PNP-7D CABLE

1. Connect a Phono cable from the AMP jack
of the ARB to the Amplifier’s Relay.

CAUTION

CAUTION::::

CAUTIONCAUTION

DO NOT use the ARB-704 with amplifier
relays that are not pulled to ground to
activate!

If the amplifier has a standard RCA phono
plug it will always be safe to use with this
unit

The relay or amplifier control system
MUST be the type that is pulled to ground
to activate! Nearly all commercial
amplifiers manufactured after the mid
1960’s is safe to use with this unit. The
ARB-704 connects between the radio and
amplifier, preventing damage to the radio
from amplifier keying voltages.

The ARB-704 works with all standard
manufactured amplifiers including those
with positive, negative, and AC relay lines.
This includes, but is not limited to,
Ameritron, B&W, Collins, Command,
Dentron, Heathkit, Kenwood, and Yaesu
amplifiers.

The safest way to tell if the ARB-704 will
work is to look at the relay connection on
the amplifier panel. If the connection is
through a phono (RCA) jack, or has one
terminal directly grounded to the chassis,
this unit will almost certainly work.

2. If using ALC, connect a Phono cable from
the ALC of the ARB jack to the Amplifier’s
ALC.

3. Connect the 5-pin end of the “plug and

play cable” in to the multi-port of the ARB.

Then, connect the 7-pin end into the
remote jack of the Kenwood.

4. NOTE: DO NOT connect power to the

ARB’s power jack. Except for TS
940, 830, 530, and 130

The ARB’s power and radio jack is not used for
this application. Except
NOTE section connect Red to positive and
Black to ground or negative.

When the transceiver is placed into transmit,
the light on the ARB will light and the amplifier
will go into transmit mode.
