SPECIAL Close Out Pricing, Limited Quantities!! The 531E is a purist’s dream - audiophile sound quality, an uncluttered control surface, and rugged reliability in one package. It offers thirty-one filter bandson 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, a12dB per octave High Cut and Low Cut filters is provided. Each has a sweepable cutoff frequency and a control range that extends well into the sub/ultrasonic.
