The Essential Link for Hybrid Productions

The Datavideo TB-20 is a specialized tally interface box designed for broadcasters using a mix of Datavideo and Panasonic hardware. Specifically engineered to connect the Datavideo ITC-100 eight-user intercom system to the popular Panasonic AG-HMX100 digital switcher, the TB-20 ensures that your tally information is never lost in translation. It acts as the "brain" that tells your camera crew exactly when they are on-air or standing by.

Advanced Tally Cues and Precision

Precision timing is the difference between a good broadcast and a great one. The TB-20 extends the ITC-100’s bi-color tally function, providing clear visual indicators to your crew. By interpreting the signal from the Panasonic switcher, it triggers the Red light for "Live" status and the Amber light for "Cue" information on the ITC-100SL beltpacks. This real-time feedback allows camera operators to frame their shots and move with confidence.

Professional D-Sub Connectivity

Interfacing different brands requires a secure physical connection. The TB-20 features a robust 25-pin D-Sub connector that provides a stable path for multi-channel tally data. This professional-grade port is designed to prevent signal drops, ensuring that your tally lights remain active and accurate throughout the longest live events, from high-stakes corporate presentations to multi-camera religious services.

Versatility for Custom Workflows

While the TB-20 is optimized for the AG-HMX100, its design offers inherent flexibility for technical directors and engineers. The internal wiring and 25-pin architecture can be reworked or adapted to interface with other Panasonic switcher models that utilize similar tally outputs. This makes the TB-20 a versatile "Swiss Army Knife" for any production house looking to maintain their existing Panasonic switching infrastructure while upgrading to Datavideo’s industry-standard intercom systems.
