Model A412B Microphone Base User Guide
GENERAL
The Shure A412B microphone base allows gooseneck micro- phones to be quickly mounted in situations where permanent in- stallation 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 mount- ing surface (see Figure 1, diagram A).
2.Place the key holes over the screw heads and push the micro- phone into position. Adjust the height of the screws as neces- sary to secure the microphone (see Figure 1, diagram B).
