8.15. Ducker Settings
The ducker function is one of the D-901's auto-mixing functions, and automatically adjusts individual input
channel gains in response to input signal level. Refer to the previous page for the block diagram of the Auto-
Mixing section.
When a received signal exceeds the gate threshold level, the ducker function automatically attenuates all
other input signals which are lower than that input channel in priority.
This function operates in individual auto-mixing groups (previous page).
