Do not place heavy objects on the control surface, expose it to s harp objects or handle the console in any way that may cause damage e.g. rough handling and/or excessive vibration.

Do not subject the equipment to dirt, dus t, heat or vibration during oper ation or stor age. Never expose the console to rain or moisture in any form. Should the console become wet, turn it off and disconnect from mains without further delay. The console should be given suff icient time to dry out, before recommenc ing operation.

When cleaning the cons ole, never use chemicals, abra sive substances or sol vents. The console control panels should be cleaned using a soft brush and a dry lint-free cloth. For pe rsistent ma rk s, us e a sof t clo t h and is op r opyl alc oh ol. Switches and potentiometers do NOT require cleaning or lubrication. For faders, see below.

Transport the cons ole in its purpose built flight-case; whilst at the sa me time taking precautions to protect the co ntrol surf ace from any damage. Alway s make sure adequate manpower is available and correct lifting methods are taken when moving the console.

Read the following before using the equipment

Keep these instructions for future reference. Follow all warnings in this manual and those printed on the power supply units.

The console must be installed following the guide lines in this manual. Never connect power amplifier outputs directly to the console. Connectors and plugs must never be used for any other purpose than for what they are intended.

Never use the power supply units without covers fitted. All service work must be carried out by qualified personnel only.

The power supply units must always be connected to correctly r ated mains p ower as referred to in this manual and marked on the power supply units. The power supply units must, at all times, be connected to the local mains power supply using the supplied po w er c or d. In c ase s w her e th e supp l ie d p lu g d oes not fi t , a qu al if i ed elec tr ic ia n must be consulted.

The power cord must be routed in such a way that the risks of accidentally stepping on it, stretching it or it being pinched, are minimized.

THIS EQUIPMENT MUST BE EARTHED !

In order to minimize risks of fire hazards and/or electric shock , the power supply unit must ne v er be e x pos ed to moi st ur e or wa te r in any f orm; or b e us ed i n a damp or w et environment. Never place liquid c ontainers, such as for instance coffee/t ea mugs, on the power supply uni t, so as to avoid spillage into openings.

Ventilation slots on the power supply or the console must never be covered or in any other way obstructed. Air flow required for safe operation may otherwise be restricted. Where the console is to be operated in its flight-case, then this must be located in such a way that it allows for proper ventilation.

The C-Type features CADAC’s unique frame design which allow use rs 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 C-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 position in the console frame, by means of top quality two-part connector system, which is designed as a m ating pair to provide excellent mechanical and electrical reliability.

A rail system is used to guide each mod ule into its correct po sition. Also, the console design allows modules to be removed or inserted without powering down.

Cadac consoles are designed to al low the use of two independent power supplies in a redundant configu ration – “main” and “backup”. Both power supply units are used to power the consol e system so that under normal conditi ons, the ‘load’ is shared between the “main” and “backup” PSU’s. If a fault occurs in one of the power units (cau sing it to ‘shut-down’), the remaining power unit will power the console.

In situations where it is necessary to provide a separa te ‘feed’ to each PSU, 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.

FIG 1-2. AC mains grounding diagram (single phase 208-240V)

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 ‘EAR TH’ conductor is connected on all PSUs

the a.c. supply has an ‘EARTH’ conduc tor that has a

and

continuous circuit to the “zero-signal reference potential” point in the building. The ZSRP po in t i n a b u ildi n g i s u sua ll y f o un d n ea r th e p la ce whe r e the a. c. ‘m ain s’ s up pl y enters the building (often referred to as the “MAIN GROUND REFERENCE EARTH ELECTRODE SYSTEM”).

The g rounding schem e 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 metalwork of the power supply u nits. In o rder to take full advantage of the “RF noise immunity” capability of the CADAC system, PSU a.c. mains cables and the a.c. mains supply EARTH conductor must be conn ected correctly.

CADAC power supply units are designed to run from a minimum of 208V, 50/60Hz a.c. In many parts of the world where the single phase a.c. supply is 110/120V, the CADAC power supplies are adjusted to operate at this input voltage.

The C- type input channel module is featured with microphone and line level inputs, controlled via a stepped gain control calibrated in dB. A three band equalizer with a HP-filter is provi ded as well as four mono auxiliary sends and a stereo fo ldback. Routing can be perf ormed to 16 groups a nd the module features a separate stereo mix. The direct output is controlled via a dedicated level control. An LED meter with a measuring range of 57 dB is positioned beside the channel fader and indicates the pre-fade r/direct ou tpu t si gnal level.

Output from the internal sine wave oscillator/Pink Noise Generator.

TB O/P1 & O/P2 are balanced line level outputs from the desk talkback system.

IMPORTANT NOTE: Pin 1 on XLR connectors and the ‘sleeve’ connections on the jack sockets are connected to the FRAME. This is to ensure that the console can comply with the Electric Compatibility (EMC) directive.

On the 1st January 1996, new European legislation known as the EMC Directive came into force. The EMC D irective requires that all electronic e quipment 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 systems or sub-systems. Similarly, the product must also be immune to a wide range of natural and man-made electromagnetic inte rference 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:

All cable ‘screen’ connections are bonded to the frame.

The figure below shows the required connection sc heme for XLR connectors.

Please note that in the case of ‘line’ or ‘free’ connectors (XLRs on cables), the 'pigtail ' formed from the cable screening braid should be as short as practical and soldered to the halfway between the The twisted pair should be left 'twisted' right up to the signal solder tags.

The cha s sis half of th e connector is bonded to the metalwork with the usual nuts, bolts and spiky washers. The solder tag should be as l ong as possible so that the length of the 'short wire' is a minimum. The twisted pair (from the signal pins - pin 2 & pin 3) are soldered onto the motherbo ard adjacent to the 'input RFI filt er' components.
