System Description .......................................................................
The Digico D5 console consists of a Worksurface, and 2 or 3 Input/Output Rack Units
All the console's audio inputs and outputs are connected to the Rack units, and each Rack units is con-
nected to the Worksurface via a pair of digital MADI links in either coaxial or within an Optocore optical
format. Each pair can carry up to 56 audio inputs and outputs.
There are 2 or 4 pairs of MADI connectors available on the Worksurface rear panel, including 2 bidirec-
tional optical MADI connectors allowing the connection of up to 3 Rack units and an alternative madi
connection. This gives a total capacity of 224 input and output sockets. However, the console is only able
to assign up to 64 or 96 audio channels (dependent on version), so not all the channels in a 4-madi system
can be used simultaneously.
Each Rack module contains input and output cards, which allow the same Rack unit to connect to different
types of analogue and digital audio devices.
As well as connecting the Worksurface MADI links to Rack Units, you can also connect them directly to
any other MADI equipped device, such as a digital multitrack recorder.
Introduction
Welcome to the Digico D5 Installation and connection manual. This manual is provided for purchasers of
the D5, in order to help their installation and connection of their new console.
Digico hope that this manual answers all the questions which may be asked by system designers and
installers, but should there be any issues unresolved for your particular installation, the local distributor or
the factory will be pleased to assist.
In general the installation of a D5 presents no problems which are significantly different from those of any
other large format live sound console when used exclusively for analogue systems and when used in
digital systems, is not significantly different from other digital consoles.
The Worksurface ...........................................................................
The D5 Worksurface is in many ways very similar to any large analogue mixing console. One key differ-
ence, however, is that no analogue signals are connected directly to the worksurface - all analogue I/O is
via the Rack units. The Worksurface rear panel does include a number of signal connectors, but these
should be used only for synchronisation, not for audio I/O.
The Worksurface is supplied in one chassis size, for 24 input + 16 master section faders.
Console Power Supply and Cooling ...........................................
Unlike most analogue consoles, the D5 Worksurface is powered directly from the mains, with no external
supply unit. The internal mains supplies are highly efficient and require no forced cooling, which means
that the Worksurface is silent in operation. However, it is important that convection airflow to the finned
heatsinks on the rear of the Worksurface are not restricted in any way. This heatsink normally runs at
around 25C above ambient temperature, and will be hot to the touch, though not hazardous. Note there are
2 x IEC mains inlets for the dual redundent supplies.
Worksurface Connections ............................................................
Apart from headphones and remote talkback, no audio is connected to the worksurface. Sync and control
connections are detailed later in this manual.
Headphone Connections ..............................................................
There are 2 parallel heaphone connectors with a 1/4" (6.3mm) stereo jack at each end of the console under
the armrest. These will drive down to 8 ohm loads, but note there is considerable power/voltage available
at low impedance. External volume limiting should be provided where required by local regulations.
Keyboard...................................................................................
The Worksurface unit includes a small computer keyboard with integral trackerball. This is fitted to a
slide-out tray which is set into to the bottom of the console.
Lighting...................................................................................
The worksurface includes an innovative illumination system comprising a series of white LED's in an
adjustable fully shaded fitting along the full length of the meterbridge. The brightness is adjustable by
an on screen control. There is no need for provision of addition lighting in normal applications.
