Unit (resistance:
)
Pin No.
Function name
Internal circuit for pin
Description of function
18
Recording bias
automatic control filter
Wave detection is performed when
connected to GND through a
capacitor.
19
Supply voltage (VCC)
VCC max=14V
VCC = 8.5 V to 12.5 V
20
Ripple filter
Power supply
of each
circuit block
Ripple rejection is performed when
connected to GND through an
electrolytic capacitor for the filter.
21
EP/LP/SP Control
When the voltage on
pin 21 is 3.6 V to 6.0 V: EP;
when 1.8 V to 2.6 V: LP;
when0Vto1.0 V: SP
Switch On Pin Number
22
MUTE Control
When the voltage on
pin 22 is 2.5 V to 6.0 V: MUTE on;
when0Vto1.5 V: MUTE off
23
EE/PB Control
When the voltage on
pin 23 is 3.0 V to 6.0 V: EE;
when0Vto1.0 V: PB
24
REC/EE Control
When the voltage on
pin 24 is 3.0 V to 6.0 V: REC;
when 0V to 1.0 V: EE
However, REC mode is entered only
when the voltage on pin 23 is 3.0 V
to 6.0 V.
