EQP-1A3

EQP-1A3 PROGRAM EQUALIZER

The wide range of equalization curves provided makes it possible to boost the very low or very high frequency notes without "muddying up" the middle register instruments. Continuously variable controls permit changing the amount of equalization on sustained tones without steps in level, or noise. All controls are clickless and a key permits cutting the equalizer in and out on cue.
