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
• Browser-based 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)

• Two channels of patented Shure DFR (Digital Feedback Reduction) 
• Assignable to input channels and mix outputs 
• Automatic feedback detection and filter deployment 
• Up to 16 filters per channel 
• 25 Hz to 20 KHz bandwidth
• Up to 18 dB gain reduction per filter
• Selectable low / high Q filter width (1/40th or 1/70th octave)
• “Freeze” feature that locks depth and frequency of existing filters to avoid unwanted automatic changes
• Auto-clear on power cycle or timeout that returns filter settings to a pre-defined state for the next event
• Ability to save current settings to use later or load preexisting setups
