VREF
3.8V regulator output pin.
Output requires capacitor for stopping
oscillation. Output pin has built-in precharge
and discharge circuits, so there is no problem
with start-up or shut-down even with a large
capacitor. This pin is for connection to the
high-band filter.
Pin for high band filter connection.
Main volume output pin.
OUT1 is the volume output for Channel 1.
OUT2 is the volume output for Channel 2.
For prevention of shock noise during
step switching.
