2.3.5 DANTE
The optional Dante board capacity provided by Ereca is 64 channels in and out.
Each individual Dante board channel can be selected and affected to the stage racer internal audio bus and
routed to any stage racer 2 audio output interface (Analog/Dante/Madi/SDI Embedded).
Similarly Dante output channels can be populated by picking signals of various sources (Analog/Dante/
Madi/SDI De-Embedded) present in the stage racer 2 network. All of those signals appear in the Audio
audio grid of the stage racer 2 network.
The Dante board embedded in the Stage racer 2 will appear as a slave in the user Dante controller.
Two SRC are used to synchronize DANTE inputs to the Stage racer 2 internal audio frequency and to
synchronize Stage racer 2 internal audio to DANTE outputs.
Note1: The Dante board is available on port IP-1. It can be ‘’disconnected’’ from IP-1 port if unused, so
Dante controller will not see undesired interfaces and no address conflict may happen.
Note2: The Dante board can be fitted afterwards.
2.3.6 SDI Embedding / De-Embedding.
Each SDI channel of a stage racer 2 frame is equipped with a 2 groups Embedder / De-
Embedder. Depending of the SDI port direction only one is active. For 12G/6G channels only the
first 3G stream is equipped with embedding / de-embedding resources. This logic is working for
48Khz embedded audio rates.
•
SDI port is an Input:
Up to 2 groups can be de-embedded and up to 8 audios can be selected and affected to the stage racer
internal audio bus and routed to any stage racer 2 audio output interface (Analog/Dante/Madi/SDI
Embedded). An SRC is used to adapt from Embedded audio rate to the Stage racer 2 internal audio
frequency.
•
SDI port is an Output:
Up to 2 groups can be Embedded and up to 8 audios can be sent by picking signals of various sources
(Analog/Dante/ Madi/SDI De-Embedded) present in the stage racer 2 network. An SRC is used to adapt the
Stage racer 2 internal audio frequency to the SDI clock locked 48Khz.
Caution: All SDI ports features de-embedders. On early FW embedder is not available on all ports (actually
only ports 4,5,10,11,16,17 and 23 do have).
