CUEMIX FX

response corresponds to a second order shelf, still

with no overshoot. This is the same response as

conventional parametric EQs. In some situations,

this form of accurate, clean shelving can sound

harsh, especially when compared to legacy analog

EQs. To soften the results, the overshoot is

increased as Q is increased, as shown Figure 10-22

for Q values of 1.00, 2.00 and 3.00. This overshoot

region produces a boost in frequencies just above

the cutoff, which compensates in a smooth, more

pleasing fashion for the perceived drop in low

frequencies being cut.

Conversely, when shelving boost is being applied,

overshoot cuts frequencies just above the cutoff to

again compensate in a smooth and pleasing fashion

for the perceived boost in low frequencies:

Figure 10-23: Overshoot when low shelf boost is applied.

Overshoot is also applied to high shelf boost and

cut:

Figure 10-24: Overshoot when high shelf cut and boost is applied.

Overshoot tends to produce more of what one

would expect to hear when applying shelving and

is therefore considered to be more musical than

shelving without overshoot. This effect, which has

gained tremendous popularity among audio

engineers, was ﬁrst made popular in original Neve

series EQs and later in the SSL G series.

At maximum the maximum Q setting of 3.00, the

overshoot peaks at half the total boosted (or cut)

gain. For example, with a maximum gain setting of

+20dB, the loss in the overshoot region is -10 dB.

Overshoot curves are symmetrical for both cut and

boost.

Low pass and high pass ﬁlters

The Vintage EQ low and high pass ﬁlters are similar

to those found in most conventional parametric

EQs (which usually have a ﬁxed slope of 12 dB per

octave), except that Vintage EQ provides six

different slope (roll off) settings: 6, 12, 18, 24, 30

and 36 dB per octave. This control over the shape

of the “knee” gives you a great deal ﬂexibility and

control for a wide variety of applications.
