Great River Electronics Releases Mastering EQ

After high praise and numerous requests to expand the existing features and recall ability of the Great River EQ-2NV two channel EQ, Great River Electronics has released the MAQ-2NV Mastering EQ. This new unit features the same Class-A inductor-based circuitry, with extended high and low frequency ranges. The MAQ-2NV also features EQ gain switches, linkable channel control, and very low frequency high pass filters.

“The new Great River MAQ-2NV is a winner,” notes engineer Lynn Fuston. “The new transformers bring a depth of stereo imaging that surpasses the original EQ-2NV. The calibrated boost/cut and additional frequencies (22K shelving is my favorite) along with lower high-pass filter settings make it a great mastering tool.”

The MAQ was developed after Great River owner and designer Dan Kennedy received feedback from many engineers in the recording community about the EQ2-NV. “I was getting requests here and there for features like reset ability because [the EQ-2NV] was being used during mastering. I figured that if I were to make a unit with detented pots, I might as well move some of the frequencies around that were more appropriate for mastering as the EQ-2NV was originally designed to be a tracking and mixing EQ.”

Each channel’s four EQ band gain switches range in 1⁄2 dB steps from 0 to +/-3dB, and 1dB steps from +/-3 to +/- 8dB, and each band has separate push button bypass switches. There are Left and Right channel bypass switches, the channel high pass filter frequencies are 15, 20, 25, 32, 40, and 50 Hz, and the Link switch sets both channels from the left channel controls for identical EQ frequencies and curves.

Fuston adds, “Bypass buttons for the individual bands is a great addition. While the EQ-2NV excels at meaty and aggressive response, the MAQ-2NV opts for finesse and depth, but without compromising the sonic delight of the original.”
