Extreme
Extreme is an aggressive variation of the Classic mode, configured to achieve maximum gain before feedback by completely
attenuating closed channels. Only open channels add to the system levels and ambient sound. Extreme mode is designed for
sound reinforcement applications.

Channel Gain in Extreme Mixer
1 Talker
Full gain is applied to the open channel. Closed channels are fully attenuated.
2+ Talkers
As additional channels open, NOMA factor decreases the level of all channels.
Manual
Manual mode deactivates IntelliMix to allow the SCM820 to operate as a standard mixer. All Channel Status LEDs remain on in
this mode to indicate there is no IntelliMix attenuation. Channel and mix equalization, output limiter and mix bus routing are still
active in this setting.
Tip: Be careful when switching to Manual mode, as all microphones will gate open to full gain, which may result in feedback.
Custom
Custom mode allows IntelliMix parameters to be fine-tuned and tailored from the web application. The mixer automatically
switches to Custom once a parameter is changed in Classic, Extreme or Smooth mode. Theses configurations are saved to the
device and will persist after the mixer is turned off and restarted.
