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.
