Mobile Unit Snapshot: B5 A Scalable, Single Expando Support Trailer Built for Live Broadcast Engineering, Audio, and REMI Workflows

For sophisticated live production environments, engineering and operations teams need more than just switchers and servers—they need space to work, organize, and manage signals at scale. The MU-B5 support unit was designed to meet that need. A 53-foot single-expando trailer, MU-B5 functions as a flexible workspace for broadcast engineers, comms operators, and audio supervisors who require operational clarity and physical separation from the main control room.

Built by Live Media Group, MU-B5 delivers field-ready infrastructure that supports remote productions, REMI workflows, festival coordination, and national-scale sports events. With 10 modular workstations, a climate-controlled environment, and per-show cabling configurations, MU-B5 ensures your crew has the room—and resources—they need to execute at the highest level.

Designed for Flexibility, Engineered for Productivity

MU-B5 features a full-length single expando that increases the trailer’s working width to nearly 20 feet, enabling a segmented but collaborative environment. The interior layout is divided into four core zones, each with a distinct purpose and infrastructure:

  • Chapman Storage Bay: Located at the rear, this load-out area features shelving and open space for flypacks, fiber drums, expendables, and camera gear. It’s accessible via both rear ramp and side door, allowing fast ingress and egress for field operations.
  • Engineering / Cushman Bay: A climate-controlled technical room optimized for system integration, patch management, and routing. It offers counter workspace and is ideal for broadcast engineers, tech managers, or EICs.
  • Audio / Office Room: A smaller enclosed room suited for comms control, audio coordination, or production management. It’s frequently used by A1s or production supervisors for show calling, comms routing, or IP phone integration.
  • Flex Work Zones 1 & 2: The heart of the expando section, these zones include seating for up to six operators and can be customized for fiber patching, IP routing, communications control, or event coordination.

This configuration makes MU-B5 ideal for shows that require technical modularity, clean signal paths, and flexible team coordination, whether operating REMI or centralized production workflows.

Custom Cabling for Custom Shows

No two shows are the same—and MU-B5 is built with that in mind. For each deployment, Live Media Group provisions the trailer with a custom cabling package that can include:

  • Triax Camera Cable for legacy compatibility
  • SMPTE Fiber for UHD and IP workflows
  • DT12 Audio Multicore for booth/stage feeds
  • TAC-12 Tactical Fiber for long-range connectivity
  • XLR and 4-Pair Audio for analog audio patches
  • 5-Wire and 10-Wire Coaxial Looms for SDI and RF

The result is a fully customizable cable lab on wheels, ready to handle complex patching needs without disrupting the control room or main production vehicles.

Reliable Power & Climate Control

MU-B5 is powered by single-phase 208V service at 150 amps, making it compatible with venue drops or generator-based compounds. The onboard Camlock power input ensures rapid setup and clean integration with larger shows.

Inside, full HVAC ensures thermal stability for rack-mounted gear, patch bays, and personnel—crucial for long shoot days or temperature-sensitive operations.

Ideal Applications for MU-B5

MU-B5 shines in any high-capacity or distributed broadcast environment where field engineering, REMI integration, or offboard audio/comms require a dedicated space. Common use cases include:

  • REMI & hybrid production staging
  • Mobile comms and IFB coordination
  • Audio infrastructure for multi-stage festivals
  • Flypack launchpad for camera and fiber prep
  • Engineering zone during venue transitions
  • Overflow crew workstations when main trucks are at capacity

When deployed alongside units like MU-10, MU-14, or MU-28, MU-B5 acts as an infrastructure multiplier, giving tech crews the ability to offload cable management, routing, and equipment prep—without impacting core broadcast operations.

Why MU-B5 Stands Out

The MU-B5 fills a critical niche in today’s event production world. While many trucks focus on switching, replay, or transmission, MU-B5 focuses on the support systems that make them all work together. Its single-expando design strikes a balance between compact travel and expansive internal space. Its modular zones allow for precise team deployment, and its custom cable configuration adapts to your show’s needs.

For production teams juggling comms, fiber, patching, and IP management, MU-B5 becomes the quiet hero behind the scenes—making sure your signal arrives clean, clear, and on time.
