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.

The a.c.-input connectors on each power supply unit have three conductors: ‘LIVE’
(brown), ‘NEUTRAL’ (blue) and ‘EARTH’ (yellow/green). For safety and electromag-
netic compatibility considerations, it is essential that the ‘EARTH’ conductor is con-
nected on all PSUs and the a.c. supply has an ‘EARTH’ conductor that has a
continuous circuit to the “zero-signal reference potential” point in the 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
Electromagnetic Compatibility
requirements (EMC Directive - 1996). Any RF noise
induced in the console frame(s) is directed to the “local” ZSRP, which is the metal-
work of the power supply units. In order to take full advantage of the “RF noise immu-
nity” capability of the CADAC system, PSU a.c. mains cables and the a.c. mains
supply EARTH conductor must be connected correctly.
41615 $&#SRZHU#UHTXLUHPHQWV
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. single-
phase 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 Con-
necting to a 3-phase outlet.
41616 6ZLWFK00RGH#3RZHU#6XSSO\#8QLWV
CADAC 8019 and 8020 switch-modepower supply units are designed to run from a

If replacing a switch-mode power supply unit is required, please note the following:
■
■■
■Make sure that the power supply system’s power switches are in the position
OFF and disconnected from the mains.
■
■■
■The work should only be carried out by a suitably qualified electrician.
■
■■
■Be careful to observe correct polarity when connecting the new PSU.
■
■■
■Note that a console must never have one voltage without the other, for example
+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 hazard and major damage to the console.
NOTE: 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 200-240V. Before connecting to any 3-phase outlet, please
refer to a qualified electrician 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 cor-
rect earth/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-phasepower outlet connector.
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, YEL-
LOW) 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
theEARTH(Yellow/Green) conductor on the“system1 “8020 unit tothe SAFETY
EARTH (Yellow/Green) terminal on the 3-phase power outlet connector.
5. Repeat 1-4 for the “system 2” power units.

1. Using a short U-LINK cable (supplied), connect one of the outputs on the ±18V
PSU to one of the outputs on the +13V/+48V PSU in the “SYSTEM 1" power
supply rack. This operation “links” the d/c outputs on both power supply units in
the rack so that ±18V, +13V and +48V is available on all remaining output con-
nectors on either power unit.
2. Connect the second short “U-LINK” cable (supplied)between the ±18V PSU and
the +13V/+48V PSU’s in the “SYSTEM 2" power supply rack.

Each 8019 and 8020 switch-mode power supply is fitted with a front panel mounted 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 “system” pair 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.
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-pole switch for controlling
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’ free 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.
Great care must be taken with the wiring of the switch(es) to ensure that no short-cir-
cuits can occur between any two power supply units.

The 8400 unit is based on one POWER ONE RPMS-ETETGDGD1ETK Power block,
with additional circuitry as shown on CADAC drawing number C3.8397.
4161; 5HPRWH#VWDUW#RI#;733#368
Each 8400 switch-mode power supply provides the following outputs: 13v, ±18v and
48v. Each PSU is fitted with a front panel mounted 9-way 'D-type’ connector labelled
‘Connections for Remote 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 cir-
cuit 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-
glepole 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’ free 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 switch(es) are
mounted.

If the console is used in a multi-frame configuration then the busses need to be con-
nected in a ‘daisy chain’ fashion.
Each end
of a frame has seven bus connectors -
four audio and two data busses plus fader bus (see fig 1-13). The bus cables are
simply linked between similar connectors on the end of the nearest frame.
Make sure that each frame has its “Frame Select” switch set to a different number.
See also appendix A. Important information regarding EMC.

When motor faders are used in extension frames, a 9-way “FADER COMMS” cable
must be connected between the CCM connectors shown (see fig 1-3) and the
COMMS input on the extension frame rear panel.
Extension frames fitted with motor-faders require control data from the CCM. Three
9-pin female connectors Three 9-pin female connectors located on the rear panel of
the CCM are connected directly to the extension frame using the supplied ‘fader
comms’ cable. The frame containing the CCM sends motor data fader data, via the
7303 interface module (always mounted directly belowthe CCM on J-type consoles).
Thus, a 3 frame console would require two “FADER COMMS” cables:
“FADER COMMS on EXTENSION FRAME 1 TO “FADER COMMS 2” on CCM
“FADER COMMS on EXTENSION FRAME 2 TO “FADER COMMS 3” on CCM

PFL mixing amplifiers are located in the “Oscillator/Communications” module. There
are two PFL outputs:
■
■■
■PFL Direct is a line level output that appears on an XLR 3-32 connector on the
rear panel of the OSC/Comms module, labelled “PFL DIRECT”;
■
■■
■PFL to Headphones is a high level output suitable for driving headphones that
appears on an XLR 3-32 connector and a TRS jack socket connector on the rear
panel of the OSC/Comms module, labelled “PFL TO HP”.
The PFL to Headphones signal can be connected to the TRS jack sockets mounted
on the front of the console frame by using the “OSC/COMM TO FRAME” cable sup-
plied. This cable has a male XLR 3-pin connector on one end and a female XLR 3-
pinon the other end. Connect one end of the “Oscillator/Communications” module’s
“PFL TO HP” connector and the other end to the rear frame connector labelled

Additional inter-frame connections are required to enable the PFL signals from mod-
ules in extension (side) frames to be monitored. Use the cable(s) labelled “PFL
FRAME TO FRAME” to interconnect two or more frames:
■
■■
■Connect one end of a “PFL FRAME TO FRAME” cable to the connector labelled
“TO NEXT FRAME” on the console frame containing the “Osc/Communications”
module.

Surface illumination of the console is provided bythe use of two or more “Littlite”
units that plug into the top bar of the console frame. Control for the “Littlites” - on/off
and intensity - is located on the “Oscillator/Communications” module. The variable
voltage power supply is mounted inside the console frame.
Two cables are required to interconnect the “Littlite” controls, the variable voltage
power supply and the lamp units.
