Compact
Liquid-Cooled Transmitter, Designed for NextGenTV / SFN:
Hitachi-Comark has now developed the PARALLAX Compact —the industry’s most compact, next generation low to medium power liquid-cooled, solid-state DTV transmitter available for either UHF or VHF Band 3.
PARALLAX Compact is a simplified and condensed version of our family of DTV transmitters. The new Compact design shrinks the entire transmitter into a simple and cost effective 27RU transmitter cabinet. The benefits of PARALLAX Compact are that it drastically simplifies the on-site installation and setup time as well as reduces the floor space requirements. Much like the larger PARALLAX transmitters, the Compact uses an external cooling pump system and outdoor liquid-to-air heat exchanger.
PARALLAX features unique engineering that allows for the highest signal quality, reliability, and efficiency while keeping the cost of ownership as low as possible. We have incorporated the latest control system software/firmware named "OCEAN". The new Ocean control system provides users with improved ease of use, comprehensive reports and other new features, continuing our commitment to bring latest and greatest technologies to our broadcast customers. Most importantly, the Compact offers flexibility: no matter how large or small, each station is assured top-notch performance for its specific needs.
PARALLAX Compact features:
- Large 15" touch-screen user interface with the latest "Ocean" control system
- RF output of 1.8kW to 10kW TPO in UHF
- RF output of 1.5kW to 8.2kW TPO in VHF Band 3
- Separate indoor cooling module with coolant tank, pump(s), sensors
- Outdoor liquid-to-air heat exchanger
- Simple 6 or 8-pole RF mask filter
- Optional unitized floor mount RF system with patch panel (or motorized output switch), station dummy load
- Unique vertical high-gain Power Amplifier (PA) “building block” modules, ~50lbs
- Broadband Doherty amplifier technology produces high AC to RF efficiency
- Same RF output power rating in ATSC 1.0 or 3.0 / NextGen TV
- Liquid cooled amplifiers mean high reliability, simple installation, easy maintenance
- Commercial off-the-shelf (COTS) Hot-Swap AC to DC rectifiers provide >96% efficiency
- Industry leading Digital Adaptive Pre-correction (DAP) that provides the highest RF signal performance
- Manufactured, serviced, and supported in the U.S.A.
