Overview
The BP28 from Audio-Technica is a 14" shotgun microphone that combines the directional characteristics of shotgun microphones with a highly sensitive, large-diaphragm condenser mic capsule that delivers accurate and natural sounding speech and dialog. The BP28's high directivity, low noise, and transparent audio reproduction make it well suited to broadcast, video, feature film, and theater applications.
The BP28 sports a 28mm diameter body to accommodate the large capsule, but manages to keep the interference tube relatively short; in addition, the mic incorporates a directional (gradient) element into the tube to further reduce pickup from the rear. Lightweight, yet durable, aluminum housing means the mic is still relatively easy to position and handle on a boom during active productions.
