Shure SCM820 Digital IntelliMix Automatic Mixer (Discontinued)

The following product has been discontinued. 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 Automatic Mixer, DB25 Connectors, Dante Digital Audio SCM820-DB25: Digital IntelliMix Automatic Mixer, DB25 Connectors Features 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
