines (especially lines with large current). (This is not a problem when Vcc1 and
Vcc2 lines are bundled.)

During Mono Sel. R Stereo selection, a signal that has IS IN A (L)
or B (L) or IS IN C (L) or IS IN D (L) added is output. During
Mono Sel. R Mono selection, a signal that is a mixture of a signal
with (L) input added and then lowered 9dB and a signal that with
(R) input added and lowered 9dB. (See Figure B)
A signal that has IS IN A (R) or B (R) or IS IN C (R) or
IS IN D (R) added is output.
A signal that has IS IN A (R) or B (R) or IS IN C (R)
added is output.
