The MR3eq brings the equalizer of the Harrison MR3 console to the 500 Series format. It is an analog design with three bands, each with up to 10 dB of boost or cut, and a separate high-pass filter. The EQ and filter sections each have their own In switch, so either can be bypassed independently.
The high-frequency band is a 6 dB/octave shelf covering 800 Hz to 15 kHz, and it can be switched to a second-order bell response with proportional Q. The mid band covers 400 Hz to 8 kHz and has a continuously variable, proportional Q. The high-pass filter is specified by its 3 dB corner frequency. An input overload LED shows when the signal level is too high.
The module fits any chassis that accepts 500 Series format modules, including Harrison's own D510 ten-slot rack. A user guide is available for download.
