Shure 515BSM Manuals

MODEL 515BSM UNIDIRECTIONAL DYNAMIC MICROPHONE The Shure Model 515BSM is a low-impedance, dynamic microphone designed for hand-held or fixed use. The unidirectional (cardioid) pickup pattern provides excel- lent reproduction of voice and effective rejection of feed- back. The microphones are supplied with a push-to-talk switch and a four-conductor, retractable cable (2 shielded conductor). These microphones are especially suitable for use in paging systems, public speaking, stage performance, and public address systems. They are also highly recom- mended for other applications requiring both hand-held and fixed installation operations. The microphones are wired with the microphone circuit normally open for use in parallel microphone installations. Features • Frequency response optimized for announcing, narra- tion, and paging applications • Cardioid pickup pattern: symmetrical about axis • Neodymium magnet for high signal-to-noise ratio • Shock-mounted cartridge for quiet operation and low stand/handling noise • Tough diecast, locking grille and handle resist wear from constant use and handling • Built-in push-to-talk switch controls both microphone circuit and relay or control circuit SPECIFICATIONS Type Dynamic (moving coil) Frequency Response 80 to 15,000 Hz (see Figure 1) .6 m (2 ft) 1 cm (3/8 in.) TYPICAL FREQUENCY RESPONSE FIGURE 1 Polar Pattern Cardioid (unidirectional). Effective rejection of sound at rear of microphone is uniform at all frequencies, while front pickup characteristics are uniform about axis (see Figure 2). 150o 120o 150o 120o 180o 30o 60o 90o 30o 60o 90o –5 dB –10 dB –15 dB –20 dB 0 10000 Hz 6400 Hz 2500 Hz 150o 120o 150o 120o 180o 30o 60o 90o 30o 60o 90o –5 dB –10 dB –15 dB –20 dB 0 1000 Hz 500 Hz 250 Hz TYPICAL POLAR PATTERN FIGURE 2 Impedance 150 Ω rated (180 Ω actual) Output Level (at 1,000 Hz) Open Circuit Voltage*: –57.0 dBV/Pa* (0.14 mV) *1 Pa=94 dB SPL Model 515BSM User Guide 27E3088 (Rev. 4) ©2005, Shure Incorporated Printed in U.S.A. 2 Switch Built-in, leaf-type, non-locking, push-to-talk Shock Mount Internal rubber vibration isolator Cable Highly durable, retractable cable with effective hum shielding, four conductors (two shielded), neoprene jacketed with 5-pin connector Length: 330 mm (13 in.) retracted 1.83 m (6 ft) extended Case Silver finish die casting with black enamel diecast grille and stainless steel screen Dimensions See Figure 3 1.5 in. 3.75 cm 6.5 in. 16.5 cm 0.85 in. 2 cm OVERALL DIMENSIONS FIGURE 3 Certification Conforms to European Union directives, eligible to bear CE marking; meets European Union EMC Immunity Re- quirements (EN 50 082–1, 1992). CONNECTIONS These low-impedance microphones are designed for connection to microphone inputs rated at 75 to 300 ohms. Using balanced-line low-impedance cables permits very long cable lengths without affecting response or level. The GREEN and WHITE cable leads are the microphone con- ductors for balanced-line connections; the shield is con- nected to the amplifier ground. For unbalanced operation, connect the WHITE lead to the shield, and use the GREEN lead as the microphone conductor. The RED and BLACK cable leads are used to control an external relay or control circuit. Refer to the following tables and to the wiring diagram in Figure 4.

To mount the 515BSM to a wall or lectern, install a Shure A12B mounting flange, screw a Shure A25C swivel adapter to the mounting flange, then insert the microhpne in the adapter.
