Internal circuit for pin

Description of function

Output impedance → 50Ω (typ)

9

LINE AMP PB input

10

LINE AMP LINE input

11

ALC FILTER

Inputs the playback signal from the

Equalizer Amplifier. Because the

input impedance is as high as 120

kΩ, a 0.1 µF ceramic capacitor can

be used for the coupling capacitor

on pin 9.

Inputs EE and REC signals.

The reference input is set by

resistors R1 and R2. The amplifier

gain is fixed at 21.5 dB. In addition,

because the input impedance is as

high as 120 kΩ, a 0.1 µF ceramic

capacitor can be used for the

coupling capacitor on pin 10.

Wave detection is performed when

connected to GND through a

capacitor. In addition, the attack and

recovery time is set by the C and R

time constants.

ALC input wave

detection

Inputs the Line Amplifier output

signal. The ALC level is set by the

resistors R1 and R2.
