Description
The BTR-800 is a UHF synthesized wireless intercom base station designed to provide full-duplex voice communications between a central base and up to four beltpacks. It operates across 470-740 MHz frequency ranges and supports frequency-agile operation for flexible channel selection. The unit is engineered for broadcast and live-event environments where reliable wireless intercom is required.
Key features include two independent audio channels allowing party-line and private-line operation, full-duplex simultaneous talk and listen capability, and selectable transmit power levels for range management. The system supports wireless talk-around and stage-announce functions and includes a backlit LCD on the base station for status monitoring. Frequency-agile beltpacks and base station operation ensure fast re-tuning and ClearScan automatic channel selection.
Technical performance includes operation in two 18 MHz TX/RX bands (470-608 MHz and 614-740 MHz), a maximum transmit power of 100 mW and a normal mode of 10 mW, and a user capacity of four beltpacks. Audio bandwidth and fidelity are sized for intercom use with a frequency response of 300 Hz to 8 kHz and local headset output rated at 40 mW into 600 ohms. The system supports FM modulation with a deviation of 40 kHz (35 kHz Europe) and maintains RF frequency stability of 0.005.
Connectivity includes balanced 4-wire input and output with level adjustment, auxiliary balanced audio input and output, microphone input, local headset output, and TNC antenna connectors. The base station provides compatibility with Audiocom, RTS Two-Wire, Clear-Com, RTS Digital Matrix and other four-wire systems, plus an IEC mains connector for AC power. Stage announce and relay contact closure are provided for integration with external PA or stage systems.
Typical applications include broadcast production intercom, theatre stage management, live-event technical communications, and portable production workflows where a small number of wireless users require full-duplex communications. The BTR-800 supports mixed party/private communications across two channels, allowing production teams to split talk groups without additional infrastructure. Its range is suitable for line-of-sight distances around 1,000 feet and can be extended with optional antenna systems.
Installation is straightforward with table-top or 19 inch rackmount capability and a convenient IEC power connection. The beltpack units are protected in die cast magnesium cases for shock and weather resistance, and the base station provides a clear user interface via a backlit LCD. ClearScan and frequency-agile tuning simplify setup and channel management in congested RF environments.
Overall the BTR-800 base station balances audio clarity, RF stability and system compatibility to provide dependable wireless intercom for small production teams. It combines two audio channels, full-duplex operation and integration options that make it practical for broadcast and event production environments. The design emphasizes ease of use and system interoperability while delivering professional-grade intercom features.
