Description

Spec Sheet

Designed for use in speech applications including sound reinforcement, broadcasting, and recording, the SCM820 uses IntelliMix® technology to dramatically improve audio quality when many channels of microphones need to operate simultaneously.

Multiple I/O configurations and networking options ensure analog and digital connectivity between devices.

IntelliMix Technology

  • Delivers seamless automatic mixing and reduced background noise through dynamic 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
  • MaxBus ensures that only one channel is opened per sound source, reducing comb filtering for clear and intelligible speech
  • IntelliMix Modes offer five different mixer mode presets of reliable automixing styles (Classic, Smooth, Extreme, Custom, or Manual) 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 allow the SCM820 to be used as an insert processor
  • 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 on both the front and back panel 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 or IntelliMix gain levels for each channel
  • Windows® 10 control software delivers comprehensive software control, monitoring, routing, and configuration of all signals and settings and adds a parametric 8-band EQ
  • Works with SystemOn Audio Asset Management Software

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 SCM820 mixers to form large automixes of up to 12 units (96 channels of audio)
  • Control system compatible (AMX, Crestron)

Digital Feedback Reduction

  • Two channels of patented Shure DFR (Digital Feedback Reduction)
  • Assignable to input channels and mix outputs
  • Automatic feedback detection and filter deployment
  • 16 filters per channel
  • 25 Hz to 20 KHz bandwidth
  • Up to 18 dB gain reduction per filter
  • High Q filter width (1/70th octave)
  • “Freeze” feature that locks depth and frequency of existing filters to avoid unwanted automatic changes
