Welcome to the CADAC S-Type compact frame mixing console. The S-Type is the
result of extens ive market research, reflecting us ers’ need for a high quality, mode rately sized console with state of the art design and perfo rmance.
CADAC have been synonymous with superior audio quality, adaptability in use and
roc k solid build for over three decades. The S-Type, created from the same lineage,
is equally suitable for the hard life on the road as well as the perhaps more peaceful
existence in an industrial, corporate or theatre setting.
As is the case with the rest of the CADAC line-up, the S-Type provides complete flexibility that allows for any configuration the user wishes to apply, whilst providing the
reliability that is paramount to t he production of a show, concert or corpor ate event.
The audio legacy of pre vious CADA C mixing consoles is ref lected in the design of
the new S-Type. For those of you familiar with the legendary J and F-Types, it will
come as no surprise to find the same renowned mic amplifier , VCA and fully parametric 4-band equaliser and respected audio architecture. The S-Type mirrors the
same attention to quality and detail that have made the CADAC name the ultimate
choice for the discerning pr ofessional.
Ergonomics has been placed high on the design brief. Every function switch is supported by an indicator LED for full visual feedback in low light conditions.
All internal busses are fully balanced and use very low value mix resistors to provide
both low noise and exceptionally low crosstalk.
Output sections are fully bala nced and compensated* to provide low noise with the
power to drive long lines - again with very good CMRR.
(*Compensated means that if one leg of the balanced circuit goes short circuit, there
will be no 6dB drop in level.)
All ar eas of circuitry are extensively power decoupled. This prevents broadband
noise from being transmitted into adjacent circuits through the pow er rails. Extensive
decoupling of the signal paths minimizes the low frequencies phase shift.
The S-Type frame is available in 3 sizes - 17, 25 or 33-way. In combination, these
frame sizes cater for the most common console requirements, and may, of course be
configured to meet your sp ecific needs. A standar d feature is the ability to c onnect
frames together via the external frame bus connector.
Fina lly, it goes without say ing, that in the CADAC tradition the sound quality of the SType is in a class of its own.

Mixing consoles comprise of a number of input channels and output groups with
associated faders, monitoring and control functions. When module positions are
fixed in relation to the frame structure, various operational compromises may occur.
The S-Type console system al lows for any module to be plac ed into any frame position and to change the number of frames associated with the system to increase or
decr ease the number of input channels and output gr oups to meet the needs of a
particular project. Please be aware that the console needs to be turned off before
any reconfiguration can be carried out.
There are three S-Type frames offering either 17, 25 or 33 module positions (slots).
Each frame has provi s ion for main and backup power suppl y inputs and any two
adjacent frames have full audio bus and control function interconnection via 3 x 37way D-type connectors for multiple frame connectivity.
The S-Type frame provides a total of 20 ba lanced busses - 8 sub-group bu s ses, 1
dedicated stereo bus, 6 mono busses, 2 stereo auxiliary busses, 8 matrix busses
and PFL. A further 8 matrix send busses and a stereo listen bus are provided.
Standard channel VCA faders can access up to 8 VCA master faders.
The S-Type is designed to comply with following standards: EN55103-1:1997,
EN55103-2:1997, EN60065:1998.
4157KH#IUDPH
The S-Type frame is constructed from 1.6mm Zintec , fixed to 4mm aluminium end
profiles. This constructi on allo ws multiple frames to be positioned so that modules
are almost adjacent. Internal au dio bussing is balanced and uses ribbon cables.
The rear panel of the frame contains outputs for the stereo master, plus insert send s
and returns for the same. Two PSU input connectors are prov ided - one for ma in and
fo r the backup supply. Power rail LEDs are provided for each PSU input. The S -Type
frame also incorporates two Littlite connectors in addition to fan and Littlite fuses. A
headphone jack is provided on the front of the frame.
The three standard frame sizes enable a vast variety of configurations to be
achieved. For example:
17 slot frame: 8 mono input channels, 8 output g roups and 1 stereo master
25 slot frame: 16 mono in put channels, 8 output groups and 1 stere o master
33 slot frame: 24 mono in put channels, 8 output groups and 1 stere o master
Note: The choice is yours, a 33 slot frame could be configured as follows:
20 mono input channels, 8 stereo input channels, 4 output groups and 1 stereo master.
By bu s linking multiple frames together, larger co nfigurations can be achieved. For
example:
Two 25 slot frames:
40 mono input modules, 1 stereo input module, 8 output groups and 1 stereo master.
One 25 slot fr ame and one 33 slot frame:
48 mono input modules, 1 stereo input module, 8 output groups and 1 stereo master.
Three 25 slot frames:
56 mono input modules, 10 stereo input modules, 8 output groups and 1 stereo master.
The module electronics are cooled via internally mounted silent fans.

The main power supply for the S-Type is integrated into an external 2U rack mount
unit with the option of a backup PSU. See sub-section 2.3.1 Power sup ply descrip-
Mono and stereo input modules are available for the S-Type. Both modules provide
balanced insert sends and returns; four band parametric EQ - selectable pre or post
insert and high-pass filter; balanced direct output - selectable pre/post fader, or post
MIC pre-amplifier,
Each module incorporates a VCA channel fader, VCA Master assignment swit ches
and a full range level meter (with dual input meters on the stereo input module).
Full details of the module functions can be found in chapters 4 Mono input module
8411 and 5 Stereo input module 8412. Also, see Appendices .
Each of t he outp ut mod ul es pr o vi de one Su b-G ro up outp ut , an 8-w ay level co nt rol l ed
send to Matrix, Matrix Master, and an Auxiliary Master output.
Up to 8 modules may be specified per cons ole (maximum configuration b eing two
8413 and six 8415 modules) and each module can be placed anywhere in the multiframe console structure (they do not need to be placed adjacent to each other, or
even in the same frame). Visual monit o ring of output levels is p rovided on full range
LED- meters, PFL facilitie s on the outputs are provided, as are balanced insert points
on the Sub-Group and Matrix outputs.
Full details of the module function can be fo und in chapter 6 G roup, Matr ix and Auxiliary Ma s t er mo dules, 8413 stereo and 84 15 mono.
The Stereo Master module is fitted with a 100mm Penny & Giles fader, balanced
insert send and returns and balanced outputs (these are fou nd on the rear of the
frame). The Stereo Master module also provides metering for both the main stereo
mix and listen busses, while the stereo mix bus can also be rout ed to the Matrix
sends in true stereo or summe d mono via 4 dual concentric potentiometers.
Provision is made to inject an unbalanced stereo input source into the main stereo
bus.
The S-Type console offers the operator PFL monitoring functionality. If the source
signal is mono it will appear in mono a nd if the signal is in stereo it will appear in stereo.
PFL appears at the Listen output, which provides stereo meters, level control via a
potentiometer and mute control. The Listen output busses appear on balanced
XLR's on the re ar of the module. PFL is also routed to the Headphones level control
and mute, the output of which is provid ed via a jack socket on the front of the frame
and is capable of driving 8 ohm loads.
The module also incorporates an oscillator with selectable frequencies at 100Hz,
1kHz and 10kHz. This is then routed via a level control to either the channels or the
groups.

The S-Typ e console is suppl ied with the model 8500 Power Supply Unit. Each 2U x
19” rack mount power unit supplies all 4 voltage required by the S-type console. If
more than one frame is to be used, then the 8400 Power Supply Unit may be used.
Cadac consoles are designed to allow th e use of two in dependent pow er supply systems in a redundant conf iguration - main and back-up. Both power supply units are
used to power the console system, so that under normal c onditions, the load is
shar ed equal ly between the main and back-up PSU. If a fault occurs in one of the
power units (causing it to shut down), the remaining power unit will power the console.
Designate one power supply unit as “PSU 1” and the other as “PSU 2”. PSU 1 and
PSU 2 sh ould be connected to the same phase on the same ‘spur’, wherever possible . In situations where it is necessary to provide a separate “feed” t o each PSU system, m ake sure the cable lengths are the same. This is to minimize any induced AC
power input noise by ensuring that the ‘EARTH IMPEDANCE’ is the same for both
PSU-systems.
1#/
The AC input connectors on each po wer supply have three conductors: LIVE
(brown), NEUTRAL (blue) and EARTH (green/yellow). For safety and electromagnetic compatibility considerations, it is essential tha t the EARTH conductor i s connected on all PSUs and the AC 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 AC mains supply enters the
building (often referred to as the MAIN GROUND REFERENCE EARTH ELECTRODE SYSTEM). The basic concept for correct AC mains wiring distribution is
shown in figure 2-2. If yo u 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 g rounding scheme in CADAC consoles is designed to meet the rigorous EEC
Elec tromagnetic Compatibility require m ents (EMC directive - 1996). Any RF noise
induced in the console f rame(s) is directed to the loca l ZSRP, which is the metalwork
of the power supply units. In order to take full advantage ‘RF no ise immunity’ capability of the CADAC system, PSU AC mains ca bles and the AC mains supply EARTH
conductor must be connected correctly .

CADAC 8500 power supply units are desi gned to run from a minimum of 100V u p to
a maximum 250V, 50/60Hz.
The 85 00 is rated at +13V@15A, ±18V@11A and 48V@0.5A. Th is is sufficient to
supply power to one frame. In the case of more than frame, each frame can be powered b y a p ai r of 85 00 P o w er Sup pl y Uni t s (on e ma i n an d one f o r ba c k- up pu rpos es ).
Alternatively, 8400 Power Supply Units may be used, however please contact your
local distributor, or CADAC directly before any connections are made.
The AC input is connected to the PSU via a 3-core cable, CMA reference 3183TQ BASEC approved.
51616;833#6ZLWFK0PRGH#SRZHU#VXSSO\#XQLW
The 8500 is based on a Excelsys power block, rated at +13V@15A, ±18V@11A and
+48V@0.5A, with additional circuitry as shown in the accompanying draw ing set.
The 2U power supplies are suit able for rack-mounting or flight cases, and are connected via a shielded multi-core cable with 6 pole m ilitary circular bayonet at each
end. Each console may be powe red fro m two independen t powe r supply systems,
operating simultaneously for continuous redundant operation.

Each 8500 switc h-mode power supply provides the f ollowing ou tputs: 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 fitte d with the remote start switches if required.
Fig 2-5 shows the circuit for starting up a ‘syst em’ 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 pr ovide a single switch for all PSUs if req u ired. If multipl e switches are to be used, see fig 2-4.
NOTE:
The remote start switch must be of a ‘momentary’ type . Y ou can use 3 separate
■■■■
single pole switches for each power supply to turn on 13V, ±18V and 48V outputs of
the PSUs 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

is indicated by the associated LED illuminating. Press the PAN button if you want to
use t he PAN control. The signal can also be routed to the dedicated stereo bus using
the associated ster eo push-button (ST) and PAN control, the latter being permanently active on the stereo send.
The input channel module has a dedicated Auxiliary ON/OFF switch for each Auxiliary send. The module has facilities for routing to 8 auxiliary busses. The first of
these are stereo and ar e controlled by dual concentric potentiometers, the upper for
setting the signal level, and the lower control for positioning the signal in t he stereo
fiel d.
The remaining six sends are mono and have associated sign al level controls.
All eight auxiliary sends can be individually switched pre or post fader.
By using the assignment buttons in the Sub-Group section in the respective input
module, select a Sub -Group to w hich the signal has been routed. On the appropriate
matrix sends section on the Group/Matrix module (8413 & 8415), enable the desired
matrix send by selecting its corresponding switch. The matrix level can then be set
using the associated matrix output l evel control.
To route the signal from the stereo mix bus to the matrix, se lect and enable the
appropriate matrix send switches on the stereo output module (8414).
Example:

is the same as that fitted to the legendary J-Type - the most prevalent theatre console in the industry. The module has a full four-band parametric equaliser - also originating from the J-Type - which may be switched to pre or post the insert point. T he
8411 also includes a HP-filter with a cut-off frequency of 160Hz and a slope of 12dB
per octave.
The module incorporates a fully balanced direct output with level control; normally
post fader but may be switched to pre fader or even post mic amplifier.
The in put module allows rout ing to eight sub groups with optional pan control. It can
also route to a dedicated stereo bus via the pan control. Additionally, it is possible to
route to eight auxiliary busses; the f irst tw o of which are stereo on dual concentric
potentiometers - level on the upper control and PAN on the lower control. The
remaining six are mono with level control. All eight sends can be enabled and
selected to be sourced pre or post fade r on an individual basis.
Each input channel can be assigned to up to a maximum of eight VCA masters.
The 84 11 input channel module is equipped with a fully balanced insert send and
return - the send stays live irrespec tive of whether the in sert button is pressed. Also
included are PFL and Mut e buttons - incl usive of a destru ctive solo function.
The module is fitted with a 100mm P&G fader and located next to it, a 12 segment
prefade input mete r with a range of +18dB to -36dB (meter source is pre-fad er).
There is also a fader-open LED which, when extinguished, indicates that either the
channel fa der is closed or muted, or an assigned VCA Master is m uted or pulled
down to infinity.

The S-Type stereo input module has line level inputs for left and right channel
respectively. In addition, it features a full four-band para metric equaliser which c an
be switched to pre or post the insert point. An HP-filter with a cut-off frequency of
160Hz; slope 12 dB per octave is included.
The stereo input module incorporates a fully balanced direct output with level control;
normally post fader, but may be switched to pre fader, or even post input.
The module allows routing to eight sub-groups in true stereo with optional pan control. It can also route to a dedicated st ereo bus via the pan control. Additionally, it is
possible to route to eight Auxiliary busses; the first two of which are stereo on dual
concentric potenti ometers - level on t he upper control and pan on the lower control.
The remaining six are mono sends with level control. All eight sends can be enabled
and sel ected to be sourced pre or post fader on an individual basis.
Each stereo input channel can be assigned to up to eight VCA masters.
The 84 12 stereo input module is equipped with a fully b alanced insert send and
return - the send stays live irrespective of whether the insert button is pressed. Also,
included on the module are PFL and Mute buttons - inclusive of a destructive solo
function.
The module is fitted with a 100mm P&G fader, and located next to it, a 12-segment
meter with a range of +18dB to -36dB (meter source is pre fader). There is also a
fader-open LED, which, when extinguished, indicates that either the channel fader is
closed or muted, or an assigned VCA Master is muted or pulled down to infinity.
Following pages describes the 8412 module in detail.

The 84 14 module contai ns the main stereo output with a full size 100mm fader, 12segment meters for left and right channels in addition to PFL, Mute and Insert.
The module enables you to send the stereo mix to the matrix outputs via individual

control), even number goes to right (lower control). In addition, each pair of sends
has a sum-to-mono feature.
The oscillat or can be switched to 100Hz, 1kH z and 10kHz and can be routed to the
channels and/or the sub-groups.
The talkback section contains the same mic amplifier as found on the mono input
channels with optional 48V and HPF. The talkback signal can then be routed to the
auxil iary sends and sub-groups.
The listen output level is controlled via a dedicated level control. Two dedicated 12segment level met ers provide vi sual feedback. Mute, Hold and Clear butto ns are
included.
In normal mode, the PFLs are self cancelling, i.e. pressing any PFL buttons on the
console will clear any previous selection. By selecting the PFL Hold switch it is possible to enable multiple PFL switches simulataneously .
A temporary hold function can be achieved by selecting and holding the desired PFL
switch, while adding additional PFLs as required. Pressing the PFL switch a second
time will clear the selected channels and resume normal operation.

In live sound applications, it is normal f or the console to be situa ted a long way from
its sound sources and ampl ifier/loudspeaker sy stem. This inevitably means cable
runs of m an y h un dre ds of me tre s . I n or de r t o mi nimi z e n oi se an d int e rf e ren ce pi c k u p
on the c ables, it is generally agreed that the “balanced lin e” connection system is
essent ial. On the S-Type console, all inputs and outputs (including insert points ) are
full y balanced. The only exception to this is the external input on the ste reo master,
which is unbalanced.
Great att en tio n i s pa i d t o the co nst ruct i on an d la y o ut of all pr in te d cir c ui t b oa rds u se d
in the console. It is relatively simple to design high performance circuits that work
perfectly on the bench, but it is somewhat more difficult (and costly) to engineer the
printed circuit boards in a way t hat allows this performance to be re peated in produc tion . CADAC use layout techniques that have been developed ove r the years to minimize variations in production quality and in the case of logic circuits, to absorb any
interference that may be generated inside the console.
APP-I
The part of a console that is mo s t pr on e to interferenc e pick u p is the mi xi ng bus.
Mixing bus wires have dimension s large enough to allow them to be one quarter of a
wav e - leng t h of ma n y me di um w a v e rad io t ran smi ss ions . In ot her wor d s , a mix in g b u s
can be an antenna for radio reception. Since the airwaves are becoming ever more
pollu ted with radio t ransmissions, CADAC use a balanced bus s ystem for all mixing
requirements.
In gen eral, analog audio circuits do not tr ansmit unwanted signals into the surrounding air space (unless a poor design or component fault causes a circuit to pr oduce
oscil la tio n) . O n th e o t he r ha nd , u si ng a com pute r (em be dde d proc es sor or co nt rol l er )
to handle any form of automation always produces a wide range of unwanted high
frequency radiation. Some artifacts from this
system
neered to min imize any pote ntial interference generated inside th e system and to
pre vent radiation into the environment. The techniques used also have the adva ntage of making the system immune to external interference.
On the 1st January 1996, new European legislation known as the EMC Directive
came into force. The EMC Directive requires that all el ectronic equipment manufactured or i mpo rted f o r sal e in th e EEC m ust no t e mit el ec tro ma gne t ic inte rf e r en ce tha t
can impair the performance of other sys tems or sub-systems. Similarly, the product
must also be immune to a wide range of natural and man- made electromagnetic
inte rfer ence in its operating environment. Many countries outside the EEC are also
developing or have already put into place similar legislation. In order to conform to
these rules, a number of changes were required to the basic design of our consoles
and modules. One of the main changes is:

Balanced lineA balanced line consists of two identical conduc-

lines are very useful in reducing or eliminating
unwanted interference. Interference induced in
each conductor signals have the same polarity
in both lines and the noise currents flow in the
same dire ct io n. A t the lo ad en d of t he li ne, no is e
currents are found to be opposite in polarity, but
equal in amplitude, so in theory, they cancel
