Bogen BUFEX Buffer Expander

Ensure clear, reliable paging and monitoring across large installations with the Bogen BUFEX buffer expander — a pro audio controller built to simplify volume control and expand speaker networks. The BUFEX remotely attenuates speaker zones while providing output buffering for up to 150 self‑amplified speaker inputs, maintaining audio quality across extended 100V, 70V or 25V systems. A dedicated bypass function guarantees that emergency announcements override local volume settings, with a PCB trim to fine‑tune bypass level (up to 12 dB attenuation). With a 600‑ohm input impedance and 10 position settings plus off, the BUFEX delivers predictable, repeatable control for paging, public address, security audio and surveillance monitoring applications. Its compact single‑gang mount fits standard electrical boxes for easy retrofit into schools, retail, healthcare and industrial environments. Designed for installers and AV/security integrators, the Bogen BUFEX streamlines audio distribution while enhancing safety and compliance. Add BUFEX to your next paging or monitoring deployment to improve intelligibility and system scalability.
