Setting Intellimix; Mixer Mode Descriptions - Shure Digital IntelliMix SCM820 Manual

The output limiter prevents distortion during loud program peaks without affecting normal program levels. This prevents
overloading the devices connected to the mixer outputs.

Auxiliary (Aux) Input
The SCM820 features two auxiliary inputs: an 1/8" jack on the front panel and a back panel input (block connector or RCA con-
nectors, depending on the model). Each input sums the left and right channel to a mono signal. This mono signal is routed di-
rectly to the mix outputs, bypassing the automixing process. Use this input for sources such as an MP3 player or computer
speaker output.
Digital Channels
When the mixer is connected to a Dante network, the left and right channels are accessible before they sum to the mono signal
for the mix outputs. Use the Aux L and Aux R channels in Dante Controller to route audio to and from the aux channel.

Setting IntelliMix

The SCM820 uses IntelliMix to select channels to open in a mix, while attenuating the gain of closed channels. IntelliMix is
available in three presets to excel in any application where multiple microphones are used at once. In all modes (except Manu-
al), MaxBus ensures that only one channel is opened per sound source.

Mixer Mode Descriptions

The SCM820 features five mix modes: Classic (Default), Extreme, Smooth, Custom or Manual.
Classic
Classic mode emulates the classic Shure SCM810 automixer (in its default settings). It is renowned for fast-acting, seamless
channel gating and consistent perceived ambient sound levels. The Classic mode excels in most applications, specifically
sound reinforcement and teleconferencing.
