That is why we

4、developed the 531E and 532E Graphic Equalizers - as high quality alternatives to the mediocre “affordable” equalizers available today.

5、t) Direct coupled inputs and outputs (superb low frequency response) Internal power supply with detachable cord In fact, the 531E and 532E are a purists dream - audiophile sound quality, an uncluttered control surface, and rugged reliability in one package. They offer thirty-one filter bands per cha

6、nnel 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

7、 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

8、 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 technol- o

9、gy 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 tourin

10、g standards. Double sided, glass epoxy circuit boards; metal shaft, plastic film slide potentiometers; gold- plated XLR connectors, and a heavy duty all- steel chassis deliver rugged reliability. You dont have to treat these EQs with kid gloves. The details are worth noting, too. High- contrast fron

11、t 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 perfor- mance.

12、Of course, both units incorporate a high current, internal power supply with an IEC-type detachable power cord.
