    Required Accessories

    The AQT (ATSC/QAM Transcoder Series) from Blonder Tongue features a state-of-the-art approach and offers top notch performance and functionality. It incorporates a scalable modular design that allows from one to eight transcoder module units as well as a single combination power supply & control module to be added, removed or swapped at any time in the 3 rack high chassis. The AQT Series transcoder modules are compatible with off air 8VSB signals to transcode to QAM signals. It is also well suited for regenerating or changing the channel of a QAM signal. The modules are housed in a custom designed chassis intended to accommodate from one to eight different modules as well as specially designed chassis mountable splitters and combiners to make wiring simple and painless. Control of the transcoder units is easily accomplished with a common power supply & control unit via operator selection from the front panel push button controls and back-lit LCD panel. This module interfaces to any of the AQT transcoder modules through a simple 12-pin connector and cable. The control module's brain is a flash upgradeable microprocessor to ensure support for any future development. Support for redundant back-up or `standby' power is also built into every AQT power & control module. This is easily added at any time for an operator by interfacing to the optional standby power supply unit. In addition, the optional AQT Remote Configuration Server provides the ability to remotely control and monitor any of the transcoder modules over the Internet - this makes turning off a problem unit and reprogramming a live spare a quick fix preventing an immediate truck roll
