Multi-Port Hub PTT Operation
When a single radio is used,
receive audio will be heard in
both ears of the NoizeBarrier TAC
(only) headset. When two radios
are used, primary radio comms
(generally from the
MAIN
jack and using
PTT 1
) will be
heard in the left ear; secondary audio (on
PTT 2
or
3
) will
be heard in the right ear. If three radios are in use, the third
radio plugged into
AUX
will be heard in both ears.
Installation
Note that the connectors on the Multi-
Port Hub PTT are keyed to create proper
alignment of the connector pins.
1. Plug the audio connector cable on
the NoizeBarrier TAC headset into
the jack marked HDST on the top
of the hub.
2. Plug a radio connector cable (see page 4) into
the bottom of the hub. The cable must be the
appropriate cable for the radio platform in use. For
use with one radio, plug the connector into
the jack on the hub marked
PTT 1-2 MAIN
.
3. Plug the other end of the radio cable into the
radio or device.
4. If more than one radio is used, the
MAIN
jack is
for the primary radio. With the use of a Y-cable the
MAIN
jack is for primary and secondary comms.
