AVT 200HD Tuner • Setup GuideThe Extron AVT 200HD is a high performance tuner that receives ATSC over-the-air broadcast signals and delivers high-definition television (HDTV) video simultaneously on HDMI®, RGBHV, and YUV outputs. It outputs pulse code modulation
(PCM) stereo or Dolby® Digital surround (AC-3) formatted audio signals with simultaneous S/PDIF digital and analog
balanced and unbalanced stereo. The AVT 200HD also provides clear QAM (unencrypted) cable (CATV) decoding and
standard definition video outputs. Additional integrator and user-friendly features include a multi-function on-screen
display and channel presets.
This guide provides instructions for an experienced installer to install and connect the AVT 200HD : For full installation, configuration, and operation details, see the AVT 200HD User Guide, available at
