The Buzz Audio REQ2.2 ME is the mastering version of the REQ 2.2 passive EQ delivering impressive sound with no harshness, tight low end and clear high frequencies.
The Buzz Audio REQ2.2ME features a unique combination of parallel passive filter circuits and active amplifier stages. Unlike the regular REQ2.2, the mastering edition includes +/- 8dB stepped boost and cut controls for each band via 23 position ELMA brand switches and different high pass filter slopes with smaller steps.
The REQ2.2 ME is truly unique in that it features no less than 72 central frequencies spread over all four bands of each channel offering far more flexibility than most passive EQs. The lower and higher bands can be switched to shelves or bells depending on the application and both mid frequency bands cover different frequency ranges. When in Shelf mode, the Q or bandwidth control can be used to control the slope of the shelves.
The Buzz Audio REQ 2.2ME also features a variable “saturation” module based around a steel transformer driven by an old style Class A amplifier, producing a “vintage” style sound. When the saturation is engaged, the low-frequency response is affected by the saturation control depending on the position of the switch.
The Buzz Audio REQ2.2ME displays superior craftsmanship throughout with high quality all-stepped controls for precise matching and recall, clever modular design for easy servicing, single point power supply wiring and discrete power regulator for each band.
