The 8685 is Orban's second-generation surround/2.0 processor. In addition to the effective automatic loudness control of its predecessor, the 8685 offers new input/output capabilities that include support for SDI and HD-SDI and for Dolby E. Dual redundant power supplies help ensure maximum uptime. In addition to surround processing, the 8685 can simultaneously provide up to three channels of 2.0 processing, allowing it to provide all the audio processing necessary for a typical ATSC broadcast with multiple subchannels. Like the 8585, the 8685 is dialnorm-aware. Loudness control is excellent when measured by the ITU BS.1770-2 and EBU R-128 standards or by the 8685's built-in CBS Loudness Meters, allowing stations to comply effortlessly with the requirements of the CALM act.


  • Automatic loudness controller for simultaneous control of four stereo programs and one surround program.
  • Surround processing can use one 2.0 processor to create a loudness-controlled and peak-controlled downmix output that can drive an analog TV transmitter.
  • ATSC A/85 (CALM Act) and EBU R 128 compliant via third-generation CBS Loudness Controller.
  • Includes CBS and BS.1770-2 loudness meters.
  • Automatic dialog intelligibility control.
  • 3G HD-SDI and AES3id I I/O.
  • SDI provides video delay to match processing delay, ensuring correct AV sync.
  • Front-panel headphone output.
  • Seamless switching of audio, video, and metadata between loudness control and pass-through modes.
  • Color GUI on active-matrix quarter-VGA display allows full front-panel adjustment of all setup and processing parameters.
  • Dual-redundant universal power supplies.
  • Supports optional Penteo 2.0 Æ 5.1 upmixer.
  • Three rack units high.
