The AT-DMM828 SmartMixer® latest addition to Audio-Technica’s family of automatic mixers. This digital automatic 8-channel matrix mixer is designed to provide automatic mixing functions for installed sound, house of worship, broadcast and conference applications. Engineered with intuitive, easy-to-use software GUI, the AT-DMM828 automatically keeps the number of open microphones to a minimum, bringing background noise and feedback under control and providing increased clarity and audio quality.

Features:

  • Eight balanced inputs allow use with both mic- and line-level signals
    Each input provides:
     -Phantom power (48V), individually selectable
     -Individual gain and volume controls
     -Gate attenuation (adjustable)
     -Low-cut filter (individually selectable via SmartMixer Software)
  • RS232 and USB data ports provide a connection point for a PC with included SmartMixer Software
  • Compatible with Crestron® and AMX® systems
  • External control capability enables the SmartMixer to activate other devices
     Force-On – allows an external contact closure to force its associated input to turn on
     Force-Off – allows an external contact closure to force its associated input to turn off
     VCA Control – Volume up/down
  • Selectable NOMA (Number of Open Mics Attenuated) circuitry helps control feedback
  • Priority pre-select feature allows priority of each microphone to be independently assigned
  • Last Mic On selectable for continuous room ambiance
  • Linking capability for 16 units (up to 128 channels)
  • Equipped with eight balanced audio outputs to drive amplification systems or other equipment
