Shure SCM820-DB25
8Ch Intellimix Digital Mixer with DB25 Connectors


The Shure SCM820-DB25 is an 8-channel digital automatic mixer with DB25 connectors, designed for use in speech applications, including sound reinforcement, broadcasting and audio recording. It uses patented Intellimix technology to dramatically improve audio quality in any application where multiple microphones are required.


IntelliMix technology

  • Delivers seamless automatic mixing and reduced background noise throughdynamic channel gating and attenuation
  • NAT (Noise Adaptive Threshold) continuously adjusts the activationthreshold for opening a channel
  • Number of Open Microphones Attenuation (NOMA) determines the amount ofgain attenuation for a mix output when the number of active microphoneschanges
  • Last Mic Lock-On (LMLO) keeps the most recently activated microphone openuntil another microphone is activated
  • MaxBus ensures that only one channel is opened per sound source, reducingcomb filtering for clear and intelligible speech
  • IntelliMix Modes offer five different mixer mode presets of reliableautomixing styles (Classic, Smooth, Extreme, Custom, or Manual) to quicklytailor 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 insertprocessor
  • Mix A and B outputs with selectable mic or line level connect to a soundreinforcement system, mixing console, or recording device
  • Dual mixer operation enables routing of independent automixes to the mix Aand B outputs, allowing two entirely different mixes to result from the sameset of inputs
  • Aux inputs on both the front and back panel easily connect to mediaplayers
  • 1/4" (6.35 mm) stereo headphone output for channel solo and mixmonitoring

Comprehensive control

  • Channel control knobs allow quick adjustment of gain, limiter, and EQsettings, and solo/mute functions on input channels
  • Output mix controls and meters enable front-panel master gain and limitercontrol as well as signal monitoring
  • LED meter rings display input audio or IntelliMix gain levels for eachchannel
  • Browser-based control software delivers comprehensive software control,monitoring, routing, and configuration of all signals and settings and adds aparametric 8-band EQ

Advanced networking

  • Standard Ethernet or Dante™ digital networked audio configurationsavailable
  • Dante-equipped models enable multi-channel audio networking over Ethernet
  • Dante upgrade card available for standard Ethernet models
  • Dante virtual soundcard license included to connect a computer to a Dantenetwork for recording, playback, and internet calling between Dante-equippeddevices
  • Link Dante-equipped SCM820 mixers to form large automixes of up to 12units (96 channels of audio)
  • Control system compatible (AMX, Crestron)
