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
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, permit­ting 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.

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-years warranty

MOUNTING

To mount the microphone on a gooseneck or fixed pipe with a

5-8 in. 27 mounting thread, proceed as follows:

1. Use the supplied hex wrench to loosen the setscrew enough
so that the end cap can be unscrewed from the microphone.

2. Remove the end cap from the microphone.

3. Remove the thin metal washer and the metal spacer.

4. Replace the washer by sliding it on to the cable and up into the
end of the microphone.

5. Slip the cable through the gooseneck or pipe.

6. Thread the microphone firmly onto the end of the gooseneck
or pipe.

7. Tighten the setscrew to prevent the microphone from loosen­ing.
