MODEL 515BSLX

UNIDIRECTIONAL MICROPHONE

The Shure Model 515BSLX is a dynamic (moving coil), low-im-

pedance, cardioid (unidirectional) microphone designed for mount-

ing on a gooseneck or fixed pipe with a

5/8 in.-27 thread. The

cardioid pickup pattern provides excellent voice reproduction with

effective rejection of feedback and background noise. The

515BSLX is especially suitable for use in communications, paging,

and talkback systems. The microphone is supplied with a slide

switch controlling the microphone audio and a relay circuit, permit-

ting hands-free operation. The microphone comes with a 1.8 m (6

ft) four-conductor, two conductors shielded, cable.

The 515BSLX is wired with the microphone circuit normally

open for use in parallel-wired microphone installations.
