RACK MOUNTING
Adequate ventilation is very important in
multichannel installations. Units should be
spaced apart vertically by at least 1.75"
wherever possible, and some air movement is
mandatory in enclosed rack cabinets.
Excessive heat will shorten component life and
performance will be degraded without
proper cooling.

R1 - IF OUTPUT Connector
This is the 44 MHz IF output. The level is
+30 dBmV.
R2 - DC INPUT Connector
This 3-pin connector (Male) accepts the
appropriate mating DC power cable. Observe
proper orientation and wiring.

All connections to and from each upconverter
are made through the rear panel.
DESCRIPTION
Figure 3 shows a typical installation utilizing the
Drake DRMM12 rack with 4 DDC864
downconverters, and 4 DUC upconverters.
A PS8 power supply module is used to power
all units.

RACK MOUNTING
Adequate ventilation is very important in
multichannel installations. Units should be
spaced apart vertically by at least 1.75"
wherever possible, and some air movement is
mandatory in enclosed rack cabinets.
Excessive heat will shorten component life and
performance will be degraded without
proper cooling.
