Architects Specification, Guarantee | Shure 515SBG, 15SB-GI8

Important: Shure microphone cables are selected after exhaustive tests to insure superior performance in microphones because of low capacities, superior shielding properties and unusually long life under severe use.

Cables with plastic insulation should not be sub- jected to excessive soldering-iron heat. Carefully clean and tin the conductors and the connections to which the conductors are to be soldered. The soldering operation can then be done with a minimum of heat, thereby avoiding any possibility of damage to the cable.

ARCHITECTS' SPECIFICATION

The microphone shall be the Shure Model 515SBG, 515SB-GI8 or equivalent. The microphone shall be a moving coil (dynamic) microphone with a 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 cancella- tion at the rear shall be 15 to 20 dB. The microphone shall be low impedance with a rated impedance of 150 ohms for connection to microphone inputs rated at 19 to 300 ohms. The microphone output shall be

-60 dB where 0 dB = 1 milliwatt with 10 microbars. The microphone shall be equipped with a built-in, non- locking, push-to-talk switch.

The Model 515SBG shall be suitable for mounting on

agooseneck having a %"-27 thread. The microphone shall have a 1.8m (70 in.) four-conductor (two shielded) cable. The overall microphone dimensions shall be 159 mm (6-1/4 in.) in length and 37.3 mm (1-15/32 in.) in diameter.

The Model 515SB-GI8 shall be mounted on a flexible gooseneck having a mounting flange. The microphone shall have a 1.3m (51 in.) four-conductor (two shielded) cable extending from the gooseneck. The overall di- mensions shall be 635 mm (25 in.) in length and 37.3 mm (1-15/32 in.) in diameter.
