The CADAC marque has an unequalled reputation for audio performance, reliability
and eng ineering excell ence - qualities reflected in a product r ange which encom­passes the full spectrum of live sound applications - from rock’n’roll to theatre, from
musicals to opera. Focusing solely on the demanding live sound sector, CADAC con­soles deliver quality without compromise.

The CADAC J-Type has gained benchmark status as the worl d’s leading cons ole for
major musical pro ductions, based on it s combination of exceptional audio quality,
reliability and flex ibility. The industry standard in London’s West End and on Broad­way, the J-Type credit list includes the world’s most successful and longest running
musicals - Miss Saigon, Les Miserables, Disney’s Lion King, Beauty & The Beast,
Phantom of the Opera and Su nset Boulevard, to name a few.

Resisting the pressures of cost-engineering and high-speed production. CADAC
consol e s are de si gn ed an d bu il t to t he hi gh es t s tan dar d s , ens ur in g t hat “ the q ua li t y is
remains long aft er the cost is forgot ten”. A CADAC console is sound investment, cre­ated to give flawless performances, night after night, and year after year.

Being the first console to feature CADAC ’s unique frame design, the CADAC J-Type
allo ws users to put any module i n any position, thus allowing for fast configuration of
the console to sui t the project in hand. Internal audio bu ssing is bal anced and uses
ribbon cables with “floating” connectors fitted on steel cradles. Data busses use ded­icated ribbon cable. All power bussing is rated at 40A per rail. Frame-mounted input
connectors include diode-mixed power inlets, earth points, headphone and Littlite
conne ctor s . Th e f ra mes in co rpor at e m ult ip le co olin g fans wi th a 5- spee d c on tro l. An y
frame size may be specified 25 to 63 modules wide.

The CADAC J-Type has an impressive range of input modules to choose from,
underlining its performance capabilities - original mono inputs can be combined with
progr a mmab l e du al in put a nd st ereo cha nn el s to a chi eve the prec is e r ou tin g an d mi x
required for every cue. This is complemen ted by th e J-Type’s versatile matrix - with
up to 16 sub and 32 matrix group ou tputs.

The J-Type programmable modules offers extensive automation facilities. Designed
for use alongside existing J-Type modules, all pot and sw itch settings for each cue
can b e stored and recalled during a performance - including those of the routing , EQ
and insert poin ts.

This manual provides the user with information on the installation of the J-Type con­sole t ogether wi th a concise console operating guide and functional descriptions of
all the avai lable mo dules and faders. Used in con junction with the sophisticated con­sole cue automation system - the Sound Automation Manager (SAM), running on a
Windows ® operating system - has produced a sound mixing and control system that
provides a complete sound control system that is easy to programme whilst provid­ing th e traditional CADAC sound and performance quality.

The J-Type was the first console to feature 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 modu le is fitt ed with XLR connectors and jack sockets on the
rear vertical face, enabling the module to be moved quickly and easily.

The J-Type module’s design features a mo therboard, with plug-in daughter board s
for all audio and digital control functions. This ensures servicing simplicity and fast
replacement of any faulty component. Each module may be plugged into any posi­tion 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 reliabil ity.

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 desi gned to al low the use of tw o indepe ndent power supply sys­tems in a redundant configuration – “m ain” and “backup”. Both sets of power su pply
units are used to power the console system so that under normal conditions, the
‘loa d’ is sh ar ed bet w een th e “ m ai n” a nd “backup” P SU ’s. I f a fault o cc ur s i n on e of t h e
power units (c ausing it to ‘shut-down’), the remaining power unit will power the con­sole.

For smaller J -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.

Revision J2005-2 J-Type

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 i s essential that the ‘EARTH’ conductor i s con­nected on all PSUs

and

the a.c. supply has an ‘E ARTH’ conductor that has a
continuous circuit to the “zero-signal reference pot e ntial” 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

Electromagne tic Compatibility

requirements (EMC Directive - 1996 ). Any RF noise
induced in the console frame(s) is directed to the “local” ZSRP, which is the metal­work of the power supply units. In order to take full advantage of the “RF noise immu­nity” capability of the CADAC s ystem, 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. 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.

41616 6ZLWFK00RGH#3RZHU#6XSSO\#8QLWV

CADAC 801 9 and 8020 switch-mode power supply units are de signed to run from a
minimum of 208V up to a maximum of 260V a.c, 50/60Hz.
The 80 19 “18 V ” uni t is r ate d at 10 0A per r a il an d th e 8 020 “1 3V” un it is r at ed at 100 A.

If replacing a switch-mode power supply unit is required, please note the following:

■■■■

Make sure that the power supply system’s power switc hes are in the position

OFF an d disconnected from the mains.

■■■■

The work should on ly be carried out by a suitably qua lified electrician.

■■■■

Be careful to observe correct polarity when connecting the new PSU.

■■■■

Note that a console must never have on e volta ge 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 th e 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 t wo 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 cor­rect 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, R ED ) terminal on the 3-ph ase power outlet co nnector.

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 “syste m 1” 8019 unit and
the EAR T H ( Yellow/ Gre en ) co nd uc tor on the “sys te m1 “8 02 0 un it to the S A FET Y
EARTH (Yellow/Gr een) terminal on the 3-phase power outlet connector.

Each 801 9 and 8 02 0 s w itch - mod e p o we r su pp ly is fi tte d wit h a f ron t p an el mo unte d 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 t o start “system 1” and “system 2” all at the
same time .

Fig 1-7 applies to 8019 and 8020 PSUs up to serial number 34949 and shows the
circ uit 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
ext ended to provide a s ingle switch remote for all four PSUs if required.

For 8019 and 8020 PSUs from serial number 34950 onwards, see fig 1-8 and 1-9.

NOTE:

■■■■

The remote must be a ‘momentary’ type. You will need a two-pole switch for a
singl e PSU, a four-pole swit ch 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-cir­cuits can occur between any two power supply units .

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

The 8400 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 Power block,
with additiona l circuitry as s hown 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 fron t panel mo unted 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 cir­cuit can easily be exte nded to provide a single switch remote for all four PSUs if
required. If muliple switches are to be us ed, see fig 3-14.

NOTE:

■■■■

The remote start switch must be a ‘momentary’ type. You can use 3 separate sin­gle po le switches for each Power Supply to turn on 13v,±18v and 48v outputs of the
PSU alternatively use one single pole for all voltages.

■■■■

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-fram e configuration then the busses need to be con­nected in a ‘daisy chain’ fashion.

Each end

of a frame has seven bus connectors ­four audio and two data busses plus fader bus . 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.

Extension frames fitted w ith motor-faders require control dat a from the CCM. Three
9-pin female connectors Three 9-pin female connectors located on the rear panel of
the CCM are connected direct ly

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 mou nted directly below the CCM on J-type consoles).

Thus, a 3 frame console wou ld requir e two “FADER COMMS” cabl es:

Figure 1-7 shows the rear panels of the power supply units in a single PSU system.
Under normal conditions, the 0v and Mains-Earth terminals can be connected on
both PSU systems. However, if the a.c. input lines to each pair of PSU’s has a differ­ent length, you may find that the 0v and Mains-Earth terminals can only be linked on

one

set of power suppli es, for minimum system noise.

The 0v or FRAME terminals on a PS U need

not

be directly connected to the 0v an d/
or FRAME connections on con s ole frames. The shielded po wer supply cables are
connected to the frame at both ends.

In addition to the terminals on the back of the PSUs, there are

0v, GND

and

FRAME

connections on the rear of each console frame. The shorting-bar link between the 0v,
GND and “ FRAME” term inals on each frame

must

be connected. For minimum
noise, the large diameter ‘frame-link’ cables (supplied with multi-frame consoles ),
must be connected. Always make sure that ‘frame-link’ cable nuts are tightened
again s t the copper bar.

The 0v, GND and FRAME terminals are linked in the factory with a copper bar. This
bar should ne ver be removed when the console is in normal use . Note that

Phantom

Power

cannot be delivered from the input modules to the 48V bus if the copper bar is
missing, because the screened microphone input cables will not be terminat ed. It
may also cause damage to the motor faders.

dynami cs can run sim ultaneously. The mo tor faders can be set to safe and ready
mode respectively. In safe mode, touching the fader knob will have no impact on the
recorded sequence. In ready mode, touching the fader knob will cause the motor
fader to toggle between ready and write mode. Thus, editing of the recor ded
seque nce (dynamic A only) goes on for as long as the fader knob is actually touched
and the fader remains in ready mode.

############

PLA Y/P A USE (1)

Plays, pauses or continues a recorded sequence of motor fader
movements associated with dynamic A. If recording is enabled with the push-button
(8), then this button starts either a new recording, or starts an update of an existing
dynamic.

PLA Y/P A USE (2)

Plays, pauses or continues a recorded sequence of motor fader

movements associated with dynamic B.

STOP (3, 4 )

Stops the recorded sequence of motor fader movement s.

SET READ Y (5)

This mode allows individual faders to be “toggled” between safe and

ready mode by touching the fader kn ob.

ALL READ Y (6)

Sets all motor faders to ready mode.

ALL SAFE (7)

Sets all motor faders to safe mode.

RECORDING ENABLED (8)

Prepares the computer for recording of a dynamic

sequence. Pressing button (1) starts the actual recording.

Before the console automation can be used, all faders and programmable modules
must be mapped. Each Map is stored in non- volatile memory with in the CCM. Map­ping o perations should only need t o be performed if the layout of the modules wi thin
the frame have been changed. A new console is al ways mapped by CADAC before it
leaves the factory.

Each module position in a frame is i dentified by a unique n umber (the address). This
number is set by a combination of a small PCB fixed to the frame beneath each mod­ule an d the frame number switch at the back of a frame. As each fader is connected
to a module, it too can be given a uniq ue address.

By themselves these numbers are not particularly “user- friendly” , for example the
first programmable router module may be in frame position 28, but it is preferable to
call it “router 1" not “router 28". The Maps therefore allow the user to give any partic­ular fader or module an identifying number that is more appropriate than the address
fix ed by the hardwar e. The CCM will then convert between the address and the new
module (or fader) number automatically.

The

Enable

switches on the CCM have a “second function” capability. This allows

you to over ride the setting of one or both MIDI ports and/or the Events for one Cue
only.

When “2nd Function on” is selected, the software will interpret a “double key press”
as an instruction to reverse the condition of the Ena ble switch for one Cue only.

Example: MIDI ports A, B and Events enabled, but you wish to disable MIDI port B
for one Cue only.

Press MIDI port B Enable switc h two times in quick succession, (rather li ke “double
clicking” with the mouse). The LED in the MIDI port B Enable switch will now “flash”.

Recall the required Cue. MIDI information from port A and the Events will be tr ans­mitted, but no data will be transmitted from MIDI port B. The LED in the MIDI port B
Enable switch will now return to fully “on”. If another Cue is now recalled, then data
will be transmitted on MIDI ports A, B and the Events.

The MIDI Program Change filter can be selected on or off.

Alternatively, when th e MIDI Program Change filter is “off”,

The reason for including this option, is that some types of MIDI controlled equipment

If motorized VCA channel faders are used in conjunction with motoriz ed DC master
faders, then the system can be configured so that a single DC master fader can
move all the channel faders in the console. More specifically, if a group of faders con­trolling the orchestra “mix” are assigned to a particular DC master fader then logi­cally, they will all move relative to the master controlling element. In this situation
“A UX fro m VC A” do es not h a v e the sam e me an in g as a no n- mo tor f ad er s yste m. Th e
mode of operation where the c hannel faders “move ” relative to the DC master faders
is called Group-Link mode.

In many live sound applications, a motor fa der system needs to have a second mo de
of operation in order to mak e the system as flexible as poss ible . When Group-Link is
off, channel fader movements are “disconnected” f rom the DC master fader move­ments , although level changes are still achieved using VCA control. This allows the
motor fader system to behave more like a manual fader system.

*URXS0/LQN#RII

The channel fader motor system is “disconnec ted” from the DC master bus motor
system. In this mode, DC master faders

will not

“move” channel faders.

When AUX VCA

ter fader will control the

Main

VCA and the

Aux

VCA on the channel .

■■■■

The main and the auxiliary signal levels will follo w the master control el ement.

In this mode, the motor f ader system w ill behave in th e same way as a non-motor
fader VCA system, except that chann el and DC master faders may be pr ogrammed
for “snapshot” position changes even if the appropriate m aster is at ∞.

The 7496 Dual I nput Chan nel is one of two fully programmable mono input channels
where al l s wi tch dat a and po tent i ome te r po si ti on ca n be sa v e d t o a nd re ca ll ed fro m a
cue, using the CADAC Sound Aut omation Manager software.

The inputs have contr ols for gain, 20dB pad, phase change, phantom power, on/of f
and PFL. This allows either input to be used with microphone or line level sources.
The two input signals are “mixed” when both input amplifiers are selected on. The
Oscill ato r Bus c an be i nj ecte d i nt o bo t h i nput a mpl i fier s an d all i np ut switch in g can be
isolated from the computer.

The dir ec t out p ut ma y be se le cted pr e o r po st the c ha nn el fa de r, an/o r pr e or pos t the
EQ section.

Routing switches to all 16 sub groups are provided and the pan-pot may be inserted
to “pan” between any combination of “odd” and “even” sub groups.

There are ten mono and one stereo auxiliary send sectio ns. Each of the aux-sends
can be switched on/off and pre or post fader or pre EQ.

The four-band equalizer has controls for ±18dB boost or cut, variable fr equency and
“Q”. The equalizer section is independent from the variable frequency for low pass
and hi gh-pass filter sections. It is therefore possible to progra m the channe l so that
when input 1 is selected, the four b and EQ is inserted and when input 2 is selected,
the LP and HP filters are inserted.

An external audio processi ng device can be conn ected to the module via 2TRS”
send and return jacks. The external processor is connec ted in series with the chan­nel signal when “Insert” is selected. The EQ and Filter s can be switched pre or post
the insert point.

All audio inputs and output s are electronically balanced.

The 7830 Dual I nput Chan nel is one of two fully programmable mono input channels
where all switch data and potentiometer position data can be saved to and recalled
from a cue, using the CADAC

Sound Automation Manager

software.

The inputs have contr ols for gain, 20 dB pad, phase-change, phantom power, on/off
and PFL. This allows either input to be used with microphone or line level sources.
The two input signals are ‘mixed’, when both input amplifiers are selected ‘on’. The
Oscill ato r Bus c an be i nj ecte d i nt o bo t h i nput a mpl i fier s an d all i np ut switch in g can be
isolated from the computer.

The direct outpu t may be selected pre or post the channel fader , and/or pre or post
the EQ section.

Routing switches to all 16 sub groups are provided and the pan-pot may be inserted
to ‘pan’ between ‘odd’ and ‘even’ sub groups.

There are ten mono and one stereo auxiliary send sectio ns. Each of the aux-sends
can be switched on/off and pre or post fade r.

The four-band equalizer has controls for ±18 dB boost or cut, variable frequency and
“Q”. The equalizer section is independent from the variable frequency low-pass and
high-pass filter sect ions. It is ther efore possible to program the channel so that when
input 1 is selected, t he four band EQ is inserted and when input 2 is sele cted, the LP
and HP filters are inserted.

An ext ernal aud io proce ss in g device can be conn ec ted t o th e mod ul e via ‘T RS ’ se nd

All Matrix Groups have a “SEND” and “RETURN”

break-jack

facility. This is to allow
the group signal to be sent out to, and returned from an external audio-processing
unit. The group signal is always present at the “SEND” jack, but when ‘insert’ is not
selected, the group signal will by-pass the “RETURN” jack.

Press the “INS” button to ‘open’ the “RETURN” jack and receive the modified signal
from the external audio-processing unit.

This function ‘isolates’ the switch and potentiometer recall data (for Matrix A and B)
from the computer. There are many instances during a production rehearsal, when
modul e routing or lev el change s need to be made to solve a problem. When you ar e
rehearsing a sequence of cues, there may not be time to record the changes in all of
the cues that are affected. When you press t he ‘ISOLATE’ button, previousl y
recorded switch and pot data will be ignored by the module, leaving t he controls at
their new setting until you cancel the function.
