    Using Sound Projects Array Calculator (SPArC™) To determine the optimum angle settings of the array elements, array position, expected SPL levels and other array configuration parameters SOUND PROJECTS has developed SPArC™; a pragmatic array calculation tool. Based on the venue parameters SPArC™ instantly calculates the most favourable line-array configuration and processor pre-set.

    General guidelines SOUND PROJECTS has configured several controller presets to cover any venue situation. These settings will deliver the most accurate frequency response at the audience areas. It is advised to use no or only minor EQ adjustments afterwards. One must be very precautious because, due to venue acoustics, the frequency response may differ remarkably between places.

    SOUND PROJECTS has prepared a tenfold controller settings, which are available as presets for several recommended controllers available in the market today. The correct controller preset number can be selected with table 3.3. In addition SPArC™ can be consulted for the proper preset number.

    IEC 268-5 Power), only the latter two are real standards and therefore comparable. The other ways of specifying are more fanciful and therefore not serious. Sound Projects transducer power ratings are calculated based on minimum impedance (Z-min) and the RMS voltage of the relevant band-passed noise input signal.

    Threshold value and amplifier gain factor When you use the amplifiers supplied by Sound Projects they have a gain of 32 dBu. The gain factor of an amplifier is extremely important for the threshold value of the limiter! In table 2.6, the limiter parameters are listed in case of amplifiers with a gain of 32 dBu.

    The Sasy-rig™ flying system has been designed to set up acoustic vertical line-arrays in an easy, fast and flexible way. All the necessary cabinet rigging hardware is stored within the SP20-Linex housing. In general, the only additional requirements include an Sasy-rig™ fly-frame and tilt- bar, motor hoists, transport flight cases and qualified rigging personnel.

    6.2 SP20-LINEX enclosure with integrated flying hardware Flying Frame The Sasy-rig™ flying frame is designed to fly up to 24 SP20-LINEX enclosures in a ‘dead-hang‘ set-up. SPArC™, specially designed line-array software, automatically calculates the corresponding maximum number of cabinets for each situation submitted in the program and signals when weight load limits are exceeded.

    Store the enclosures in clusters of three in a flight-case and mark each flight-case with L for the left array and R for the right array plus the number of the cabinets in line. The SP20-LINEX transport flight case has truck-pack dimensions. Two flight cases (1.20m width) will tightly fit inside most trailers.

Lift the fly-frame at the lifting-point together with the first 3 cabinets out of the flight-case.
