8-Channel Digital IntelliMix Automatic Mixer

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

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

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

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

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
