Adaptive Gating
Adaptive Gating dynamically modifies the Input Gate thresholds in the auto-mix group as a function
of the ambient level in the room. The ambient level is computed as the weighted average of the closed
mic input levels. The weighted average makes it possible to compensate for mic locations with differ-
ent ambient levels. Adaptive Gating functions are described below in numbers 8, 9, 10 and 14.
8. Enable
Turns Adaptive Gating on and off for an automix group
9. Ambient Level Meter
Indicates the calculated ambient level for the automix group.
10. Group Gate Threshold Ambient Offset
Sets the amount above the calculated ambient level for the gate threshold for all inputs participating
in the automix group.
• For inputs with ambient weighting factors equal to zero or one, the actual gate threshold will be off-
set from the calculated ambient level by this amount.
• For inputs with ambient weighting factors between zero and one, the offset is expanded prior to
adding it to the calculated ambient level — the smaller the weighting factor, the larger the expansion.
Control range is from 0 to 20 dB in 0.5 dB steps.
11. Automix Group
This selects/indicates the automix group that the accompanying settings are adjusted for. There can
be different settings for different automix groups (1-32).
12. Automix Matrix Button
Pressing this button opens the Automix Matrix window (described earlier).
13. Input Buttons
This area and buttons indicate and control the following:
a. Input Number
b. Ducking Priority Number (1-8)
c. Automix Group Attached (1-32).
14. Groups
Indicates with color which groups are active, and which of the three options are enabled. Options are:
a. Gate Ducking
b. NOM (Number of Open Microphones)
c. Adaptive Gating
