550TCP TERRESTRIAL CHANNEL PROCESSOR
DESCRIPTION
The DRACOM 550TCP is a quality, frequency agile
channel processor capable of converting any VHF or UHF,
off-air signal to any standard output channel between 54
and 550 MHz. Input and output frequency are easily set
with front panel pushwheel switches. A/V ratio and output
level controls are also provided along with IF loop-through
connections to offer exceptional flexibility.
The synthesized input tuning permits reception of off-air TV
channels 2 through 69. A front panel signal indicator lights
for input signal strengths greater than a threshold value.
RF output level is front panel adjustable to
+60 dBmV maximum.

IF loop-thru capability in the 550TCP supplies a padded
IF output prior to channel conversion. This feature
provides the capability to replace the standard internally
generated IF output with an alternate source of composite
IF, or allows the insertion of IF scrambling equipment.
Coaxial connectors are provided for the RF Input, the
IF Loop-out and Loop-in, and the RF Output. All of the
mentioned features, combined with a carefully
low intermodulation output stage, provide reliable operation
in a densely crowded SMATV or
The 550TCPT is a 550TCP with a built-in "T" channel
upconverter. See page 5 for details.
