Polycom Expansion Microphone – Technology Bazar

The Polycom Expansion Microphone is built to enhance audio pickup in meeting rooms by extending the voice coverage of a Polycom conferencing system. It is typically used with video bars or conference phones to capture voices from across larger tables or in bigger rooms.

Equipped with a three-mic array arranged for full 360° audio capture, it works to ensure that all voices, even those farther away, are picked up with clarity. The mic module intelligently levels voices and suppresses background distractions so that meeting participants sound natural and clear. A convenient mute button on the microphone allows users to silence it when needed, giving more control during sessions.

This expansion microphone connects via a cable (often RJ11 or equivalent) to the main conferencing unit. It’s compact, easy to place on a table, and integrates smoothly into the system’s audio processing, providing a seamless extension of its built-in audio coverage. The expansion mic is ideal for organizations needing to improve clarity in medium to large rooms without replacing the entire conferencing system.
