550TCP Terrestrial Channel Processor

The DRACOM 550TCP is a high 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 frequencies are easily set with front panel pushwheel switches. A/V ratio and output level controls are also provided along with IF loop-thru connections to offer exceptional flexibility.

. Low-cost NTSC channel processor

. Synthesized input tuning of off-air TV channels 2 through 69, set by a front panel pushwheel switch.

. Synthesized RF output on CATV channels 2 through 78 and 95 through 99, set by a front panel pushwheel switch.

. I F SAW filter

. High output power adjustable to +60 dBmV

. IF loop-thru connections for scrambling encoders or IF stereo processors.

. Optional version (550TCP/T) with "T" channel inputs.
