Vi5000/7000 User Manual 4.2: LOCAL RACK
HARDWARE > LOCAL RACK
The rack consists of a 6U processing and I/O unit, developed by Studer, called the SCore. Below this is a 3U low-
noise cooling fan unit. There is also an Active Breakout Unit, which provides direct audio connections for local use and
for connection to the Control Surface, and a another Breakout Panel for convenient MADI connections for
Stageboxes. The SCore itself consists of two sections: the upper 3U section houses the DSP mixing core, and the
lower 3U section houses the local audio I/O and also the connections to the remote Stage Box.
The audio processing inside the SCore is independent of the control surface. This means that the audio will continue
to pass even if the control surface is switched off or disconnected from the core.
How It Works
The control surface sends control data to the Bridge Card, which is a communication and processing hub situated in
the centre of the top 3U section of the Local Rack. The Bridge Card interprets the control data and sends internal data
to the five or eight DSP Pro cards and the FX Card. These cards actually process the audio. The audio input and out-
put connections to the DSP cards are made via short CAT 5 patch cables, which connect the DSP cards with the I/O
rack in the lower 3U section of the core.
