General Description
Here’s the long and the short of it. The SEQ 30S uses
Short space-saving 20 mm sliders, while the SEQ 30L uses
Long and more precise 45 mm sliders. All other features are
identical.
The SEQ 30S and SEQ 30L are 30-band equalizers with
ultimate stereo accuracy. The single set of faders controls
both left and right channels simultaneously, maintaining true
stereo tracking and utilizing constant-Q technology. These
EQs fill the void for true stereo applications.
Both models are accurate, professional quality instruments capable of precise equalization down to a fraction of a
dB. You can expect several advantages from your constant-Q
equalizer over conventional designs: moving one slider will
not affect neighboring filters as much, so you won’t spend
time re-adjusting sliders (we call this “equalizing the equalizer”). You’ll be able to obtain better feedback control
without losing sound quality. All sliders maintain smooth,
consistent and accurate calibrated control over filter levels,
which is especially critical in low-profile equalizer designs.
Because of this, the overall EQ adjustment process is significantly easier and more effective.
An Input Level control is provided along with a Bypass
switch, enabling easy gain comparisons between equalized
and unequalized signal. +4 dBu and Overload indicators
detect both input and post-EQ levels.
Either unit interfaces easily to many types of systems. Use
the balanced XLR Inputs and Outputs, or the balanced ¼"
TRS Inputs and unbalanced ¼" TS Outputs.

Application Information
Constant-Q graphic equalizers arose from the sound
professional’s need for greater control with less interaction
than previously possible with conventional equalizers. Truth
in slider position became a requirement. The curve traced out
by the slider positions on constant-Q designs indeed represents the actual changes to the frequency response. On
conventional designs they do not.
You use a constant-Q graphic the same way you use a
conventional graphic. You just get the desired results quicker,
with far less after adjustment to the adjacent sliders. Eliminating a phenomena Rane calls “equalizing the equalizer”.
The accompanying figures dramatically show the advantages of constant-Q designs. For more in-depth information
please see the RaneNote, “Constant-Q Graphic Equalizers”
available on our website.
