Mesanovic MQ712 500 Series Equalizer

The Mesanovic MQ712 is a 500 Series 7-band inductor based graphic equalizer. This EQ is based on the popular 70s "swinging input" topology and features frequency points similar to many graphic equalizers of the time. The top and low bands are switchable between shelf and bell curves. The MQ712 utilizes proportional Q filters. With a total of 7 bands available with 12 dB boost/cut, this EQ is capable of producing a variety of EQ curves and the MQ712 is extremely versatile on all sources.

At the heart of the MQ712 are seven custom in-house wound inductors. The 4 lower bands use a pot-core inductor while the upper three bands utilize MPP toroidal inductors. The input is transformer balanced with a custom wound input transformer and the output is also transformer balanced with a full steel core transformer for a bit harmonic coloration. All bands feature variable potentiometers with a center detent. The op amp is Mesanovic's discrete 1991 op amp. High quality components are used throughout the MQ712 including custom potentiometers, Wima/Vishay/Nichicon capacitors, and Ritel collet knobs. The unit is entirely built in-house in the USA.
