(5) ALC control pin and ON/OFF level
The ALC ON/OFF control circuit is configured as shown left.
When a voltage of (VBE1+VBE2) = 1.5 V or greater is applied to the
ALC CONT17, the potential on the ALC IN (pin 8) drops to GND
level. The ALC is turned OFF (ALC function release).
Threshold
region
REC amplifier output VOAC is controlled by the ALC CONT
voltage and the threshold region has a range of approximately 0.5 V.
The ALC CONT voltage is set to 1.0 V or less/1.5 V or greater to
turn ON/OFF the ALC, respectively.
(Refer to Data VOAC, V8, I1 – VALC CONT.)
