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- 13 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).
