Page 11: Configuring The Inputs And 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 connectors, depending on the model). Each input sums the left and right channel to a mono signal. This mono signal is routed directly to the mix outputs, bypassing the automixing process. -
Page 12: Setting Intellimix
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 and can be customized to excel in any application where multiple microphones are used at once. In all modes (except Manual), MaxBus ensures that only one channel is opened per sound source. -

Page 19: Digital Feedback Reduction (Dfr)
DFR is available for the SCM820 on firmware versions 1.1.0 and higher. For a unit running an earlier firmware version, use the Shure Update Utility application to update the mixer to a new firmware. The application is available from www.shure.com/software. -
Page 20: Assigning Dfr
⑬ ⑭ Assigning DFR Two DFR blocks are assignable to any channel input or mix output. When using two or less microphones, assign the DFR to those channels to prevent feedback from routing to the mix bus. Additionally, if a microphone is designated for a chairperson or host, DFR should be applied to that channel to ensure that remains stable and does not feed back. -
