Shure A412B User Manual

GENERAL
The Shure A412B microphone base allows gooseneck
microphones to be quickly mounted in situations where
permanent installation is impractical. The angled XLR input
connector maintains a low profile, while inside the base there
is ample room for custom circuitry.
INSTALLATION
Attaching a Microphone to the Base
Insert the XLR connector on the microphone into the
female XLR connector on the top of the microphone base.
Securing the Microphone Base to a Surface (Optional)
1. Install two No. 6 wood screws, two inches apart, on the
mounting surface (see Figure 1, diagram A).
2. Place the key holes over the screw heads and push the
microphone into position. Adjust the height of the screws
as necessary to secure the microphone (see Figure 1,
diagram B).
