GRAPHIC EQUALIZER
General Description
The Rane GE 130 Graphic Equalizer is a single-channel,
30-band, 1/3-octave design in a double rack-space unit, only
5 inches deep. Boost/cut range is +12/-15 dB on 45 mm filter
slider controls.
The active filter sections feature Rane’s innovative
constant-Q (constant bandwidth) design. This means the
bandwidth of each individual filter is guaranteed to be narrow
enough to prevent unwarranted interaction between filters, yet
wide enough to produce exactly the type of correction curve
demanded by even the most unusual acoustic surroundings.
This differs dramatically from conventional designs of the
past, encumbered with the unfortunate characteristic of
changing bandwidth when changing boost/cut amounts.
Front panel controls and indicators, aside from the sliders,
include an overall Level control as well as an Overload
indicator. A Bypass switch allows direct comparison between
the equalized and non-equalized signal.
The rear of the unit provides both XLR and Euroblock
terminal connectors for the fully active balanced Input and
Output. Output relays provide a brief turn-on delay, eliminating power-up thumps, and a hard-wire bypass in case of
power failure.

GRAPHIC EQUALIZER
Block Diagram
Application Information
Constant-Q graphic equalizers arose from the sound
professional’s need for greater control with less interaction
than previously possible with proportional-Q 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 proportional-Q designs they do not.
Use a constant-Q graphic the same way as a proportionalQ graphic. Desired results are achieved 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 a brief explanation of Rane’s
design philosophy please see RaneNote 101, “Constant-Q
Graphic Equalizers,” available from your Rane dealer, the
Rane web site or the factory.

Architectural Specifications
The graphic equalizer shall be of constant-Q design to
minimize interactions between adjacent bands, and contain
frequency bands located on standard ISO center frequencies.
Each band shall have a bandwidth of 1/3-octave. A boost
range of +12 dB and a cut range of -15 dB shall be provided.
A detented and positively grounded 0 dB point shall be
provided on 45 mm linear sliders with dust dams.
A rotary overall level control shall be provided with a
range from off to +6 dB of gain.
The input and output shall be active balanced designs
terminated with both XLR and Euroblock connectors. RFI
filters shall be provided. The unit shall provide a bypass
