EQUALIZERS
The Studio 400 has a broad selection of equalizer Modules to cover virtually any need. Both mono and
stereo modules are available. Remember that mono equalizers connected to stereo sources will always
sum the stereo signal together for equalization (thus eliminating the stereo image). If you need to maintain
the stereo image, use a stereo equalizer module.
The Parametrics allow you to cover very specific regions of the sound spectrum with extreme precision
and control. Up to 6 bands of either stereo, or mono parametric equalization are available.
The Graphic equalizers use 1/3, 2/3, or 1 2/3 octave ISO-standard frequency centers.
PARAM. DESCRIPTION
Level Controls the signal input level fed to the Module. Varies from OFF to 100%.
Phase Inverts the phase of the source signal. Can be set either IN or OUT of phase.
Phase L - R Inverts the phase of the left or right side of the stereo source signal. Can be set
either IN or OUT of phase.
(Freq) Hz Controls the amount of boost / cut applied to the selected frequency. The GEQ8
uses 1-1/3 octave ISO standard frequency centers, while the GEQ15 and GEQ31
use 2/3 octave and 1/3 octave frequencies. Boost / cut range for each band is
from -12 to 12.
LoShlv Freq Controls the center frequency of the low-frequency shelving EQ band. Ranges from
25 Hz to 20 kHz.
LoShlv Level Adjusts the amount of boost or cut applied to the frequency selected by
LOSHLV FREQ. Varies from -12 to 12.
Band# Freq Sets the center frequency of the selected band. 6-band PEQs have four true
parametric bands of EQ plus shelving high- and low-frequency controls with variable
frequency. Bands 1 and 2 range from 25 Hz to 20 kHz. Bands 3 and 4 range
from 1 kHz to 20 kHz.
Band# Width Controls the bandwidth of the selected frequency. The higher the setting of WIDTH,
the more frequency-selective the boost / cut becomes. In other words, with low
(narrow) WIDTH settings, frequencies around the seleced center frequency are not
affected by the LEVEL setting. As WIDTH increases, frequencies around the center
frequency become affected by the setting of LEVEL.
Adjusts the amount of boost or cut applied to the selected frequency.
Band# Level
Varies from -12 to 12
HiShlv Freq Controls the center frequency of the high-frequency shelving EQ band.
Ranges from 1 kHz to 20 kHz.
HiShlv Level Adjusts the amount of boost or cut applied to the frequency selected by
HISHLV FREQ. Varies from -12 to 12
