Mobile Unit Snapshot: MU-B9 A 53′ Advanced Support Unit for REMI and Hybrid Workflows

MU-B9 | 53-Foot Single Expando Broadcast Support Trailer

Modular Mobile Work Trailer for Engineering, Production, and REMI Workflows

The MU-B9 is a 53-foot single-expando support trailer purpose-built to provide technical workspaces, engineering infrastructure, and overflow capacity for complex live production environments. Designed for maximum functionality in remote and hybrid broadcast workflows, MU-B9 delivers 10 fully equipped operator workstations, dual climate zones, and a segmented interior layout to support multiple departments simultaneously. It is ideal for REMI deployments, flypack integration, broadcast truck compounds, or any large-scale event requiring flexible work and coordination space in the field.

With a footprint of 60 feet by 23 feet when fully expanded, MU-B9 offers dedicated spaces for engineering staff, show callers, production leads, A1 audio techs, data engineers, and comms personnel. Its zone-based layout and robust cable infrastructure make it a versatile companion to mobile control rooms and production vehicles such as MU-14, MU-16, or MU-28.

Interior Floorplan and Work Zones

MU-B9 is designed around five independent work zones that keep technical, production, and audio workflows separated but connected:

• Production Zone: Features seven operator seats in a shared deskline. This area is used for producers, show callers, technical directors, EICs, and coordination staff. It offers a collaborative layout for managing onsite operations.
• Engineering Room (ENG): Includes two workstations for routing, signal integrity, fiber patching, or system monitoring. It is designed to isolate technical workflows and reduce noise interference.
• Audio Bay: Centrally located and acoustically treated, the audio bay supports A1 engineers, intercom leads, and monitoring roles. It provides a quiet environment for precision audio operations.
• Flex Zones 2 and 3: Floating workspaces ideal for data techs, IT staff, network engineers, and overflow crew. These spaces support network control, IP management, or comms operations.

Multiple entry points provide direct access to key areas of the trailer, reducing traffic through signal-sensitive zones and improving efficiency during high-demand show operations.

Cable Infrastructure

MU-B9 includes customizable cable infrastructure based on project needs. Live Media Group configures each deployment with the appropriate inventory, including:

• SMPTE hybrid fiber
• DT12 audio multicore
• TAC-12 tactical fiber
• Triax camera cable
• Analog XLR audio
• 5-wire and 10-wire coaxial looms

The trailer is commonly deployed as a cable patch hub or fiber termination point, supporting both truck-based and flypack-based systems in live production environments.

Use Cases

MU-B9 is engineered to serve a wide range of remote production needs, including:

• Technical overflow during multi-unit productions
• REMI support for switching and replay housed in centralized facilities
• Onsite engineering and routing control
• Production management and show calling in large venues
• Signal patching, network monitoring, and fiber management
• Audio comms and intercom prep
• Temporary control or recovery environments for mission-critical live broadcasts

Why MU-B9 Stands Out

MU-B9 is more than a workspace—it’s a production-critical asset that expands a crew’s operational capacity without requiring a full mobile control room. Its single-expando design offers expanded square footage with easier deployment logistics than dual-expandos. The trailer’s climate control, dedicated audio and engineering bays, and flexible workstation setup make it indispensable in large, complex shows where additional headcount and infrastructure are required.

MU-B9 is an ideal companion to REMI broadcast trucks, central control rooms, and multi-city live productions, enabling teams to scale quickly while maintaining signal integrity, crew efficiency, and workflow separation.
