4-BAND PEQ / 10-BAND GEQ The equalizer Modules provided in the Valve FX offer superb noise
performance, and allow accurate tonal shaping of many different
types of sound sources. There is a standard 4-band parametric
equalizer with adjustable Q available in all Algorithms. The Valve FX
also features a 10-band graphic equalizer in select Algorithms. All
equalizer Modules offer silent, hyper-accurate (double-precision) for
tonal shaping.
Adjustable Q equalizers offer the ability to control the bandwidth of
the boost/cut ranges. High Q settings yield extremely narrow band-
width, where boost and cut have minimal effect on adjacent frequen-
cies of the program material. Low Q settings affect a wider number of
frequencies when the selected band is boosted or cut.
With a Q setting of 2, you can see that a large number of frequencies
are affected by boosting the center frequency. Now take a look at the
middle and lower curves in the diagram, and notice the much narrow-
er bandwidth of the curves with a Q setting of 4 and 8.
