Bogen ANS501 Ambient Noise Sensor and Microphone for Paging Systems

Ensure clear, intelligible paging and background audio throughout noisy or variable environments with the Bogen ANS501 Ambient Noise Sensor and Microphone for paging systems. This pro sound masking generator class device continuously monitors ambient noise and automatically boosts page or music levels only when needed—so announcements remain audible without overdriving your system.

Designed for professional audio and security installations, the ANS501 features balanced and unbalanced inputs/outputs and supports up to four ANS500M microphone modules wired in parallel for broad area monitoring. AUX inputs (summed mono) bypass gain control for emergency overrides, while remote-defeat terminals let you integrate centralized control from security or building automation systems. At just 5.3" x 1.3" x 3" and 12 oz, it installs discreetly between preamp and power amp or at amplifier insert jacks.

Ideal for corporate, healthcare, retail and surveillance sites where reliable announcement intelligibility is critical. Add the Bogen ANS501 to your paging, security, or monitoring setup to maintain consistent communication—contact your integrator or order now to spec it into your next project.
