Detector Type
- This selects between peak or
average detector operation:
•
Peak Detector
- Setting the detector type
as peak means that only the peak level of
a signal is used to trigger the compressor.
Peak detect is typically used for limiter
applications where any signal level above a
certain point is undesirable. In peak detect
mode, attack and release times are both
adjustable.
•
Average Detector
- Setting the detector
type to average means that a computed
average signal level is used as the
compressor trigger instead of peak levels.
The averaging detector is more musical
and natural sounding and typically used to
"thicken" vocals. When using the average
detector, attack and release controls are
replaced with a single average rate control
which adjust the speed at which compressor
action occurs.
DCA Gain
A DCA gain block can be placed on any channel
in order to assign that channel to DCA groups
1-4. The channel's overall level to all DCA
groups, plus the level to each of the four DCA
groups is individually adjustable.
A DCA is typically set up and deployed to a
remote operator who has limited software
access but simply needs to control a zone's
overall volume via mobile device or tablet. See
section
for deploying a DCA to a remote
control operator.
Delay
Delay can be used on any
input or output channel.
Delay range is from 0-682ms.
Delay can be input by time
(ms) or by distance (ft, m), using the scroll
bar or by manually entering a numerical value.
Ambient air temperature can be entered to
automatically adjust for the speed of sound in
hotter or colder air.
