The Shure Models 515SBGX, 515SBG-18X, and 515SBG-18XF microphones are low-impedance dynamic microphones designed to be mounted on flexible goosenecks or fixed pips. Optimized frequency response and a unidirectional (cardioid) pickup pattern makes them ideal for language labs, paging applications, and base station communications. They are also recommended for use as talkback or cuing microphones in TV, film, and recording studios. Because of their low impedance, these microphones retain their level and response characteristics even when long lengths of cable are used.
All three models are supplied with a push-to-talk button and a four-conductor cable (two conductors shielded).
Model 515SBGX: Does not include gooseneck or mounting flange.
Model 515SBG-18X: Includes gooseneck and 76.2 mm (3 in.) diameter mounting flange.
Model 515SBG-18XF: Includes gooseneck and 44.4 mm (1-3/4 in.) diameter mounting flange.
Mount the 515SBG-18X or 515SBG-18XF as follows:
Mount the 515SBGX onto a gooseneck or fixed pipe with a 5/8 in- 27 thread as follows:

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 RED and BLACK cable leads are the microphone conductors for balanced-line connections; the shield is connected to the amplifier ground.
For unbalanced operation, connect the BLACK lead to the shield, and use the RED lead as the microphone conductor.
The GREEN and WHITE cable leads are used to control an external relay or control circuit.
