The RTS BP-300 is a professional two-channel, portable intercom belt pack designed to provide clear and reliable communication in demanding broadcast, live event, and theatrical production environments. As a user station within the RTS Twisted Pair (TW) intercom ecosystem, it connects personnel such as camera operators, stage managers, and technicians to a central matrix or party-line system via standard low-voltage twisted pair cabling. The BP-300 offers access to two independent communication channels, allowing users to listen to a primary channel like the director's feed while having the ability to communicate on a secondary channel dedicated to a specific department, such as lighting or audio, enhancing coordination and workflow efficiency.

Constructed with durability as a priority, the belt pack features a rugged metal chassis that can withstand the physical rigors of daily use on set or backstage. Its user interface is intuitively designed for operation in low-light conditions, with large, tactile buttons for channel selection, a prominent call button, and a rotary knob for headset volume control. A second knob typically adjusts the sidetone level, allowing users to hear their own voice in the headset at a comfortable level, which is crucial for preventing shouting and maintaining natural conversation in noisy environments. The unit is powered directly from the intercom line, eliminating the need for batteries and ensuring uninterrupted operation throughout an event or production day.

The BP-300 is designed for seamless integration and mobility. It includes a sturdy metal belt clip and uses industry-standard connectors—commonly XLR—for connecting a headset and for daisy-chaining to the next user in the line. It provides high-quality, balanced audio with excellent noise rejection, ensuring intelligible communication even in acoustically challenging locations like concert side stages or sports fields. As a core component of the RTS intercom system, the BP-300 belt pack delivers the dependable, real-time communication that is vital for the coordinated execution of complex productions, empowering mobile crew members with reliable connectivity and control over their monitoring experience.
