Cadac consoles are designed to allow th e use of two independent power supply systems 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
‘loa d’ is sh ar ed b etw e en th e “ m ai n” a nd “ bac ku p” PS U’s. I f a f a ul t o cc ur s in on e o f t he
power units ( c ausing it to ‘shut-down’), the remaining power unit will power the console.
For smaller B-Type consoles (consuming no more than 44A), it is possible to use the
8400 PSU. See 1. 3. 7 8 400 switch-mode power supp ly uni t.
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
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.

The a.c.-input connectors on each power supply unit have three conductors: ‘LIVE’
(brown), ‘NEUTRAL’ (blue) and ‘EARTH’ (yellow/green). For safety and electromagnetic compatibility considerations, it is essential that the ‘EARTH’ conductor is connected on all PSUs
continuous c ircuit to the “zero-signal reference potential” point in t he building. The
ZSRP point in a building is usually found near the place where the a.c. ‘mains’ supply
enters the building (often referred to as the “MAIN GROUND REFERENCE EARTH
ELECTRODE SYSTEM”). The basic concept for correct a.c. mains wiring distribution
is shown in figure 1-1. If you need further information about this complex subject,
please refer to “Grounding Systems and their Implementation” by Charles Atkinson

If replacing a switch-mode power supply unit is required, please note the following:
Make sure that the power supply s ystem’s power switches are in t he position
■■■■
OFF and disconnected from the mains.
The work should only be carried out by a suitably qualified electrician.
■■■■
Be careful to observe corr ect polarity when connecting the new PSU.
■■■■
Note that a console must never have one voltage without the other, f or exam ple
■■■■
+18V must never be fed into the console without -18V.
When switching the power supply system back ON after replacement has taken
place, make sure that both LEDs on the front of the PSU-system come on. If only
one LED comes on, let go of the ON push-button immediately. Failure to do so may
lead to fire hazar d and major damage to th e console.
NO TE:
Under no circumstances, should the 8019 or 8020

CADAC con s oles are designed to work continuously with two power supply systems
- ‘mai n’ an d ‘b ac k u p’ . The ‘ma in ’ po w er sup ply pai r ( 1 off ‘1 8v ’ un it an d 1 of f 13V/ 48 V
unit ) are designated ‘System 1’. The ‘backup’ power supply pair (1 off ‘18V’ unit and
1 off 13V/48V unit) are designated ‘System 2’.
On each power s upply, tu rn all AC input switches to the ON-position.
Start the ±18 V an d 13V/ 4 8V PSU s (in one PSU syst em) simu lt an eo us ly, by pressing
and holding the START-buttons until you hear the relay click. The CCM will cycle
through its self-test routines and any Master Mute swit ches previously selected will
be set ON, thus protecting external equipment from possible DC pu lses when the
±18V PSUs ar e sta r ted.
Repeat for PSU system 2. If you cannot start the PSUs simultaneously, start the 13V/
48V first. However, do NOT operate the console for long periods without all power
lines on.

This group of buttons provides a quick and convenient way of setting the console
autom ation system to both re cord and control the mo vement sequences of motor
faders.
The to p left pair control the play /pause an d stop for the firs t dynamic sequence
(dynamic A) in a Cue.
The top right pair control the play/pause and st op for the second dynamic sequence
(dynamic B) in a Cue.
Both dynamics can be run simultaneously in the same cue.
Accidental movement of the motor faders can be prevented by use of the ALL SFE
and ALL RDY keys. In SAFE mode, touching the faders knob will have no impact on
the recorded sequence. In READY mode touching the fader knob will cause the
motor fader logic to toggle between READY and WRITE modes.
Therefore , editing of a reco rded sequence can be performed for as long as the fader
knob is actually touched and the fader remains in the READY mode.

Before the console automation can be used, all faders and programmable modules
must be mapped. Each Map is stored in non-volatile memory within the CCM. Mapping operations should only need to be performed if the layout of the modules within
the frame have been changed. A new console is always mapped by CADAC before it
leaves th e factory.
Each module po sition in a frame is i dentified by a unique n umber (the address). This
number is set by a combinati on of a small PCB fixed to the f rame beneath each module and the frame number switch at the back of a frame. As each fader i s connecte d
to a module, it too can be given a unique address.

The in put channel has a single input capable of accepti ng a wide range of input
sources. The input signal may be routed to any or all of the 28 groups available on
the system. A separate Direct Output can be provided.
The equalize r and LP/HP filters can be switched in and ou t separately. Each EQ section has controls for ±18dB cut and boost, variable frequency and Q. There are four
EQ bands.
The normal PFL and MUTE switches are situated near the fader section of the module, above and below the ‘DC Group” display.

Stereo mode selection is a ‘global mode’ controlled from the
CCM (see 2 Central Control Module 7896).
E.g. If Auxiliary 1 is selected ‘STEREO’ on the CCM, the “SET” LED in the AUX1

Q value gives a wide bandwidth. This means that a relatively large range of frequencies (either side of the centre frequency) have the cut/boost applied. A the Q value is
increased, the bandwidth is reduced, so that a very much smaller range of frequencies have c ut/boost applied.

The Grand Master Group module is a specialized version of the standard M-Type
group module 7756.
Each Aux Group section has an additional input that allows a line level signal to be
injected into its mixing amplifier; an output level fader with associated 20 segment
LED meter; switches for Insert, Inject, Matrix Pre, Mute and Listen (monitor). Routing
to the 24 Matrix Groups is done via 24 push button switch es labelle d 1A/B to12A/B.
All gr ou ps us e the sam e f r ont p an el an d el e ctr oni cs . T he di ff e r en t gr ou p m od ul es ar e
denoted by individual Aux Gr oup numbering on their respective MUTE switches. Mixing bus coding is done by use of “Bus Coding” link boards and the DC Master fader
number is set by DIL switches on the motherboard (see CADAC schematic drawing
7767 in the “Drawing Set”.
Following pages describe the grand master group module in detail.

A Matrix module contains 4 Matr ix Groups arranged in two sections. Each section
has two matrix groups, designated “A” and “B”. A total of 24 Matrix Groups (1A to
12A, 1B to 12B) can be includ ed in a B-system so that a fully fitted console would
have 6 matrix modules.
All matrix have a common fr ont panel and mother board. An ‘odd’ numbered Matrix
Group is in the lower section of the module and an ‘even’ numbered Matrix Group in
the up per section. A single Matrix Group is designated by a printed number on the
MUTE switch cap, combined with a letter “A” or “B” on the front panel.
