Chapter 15: Graphic Equaliser (GEQ)
This chapter describes the internal GEQs of the PRO Series. Initially, it explains how to
use the PRO Series Control Centre to configure and operate the GEQs and then details
all of their available control functions.
Overview of the GEQs
The PRO Series Control Centre incorporates a graphic equaliser (GEQ), which is closely
based on the Klark Teknik DN370 Graphic Equaliser (see Appendix C “Klark Teknik
DN370 GEQ” for details). You can configure the PRO Series Control Centre to have set
numbers of these GEQs up to a maximum of 28 (PRO3) or 36 (PRO6 and PRO9), and
these are mutually inclusive of the number of effects you can have. For example, on a
PRO6 and PRO9 you can have two effects and 32 GEQs, but if you want six effects you
can only have 16 GEQs.
Each GEQ is a single-channel, 31-band, third octave graphic equaliser, and GEQ
features switched 2nd order treble and bass filters and two notch filters with variable
frequency ranges.
The GEQ is primarily a mono process, but in the case of stereo groups or mix channel
outputs, a stereo GEQ is controlled from a single set of controls.
You can control the GEQs remotely using the Klark Teknik DN9331 Rapide Graphic
Controller.
The GEQs are managed via a virtual eight-unit rack on the Graphic EQs screen. From
here you can open the window of any GEQ, which gives you full control over it.
