Internal circuit for pin

Description of function

Output inpedance → 50 Ω (typ)

Inputs the recording signal from Line

Amplifier.

The recording current is set by the

resistors R1 and R2. 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 14.

Output impedance → 50 Ω (typ)

Switches the high-region peaking

frequency during recording and

playback.
