Mobile Unit Snapshot: B3 A 53’ Straight Support Unit for Live Broadcast Engineering & Field Production

As live broadcasts and remote productions scale in size and complexity, technical teams need more than just switching and camera trucks—they need structured, efficient support environments where operations can run smoothly. Enter MU-B3, a 53-foot straight support trailer from Live Media Group’s mobile infrastructure fleet.

Built to serve as an engineering, audio, or production annex, MU-B3 provides a climate-controlled workspace with 10 operator positions, segmented zones, and per-show cabling options. Whether used for REMI staging, audio system prep, engineering patching, or flypack support, this non-expanding trailer is the backbone for live event teams who require both mobility and reliability.

Purpose-Built for Technical Production Teams

MU-B3 is not a switching or replay truck. Instead, it’s where the support happens. Technical personnel, producers, and integrators can collaborate here without crowding the primary production vehicle. With its straightforward, modular layout and robust infrastructure capabilities, MU-B3 excels in environments where space, order, and cable control are vital.

It’s particularly useful for:

• Engineering teams managing signal flow and fiber routes
• Audio and comms leads prepping IFB and intercom systems
• Production managers overseeing show documentation and tech plans
• Flypack crews organizing camera builds, cases, and field gear

Interior Layout Designed for Workflow Efficiency

MU-B3’s internal layout mirrors that of its sister unit, MU-B1, with clearly segmented functional areas to avoid cross-talk, cable confusion, and workspace congestion.

• Chapman Storage Room (Rear)
  Accessible via ramp, this storage space includes shelving for flypack racks, cable drums, camera kits, and expendables. It serves as a secure gear landing zone.
• Cushman and Audio/Office Room
  An enclosed private space for audio prep, comms control, or production planning. Ideal for leads who require phone access, quiet comms coordination, or onsite management.
• Main Production Bay
  The center of MU-B3 features seven operator positions along a shared deskline. Perfect for technical directors, fiber patch engineers, or network support personnel to work side-by-side.
• Engineering Bay (Front)
  Positioned near the power distribution and environmental systems, this space is optimized for patching, signal monitoring, and infrastructure coordination.

This physical separation of disciplines allows your team to focus on their task without interference from other departments—all while working in proximity for fast communication and handoffs.

Mobile Cabling & Signal Infrastructure

MU-B3’s cabling is configured per project, ensuring that the trailer adapts to your event rather than the other way around. Standard cable packages available for deployment include:

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

This makes MU-B3 incredibly versatile—serving as a mobile patch room, fiber terminus, or temporary production extension depending on the needs of the event.

Power and Environmental Design

• Power: Single Phase, 208V @ 150A
• Connection: Camlock input for integration with on-site generator or shore power
• Cooling: Full HVAC climate control throughout the trailer

These specs support full-day field operations and ensure a stable environment for personnel and rack-mounted gear, even during high-temperature or high-traffic shows.

Ideal Applications for MU-B3

MU-B3 is a go-to solution when your crew needs structure, scalability, and flexibility on location. Use it as:

• A mobile engineering annex during REMI productions
• A production office for field supervisors and coordinators
• A comms and audio prep room for IFB, PL, and routing
• A patching and fiber hub for multi-camera or flypack shows
• Overflow workspace when main control trucks are at capacity

Whether paired with trucks like MU-10, MU-14, or MU-28—or standing on its own—MU-B3 provides the infrastructure that keeps large events running smoothly.

Why MU-B3 Stands Out

MU-B3 is the backbone of technical coordination. While it doesn’t have switchers or EVS replay servers, it houses the people who control them, and it gives them the space to work clearly, effectively, and comfortably. Its non-expando format makes it easier to deploy in tighter truck compounds, while its modular zones and 10 operator positions deliver the capacity needed for modern production demands.

When multiple crews are working onsite or a centralized flypack strategy is in play, MU-B3 ensures that your engineering, audio, and production workflows have room to breathe.

FAQ for MU-B3

What is MU-B3 used for?
MU-B3 is a mobile support trailer used for engineering, audio, and production support during live events and remote broadcasts. It does not include switching or replay systems, but it provides workspace and infrastructure for technical teams.

How many people can work inside MU-B3?
MU-B3 supports 10 working positions across multiple zones, including a main production bay and private office areas.

Does MU-B3 include any built-in cabling?
Cable packages are custom-configured per show. Available options include Triax, DT12, SMPTE, TAC-12, XLR, and coaxial looms.

Can MU-B3 be used with REMI or flypack productions?
Yes. MU-B3 is ideal for REMI workflows and flypack integration. It often serves as a field engineering trailer or fiber patch hub.

Is MU-B3 climate-controlled?
Yes. MU-B3 features full HVAC to maintain a stable operating environment for equipment and staff.

Does MU-B3 have power requirements?
MU-B3 requires 208V single-phase power at 150 amps, with Camlock input for generator or shore power tie-in.

Can MU-B3 serve as a mobile production office?
Absolutely. The interior includes enclosed spaces and operator seating ideal for production management, comms coordination, or field admin work.

How is MU-B3 different from MU-B1?
MU-B3 shares a similar layout with MU-B1 but offers expanded scheduling flexibility and deployment across additional event zones.

MU-B3 is available for rental or integration planning. Cable sets, operator positions, and floorplans can be customized.
