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
fo r all audio and digital control functions. This ensures servicing simplicity and fast
replacement of any faulty component. Each module may be plugged into any p osi­tion 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 guide each module into its correct position. Also, the console
design allows modules to be removed or inserted without powering down.

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.

Connecting the mixer systems 1-3

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
and Philip Giddins published in the AES Journal Vol. 43, No. 6 – June 1995.
The grounding scheme in CADAC consoles is designed to meet the rigorous EEC

CADAC power supply units are designed to run from a minimum of 208 V up to a
maximum of 260V, 50/60Hz a.c. In many parts of the world the normal a.c. single­phase supply is 100-127V, this means that the CADAC power supply units must be
connected across two of the phases in the three-phase a.c. supply, see 1.3.4 Con­necting to a 3-phase outlet.

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
PSU be used without a SAFETY EARTH connection. Failure
to follow this instruction is both a fire and safety hazard.

Connection to a 3-phase outlet is required on sites where the system voltage
between any one of the phases and neutral is 100-127V and the voltage between
any two of the phases is 20 0-240V. Before connecting to any 3-phase outlet, please
refer to a qualified electricia n who understands your particular installation and the
local safety and wiring regulations. Under no circumstances should the 8019 and
8020 switch-mode power supply units be operated without the green/yellow safety
earth conductor connected to the building safety earth conductor system. Each
power unit is equipped with an input supply filter whose reference ground conductor
is the chassis. Failure to connect the green/yellow safety earth conductor to the cor­rect eart h/ground building reference is a safety and fire hazard.

1. Connect the LIVE (Brown) conductor on the “system 1” 8019 unit to the phase 1
(L1, RED) terminal on the 3-phase power outlet connecto r.

2. Connect the NEUTRAL (Blue) conductor on the “system 1” 8019 unit and the
LIVE (Brown) conductor on the “system 1” 8020 unit to the Phase 2 (L2, YEL­LOW) terminal on the 3-phase power outlet connector.

3. Connect the NEUTRAL (Blue) conductor on the “system 1” 8020 unit to the
Phase 3 (L3, BLUE) terminal on the 3-phase power outlet connector.

4. Connect the EARTH (Yellow/Green) conductor on the “system 1” 8019 unit and

Each 801 9 and 8 02 0 s w it ch- mod e p o we r supp ly is fi t ted wi th a f ron t p an el mo un ted 9
way ‘D-type’ connector. This connector is labelled “Connections for Remote Start”.
You may connect a single remote start switch to each unit, have one switch start a
“system” pair, or wire up a single switch to start “system 1” and “system 2” all at the
same time.

Fig 1-5 applies to 8019 and 8020 PSUs up to serial number 34949 and shows the
circuit for starting up a “s ystem” pair with a single switch. This has pro ved to be the
most popular method of connecting the remote start facility. This circuit can easily be
extended to provide a single switch remote four all four PSUs if required.

For 8019 and 8020 PSUs from serial number 34950 onwards, see fig 1-6 and 1-7.

NOTE:

The remote must be a ‘momentary’ type. You will need a two-pole switch for a

■■■■

single PSU, a four-pole switch for a “system” pair, or a six-pol e switch for con trolling
all four units.

The remote switch(es) must be mounted on a metal panel.

■■■■

Use shielded cable for the remote switch wiring.

■■■■

The 9-way ‘D-type’ f ree plug must have a conductive shell. This is to ensure that

■■■■

the cable shield connects directly to the PSU unit chassis.

Connect the cable shield to the metal panel where the remote start switch(es)

■■■■

are mounted.

FIG 1-10. 8400 power supply unit.

CADAC 8400 switch-mode power supply units are designed to run from a minimum
of 208V up to a maximum of 260V a.c, 50/60Hz.

The 84 00 is rated thus +13V@92A, ±18V@44A and 48V@5A.

The a .c. input is connected to the PSU via a 3-core cable, CMA reference 3183TQ –
BASEC approved, rated at 20A.

The 8400 unit is based on one POWER ONE RPMS-ETETGDGD1ETK Pow er block,
with additional circuitry as shown on CADAC drawin g number C3.8397.

4161; 5HPRWH#VWDUW#RI#;733#368

Each 8400 switch-mode power supply provides the follo wing outputs: 13v, ±18v and
48v. Each PSU is fitted with a front panel mounted 9-way 'D-type’ connector labelled
‘Connections for Remo te Start’. If a remote start facility is used, Power Failure and
Over-Temperature LEDs may also be fitted with the remote start switches if required.

Fig 3-15 shows the circuit for starting up a “system” with a single switch. This has
proved to be the most popular method of connecting the remote start facility. This cir­cuit can easily be extended to provide a single switch remote four all four PSUs if
required. If muliple switches are to be used, see fig 3-14.
NOTE:

The remote start switch must be a ‘momentary’ type. You can use 3 separate sin-

■■■■

gle pole switches for each Power Supply to turn on 13v,±18v and 48v outputs of the
PSU alternatively use one single pole for the whole lot.

The remote switch(es) must be mounted on a metal panel.

■■■■

Use shielded cable for the remote switch wiring.

■■■■

The 9-way ‘D-type’ f ree plug must have a conductive shell. This is to ensure that

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

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 HF frequency control allows you to sweep throu gh the range 1.5kHz to 15kHz.

The Q con t rol v arie s th e ba nd wid t h of the E Q se ct io n in th e r a ng e Q= 1 to Q =3. A l ow
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

B-Type Revision B2005-2

Group Module 7756 6-1

9 *URXS#0RGXOH#::89

The B-Type console has 28 Aux Group and 24 Matrix Group b usses. A s tandard
group module contains 2 Aux Groups (A and B). Since each Aux Group is wired to an
output connector, 52 separate outputs are available on a fully fitted console.

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 to 12A/B.

All group modules use the same front pa nel and elec tronics. The different group
modules are denoted by ind ividual Aux Group numbering on their respective MUTE
switches. Mix in g bus cod i n g is do ne by use of “Bus Coding ” link boards an d t he DC
master fader number is set by DIL switc hes on the mo ther board (see CADAC sche­matic drawi ng 7767 in t he ‘Drawing Set”).

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.

Matrix Module 7770 8-1

; 0DWUL[#0RGXOH#:::3

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.

Following pages describes the mat rix module 7770 in detail.

All Matrix Groups have a Send and Return break-jack facility placed after the mixing
amplifier and before the output level fader. This is to allow the Matrix Group signal to
be sent out to, and return ed from an external processor unit. The INSERT switch is
programmable, and its ‘condition’ can be recorded in a cue. A relay is used to switch
