Graphic EQ Edit The Graphic EQ is a 29 band 1/3-octave type ranging
from 31Hz to 20kHz with +/-12dB gain range.
In addition to the Graphic EQ an adjustable LoCut,
ranging from Off to 600Hz, is also available.
Graphic EQ Type Selector
There is big differences in behavior and response between
various industry standard analog graphic EQ's. With the
EQ Station you now have the option to select the response
type you prefer.
Using the Type Selector you can select between exact
DSP-emulations of main high-end graphic EQ types on the
live-market today.
Select between the following types:
• TC1128
• Classic960 Narrow-Q
• Classic960 Broad-Q
• Classic27
The EQ Station will mute all Outputs while shifting to
a different EQ type.
Behind the four EQ types are not only a mapping of the
bandwidth response, but also three basically different ways
of combining 29 EQ filters. The TC1128 is a parallel
construction, the Classic960 types that are a combination
of parallel and cascaded filters and finally is the Classic27
a fully cascaded filter-structure.
(Read more about the differences and the consequences
of using the various Graphic EQ types in the manual
section called: “Graphical EQ types in the EQ Station”)
Basic Operation
• The display graphics show the frequency response for
the graphic EQ and the actual settings of the 29 bands.
• Adjustment of Frequency and Gain is done with the
dedicated encoders.
• Adjustment of EQ type is done with the ADJUST wheel.
Dialing the bandwidth parameter highlights and selects
the bands left and right from the selected frequency,
enabling relative adjustment of several filters at the same
time.
Lo Cut
Range: Off to 600Hz

Bars - Curve or Bars & Curve
It is possible to view the Graphics EQ either as
• Bars (example 1)
• Curve (example 2)
• Bars & Curve (example 3)
Which of these options to use is setup in the Utility menu.
