Product Description

The Shure 515SBGX microphone is low-impedance dynamic microphone designed to be mounted on flexible goosenecks or fixed pips. Optimized frequency response and a unidirectional (cardioid) pickup pattern makes ideal for language labs, paging applications, and base station communications. The microphone is alsorecommended for use as talkback or cuing microphones in TV, film, and recording studios.

Because of its low impedance, the microphone retains its level and response characteristics even when long lengths of cable are used. The microphone is supplied with a push-to-talk button and a four-conductor cable (two conductors shielded).


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.
