24 or 12 SDI HD, 12G Support, Genlock, IP, Audio, AoIP, Serial Data, GPIO, routing, distribution, processing unit, star/ring/linear network topology and much more…


The STAGE RACER 2 is a complete optical fibre transmission solution for every broadcast event, ranging from simple OB interconnect to complex star, ring or linear topology spread over a whole TV compound.
It also supports long distance transmission for remote production capacity allowing exchange content between distant locations.

Stage Racer 2 is designed to accept all kinds of signal on a same device without external adapter. Internally those signals can be associated together / routed / distributed to all other machines of the network.

Stage Racer 2 also offers processing capabilities with Audio Embedding/De-embedding, Audio SRC, Frame buffering, and much more…

Stage Racer 2 network can be controlled by a built-in intuitive web interface or with automation systems like VSM, KSC Core…
