Biamp MicroEQ 152, Stereo Graphic EQ

 Very clean Graphic EQ from Biamp.   Here are some of the specifications from the manufacturer:

The mEQ152 and mEQ301 are professional quality single rack-space graphic equalizers providing true 2/3-octave and 1/3-octave frequency control. The use of Constant-Q technology guarantees precise room tuning with less filter interaction, better filter combining, and constant filter bandwidth at any setting. This design also produces a more accurate front panel graphic representation of the EQ 'curve', and makes equalization an easier process. Best of all, the mEQ152 and mEQ301 deliver unmatched performance at a bargain price.    The mEQ152 and mEQ301 each carry a five-year warranty.
