J-Type

  • Overview


    The Cadac J-Type has a uniquely enviable reputation when it comes to delivering faultless performances night after night, year after year, on almost every imaginable type of production. It has proved itself in critical applications where quality is paramount.  The J-Type signifies top quality audio all within a rugged, reliable package. 

    Where flexibility is essential the J-Type can be configured to suit the application in hand, without compromise, and equally importantly, to combine this with intuitive operation during a performance. The J-Type’s superlative audio is also matched by exceptional reliability in the often hostile conditions that are typical of live sound environment.


    There is an impressive range of input modules to choose from for the J-Type, underlining its performance capabilities. Users can combine the original mono inputs with the programmable dual input and stereo input channels to get the precise routing and mix required for every cue. This is complemented by the J-Type’s versatile matrix - with up to 16 sub and 32 matrix group outputs.

    The J-Type was the first console to feature Cadac’s unique frame design, which allows 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. For audio quality, the J-Type maintains the Cadac tradition for exceptional performance.

    All of the inputs, insertion send/returns and outputs are electronically balanced, as are all audio mixing busses.  The J-Type Live Production console epitomises Cadac’s innovative design approach.

    Features


    Frame

    The J-Type is constructed from extruded aluminium bearers, fixed to 7mm two-part aluminium end profiles. This allows multiple frames to be positioned so that modules are almost adjacent. Internal audio bussing is balanced and uses ribbon cables, with ‘floating’ connectors fitted on to 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 lamp connections, as well as optional bus expansion connectors. The frames incorporate multiple cooling fans with a 5- speed control. Any frame size may be specified from 25 to 63 modules wide.


    Module
    The J-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 may be plugged into any position in the console frame, by means of a 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 guide each module into its correct position. The console design allows modules to be removed or inserted without powering down.


    Connectors
    Audio connections will be determined by the user’s specification and whether a patch bay is required. XLR type connectors are standard for all inputs and outputs. 1⁄4" jack sockets are used for insert sends and returns. Two other possible variations are:

    Military standard round multi way connectors for a touring system, with a separate patch bay.

    Varelco multi way connectors for a fixed installation, with a separate patch bay.


    Automation
    The J-Type provides a sophisticated level of automation when supplemented by Cadac’s Sound Automation Manager for Windows®, in conjunction with the programmable modules. The console’s Central Control Module interfaces to a standard PC, with the Sound Automation Manager handling cue management, routing and VCA automation - supported by comprehensive visual feedback of all routing and variable functions, including fader positions. For additional flexibility, all console programming for a production can be implemented off-line, porting to the on-line console PC via the Ethernet LAN.


    Power Supply
    Each J-Type console requires the following:
    - ±18v for the audio electronics
    - +13v for LEDs, relays and logic circuits
    - +48v for phantom powering of microphones
    The power supplies are suitable for rack-mounting or flight cases, and are connected via a heavy duty, shielded multicore cable with military circular bayonet connectors at each end. Each console may be powered by two independent power supply systems, operating simultaneously.


    Finish
    All Cadac J-type front panels are machined from custom-designed 3mm aluminium extrusion, which is stove enamelled, silk-screened and lacquered. The silk-screened legend is designed to withstand arduous operating conditions. Custom-made flight cases are available for the J-Type console, as required.
