MU-4 45′ 3G Single Expando Overview
MU-4 is a 3G single-expando mobile production unit built for high-performance live broadcasts. Designed for sports, concerts, corporate events, and award shows, it pairs a five-M/E Grass Valley K-Frame switcher with a 56-fader Calrec audio console, Evertz video and audio routing, Grass Valley SMPTE HDR cameras wired for 12 CCUs, 34 channels of EVS replay, and a 160×160 RTS Adam intercom, all in a compact yet expandable footprint.
Dimensions and Configuration
MU-4 offers a well-optimized layout that balances interior working space with mobility.
- Base length: 43 ft
- Base width: 8.5 ft
- Expanded section: 36 ft × 13.5 ft
- Total length (with tractor): 78 ft
- Gross vehicle weight: 80,000 lbs (max)
This configuration provides ample operator space while remaining maneuverable for diverse venues and remote production environments.
Video Production Technology
MU-4’s video infrastructure is centered on the Grass Valley K-Frame 3G switcher.
Switcher capabilities:
- 5 M/E, 64 inputs / 48 outputs
- Image Store with movies
Record & Playback
MU-4 is wired for 34 channels of EVS XT-3, giving fast turnaround for replays, highlights, and multi-angle playback during high-intensity live events.
Camera System
MU-4 is a SMPTE truck built around Grass Valley LDX 86 SMPTE HDR WorldCams.
- Wired for 12 CCUs
- Camera and lens configurations available to fit each show
Audio Capabilities
MU-4’s audio is mixed on a Calrec Artemis Light Bluefin 2 digital console.
Console features:
- 56 faders
- 64×64 analog
- 64×64 AES
- 256×256 mono MADI
- 64×64 Dante
- 64×64 Waves Broadcast Suite
This gives audio teams the processing and I/O to handle complex, multi-source mixes.
Routing and Multiview Systems
Signal management is powered by the Evertz EQX 3G video router (280×458).
Video router:
- 96×64 embedding / de-embedding

These systems provide comprehensive routing and monitoring across cameras, replay, graphics, and transmission paths.
Communication Infrastructure
Clear, reliable crew communication runs through a 160×160 RTS Adam matrix intercom.
Intercom features:
- 64 OMNEO channels
- 16 RVON channels
- 32 MADI channels
- 8 powered PL channels
- 6 powered IFB channels
Stations and accessories:

Why MU-4 Stands Out
MU-4 combines five-M/E switching, SMPTE HDR cameras, a 56-fader Calrec console, deep Evertz video and audio routing, 34 channels of EVS replay, and full RTS intercom in a proven, reliable platform. It’s a trusted solution for producers who need quality, stability, and adaptability in high-pressure live environments.
Applications
MU-4 is ideally suited for:
- Live sports broadcasts
- Concerts and music specials
- Award shows and red carpet events
- Corporate events and live streaming
- Worship events and live television productions
