Bundle consists of:

  • 1x ERECA Stage Racer 4HD TX 19" transmitter
  • 1x ERECA Stage Racer 4HD RX 19" receiver


The Stage Racer product line is an ultra flexible solution to connect a stage to an OB Van. With the ERECA unique feature for on the fly direction configurable HDSDI channels and the numerous commodities signal transmitted along the videos, the stage racer is the product of choice for an affordable fast and easy event deployment.
The equipment assumes transmission of a comprehensive set of signals as follows:

  • 4 video 3G-/HD-/SD-SDI signals (direction configurable through built in web server)
  • 1 Genlock bidirectional (PAL image / Black burst / Tri-level)
  • 16 analog audio for intercom or broadcasting
  • 2 Ethernet 10/100/1000Mbs (1 Gigabit trunk with 2 VLANS)
  • 4 Data RS 232/422/485
  • 8 Contact closures
  • 4 AES 3 bidirectional (Riedel panel compatible)
  • 1 bidirectional MADI (AES10) Signal (Shared with 2 of the 4 AES connectors)

For flexible setup the mechanical is declined in a 1U rack which fits everywhere and in a very rugged compact die cast aluminum box. This latter enclosure ensures excellent shock/drop protection along with dust and water resistant capacity for all “no fly case” applications. Links can be built between racks, rugged boxes or rack and rugged box.
All the signals are transmitted on 2 singlemode fibers. As an option, an optical cable failover is built inside the modules by adding a second connector. In case of fiber break the equipment automatically select the other cable.
STORA RX can be remote powered through Hybrid cable.


Standard connectors are used for all the signals. HD and PAL video ports are on BNC connectors. The other connectors are RJ45 / D SUB. On the rugged version 4 audio are dispatched on Neutrik XLR. Optical and remote power access is done through a Neutrik OpticalCon DUO or compatible with LEMO™ 3K socket.

Signaling / Web browser

Each equipment has a LED display panel for signal presence and alarm display.
An internal web server enables remote management and setup (signal presence report / optical power measurement / Data settings / Configure direction of each HD video signal).
