EGARDLESS OF THE SIZE OF YOUR SOUND SYSTEM, good equalization is vital to its
performance. That is why we developed the 531E and 532E Graphic Equalizers - as high
quality alternatives to the mediocre “affordable” equalizers available today.

APPLICATIONS
Sound Reinforcement
Installed Sound Systems
In fact, the 531E and 532E are a purist’s dream
- audiophile sound quality, an uncluttered
control surface, and rugged reliability in one
package. They offer thirty-one filter bands per
channel on ISO 1/3rd-octave centers. Through
the use of a global range switch, each band
delivers either +/- 6dB or +/- 12dB of cut or
boost. The grounded center detent position on
each band serves as an on/off switch that
completely removes that band from the audio
signal path. In addition, they sport 12dB per
octave High Cut and Low Cut filters. Each has
a sweepable cutoff frequency and a control
range that extends well into the sub/ultrasonic.
Of course, the features and controls are
secondary to the all-important question: How
does it sound? Our design team believes that
no one should have to settle for “good
enough”, so they threw out all the conventional
circuit designs and started from scratch. The
result: a highly advanced filter topology that
delivers extremely low distortion and noise,
even at very high signal levels. Consider the
following facts. Our proprietary filter technology delivers an extremely low noise floor,
ultra-accurate summing, and minimal ringing
and phase shift. The total harmonic distortion
is less than 0.002%. Translation: the 531E and
532E are clean, clear, and musical-sounding.
To ensure the highest level of performance, we
build the 531E/32E to touring standards.
Double sided, glass epoxy circuit boards; metal
shaft, plastic film slide potentiometers; goldplated XLR connectors, and a heavy duty allsteel chassis deliver rugged reliability. You
don’t have to treat these EQs with kid gloves.
The details are worth noting, too. Highcontrast front panel graphics make your
control settings easy-to-read - even in a
darkened concert hall. Servo-balanced outputs
remove all DC offset voltage from the output.
This eliminates the need for DC blocking
capacitors in the signal path while improving
noise, distortion, and low-frequency performance. Of course, both units incorporate a
high current, internal power supply with an
IEC-type detachable power cord.
Whether you are a professional concert sound
engineer, system designer, or musician, contact
your nearest Symetrix dealer today. Discover
for yourself why the 531E and 532E are the
right choice for any professional sound
reinforcement application. •
