MOUNTING
To mount the 515BG microphone on a gooseneck having a Y8"-27 thread, unscrew black end cap from microphone (see Figure 3), remove adjacent thin metal washer and one metal spacer off terminating end of cable. Slide the thin metal washer removed previously onto cable up into end of microphone. Slip gooseneck over cable and install into end of microphone.
CONNECTIONS
The microphone is low impedance for connection to microphone inputs rated at 19 to 300 ohms.
Low impedance is recommended where long cable lengths are required or under conditions of severe hum disturbance. Connect the black and white conductors to the microphone circuit (see Figure 4). The shield is connected to the metal parts of the microphone, and should be connected to the amplifier chassis or ground terminal. For unbalanced lowimpedance operation, the shield and white lead should be connected together. The black lead is then the "hot" lead.
For use with a high-impedance amplifier, the Shure A95 Series of Line Matching Transformers are available for coupling the low-impedance line to the amplifier input.

PHASING
To test two microphones for proper phasing, connect them to an amplifier and talk or sing into them while holding them three or four inches apart. The sound from the speakers should be the same when talking into either microphone or directly between them if they are in phase with each other. If the sound drops drastically, or if a dead spot is found when talking between the two microphones, the microphones are out of phase. All microphones should be tested in this manner to insure that they are in phase with each other.
To change the phase of a low-impedance microphone at the equipment end of the cable, interchange the BLACK and WHITE cable leads where they are connected to the sound system. To change the phase in the microphone, the microphone cartridge leads must be interchanged (see Figure 4). This should be performed by your dealer, the Shure Factory Service Department, or other qualified service personnel.
ARCHITECTS'SPECIFICATIONS
The microphone shall be the Shure Model 515BG or equivalent. The microphone shall be a moving coil (dynamic) microphone with a shaped frequency response of 80 to 13,000 Hz. This unit shall have a cardioid polar characteristic. The cancellation at the sides shall be approximately 6 dB, and the cancellation at the rear shall be 15 to 20 dB. The microphone shall be low impedance for connection to microphone inputs rated at 19 to 300 ohms. The microphone rating impedance shall be 150 ohms. The microphone output shall be -60.5 dB where 0 dB = 1 milliwatt per 10 microbars.
The Model 515BG shall be suitable for mounting on a gooseneck having a %"-27 thread. The microphone shall have a 1.8m (70 in.) two-conductor shielded cable. The overall dimensions shall be 159 mm (6% in.) in length and 37.3 mm (1-15132 in.) in diameter.
