WORKING SAFELY WITH SOUND
Although your new console will not make any noise until you feed it signals, it has the capability to produce sounds which when monitored through a PA system or headphones can damage hearing over time.
The table below is taken from the Occupational Safety & Health Administration directive on Occupational
noise exposure (1926.52):
PERMISSABLE NOISE EXPOSURE
DURATION PER DAY, HOURSSOUND LEVEL dBA SLOW RESPONSE

<0.25115
Conforming to this directive will minimise the risk of hearing damage caused by long listening periods. A
simple rule to follow is the longer you listen the lower the average volume should be.
Please take care when working with your audio - if you are manipulating controls which you don’t understand (which we all do when we are learning), make sure your monitors are turned down. Remember that
your ears are the most important tool of your trade, look after them, and they will look after you.
Most importantly - don’t be afraid to experiment to find out how each parameter affects the sound - this
will extend your creativity and help you to get the best results.

LOCAL RACK
Local Rack Description
The Local Rack is the audio ‘brain’ of the Soundcraft Vi4™, 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.

Local Rack Rear
The rear of the Local Rack gives access to the cards in the card frame, and to the XLR breakout box.
Primary Power Supply
The primary power supply connects directly to the IEC inlet and provides a full range ac inlet, converting
100V to 240V ac to 24V dc. The Local Rack can hold up to two power supplies, providing seamless redundancy for those that require it. The rack fan control connection is also provided by one of the power supplies.
XLR Breakout Box
This provides connectors for analogue and AES/EBU audio, and interfaces to the Line In cards, Line Out
cards, Mic card and AES/EBU Card within the Local Rack card frame. All the connectors on the Breakout
Box are of the XLR type.
It is possible to order the console without this part, in this case the user will have to provide suitable
cabling and connectors to interface with the appropriate Local Rack cards. A complete pin list is given later
in this chapter.
The Breakout Box connector labelling references are used by the patching system (see chapter 11) when
the user wishes to patch the connectors to input channels or output busses.
Audio I/O Cards
The following cards are supported.
1 X Mic/Line Input card providing four electronically balanced Mic/Line Input channels, each
with digitally-controlled analogue gain, a 80Hz low-cut filter, and phantom power.
2 X Line Input cards, each providing eight line input channels.
3 X Line Output cards, each providing eight line output channels.
1 X AES I/O card, providing 16 AES input channels and 16 AES output channels.
1 X MADI Stage Box interface card ( normally Cat 5, but it can optionally be replaced by an
optical MADI card).
1 X Optical MADI card, providing 64 MADI input and 64 MADI output channels.
See page 2-10 for more details.
