STAGE RACER 2
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…

Overview
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…
Connectivity
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:

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

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.
