Audio-Technica BP28L Large-diaphragm Line + Gradient Microphone, 22" long

Product Overview

The Audio-Technica BP28L is a large-diaphragm line + gradient condenser shotgun microphone built for long-reach, low-noise pickup in broadcast, film, and theater sound. Its 22.4″ interference-tube body delivers an extremely tight, highly directional pattern that isolates a subject from surrounding noise. This professional shotgun microphone pairs a large-diaphragm element with a patented acoustic port design that keeps directionality consistent across the frequency range.

Product Description

The Audio-Technica BP28L is a large-diaphragm line + gradient condenser microphone engineered for demanding broadcast, film, and live-production audio. The 28 mm large-diaphragm element gives it exceptionally low self-noise for a shotgun, so distant or quiet sources are captured cleanly. At 569 mm (22.4″) long, the BP28L offers the tightest reach in the line for sideline sports, stage, and field work.

A patented acoustic port design maintains the tight polar pattern across the entire frequency range, while transformer-coupled output and a wide 11V–52V phantom power range suit a variety of broadcast and field rigs. Switchable 80 Hz high-pass and 10 dB pad let it handle wind rumble and high-SPL sources without added accessories.
