Product Description This conference unit features a square metal short microphone boom with high sensitivity. It is equipped with a metal oxidized panel for a simple and robust appearance. The microphone capsule uses rubber shock‑absorbing material to minimize desktop noise interference during audio pickup.

In addition to normal speech management, the conference unit supports image display and service call functions.
