Page 4: Stage Racer 2 Summary
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. -
Page 5: Connectivity
5 / 56 1.2 CONNECTIVITY The Stage Racer 2 is available in two standard configurations: 24 or 12 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 –... -

Cameras. Battery energy will be drawn only if both mains sources are down, when mains will reappear battery current draw stops. Note: The Stage racer 2 cannot charge the external battery from its own power sources. ERECA, 75 rue d'Orgemont, 95210 Saint Gratien, France T: +33 1 39 89 76 23 W: ereca.fr... -
Page 7: Detailed Description
The internal fans speed is automatically adjusted depending on the internal motherboard temperature. At room temperature, the fans run at minimal speed allowing the Stage Racer 2 to be used in a quiet environment. For field application a 4 to 5 RU fly case integration offers sufficient room for properly expending all the connections on panel BNC and XLR sockets. -

Page 12: Aes / Madi
Each AES port is internally equipped with a 2-4 wire converter connected to transmit a fully bidirectional path to any distant AES port of the Stage Racer 2 network. It appears in the AES audio grid of the network. This allow to interconnect talkback panels working in a bidirectional manner on one 75 Ohms coax. The ports still can be used without configuration to transport unidirectional signal, no setup needed for channel direction. - Page 13 Similarly, a Madi output can be created by picking signals of various sources (Analog/Dante/Madi/ AES/SDI De- Embedded) present in the stage racer 2 network. This job is done from the Audio grid. In this case MADI transits thru and SRC and is synchronous of the genlocked audio audio clock derived from the Genlock supplied by the user.

Page 14: Dante / Aes-67
The Dante / AES-67 board is an optional hardware module provided by Ereca, which provides 64 channels in and out. Each individual Dante audio channel can be selected and affected to the stage racer 2 internal audio bus and routed to any stage racer 2 audio output interface (Analog/Dante/Madi/SDI Embedded). -
Page 15: Sdi Embedding / De-Embedding

Page 25: Optional Connectors
If impedance matching is needed a small form factor resistor (Eg: SFR16) could be added directly on the D SUB pins, together with the signal wire. Note 1: For RS 485 Telex/RTS talkback panels please ask ERECA for wiring tip. Note 2: As the differential inputs are unloaded internally a small crosstalk should happen on the adjacent channel only if it is unused and left floating. -

Page 35: Audio Shuffling , Embedding-De-Embedding
Transmission principles The stage racer 2 allow an unlimited audio transport capability. For the audio channels where the user want to act on (shuffling) have to pass thru the processed audio bus. For the audio signals that only have to transit thru the SR2 network, it can be transmitted by the packet audio bus without looking into (Madi /Aes). - Page 36 Note that MADI signal can be distributed thru the SR2 network like and SDI signal. It’s not possible for AES as they are made bidirectional by essence in the SR2. ERECA, 75 rue d'Orgemont, 95210 Saint Gratien, France T: +33 1 39 89 76 23...

Page 44: Trunks, Bandwidth, Redundancy, Priorities
The number of signals and their format will influence the amount of bandwidth required. The Stage Racer 2 system will dynamically allocate these signals in the available fiber trunks whenever there is sufficient bandwidth left. Anyway if a signal reach a node and is not needed afterwards the bandwidth is then allowed for other signals. -
