GRAPHIC EQUALIZER
General Description
The Rane GE 215 Graphic Equalizer is a two-channel, 15band, 2/3-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 for each channel as well as
Overload indicators. Bypass switches allow direct comparison
between the equalized and non-equalized signal for each
channel.
The rear of the unit provides both XLR and Euroblock
terminal connectors for each of the fully active balanced
Inputs and Outputs. Output relays provide a brief turn-on
delay, eliminating power-up thumps, and a hard-wire bypass
in case of power failure.
• Grounded Center Detents
• Overload Indicators
• Infrasonic, Ultrasonic, and RFI Filters
• Fully Balanced Inputs and Outputs
• XLR and Euroblock Connectors
• UL/CSA/CE and 100/120/230 VAC Remote Power Supplies
