The Clear-Com WTR-670-BP is a professional wireless intercom beltpack designed for the 600 Series UHF wireless systems, providing full-duplex communication for users who require reliable mobility. Operating in the UHF frequency range, it offers robust performance with the ability to select clear channels to avoid interference, making it suitable for complex RF environments like large live events, broadcast facilities, and touring productions. The beltpack provides true, simultaneous two-way communication (full-duplex), allowing for natural conversation without the push-to-talk delay typical of half-duplex systems, which is critical for fast-paced coordination among directors, stage managers, and technical crew. It is typically used in conjunction with a compatible base station that manages the wireless network and links to a wired intercom system.

The beltpack is built for durability and ease of use in demanding conditions. It features an intuitive interface with controls for volume, channel selection, and a call/alert button, along with a clear display showing frequency, battery status, and signal strength. It is powered by a rechargeable battery pack that offers extended operational time, ensuring it can last through long production days. The unit includes a standard 4-pin XLR connector for connecting a wide variety of Clear-Com wired headsets or boom microphones, providing flexibility for user preference and application. Its metal chassis and robust construction are designed to withstand the physical rigors of professional use.

Integration into an existing intercom infrastructure is a key strength. The WTR-670-BP wirelessly connects to its base station, which can then be interfaced with analog party-line or digital matrix intercom systems. This allows wireless users to communicate seamlessly with all other wired participants in the production. The system supports multiple independent channels, enabling private talk groups. With its combination of UHF reliability, full-duplex audio quality, and professional build, the Clear-Com WTR-670-BP beltpack delivers a powerful wireless communication tool that enhances operational flexibility and crew coordination in environments where wired solutions are impractical.
