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 af-
fecting 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 exter-
nal relay or control circuit. Refer to the following table and to the 
wiring diagram in Figure 4.

INTERNAL CONNECTIONS

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.

Mount the 515SBGX onto a gooseneck or fixed pipe with a 5/8 in-
27 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.
