example mics 3 and 4 are the ducking targets of mic 2.
Any signal on input #2 that exceeds the ducking threshold now ducks mics 3 and 4.
The ducking targets can be changed at any time by double-clicking the mic 2 ducking
processor block.
Since mic 2 is a target of mic 1, if a signal on mic 1 exceeds the ducking threshold,
mics 2 through 4 are still ducked regardless of whether the signal on mic 2 exceeds its
ducking threshold.
NOTE: No input will be ducked more than the amount set in the applicable
by (dB):

Automix Tutorial

An automixer manages multiple microphone sources, gating or varying input gain
automatically. When properly set, the automixer system improves use and performance
when multiple mics are in use. The two basic types of automixer that the DTP CrossPoint 4K
uses lets the user choose between are gated and gain-sharing.
• Gated automixer — Attenuates an input channel when the signal level drops below
a user-defined threshold. When a number of open mics (NOM) value is provided, the
automixer is gated. The DSP Configurator allows the user to divide these automixers
into gating groups. Each gating group is effectively a separate automixer.
• Gain sharing automixer — Sets a maximum room gain and splits this among all
open mics, based on their input levels. When the NOM is set to zero, the automixer is
gain-sharing. While a gain sharing mixer typically has less delay in reacting to a speaker,
gated automixers produce a better noise floor.
The automix dialog box configures the parameters of each channel and selects an AM group.
Automix Group Details
Assigning individual automix channels to groups lets you see and adjust all channels
assigned to the group on one page. The automix group dialog box (see figure 79) provides
details of all grouped and ungrouped inputs including the automix settings of each channel
or mic. This provides an overview of all channels in the selected group at a glance. Individual
settings can be changed without leaving the groups dialog box. You can also select all
