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 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).

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.
The GREEN and WHITE cable leads are used to control an exter­nal relay or control circuit. Refer to the following table and to the wiring diagram in Figure 4.

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
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.
