The Shure 515SBGX microphone is a low-impedance dynamic microphone designed to be mounted on flexible goosenecks or fixed pips. Optimized frequency response and a unidirectional (cardioid) pickup pattern makes it ideal for language labs, paging applications, and base station communications. The 515SBGX is also recommended for use as talkback or cuing microphones in TV, film, and recording studios. Because of its low impedance, the Shure 515SBGX microphone will retain its level and response characteristics even when long lengths of cable are used. The mic features a push-to-talk button and includes a four-conductor cable (two conductors shielded). Does not include gooseneck or mounting flange.
