Introduction v

,QWURGXFWL RQ
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.
415 7KH#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 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
■■■■
the cable shield connects directly to the PSU unit chassis.
Connect the cable shield to the metal panel where the remote s tart switch(es)
■■■■
are mounted.

If replacing a power supply unit is required, please note the following:
The work should only be carried out by a suitably qualified electrician.
■■■■
Make sure that the po wer supply system’s power switches are in the OFF posi-
■■■■
tion and the unit is disconnected from t he mains.
Observe the correct polarity when connecting the new PSU.
■■■■
Note that a console must never have one voltage with out the other, for example
■■■■
+18V must never be fed into the console without -18V.
When switching the power supply 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 o f the O N pu sh -b ut ton imm edi a tely. Failure to do so ma y le ad to fi re h aza rd and major damage to the console.

The S- Type mono in pu t cha nn el mo dule f e atu r es a microp ho ne inpu t amp lif ie r, which 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.
