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.
Gating Style: Full
Gain Scaling: Fixed
Off Attenuation: −110 dB
Last Mic Lock On: Disabled
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.

Selecting the Mixer Mode
Press the Mix A or Mix B button on the mixer back panel to scroll
through the five modes. From the IntelliMix tab of the GUI, you can
select a preset or configure the IntelliMix as a Custom setting.
Mixes A and B have the same IntelliMix settings when the
SCM820 is to Single Mixer Operation (default).

Single or Dual Mixer Operation
The mixer can be set to perform one or two automixes:
• Single Mixer (default): Channels are routed to a single mix bus
that sends the same audio to both Mix A and B outputs. Limiter
and master gain can still be set independently for both outputs.
• Dual Mixer: Two separate buses provide independent automixes
for each mix output. In this setting, two entirely different mixes can
result from the same set of inputs.
Enable dual mixer operation by pressing the Dual Mixer button on the
back panel or from GUI > IntelliMix Tab .
Example Dual Mixer Applications:
• Set Mix A to Classic mode for sound reinforcement, and set Mix B
to Smooth for a broadcast feed.
• Mix A to Classic mode for sound reinforcement, and Mix B for
Manual for recording.
• Route channels 1-4 to Mix A and 5-8 to Mix B to run independent
automixes for two different locations from one device.

Custom
Custom mode allows IntelliMix parameters to be fine-tuned and tailored from
the GUI. 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. Custom configurations can also be saved as a file to a computer
and loaded onto the device for quick recall.
