Mobile Unit Snapshot: MU-17 53′ 3G HDR Single-Expando Production Truck

MU-17 is a 53-foot 3G HDR single-expando mobile production truck in the Live Media Group fleet, built around a five-M/E Grass Valley Kayenne switcher with 128 inputs, an Imagine Platinum IP3 router at 476×448 under Lawo VSM control, a 64-fader Calrec Artemis Ray audio console, and eight Sony HDC-3500 HDR cameras with the truck wired for 20 CCUs. Previously known as Columbus during its Gravity Media service, it joined Live Media Group in August 2026 as the largest of the three premium trucks in that acquisition — the one built for shows that need everything at once: wireless cameras, deep replay, a big comms plant, and a 70′ × 25′ working footprint to put a full crew inside.

When the show is a marquee — multiple RF cameras roaming, 56 channels of EVS wired, fifty wireless beltpacks in the compound — this is the truck the schedule is built around. Here is what is inside.

Previously known as Columbus

MU-17 joined Live Media Group in August 2026 as part of the company’s acquisition of Gravity Media’s U.S. mobile-production assets — eight units, led by the premium trucks then named Columbus, Whiskey, and Aspen, together with Gravity’s U.S. engineering team and long-term contracts with major U.S. broadcast partners.

Those three trucks now carry Live Media Group designations — MU-17, MU-26, and MU-5. “These additional assets immediately provide us with greater scheduling flexibility while allowing us to support more clients,” said Michael Sullivan, President of Live Media, in the acquisition announcement. MU-17 is the reason that sentence is not just fleet math: a 53-foot premium unit adds top-end capacity in the class clients compete for.

Switching: five M/Es, 128 inputs

MU-17 carries a Grass Valley Kayenne UHD/3G production switcher configured for 5 M/Es, 128 inputs, and 64 outputs, with FlexiKey, DoubleTake, and chroma key licensed. Five M/Es means the TD can hold program, screens, pre-show, and an alternate feed on dedicated banks — the switching architecture large-format sports and entertainment shows assume.

Replay and record: wired for 56 EVS channels, 18 recorders

MU-17 runs four EVS XTVia LSM 12-channel replay servers, is wired for 56 channels of EVS, and carries 18 VTR/SSD record positions. That combination covers the replay room and the record wall in one truck: multi-angle LSM coverage for the show, plus isolated records, melts, and deliverables rolling in parallel.

Routing: Platinum IP3 at 476×448 under VSM control

Routing is an Imagine Platinum IP3 at 476×448 controlled by a Lawo VSM system, with 46 3G framesyncs and 272×48 of multiviewer capacity. Nearly five hundred crosspoints of routing is what lets a show this size absorb late adds — an extra feed, another iso, one more monitor — without re-engineering the truck mid-week.

Cameras: HDR chains, wired for 20 CCUs, RF-ready

MU-17 fields eight Sony HDC-3500 HDR cameras with QFR licensing, is wired for 20 CCUs (16 in UHD workflows), and supports up to six RF cameras from a 50-foot mast. The RF provision is the differentiator: integrated wireless camera support with mast-mounted reception, ready for course, field, and crowd coverage that cabled positions cannot reach. Glass includes Fujinon lenses with large-format adaptors in the support package.

Audio: Calrec Artemis Ray

The audio room is a Calrec Artemis Ray digital surround console with 64 faders and 12 dual-fader layers, supported by Trigger audio playback software. Analog, AES, MADI, and Dante I/O (120×120 analog, 128×128 AES, 640×640 MADI, and 128×128 Dante per the truck’s published I/O) give A1s the plant to land venue splits, RF mics, and mix-minuses at full-show scale.

Comms: a 320×320 matrix and fifty wireless packs

Intercom is a 320×320 RTS Adam II matrix paired with a Clear-Com Eclipse HX-Delta frame supporting up to fifty 1.9 GHz wireless beltpacks. Fifty wireless packs is compound-scale comms — stage managers, spotters, utilities, and RF camera operators all on coordinated wireless without renting a supplemental system.

Power and footprint

MU-17 needs three-phase, 190–240-volt, 200-amp service and travels with 200 feet of feeder cable. The trailer is 53′ long by 8′6″ wide, expanding to a 70′ × 25′ working footprint — a full-size production floor with seating for the crew complement a five-M/E show actually carries.

Specifications at a glance

Where MU-17 fits in the fleet

MU-17 is the top end of the August 2026 additions. Its siblings cover the classes below it: MU-5 brings 56 wired EVS channels to the 45′ class, and MU-26 packs nine Sony HDC-4300s into a 43′ expando. Around them sits the group’s full fleet of mobile units — see the complete fleet page — plus fly packs, uplink, and the Nashville control rooms for REMI and hybrid workflows.

What MU-17 is built for

• Marquee sports coverage where RF cameras are part of the format — up to six wireless chains from a 50′ mast, integrated rather than bolted on.
• Large entertainment and special-event broadcasts that need five M/Es, a 64-fader audio room, and compound-scale comms.
• Record-heavy productions: 18 VTR/SSD positions rolling isos and deliverables alongside 56 wired channels of EVS.
• Multi-feed shows using the Platinum IP3’s 476×448 routing to serve broadcast, streaming, and venue outputs simultaneously.
