CH2 Head AMP Inverter phase
input pin (decoupling with
capacitance).
CH2 Head AMP positive phase
input pin (PB signal input pin).
CH2 REC AMP output pin.
Power supply pin for CH2 REC
AMP and CH2 Head AMP.
Q adjusting pin for medium range
frequency compensation circuit.
Controls Q through current value
by connecting resistance between
GNDs; Mutually effected by MT
F . Do not connect capacitance.
CH2 REC AMP input pin.
Mix circuit output pin for CH2.
Boost level adjusting pin for CH2
medium range frequency
compensation circuit; variable
between 0 and +12dB at 4.2 to 0.8V.
RF switching pulse input pin for
CH switchover.
GND pin for CH2 REC AMP and
CH2 head AMP.
PCM AREA input pin;
During High period after recording,
MUTE is applied to PB VIDEO
output.
Level of low range REC signals
(Chroma, AFM, ATF rec. with
VIDEO) can be boosted by 0 to
3dB by voltage (0 to 5V) applied
to this pin.
