The mobile studio features state-of-the-art audio and video technology, including a Broadband Global Area Network satellite uplink, a 12-channel audio mixer, and a handheld Access Portable unit capable of effectively sending mono, stereo or dual mono audio over satellite.

Lang. “I’m no stranger to being on the road, and am thrilled to now be cruising and broadcasting in-style. This new mobile studio will allow me to break news wherever it happens, and to continue to step up my commitment to take the race fans along with me for the ride."
