Atlas Sound EQM131 Overview

The EQM131 1/3 Octave Graphic Equalizer from Atlas Sound will provide basic system equalization for sound masking or general public address applications. The 1 RU equalizer is easily connected to any system via rear panel balanced TRS and XLR jacks. Unbalanced RCA connections are also provided for use with -10 dBV equipment. Front panel mounted LPF/HPF and level controls are provided along with a switch for ±6 or ±12 dB operation and 31 sturdy 20mm filter slide controls.

The ISO centered 1/3 octave bandwidth-constant Q filter design minimizes interaction between filters yet is still wide enough for creation of correction curves. When used with the Atlas Sound AA120M mixer amplifier and AA-SMG sound masking module (both sold separately), the EQM131 can be used to create a 1/3 octave masking spectrum which is fed directly to the AA120M amplifier section. The page/music inputs and masking module output can then be summed without affecting the masking source spectrum equalized by the equalizer.
