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
All three models are supplied with a push-to-talk button and a
four-conductor cable (two conductors shielded).
Frequency response optimized for announcing, narration, and
