The RTS RadioCom BTR-800 UHF-synthesized wireless intercom systems offer the ultimate in reliable, high performance,
high fidelity full-duplex communications. The BTR-800 system includes the BTR-800 frequency-agile base station,
working with up to four (4) TR-800 or TR-825 frequency-agile beltpacks. The BTR-800 base station provides full-duplex
communications with the beltpacks.
The BTR system incorporates two (2) audio channel operation, permitting the beltpack operator to choose between two (2)
separate audio channels of communications, with the base station tracking the beltpack selection. This allows the user the
flexibility to create a party line and a private line within the same beltpack.
The BTR-800 system is perfectly suited for standalone operation and can interface with Audiocom, RTS Two-Wire Intercom,
Clear-Com as well as RTS Digital Matrix Intercom systems and other 4-wire communications systems. In addition to the
external intercom systems interfaces listed above, the system provides connections for auxiliary balanced audio input and
output, as well as WTA (Wireless Talk-Around) and SA (Stage Announce) features.
The RTS RadioCom BTR series has been designed for reliable, efficient operation. Operating in the UHF range, the units
operate reliably at line-of-sight distances of 1,000 feet. With available antenna systems, from RTS RadioCom, the effective
operating range can be extended. The high-efficiency beltpacks provide up to 12 hours of uninterrupted operation using
standard alkaline batteries.
