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. 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 SPECIFICATIONS Type Dynamic (moving coil) Frequency Response (Figure 1) 80 to 15,000 Hz TYPICAL FREQUENCY RESPONSE FIGURE 1 Polar Pattern (Figure 2) Cardioid (unidirectional). Effective rejection of sound at rear of microphone is uniform with frequency; front pickup characteris- tics are symmetrical about axis.

WIRING CONNECTIONS The RED and BLACK cable leads are the microphone audio conductors for balanced-line connections; the shield is connected to the amplifier ground. The GREEN and WHITE leads control an external relay or switching circuit. Refer to the following table and the wiring diagram in Figure 4. INTERNAL CONNECTIONS FIGURE 4 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 loosen- ing.
