Introduction

General Description

The Telex RadioCom™ BTR-800 UHF Synthesized Wireless inter com systems offer the ultimate in reliab le, high-performance, high-fidelity full-duplex communications.

The BTR-800 system includes the BTR-800 frequency agile base station, working with up to four TR-800 or TR-825 fre- quency agile beltpacks. The BTR-800 base station provides full-duplex communications with the beltpacks.

The BTR system incorporates two audio channel operation, permitting the beltpack operator to choose between two sepa- rate audio channels of communications, with the base station tracking the beltpack selection. This allows the user the flexi- bility to create a party-line and a private line within the same beltpack.

The BTR-800 system is perfectly suited for stand-alone opera- tion and also can interface with Audiocom® (Telex), RTS® TW, Clear-Com®, as well as RTS Matrix systems and other 4-wire communications systems. In addition to the external in- tercom systems interfaces listed above, the system provides connections for auxiliary balanced audio input and output, as well as wireless talk-around (WTA) and stage announce (SA) features.

The RadioCom™ BTR series has been designed for reliable, efficient operation. Operating in the 470 to 740 MHz range, the units operate reliably at line-of-sight distances of 1,000 feet. With available antenna systems, from Telex, the effective operating range can be extended. The high-efficiency beltpacks provide up to 12 hours of uninterrupted operation using standard alkaline batteries.
