Ramp pulse rising slope
switchover pin.
Low: 32µA/µs 0.6V or below
High: 17µA/µs 2.3V or above
(The fall time is 32µA/µs in
both cases.)
EVR adjusting pin to
determine middle-tune Q.
Increasing the applied
voltage increases Q.
Power supply pin for CH1 REC
amplifier and PB amplifier.
EVR adjusting pin for the CH1
recording dumping level.
Reducing the applied voltage
strengthens dumping.
CH1 recording output pin.
Open collector.
