3-Band Dynamic EQ
EQ Type
Two different types of Dynamic EQ can be selected:
3-Band Full-range or 2 band ParaDyn.
The Dynamic EQ enables you to shape your sound
depending on energy in the signal, or to notch out specific
level dependent problems.
Three band Dynamic EQ
Two cross-over points and three sets of parameters,
enables individual setting of Lo, Mid and Hi performance
for the dynamic EQ.
This type of Dynamic EQ is typically used as a creative tool
that shapes the entire signal but can of course also be
used for system protection. In terms of creativity this type
of EQ-ing can be compared to what Mastering engineers
often do when shaping a master-mix.
The two set Crossover points defines the three bands each
holding its own individual set of the parameters described
below.
Threshold
Range: 0 to -45dBFS
When the Input signal exceeds the Threshold value the
Dynamic EQ starts to reduce the dynamic content of the
signal according to the set Ratio in the selected band.
- Regarding headroom
The Threshold always has a headroom of 45dB, but the
range is scalable with the ADA card settings on the; Setup
page-I/O Configuration-ADA I/O Settings-ADA gain.
Example:
With the ADA gain set at +21dB with Off set at 0dB, the
Threshold setting is 21dB and down to -24dB.
Ratio
Range: Off to Infinity
Specifies the Ratio of the performed compression on the
selected band.
Example:
With a Ratio setting of 2:1 the Compressor will reduce
every 2dB above the Threshold point to only 1dB.
Attack
Range: 0.3 to 100ms
The Attack time is the time the Dynamic EQ uses to reach
the gain reduction specified by the Ratio parameter in the
selected band.
Example:
If the Input signal increases by 4dB above the set
Threshold with a Ratio set to 2:1 and the Attack time set to
20ms, the Compressor will use 20ms to reach a Gain
reduction of 2dB.
Release
Range: 20ms to 7 sec.
The fallback time. The time it takes for the Dynamic EQ to
release the attenuation of the signal in the selected band.
MakeUp
Range: 0 to12dB
Manual Make-up gain for each compression band.
Cross Over 1
Range: Off to 3.15kHz
Defines the Crossover point between the lower and middle
compression bands.
Bandwidth knob functions.
Via the menu point “GraphEQ width” in the Utility menu you
can assign which of the following three functions should be
assigned to the BANDWIDTH knob:
Frequency:
The function of the FREQUENCY knob is
duplicated to the BANDWIDTH knob.
Sweep:
Set gain and sweep this gain setting
through the frequencies using the
BANDWIDTH knob.
Width:
In Width mode the BANDWIDTH knob can
be used to increase the frequency area with
center in the selected frequency.
Mirror:
Select mirror-mode and use the
BANDWIDTH and the GAIN encoder to
mirror frequencies in O dB
Curve:
Select curve-mode and use the
BANDWIDTH encoder to select more than
one frequency. Cut and boost frequencies in
curves. +/-3dB peer 1/3 oct.
