The Sony ECM-77BMP is a miniature omnidirectional lavalier microphone designed for professional broadcast, sound reinforcement, and recording applications. The condenser element features a miniature profile allowing it to be easily concealed in performance and broadcast situations. The omnidirectional polar pattern provides even frequency and sensitivity response at the direct and off-axis sections of the microphone capsule.
The ECM-77BMP provides a wide frequency response of 40 Hz to 20 kHz for accurate reproduction of audio signal from a variety of sources. The attached 3.9' cable features a 3.5mm locking mini jack for use with WRT-805 bodypack transmitters and UWP Series beltpack transmitters such as the UTX-B1 and UTX-B03. Phantom power is supplied via the connected bodypack transmitters. The ECM-77BMP includes a windscreen and tie clip.
