EDITING
The two-band Parametric Dynamic EQ - Paradyn - enables
you to set two fully independent dynamic notch filters.
As with a parametric EQ filter, - set the center frequency
and bandwidth as target area, and then find a matching
Threshold and Ratio to dynamically notch out level
dependent problems in the signal.
2 band ParaDyn - Parametric EQ
For each of the two bands:
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.
Ratio
Range: Off to Inf.:1
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: 0.3ms 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 Dynamic EQ will use 20ms to reach a Gain
reduction of 2dB.
Release
Range: 20ms to Lo Shelve
The fallback time. The time it takes for the Dynamic EQ to
release the attenuation of the signal in the selected band.
Frequency
Range: 20Hz to 20kHz
Sets the Center frequency on the two bands.
BW/Curve
Range: Lo Shelve - Hi Shelve to 4
At Lo and Hi Shelve selections the EQ operates as a
Dynamic EQ. At values from 0.10 to 4.00 the Dynamic EQ
operates as Parametric EQ, and this parameter sets the
Bandwidth.
Input Drive
Range: -6 to 18dB
Level compensation in the Input of the Dynamic EQ for the
level change applied by the Parametric and Graphic EQ
sections.
EQ Type
Select between 2 band Paradyn and 3 band types.
Compare function
For optimal and easy comparing, the settings are
remembered when switching between the EQ types
and both settings are saved with presets.
CrossOver 2
Range: Off to 16kHz
Defines the Crossover point between the mid and high
compression bands. Low point is Limited by the Frequency
set by Crossover 1.
Input Drive
Range: -6 to 18dB
Level compensation in the Input of the Dynamic EQ for the
level change applied by the Parametric and Graphic EQ
sections.
EQ Type
Select between 3-Band or Paradyn.
