Dual Mixer Operation; Dfr And Audio Processing; Model Variations - Shure Digital IntelliMix SCM820 Manual

Manual mode deactivates IntelliMix to operate as a standard mixer. Channel and mix equalization, output limiter and mix
bus routing are still active in this setting.

Dual Mixer Operation

The SCM820 can operate as a single or dual mixer:
Single Mixer: Channels are routed to a single mix bus that sends the same audio to both Mix A and B outputs. This allows the
same program to be sent to different rooms or recording applications. Output gain, parametric equalizer and limiter can be set
separately for each mix.
Dual Mixer: Two separate buses provide independent automixes for each mix output. This allows two entirely different mixes
to result from the same set of inputs. This is useful when the mixer is being used for two applications. For example, set Mix A to
Classic mode for sound reinforcement, and set Mix B to Smooth for a broadcast feed. As a dual mixer, channels can be routed
to Mix A, Mix B, Mix A and B, or neither mix bus.

DFR and Audio Processing

The SCM820 features two channels of Digital Feedback Reducer (DFR). DFR uses Shure's patented Adaptive Notch Filter al-
gorithm to detect feedback and deploy up to 16 narrow-band notch filters, dramatically improving gain-before-feedback in a
sound reinforcement system. DFR can be applied to any two channels of the SCM820, including the mix outputs.
Additionally, the mixer provides adjustable input equalization, limiting and a parametric output EQ to optimize the sound in any
application.
