UNIDIRECTIONAL MICROPHONE
The Shure Models 515BSLG24F and 515BSLG27F are dynam-
ic (moving coil), low-impedance, cardioid (unidirectional) micro-
phones, each threaded on a black gooseneck with a black
mounting flange. These models are especially suitable for use in
communications, paging, and talkback systems. The cardioid pick-
up pattern provides excellent voice reproduction with effective re-
jection of feedback and background noise. The slide switch sets
the microphone's audio and relay circuit on or off, and the integral
gooseneck permits hands-free operation. The attached four con-
ductor cable (two conductors shielded) extends 1.2m (4 ft.) from
the mounting flange and terminates in a female 4-pin XLR connec-
tor.
FEATURES
•Rolled-off low-frequency response combined with a
smooth high-frequency rise for clear and intelligible voice
pickup
•Symmetrical cardioid pickup pattern minimizes feedback
•Shock-mounted cartridge for quiet operation and low
stand/handling noise
•Neodymium magnet for high signal-to-noise ratio
•Heavy-duty zinc, die-cast, locking, metal grille protects
cartridge and resists wear
•Built-in slide switch controls both microphone circuit and
relay or control circuit
•Backed by the Shure 2-year warranty
