MU-B5 | 53’ Single Expando Support Unit

Modular Mobile Workspace for Engineering, Audio, and Production Teams

The MU-B5 is a 53-foot single expando support trailer, built to serve as a flexible and scalable field operations unit for live broadcast, remote production, and technical integration. Combining a working footprint of nearly 20 feet wide when expanded and 10 configurable operator positions, MU-B5 delivers production-critical infrastructure in a compact but highly capable trailer format. It is purpose-built for crews who require climate-controlled work zones, cable management, and support logistics near the main production compound.

Whether deployed as a standalone engineering base, a comms and audio office, or an overflow crew trailer, MU-B5’s strength lies in its adaptability. With clear segmentation between storage, technical work zones, and operational seating, it supports a wide variety of live event use cases—from REMI staging to major sports productions and festival support.

Vehicle Specifications

  • Trailer Length: 53 ft
  • Working Dimensions: 61’ L x 19.5’ W (expanded)
  • Structure Type: Single Expando
  • Workstations: 10 Operator Positions
  • Gross Vehicle Weight: Not specified (support trailer class)
  • Power Requirements:
    • Single Phase, 208 Volts
    • 150 Amps
    • Camlock connectors for generator or shore power tie-in

Floorplan Layout

The floorplan on page 1 of the MU-B5 specification clearly divides the unit into four distinct zones:

  • Chapman Storage: Located at the rear, this section includes shelving and space for flypacks, fiber drums, camera cases, expendables, and other support gear. It is accessible via rear load-out ramp and side entry.
  • Engineering / Cushman Bay: This is a closed, climate-controlled work area for technical staff. It includes counter workspace and is ideal for system integrators, EICs, and engineers managing routing, audio tie lines, and system health.
  • Audio / Office Room: A flexible office zone for audio supervisors, comms operators, or production management. This space is commonly used for phone comms, intercom coordination, or show calling.
  • Flex Work Zones 1 & 2: The largest area in the expando portion, Flex 1 and Flex 2 include a shared deskline with seating for up to 6 operators. These positions are modular and can be equipped for any combination of comms, fiber patching, network control, IP management, or show ops.

This layout ensures multiple departments can operate simultaneously without overcrowding or signal interference.

Cable Infrastructure

MU-B5 includes customizable cable inventory based on production needs. Live Media Group equips the trailer per event with appropriate runs of:

  • Triax
  • DT12 Audio
  • SMPTE Hybrid Fiber
  • TAC-12 Tactical Fiber
  • XLR Audio
  • Coaxial Looms (5-wire, 10-wire)

This flexibility allows MU-B5 to serve as a mobile patch room, fiber terminus, or flypack deployment base—especially in distributed REMI environments.

Power & Climate

  • Power: 208V, 150A, Single Phase
  • Cooling: Full HVAC climate control
  • Connectivity: Camlock power input for integration into remote compounds or utility drops

The environmental design ensures stable operation for both personnel and rack-mounted systems, even in high-heat or high-traffic scenarios.

Applications

MU-B5 is ideal for:

  • Support trailer for REMI and hybrid production compounds
  • Audio and communications base station
  • Engineering room for cable patching and signal integrity monitoring
  • Overflow workstations for large-scale shows
  • Flypack staging and prep area

When deployed alongside main trucks such as MU-10, MU-14, or MU-28, MU-B5 provides critical infrastructure to offload signal management and technical prep, giving crews room to focus on mission-critical operations in the core units.

Why MU-B5 Stands Out

MU-B5 brings together space, modularity, and customization in a way few support trailers can. Its single-expando footprint enables more interior room while still fitting into tighter compounds than double-expando units. With flexible zones, custom cable options, and robust power specs, it adapts seamlessly to any technical or operational role required. MU-B5 is an essential addition to high-demand productions looking to expand team infrastructure without sacrificing mobility or speed.
