The Shure Model 515BSM is a low-impedance, dynamic microphone designed for hand-held or fixed use. The 515BSM microphone features a unidirectional (cardioid) pickup pattern that provides excellent reproduction of voice and effective rejection of feedback. The 515BSM is supplied with a push-to-talk switch and a four-conductor, retractable cable (2 shielded conductor).
The 515BSM microphone is especially suitable for use in paging systems, public speaking, stage performance, and public address systems. It is also highly recommended for other applications requiring both hand-held and fixed installation operations and is wired with the microphone circuit normally open for use in parallel microphone installations.
