Shure SCM820 Specification Sheet

SCM820 Digital Automatic Mixer

Overview

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

Features

• Seamless automatic mixing and reduced background noise through dynamic channel gating and attenuation

• 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.

• DB25 or logic-enabled block connector models available, each with 8 inputs

• Per channel direct outputs for use as an insert to a mixing console or recording

• Mix A and B outputs with selectable mic or line level connect to a sound reinforcement system, mixing console, or recording device.

• Individual channel control for quick adjustment of gain, limiter, EQ, and solo/mute

• LED meter rings vibrantly display real-time settings and output levels

• Browser-based control software delivers comprehensive software control, monitoring, routing and conﬁguration

• 3rd party control system (AMX®, Crestron®) compatible

• Models available with Dante™ digital networked audio for multi-channel audio networking over Ethernet

• Dante upgrade card available for standard Ethernet models

• DFR (Digital Feedback Reduction) adds two channels of adaptive EQ ﬁltering to ﬁnd and attenuate feedback frequencies
