General Precautions v
Revision B2005-2 B-Type
*HQHUDO#3UHFDXWLRQV
'DPDJH
Do not place heavy objects on the control surface, expose it to sharp objects or han-
dle the console in any way that may cause damage e.g. rough handling and/or
excessive vibration.
(QYLURQPHQW
Do not subject the equipment to dirt, dust, heat or vibration during operation or stor-
age. Never expose the console to rain or moisture in any form. Should the console
become wet, turn it off and disconnect from mains without further delay. The console
should be given sufficient time to dry out, before recommencing operation.
&OHDQLQJ
When cleaning the console, never use chemicals, abrasive substances or solvents.
The console control panels should be cleaned using a soft brush and a dry lint-free
cloth. For persistent marks, use a soft cloth and isopropyl alcohol. Switches and
potentiometers do NOT require cleaning or lubrication. For faders, see below.
7UDQVSRUW
Transport the console in its purpose built flight-case; whilst at the same time taking
precautions to protect the control surface from any damage. Always make sure ade-
quate manpower is available and correct lifting methods are taken when moving the
console.
6DIHW\#,QVWUXFWLRQV
Read the following before using the equipment:
,QVWUXFWLRQV
Keep these instructions for future reference. Follow all warnings in this manual and
those printed on the power supply units.
,QVWDOODWLRQ
The console must be installed following the guide lines in this manual. Never connect
power amplifier outputs directly to the console. Connectors and plugs must never be
used for any other purpose than for what they are intended.
&RYHUV
Never use the power supply units without covers fitted. All service work must be car-
ried out by qualified personnel only.
3RZHU
The power supply units must always be connected to correctly rated mains power as
referred to in this manual and marked on the power supply units. The power supply
units must, at all times, be connected to the local mains power supply using the sup-
plied powercord.In cases where the supplied plug does notfit, aqualifiedelectrician
must be consulted.
3RZHU#FRUG
The power cord must be routed in such a way that the risks of accidentally stepping
on it, stretching it or it being pinched, are minimized.
:DUQLQJ
THIS EQUIPMENT MUST BE EARTHED !
0RLVWXUH
In order to minimize risks of fire hazards and/or electric shock, the power supply unit
must never be exposed to moisture or water in any form; orbe used in a dampor wet
environment. Neverplace liquid containers, such as for instance coffee/tea mugs, on
the power supply unit, so as to avoid spillage into openings.
9HQWLODWLRQ
Ventilation slots on the power supply or the console must never be covered or in any
other way obstructed. Air flow required for safe operation may otherwise be
restricted. Where the console is to be operated in its flight-case, then this must be
located in such a way that it allows for proper ventilation.
6HUYLFH
Refer servicing to qualified technical personnel only.

Introduction vii
Revision B2005-2 B-Type
,QWURGXFWLRQ
CADAC consoles have an impressive track record when it comes to delivering fault-
less performance night after night, year after year, on almost every imaginable type
of production. International musicals, the world’s most prestigious theatres and
opera houses, major awards ceremonies - for critical applications where quality is
paramount, the CADAC name is synonymous with top quality audio within a rugged,
reliable package.
The introduction of B-Type Live Broadcast Console is CADAC’s first dedicated desk
for live studio applications. it was designed in response to the broadcast industry’s
requirement for a more versatile, higher quality console that could provide an inte-
grated solution - taking up a smaller footprint whilst offering a much more powerful
matrix and flexible output options. It provides crucial information at a glance -
switches are illuminated for clarity in low light conditions, assignable VCA masters
are labelled with assignable alpha-numeric displays and modules can be put in any
position in the frame to suit the operator’s requirements.
The B-Type is designed to meet the needs of modern live broadcast programming -
offering modularity witheasy upgradeability, protecting your investment for the future.
All without compromising the renowned CADAC reputation for superior audio quality,
reliability and enduring performance.

The B-Type features CADAC’s unique frame design which allow users to put any
module in any position,thus configuring the console to suit the project in hand. Each
module is fitted with XLR connectors and jack sockets on the rear vertical face,
enabling the module to be moved quickly and easily.
The B-Type module’s design features a motherboard, with plug-in daughter boards
for all audio and digital control functions. This ensures servicing simplicity and fast
replacement of any faulty component. Each module maybe plugged into any posi-
tion in the console frame, by means of top quality two-part connector system, which
is designed as a mating pair to provide excellent mechanical and electrical reliability.
A rail system is used to guideeach module into its correctposition. Also, the console
design allows modules to be removed or inserted without powering down.

Cadac consoles are designed to allow the use of two independent power supply sys-
tems in a redundant configuration – “main” and “backup”. Both sets of power supply
units are used to power the console system so that under normal conditions, the
‘load’is shared between the “main” and “backup” PSU’s.Ifa fault occurs in one of the
power units (causing it to ‘shut-down’), the remaining power unit will power the con-
sole.
For smaller B-Type consoles (consuming no more than 44A), it is possible to use the
8400 PSU. See 1.3.7 8400 switch-mode power supply unit.
One ±18V PSU and one +13V/+48V PSU is referred to as a “PSU System”.
Designate one pair of power supply units as “SYSTEM 1" and the other as “SYSTEM
2". PSU System 1 and PSU System 2 should be connected to the same
phase
and
on the same ‘spur’, wherever possible. In situations where it is necessary to provide
a separate ‘feed’ to each PSU system pair, make sure that the cable lengths are the
same. This is to minimize any induced a.c. power input noise by ensuring that the
“EARTH IMPEDANCE” is the same for both PSU systems.
