(6) Output level between SYSTEM BEEP IN and LCH
OUT (BA7786FP-Y)
Inputting a pulse wave to SYSTEM BEEP IN causes
LCH OUT to output a pulse wave. The output level of
this pulse wave depends on the resistance between pin
7 and GND and between pin 8 and GND, and is calcu-
lated as follows.
This path is not controlled by EVR or the mute function.
(7) EVR control characteristics
The headphone amplifier is controlled by changing the
resistive potential division ratio.
