Astatic WM625S Wall Mounted Omnidirectional Dynamic Microphone

Wall Mounted Microphone Designed for Intercom and Paging Applications

The Astatic WM625S is a rugged wall-mounted dynamic microphone engineered specifically for intercom, paging, and P.A. systems in commercial or industrial environments. Designed to mount directly into a standard duplex wall outlet box, this microphone delivers dependable performance in high-traffic or public communication zones. With its integrated push-to-talk switch, it allows users to control transmission with precision, making it a practical solution for voice-driven operations in security, retail, and institutional settings.

Durable Design for Fixed Wall Installations

Built for flush mounting, the WM625S installs into a standard duplex electrical wall box, providing a clean, professional look in any fixed-location setup. This installation style is ideal for areas where handheld microphones would be impractical or susceptible to damage. Whether installed in control rooms, hallways, schools, or access points, the WM625S offers a secure and unobtrusive audio capture solution.

Push-to-Talk Function Simplifies Communication Control

This microphone features a double-pole, double-throw (DPDT) push-to-operate switch that gives the user complete control over when audio is transmitted. This is especially useful in intercom systems where precise control over mic activation is required to avoid unintended broadcast. The tactile feedback of the switch ensures reliable user interaction during fast-paced or noisy environments.

Clear Audio with Omnidirectional Pickup Pattern

The built-in omnidirectional dynamic capsule captures sound evenly from all directions, offering forgiving pickup performance no matter where the user is positioned. This is especially useful in wall-mounted installations where the speaker may not be directly in front of the microphone. The result is intelligible, consistent audio reproduction for efficient communication.

Low Impedance Output Supports Long Cable Runs

With its low impedance output, the WM625S is capable of driving audio signals across long cable runs without degradation in sound quality. This makes it ideal for installations where the microphone is far from the amplifier, mixer, or central control system. Its stripped and tined cable ends allow for simple and secure hardwired connections during installation.

Built to Withstand Challenging Environments

The WM625S is designed with durability in mind, capable of operating reliably in locations exposed to varying temperature and humidity levels. Its robust construction ensures it holds up in both indoor and semi-exposed applications where environmental stability is a concern. The microphone’s passive operation also eliminates the need for phantom power or external power supplies.
