Non-flat filter values for the current channel are graphically displayed as circular markers.
Low-pass crossover is labelled "L", high-pass crossover is labelled "H", and parametric filters are
identified by a number from 1 to 10.
The graphic allows filter parameters editing using their marker. For this, you just have to point on
the marker of the filter you want to edit, click on it and drag it in the graphic holding down the mouse
button.
The current filter marker is displayed with more intensity than others (that are displayed with
semi-transparent colours), and plays an animation with arrows to show available moving directions. A
crossover can only be dragged horizontally (Frequency parameter). High-Shelf, Low Shelf and
Parametric EQ filters can be dragged horizontally (Frequency parameter) and vertically (Gain
parameter).
For filters with a Q parameter (Parametric EQ, All-Pass order 2), Q value may also be edited
through graphic markers with the mouse wheel.
5.9.2. CHANNEL buttons
They determine which channels will simultaneously be displayed, even if only one is the current
or "active" channel (appearing in the info bar).
Each channel curve has a different colour: red for AMPCH1, blue for AMPCH2, green for
STACK1 and yellow for STACK2.
5.9.3. GRAPH buttons
They include (or exclude) input gain, crossover or parametric equalization filters algorithm effect
for the graphic.
5.9.4. Vertical range
This graphic display command selects one of two value ranges for graphic
Y-axis (gain in dB).
If the button is a down pointing arrow the gain range is +12dB – -30dB. If it is
an up pointing arrow, the gain range is +12dB – -72dB.
5.9.5. Graphic curves filling
This other command is also displayed in the graphic. It
determines if the graphic curves will be filled (solid) or not.
A black SOLID word over a white rectangle means the graphic
curve is filled. A white SOLID word over a black rectangle means the
graphic curve is outlined.
5.9.6. Info bar
The graphic display has an upper status bar giving information about:
 Current ("active") channel: its name is displayed over a corresponding colour rectangle.
 Current ("active") filter: its name is displayed near current channel name.
 Parameters: depending on the current filter, parameters names and values are displayed.
