The MOTORCITY EQualizer is a completely analog, passive EQ design with seven accessible frequency points across the tonal spectrum. Each frequency has a stepped rotary switch capable of a flat response, or up or down up  8db in 1dB increments. Frequency points graduate from 50hz, 130hz, 320hz and 800hz before jumping to 2000hz, 5000hz, peaking at 12,500hz. The front panel also features a simple in/out/off toggle switch with top hat knob and jewel light power indicator. All rotary switches have easy to read from a distance “General Radio” bakelite style knobs recreated to look exactly like the originals (remember, this is not a slider-style graphic EQ). Finally, it features a master gain control (-8db/+8db) , again in 1dB increments. The incredibly simple 1960’s accurate back panel features a power supply jack, and an XLR input and output. The sound itself is exactly what you’d expect. It packs a punch without sounding harsh or distorted. While something as simple as an analog seven band EQ might sound more like hype than hyper goodness, hearing is believing. Why has Heritage audio gone through the seemingly impossible task of bringing them back to life? Michael Brauer will tell you this: It simply got that sound! The Heritage audio MOTORCITY EQ is not a digital equivalent, not a respectfully close replica and not a more compatible modernized “improvement.” The MOTORCITY EQualizer is nothing more or less than the genuine article finally made available for the general public..
