LOCAL RACK

Local Rack Description

The Local Rack is the audio 'brain' of the Soundcraft Vi6™, it contains the DSP mixing processor and the
local I/O connections.
The rack consists of a 6U processing and I/O unit, developed by Studer, called the S-Core. Below this is a
4U low-noise cooling fan unit. The S-Core 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 S-Core 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 two DSP Pro cards and the FX Card (when fitted). These cards actually
process the audio. The audio input and output connections to the DSP cards are made via 4 short CAT 5
patch cables, which connect the DSP cards with the I/O rack in the lower 3U section of the core.

Front Panel

The front panel contains the Status LED array.
Figure 2-5: Status LEDs.
These LEDs give an at-a-glance indication that the Local Rack is functioning correctly, or that an error
condition has occured. An illuminated green LED indicates the presence of a card, an illuminated red LED
warns of a card error.
Note that there is a RECONFIG button behind a small hole at the bottom right of the panel. When pressed
with a small screwdriver or similar a reset is applied to the lower row of cards in the local rack: this will
force a re-polling of the loaded cards to reconfigure the console. This needs to be done only if the card
configuration has been changed.
