The Clear-Com Tempest900 4-Channel BaseStation is a professional wireless intercom system core operating in the 900 MHz frequency band, designed to deliver reliable, license-free communication for live events, broadcast, and theatrical productions. This base unit serves as the central hub, housing four independent transceiver channels that communicate with compatible Tempest wireless beltpacks and headsets. Operating in the 900 MHz ISM band offers advantages in certain environments, such as better penetration through walls and obstacles compared to 2.4 GHz systems, and less congestion from Wi-Fi networks, making it a robust choice for challenging RF landscapes like concrete buildings, stadiums, or dense urban event spaces.

The base station is engineered for flexible deployment, capable of operating as a standalone wireless system or integrating seamlessly with existing wired partyline and digital matrix intercoms via standard interfaces. Each of its four channels supports full-duplex audio, allowing natural, simultaneous conversation for wireless users. The unit features comprehensive controls and status indicators on its front panel for channel configuration, volume adjustment, and RF signal monitoring. System configuration and advanced management, including frequency coordination and user assignment, are typically handled through intuitive software on a connected computer, allowing for precise optimization of the wireless network to avoid interference.

Designed for reliability in professional settings, the CM-944 Tempest900 Base Station often includes features like dual redundant power supplies and remote antenna connectivity. The ability to connect remote antennas via coaxial cable allows system designers to position antennas strategically for optimal coverage across large or complex venues. By providing four channels of clear, low-latency wireless communication with the propagation benefits of the 900 MHz band, this base station empowers production teams to grant key personnel—such as directors, stage managers, and roaming camera operators—reliable mobility without being tethered by cables, ensuring seamless coordination even in acoustically and electromagnetically challenging environments.
