About Shure SCM820

Shure SCM820 Features

  • IntelliMix technology: Delivers seamless automatic mixing and reduced background noise through dynamic channel gating and attenuation
  • IntelliMix technology: NAT (Noise Adaptive Threshold) continuously adjusts the activation threshold for opening a channel
  • IntelliMix technology: Number of Open Microphones Attenuation (NOMA) determines the amount of gain attenuation for a mix output when the number of active microphones changes
  • IntelliMix technology: Last Mic Lock-On (LMLO) keeps the most recently activated microphone open until another microphone is activated
  • IntelliMix technology: MaxBus ensures that only one channel is opened per sound source, reducing comb filtering for clear and intelligible speech
  • IntelliMix technology: 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: DB25 or logic-enabled block connector models available, each with 8 inputs
  • Enhanced I/O Support: Per-channel direct outputs allow the SCM820 to be used as an insert processor
  • Enhanced I/O Support: Mix A and B outputs with selectable mic or line level connect to a sound reinforcement system, mixing console, or recording device
  • Enhanced I/O Support: 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
  • Enhanced I/O Support: Aux inputs on both the front and back panel easily connect to media players
  • Enhanced I/O Support: 1/4" (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
  • Comprehensive Control: Output mix controls and meters enable front-panel master gain and limiter control as well as signal monitoring
  • Comprehensive Control: LED meter rings display input audio or IntelliMix gain levels for each channel
  • Comprehensive Control: Browser-based control software delivers comprehensive software control, monitoring, routing and configuration of all signals and settings and adds a parametric 8-band EQ
  • Advanced Networking: Standard Ethernet or Dante digital networked audio configurations available
  • Advanced Networking: Dante-equipped models enable multi-channel audio networking over Ethernet
  • Advanced Networking: Dante upgrade card available for standard Ethernet models
  • Advanced Networking: Dante virtual soundcard license included to connect a computer to a Dante network for recording, playback and internet calling between Dante-equipped devices
  • Advanced Networking: Link Dante-equipped SCM820 mixers to form large automixes of up to 12 units (96 channels of audio)
  • Advanced Networking: Control system compatible (AMX, Crestron)
  • Digital Feedback Reduction: Two channels of patented Shure DFR (Digital Feedback Reduction)
  • Digital Feedback Reduction: Assignable to input channels and mix outputs
