Pro broadcast 395mm line + gradient mic. 48v phantom

$1,395 + shipping (includes gst)


With directivity equal to mics up to 50% longer, the BP4071 has been specially created to meet the pickup demands of broadcasting, film/TV sound, professional recording, wildlife recording and theater sound reinforcement. Particularly useful for miking dynamic action in film/TV audio as well as in ‘spot’ miking techniques in the music studio or theater, the 15.55″-long BP4071 provides a low noise floor and direct-coupled, balanced output for a clean signal even in high-output conditions. Audio-Technica has pioneered an interference tube design in the BP4071 that provides the same directivity as mics up to 50 percent longer.
