(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.

(7) EVR control characteristics

The headphone amplifier is controlled by changing the

resistive potential division ratio.

This path is not controlled by EVR or the mute function.
