HCP2550A Heterodyne Channel Processor
The Drake HCP2550A is a high quality, frequency agile channel processor capable of converting any VHF, UHF, or CATV input signal to any standard output channel between 54 through 550 MHz. Input and output frequency, including output frequency offset, are easily set with front panel push wheel switches. A/V ratio and output controls are also provided along with IF loop-through connections to offer exceptional flexibility.
- Synthesized input tuning of Off-Air TV channels 2 through 69, standard CATV channels 2 through 125, and IRC, HRC channels 1 through 125. All set by a front panel push wheel switch.
- Synthesized RF output on CATV channels 2 through 78 and 95 through 99, set by a front panel push wheel switch.
- Selectable pre-amp and AFC provides stable reception of weak or out-of-tolerance signals
- Switch selection of plus, minus or no offset of output frequency
- Dual SAW filter IF allows adjacent channel operation in a crowded CATV environment
- Selectable and adjustable threshold level allows internal carrier substitution for below threshold input signal levels
- IF loop-thru connections for scrambling encoders or IF stereo processors
- High output power adjustable to +60 dBmV
- Available with "T" Channel upconverter option for reception of channels T7 - T14.
- Emergency Alert System (EAS) ready with alternate composite IF inputs.
- Made with pride in the U.S.A.
