Description

Recording mute

ON/OFF selection pin.

∗ Recording mute is

controlled with DC

voltages of 0 to 5V.

High = Recording

mute OFF

Low = Recording

mute ON

∗ Soft mute and fader

can be switched

over by changing

the time constant of

the external time

constant circuit.

Recording equalizer

amplifier input pin.

Connect to GND for

positive/negative

dual power supplies.

VCC/2 (center

potential) for a single

power supply.

(Connect a capacitor

of 10µF or more)

Connection pin of an

external capacitor for

low frequency boost.

∗ When low

frequency boost is

unnecessary,

connect to GND for

positive/negative

dual power

supplies; connect a

capacitor (3.3µF or

more) for a single

power supply.
