The low-cut filter is switch selectable from 20-Hz to 150-Hz with slopes of either 12-dB or 24-dB per octave. Like most Crane Song products, IBIS utilizes discrete class-A circuitry and features a truly unique and adjustable "color" function that can be applied to either the entire audio path or to any individual frequency band. A fully stepped mastering version is also available.
