24 or 12 SDI, 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 fiber 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 content exchange between distant locations while using dark fiber or SMPTE IP protocols.

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 shuffling, Audio SRC, Frame buffering, Delays… Numerous other processing functions will be added later on.

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


The Stage Racer 2 is available in two standard configurations: 24 or 12 SDI channels, direction configurable, plus a common set of signals. Each equipment assumes transmission of a comprehensive set of signals as follows:

Stage Racer 2 – 24 SDI version

Stage Racer 2 – 12 SDI version

16 SD to 3G direction switchable channels

8 SD to 3G direction switchable channels

8 SD to 12G direction switchable channels

4 SD to 12G direction switchable channels

1 Distributed Genlock (Composite video / Black burst / Tri-level)

16 Analog Audio I/O (optional 8ch mic gain/48V module)

2 Ethernet 10/100/1000Mbs (optional 64ch Dante/AES-67 AoIP module)

2 Data RS 232/422/485 (optional 6 additional 500Kbps RS422 serial channels)

8 Contact closures

4 AES3 bidirectional (Intercom panel compatible)

1 MADI I/O (AES10) signal (Shared with 2 of the 4 AES connectors)

Processing features

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.

  • Framebuffer & Delays:  16 framebuffers / framesynchronizers available per unit on all 3G ports.
  • Embedding/De-embedding: Audio can be inserted or extracted from any SDI port of the system or shuffled between one port to another.
  • Audio Processing: SRC on almost audio I/O allowing to route any audio source to any kind of audio output (Analog, MADI, Dante/AES-67, SDI Audio, AES* soon)
  • 3rd party control: Ember+ support for remote control via third party equipment like Cerebrum, KSC Core, VSM…
  • More to come: From its launch, Stage Racer 2 improves with regular firmware upgrades providing new processing features and improved ergonomics. Stay tuned.
