The Telex BTR-800 is a professional-grade, two-channel UHF base station designed to function as the central transmission hub for a variety of wireless audio systems, including intercom, IFB (interruptible foldback), and general program distribution. It operates in the globally flexible UHF spectrum, providing robust and clear audio communication to compatible wireless beltpacks and receivers. The unit is engineered for high-density frequency operation, allowing two independent channels to work simultaneously within a tight frequency range without harmful intermodulation interference, a critical feature for large-scale productions where spectrum is crowded and coordination is paramount. This makes it an indispensable tool for broadcast television, live event production, and theatrical applications where reliable, multi-channel wireless communication is essential for cueing talent and coordinating crew.

This base station excels in audio management and transmission control, offering extensive programmability for each of its two channels. Users can independently configure parameters such as RF output power, select from multiple audio companding algorithms for noise reduction, and apply adjustable tone squelch to minimize the reception of unwanted signals. The integrated LCD display and front-panel navigation provide clear access to all system settings, including real-time monitoring of RF signal strength and audio levels for each channel. The BTR-800 can accept a diverse array of audio inputs, including mic, line, and intercom party-line signals, and mix them as needed for each transmission channel, enabling complex cueing scenarios where a talent might receive a mix of director talkback and a specific program feed directly to their earpiece.

Built for reliability in mission-critical environments, the BTR-800 features a rugged 1U rack-mountable metal chassis designed for continuous operation. It includes dual redundant, hot-swappable AC power supplies to ensure uninterrupted performance, a necessity for live broadcast and events. The rear panel provides comprehensive connectivity with balanced XLR audio inputs and outputs, Ethernet for network control and monitoring, and BNC connectors for external antennas, supporting both single and diversity antenna configurations. With its combination of dual-channel density, advanced frequency management, robust build quality, and operational redundancy, the Telex BTR-800 provides a scalable and dependable foundation for professional wireless communication networks.
