Receiver Multicoupler
Rio Rancho, NM
7
Battery Panel
The passband of the multicoupler is marked on the
label on the housing cover next to the battery panel.
IMPORTANT - The frequency of the receivers
installed in the unit must fall within the passband
indicated on the label. Serious signal loss can
result if the receiver frequencies are outside the
Octopack RF passband.
External DC Power
Any external power source can be used if it has the
correct connector, voltage and current capacity. Polar-
ity, voltage range and maximum current consumption
are engraved next to the power jack.
Battery Power
The rear/bottom panel provides a locking power jack
and mounting for two L or M style rechargeable batter-
ies. The batteries must be charged separately with the
charger supplied by the manufacture since there is no
charging circuitry in the Octopack.
Automatic Backup Power
When batteries and external DC are both connected,
power is drawn from the source with the highest volt-
age. Typically, the external source provides a higher
voltage than the batteries, and in the event it fails, the
batteries will immediately take over and the power
LED will begin to blink slowly. The source selection is
handled by circuitry rather than a mechanical switch or
relay for reliability.
Side Panel
Eight balanced outputs are provided on the side panel
of the multicoupler. When the receivers operate in a
2-channel mode, each jack provides a separate audio
channel. In the ratio diversity mode, the receivers
are paired, so adjacent output jacks deliver the same
audio channel.
The connectors are standard TA3M types, with the
same pinout numbering as 3-pin XLR connectors.
