CAD/Astatic MB100 Microphone Base **SPECIAL ORDER**

The Astatic MB100 is a professional wired microphone desk base designed for use with phantom powered condenser gooseneck microphones in conference, education, corporate, and government installations. Featuring a compact, low profile form factor, the MB100 provides a clean and unobtrusive solution for tabletop and lectern mounting while delivering reliable audio performance. The integrated red/green LED status indicator provides immediate visual feedback, clearly showing when the microphone is active or muted—an essential feature for moderated meetings and formal environments.

Engineered for flexibility and ease of use, the MB100 includes a programmable talk/mute switch that can be configured for toggle, push to talk, or push to mute operation depending on system requirements. Balanced audio output via XLR connector allows seamless integration with installed sound systems, while operation from standard phantom power (DC 24–52V) eliminates the need for external power supplies. With a solid, vibration resistant construction and compatibility with a wide range of standard gooseneck microphones, the MB100 is a dependable choice for everyday installed applications where clarity and control matter most.
