Important Note! For numeric input double click into the parameter field. You must use the period as a
decimal separator. For graphical input use the left mouse button and drag it horizontally to change frequency
and vertical to change gain while the mouse wheel will change the Q value.
If one selects another program for EQ setting the color code changes
accordingly. If all 3 columns in the ON AIR section are activated for
processing (Equalizer = ON) you can see three graphs in the display:
Link (Program 1) [Quad / Movie / Live / Linked / Linked & LFE]
You may select one of the possible multichannel modes to enable
gang setting of the EQ parameter values.
Link (Program 2) [Linked / Unlinked]
For stereo operation you may link the setup parameters.
Equalizer [ON / OFF]
Band 1 The parametric EQ function block offers 5 bands for each
program / channel (if unlinked).
Filter Type [OFF / Peak 1 / Peak 2 / Lo Shelf / Hi Shelf / Lo Cut / Hi Cut]
Frequency (Hz) [20 … 20000]
Gain (dB) [-20.0 … 20.0]
Q [0.4 … 4.0]
Band 2 … 5 similar parameters as Band 1
The EQs offer two different peak modes :
Peak 1:
The bell curves of the Peak 1 filter
features constant quality (Q) over
gain.
Q is defined at -3dB below peak. It
does not change when altering
gain.
Peak2:
The bell curves of the Peak 2 filter
also features constant quality (Q)
over gain.
But Q is defined at 50% of gain.
Subjectively the bell curve
becomes sharper when increasing
gain, but this is only true for the
lower 6-8dB of gain.
