Factory setting is 0 volts, with the pot turned full clockwise.
(See page 16, Section 9.

for more details.)
⑪
ALC
RCA Jack for ALC Voltage Output. Negative DC voltage
appears at the center pin, which is fed back to the ALC terminal
of the transceiver. ALC is used to keep the amplifier output
power at certain limits. Also it is useful when the transceiver
output power is higher than 100 W (See page 16, Section 9.
ALC Connection
). Also consult your HF transceiver’s user
manual.
⑫
SEND
RCA Jack. Connect the control cable from the ACC terminal (or
SEND, TX GND etc.) of the transceiver. Electrical conditions
are 12 V DC of open voltage at receive mode (RX), and short
current of 35 mA at transmit mode (TX).
⑬
FAN POWER
