6.4.2 Duck Priority Function
(Figure 6.9) “Ducking” is the attenuation of an input when another input with a
higher priority is activated by the
Gate function. When the higher priority gate opens, all inputs with lower priorities drop to their Low Set values. To
activate the Duck Priority function, turn it on and set the priority level.
IMPORTANT: The Duck Priority function is dependent on the Gate function. Both the Gate function and the
Duck Priority function must be on for Ducking to function.
Duck Priority: The Duck Priority function is turned on and off with this control.
Level: The Level control determines which input takes precedence. The priority can be set from 1 to 6 with 1
as the highest priority and 6 as the lowest. A separate priority level setting is provided for each channel, making
it possible to give an input a different priority for each output channel. The Level setting is ignored if either the Duck
Priority or Gate controls are turned off.
If only two inputs are used, there only needs to be two priority levels (perhaps 1 and 2). If you are unsure how
many priority levels will be needed or what the final priorities will be, start with levels 3 and 4. The priorities above
and below remain available for assignment to other inputs. If several SMX-6 mixers will be linked in a Crown Local
Net, they will be able to share Duck Priority information with other SMX-6 mixers. If this is the case, you will also
need to consider the input priorities of the other SMX-6 mixers.
Tip: When a signal ducks, the gain drops to the Low Set level for that input. The default value is off (–100 dB).
This may sound too abrupt because it is such a large transition. To avoid this problem, pick a higher value for a
more smooth transition. The Low Set control can be set so high that the ducked signal is still audible over
background noise. This may be desirable when mixing a debate or conference.
Note: The Delay Time control of the Gate function also affects the Duck Priority function. When a high-priority
input falls below its gate Threshold, all ducked inputs must remain at their Low Set levels until
after the Delay
Time.
Duck priorities can be shared by more than one SMX-6 if they are connected to a Crown Local Net. See Section
6.4.7 for more information.
The following list shows the possible settings for each Duck Priority function control.
Duck Priority: On/Off
Level: 1, 2, 3, 4, 5, 6
