The Telex TR-300 is a portable, license-free wireless beltpack transceiver designed for professional intercom communication in live event production, broadcast, and theater environments. Operating in the VHF or UHF band, it provides clear, two-way, full-duplex audio between crew members such as stage managers, camera operators, and technicians who require untethered mobility. This beltpack unit functions as both a transmitter and receiver, allowing wearers to communicate seamlessly with each other and with a wired base station or other wireless units, forming a flexible extension of a larger intercom system.

The device is built for durability and ease of use in demanding field conditions, featuring an intuitive control layout with volume adjustment, channel selection, and a call signaling button. It is typically powered by a rechargeable battery pack, offering several hours of continuous operation on a single charge. The TR-300 often includes a high-quality, noise-canceling microphone and a connection for a standard aviation-style headset, ensuring intelligible communication even in high-noise environments like concert stages or sporting events.

As a key component in a wireless intercom system, the Telex TR-300 enhances crew coordination and operational safety by providing reliable, hands-free communication without the limitations of cables. Its portability and robust construction make it a valuable tool for film crews, live event production teams, and any application where clear, instant communication is essential for a smooth and successful production.
