Gearhouse Broadcast relies on Lawo to equip its Columbus OB truck

Operating fully in 4K and with up to 16 cameras, Columbus is Gearhouse Broadcast USA’s newest OB Mobile Unit. Designed to serve both large sports and entertainment productions, Gearhouse turned to equipment from Lawo for many of the critical components of the impressive build.


While Gearhouse Broadcast’s UK-based systems integration team handled the build, the truck is available for 4K and HD productions in the US. With up to 16 4K/HD cameras, six additional inputs for RF cameras, a full 4K monitor wall, it relies on Lawo’s VSM System plus high-end audio tools and IP-based video processing equipment also from Lawo.


Lawo’s mc²56 audio console

Columbus is equipped with a 64-fader mc²56 audio console in a 48-bay frame with an integrated routing matrix of 8192 x 8192 crosspoints. The console offers 540 full processing channels, 64 AES I/O on the main core with 32 MADI and 4 RAVENNA/AES67 interfaces. The console has a fully redundant architecture.


Through the deployment of the mc²56, Lawo addressed Gearhouse’s requirements for many faders in a small footprint, as well as providing custom configuration to address a wide range of workflow requirements, as Lawo confirms.




The meter bridge shows all fader Ievels on the console’s HD touchscreen displays, with multi-row metering allowing viewing of all fader levels as well as signals from other layers or banks. The overbridge also accommodates additional modules, such as a user panel or RTW goniometer.


VSM control and monitoring system

At the heart of the OB truck is a VSM control and monitoring system on redundant servers that has access to and controls all relevant hardware in the OB. With VSM, users have access to the routing parameters of the Imagine Platinum routers and multiviewers, the Grass Valley Kayenne vision mixer, and the RTS intercom, as well as the Lawo mc256 audio console and DALLIS frame.


Using the VSM panels, operators can prepare and save complete workflows in advance of a production, and can recall complete global snapshots of the whole truck with a button-push shortly before going live. In addition, the VSM system acts as a full tally and labeling system with no need for a dedicated single tally solution.


A further part of the installation involves three Lawo V_pro8 8-channel video processors, which allow interfacing of different video formats, as well as audio management, frame synchronization and embedding and de-embedding of audio to the 4K signals.
