Most large-scale broadcasts demand more than a single production truck. B-Units are companion support trailers designed to expand the capacity of primary A-Units by providing dedicated space for audio, engineering, replay, graphics, communications, and crew operations.
Whether supporting REMI workflows, flypack deployments, or traditional mobile production compounds, these units extend infrastructure without duplicating full control room systems. They provide workspace, power, cable management, and technical staging—allowing primary production trucks to stay focused on switching and show execution.

Expand Your Production Capacity
B-Units are essential for scaling live broadcasts. By offloading audio, engineering, communications, and operational roles into dedicated support trailers, production compounds gain space, efficiency, and workflow separation.
Whether paired with full production trucks, REMI-only units, or flypack systems, these B-Units provide the infrastructure backbone that keeps large-scale broadcasts organized and efficient.
