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.
