The Clear-Com Tempest 900 4-Channel Wireless Intercom Kit is a professional-grade system designed to provide reliable, license-free wireless communication for live event production, broadcast, and theatrical applications. Operating in the 900 MHz ISM band, this kit enables clear, interference-resistant audio communication between key personnel such as stage managers, camera operators, and technical directors who require mobility beyond the range of wired systems. The kit typically includes a base station that interfaces with a wired intercom matrix and multiple beltpack transceivers with headsets, creating a flexible wireless extension of the existing communication infrastructure.

This system supports four independent, full-duplex communication channels, allowing separate groups or individuals to communicate simultaneously without cross-talk. The 900 MHz frequency band offers robust performance with good penetration through walls and obstacles, which is advantageous in complex venue environments. The beltpack units provide familiar intercom controls, including channel selection, call signaling, and volume adjustment, ensuring operators can communicate effectively even in high-noise situations.

Built to Clear-Com's standards for durability and audio clarity, the Tempest 900 kit is engineered for the demanding conditions of touring and fixed installations. It offers secure, low-latency communication critical for the precise timing required in live broadcasts and events. By delivering wired intercom functionality without the physical tether, this system significantly enhances operational flexibility and crew coordination, making it an essential tool for professional production teams.
