NTI EQ3 Equalizer "air band" original in great condition. Designed to equalize without adding noticeable phase distortion, the NTI EQ3 was a TEC award nominee in 1995 in the Signal Processing Technology category.  Originally designed by Cliff Maag, who has gone on to found Maag Audio, the NTI EQ3 was his original Air band EQ, and many feel, his best.Its six bands of EQ include a 'sub' band that works around 10hz, to control the superlow frequencies, as well as 40 hz, 160hz, 650 hz, 2.5 KHz, and their famous 'Air' band for the upper nearly-inaudible registers.All bands are about two octaves wide, and overlap each other. With both coarse (3db) and fine (1/4 db) detented controls, the EQ3 gives you all the control you need, while making your settings easy to remember. Very nice on the two-buss.A great multi-purpose EQ, sometime compared to the GML parametric EQ, many use them on the stereo buss or for mastering. This unit is great condition, only light studio use and carefully stored the last couple years.    Local pickup available in Nashville, TN.
