1 STAGE RACER 2 SUMMARY
1.1 OVERVIEW
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 content exchange
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…
1.2 CONNECTIVITY
The Stage Racer 2 is available in two standard configurations: 12 or 24 SDI channels 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 bidirectional channels
(direction configurable)
8 SD to 3G bidirectional channels
(direction configurable)
8 SD to 12G bidirectional channels
(direction configurable)
4 SD to 12G bidirectional channels
(direction configurable)
1 Distributed Genlock (Composite video / Black burst / Tri-level)
16 Bidirectional analog audio
2 Ethernet 10/100/1000Mbs
2 Data RS 232/422/485
8 Contact closures
4 AES 3 bidirectional (Intercom panel compatible)
1 Bidirectional MADI (AES10) Signal (Shared with 2 of the 4 AES connectors)
1.3 TRANSMISSION
Transmission is based on TDM multiplexing for the all signals managed by the system. Each TDM multiplex
is transmitted to another machine by “Trunk” ports. Each machine can have up to 4 trunk ports on dual
LC/PC socket.
For remote production applications, the machine will act as a bridge between the standard and the IP world
with future compliance to SMPTE ST2110 standards. Signals managed locally can be sent over IP and vice
versa.
