IntelliMix® Technology

  • Delivers seamless automatic mixing and reduced background noise through dynamicDynamic mics have a simple, rugged construction and can handle very high sound pressure levels.Read moreGo to the glossary channel gating and attenuation
  • NAT (Noise Adaptive Threshold) continuously adjusts the activation threshold for opening a channel.
  • Number of Open Microphones Attenuation (NOMA) determines the amount of gain attenuation for a mix output when the number of active microphones changes.
  • Last Mic Lock-On (LMLO) keeps the most recently activated microphone open until another microphone is activated in order to maintain a perceived ambient sound during long pauses
  • MaxBus ensures that only one channel is opened per sound source, reducing comb filtering for clear and intelligible speech.
  • IntelliMix® Modes offer four different mixer mode presets of reliable automixing styles (Classic, Smooth, Extreme, Custom) as well as Manual Mixing mode to quickly tailor the mix for a particular application.

 

Enhanced I/O support for greater application flexibility and digital connectivity

  • DB25 or logic-enabled block connector models available, each with 8 inputs
  • Per channel direct outputs for use as an insert to a mixing console or recording
    Mix A and B outputs with selectable mic or line level, connect to a sound reinforcement system, mixing console, or recording device.
  • Dual mixer operation enables routing of independent automixes to the mix A and B outputs, allowing two entirely different mixes to result from the same set of inputs.
  • Aux inputs (front panel:3.5 mm, back panel: block connector) easily connect to media players
  • ¼” (6.35 mm) stereo headphone output for channel solo and mix monitoring

Comprehensive Control

  • Channel control knobs allow quick adjustment of gain, limiter and EQ settings, and solo/mute functions on input channels
  • Output mix controls and meters enable front-panel master gain and limiter control as well as signal monitoring
  • LED meter rings display input audio, IntelliMix gain levels or EQ settings for each input channel
  • Browser-based control software delivers comprehensive software control, monitoring, routing and configuration of all signals and settings and adds a parametric 8-band EQ (incl. High- and Low-shelf EQ)

Advanced Networking

  • Standard Ethernet or Dante™ digital networked audio configurations available
  • Dante-equipped models enable multi-channel audio networking over Ethernet.
  • Dante Upgrade card available for standard Ethernet models
  • Link Dante-equipped SCM820s to form large automixes of up to 12 units (96 channels of audio)
  • Control system compatible (AMX, Crestron).
