Dante

Lockout and Reset

Noise Adaptive Threshold (NAT)

Continually adjusts the gate threshold for opening a channel.

Number of Open Microphones Attenuation (NOMA)
Determines the ideal gain attenuation for a mix output as
additional channels are opened.

Last Mic Lock-On (LMLO)
Keeps the most recently activated microphone open
until another microphone is activated.

MaxBus

Ensures that only one channel is opened per sound source,
reducing comb ltering for clear, intelligible speech.

Modes

Tailored Automix Style Presets

Classic

Ideal for noisy environments, such as live sound reinforcement,
classic mode uses fast-acting, seamless channel gating and
consistent perceived ambient sound levels.

Networked Solutions

Networking options available with the SCM820 enable advanced
control and signal routing. Link multiple units together on a
network, then control their settings and signal path remotely
from a PC or Mac.

Standard Ethernet or Dante Digital Audio

Choose the best networking option for the application.

Dante Upgrade Card

Upgrade standard Ethernet models
to add Dante digital audio.

Dante Virtual Soundcard

License included with Dante-equipped models and upgrade card
allows a computer to connect to a Dante network for use with
playback, recording, and internet calling software.

Linking Mixers

Dante-equipped SCM820 mixers can be linked to form large
automixes of up to 12 units (96 channels of audio).

Control System Compatible

Connects to AMX and Crestron controllers.

Smooth

Ideal for quiet environments, such as broadcast or recording
applications, smooth mode dynamically balances system gain
between open and closed channels.

Extreme

A more aggressive form of classic mode, extreme mode
is congured to achieve maximum gain before feedback by
completely attenuating closed channels.

Manual

Deactivates IntelliMix to allow the SCM820 to operate as
a standard mixer.

Custom

Allows customized IntelliMix settings to be saved to a computer
and quickly loaded onto the device.
