The mic capsule is small enough to ensure phase coherency up to the highest frequencies in the audible spectrum, resulting in a wide, smooth frequency response free of phase interference. Clarity and reach are also enhanced.

•The FLAT position provides a flat
•The CUT position rolls off the bass, useful in noisy or boomy surroundings.
•The BOOST position boosts the bass for a more natural sound when the mic is used on a small surface such as a lectern.
