RTS BTR-800E88R5 Base Station A5F Headset Jack E88 Band UHF Synthesized 2-Channel Full-Duplex

Description

The BTR-800 base station is a UHF-synthesized wireless intercom hub designed to provide full-duplex communications between a central station and up to four wireless beltpacks. It operates across the 470 – 608 MHz and 614 – 740 MHz E88 band ranges and supports two independent audio channels for flexible party-line and private-line workflows. The unit is available as a table or rackmount form factor to fit broadcast and live production racks.

Key features include frequency agility with synthesized tuning, a backlit LCD for beltpack status monitoring, and ClearScan channel selection that finds the best operating frequencies. The system supports stage announce and wireless talk-around controls from the beltpacks and offers relay contract closure on the base when the stage announce button is pressed. Transmit power is selectable with 100 mW maximum and 10 mW normal output settings.

Performance details include FM modulation with 40 kHz deviation (35 kHz in Europe), RF frequency stability of 0.005, and a frequency response of 300 Hz to 8 kHz for clear voice reproduction. The platform supports up to four users simultaneously and the beltpack battery life is approximately 12 hours on standard alkaline cells. Radiated harmonics and spurious emissions exceed FCC specifications to ensure regulatory compliance.

Connectivity includes adjustable 4-wire input and output levels, auxiliary balanced audio input and output, local headset output rated at 40 mW into 600 ohms, and a microphone input sensitivity listed in the product data. The base station uses a supplied 1/2 wave antenna with TNC male connectors for TX and RX and an IEC power inlet for AC mains connection. The BTR-800 integrates with Audiocom, RTS two-wire, Clear-Com and RTS digital matrix systems and other four-wire intercom environments.

Typical applications include broadcast production control rooms, live event communications, theater stage management, and film production where reliable wireless beltpacks and channel separation are required. The system supports both binaural stereo and mono beltpack operation on compatible beltpacks to accommodate headsets and earpiece configurations. Its two-channel operation lets crews maintain a party line and a private channel simultaneously to segregate production and technical traffic.

Installation is straightforward – the base is rackmountable or deployable on a table and includes an IEC power connector for standard AC feeds. The die-cast magnesium beltpacks provide weather and shock resistance for field use and the ClearScan function simplifies frequency selection in congested RF environments. Overall the BTR-800 delivers a dependable, easy-to-integrate wireless intercom solution for professional AV and broadcast teams.
