The AM/CHA1 from Black Lion Audio is a dual-channel inductor-based 15 band EQ. It is musical and very natural sounding, mainly due to the state-variable filter, custom wound Cinemag inductors, and grain oriented silicon steel transformers. The resulting audio has smooth highs, natural mids, and thick, powerful bass.

15 Bands of Adjustable Boost/Cut
The AM/CHA1 features adjustable boost and cut at 65Hz, 115Hz, 290Hz, 205Hz, 500Hz, 840Hz, 1.76kHz, 560Hz, 1.2kHz, 3.1kHz, 6.1kHz, 2.4kHz, 3.7kHz, 8.2kHz, and 15.6kHz. Each band also features variable Q to add to the flexibility of the applications along with a selectable peak or shelf for low and high frequencies.
Inductor Based Circuitry
The Inductor based circuitry lends itself to a wonderful natural and musical quality that gyrator circuits cannot achieve. This design also gives the AM/CHA1 a desirable vintage character which includes smooth highs, natural mids, and thick, powerful bass.
