GENERAL
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 patter
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).
Features
• Frequency response optimized for announcing, narration, and
paging applications
• Cardioid pickup pattern symmetrical about axis
• Neodymium magnet for high signal-to-noise ratio
• Shock-mounted cartridge for quiet operation and low stand/handling noise
• Tough diecast locking grille and handle
• Built-in push-to-talk button controls microphone circuit and relay
or control circuit
• 45.7 cm (18 in.) gooseneck and mounting flange supplied
(515SBG-18X and 515SBG-18XF only)

MOUNTING THE 515SBG-18X AND 515SBG-18XF
Mount the 515SBG-18X or 515SBG-18XF as follows:
1. Thread the supplied hexnut all the way down on the mounting
flange.
2. Thread the gooseneck tightly on the flange.
3. Back the hexnut up against the gooseneck, and use a wrench
to tighten the nut firmly against the bottom of the gooseneck.

MOUNTING THE 515SBX ONTO A GOOSENECK
REPLACEMENT PARTS
Mount the 515SBGX onto a gooseneck or fixed pipe with a 5/8 in27 thread as follows:
1. Unscrew the black end cap from the microphone.
2. Remove the thin metal washer and the metal spacer.
3. Re-install the washer by sliding it back onto the cable and up
into the end of the microphone.
4. Slip the cable into the gooseneck or pipe and thread the
microphone firmly to the mount.

CONNECTIONS
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.
