Outline C.D.H 483 HI -PACKS

C.D.H. 483 HI-PACKS The C.D.H. 483 Hi-Pack is the Butterfly system’s element for mid-low, mid and high frequency reproduction. Weighing just 35 kg. the cabinet has an unmistakable shape (the only one among current line array systems covered by an international patent) which brings to mind the butterfly from which it takes its name, thanks to the triangular opening in the upper and lower “sides”. This original design solution favours the optimum coupling of array elements up to the highest frequencies, keeping the distance between the sources as short as possible and at the same time providing them with a continuous loading ‘baffle’. Unlike other units, Butterfly’s shape doesn’t contrast with the cabinet’s technical operation, so doesn’t accentuate any diffraction or alteration of mid/high response. HF SECTION The high frequency section of the Butterfly system is equipped with a 3” (1.41” throat) compression driver coupled with a D.P.R.W.G. (Double Parabolic Reflective Wave Guide) device, another Outline invention for which an international patent has been applied for. The result of three years of research and tests, the D.P.R.W.G. is a really original device and is geometrically based entirely on precise mathematic calculations. It has the job of taking a circular planar (flat) wavefront emitted by the source at its input (e.g. that of a compression driver) and transforming it into a rectangular planar wavefront at its output, keeping signal paths identical from every emission point of the source. The rectangular planar wavefront thus obtained can be loaded by an appropriate horn or waveguide to ensure the necessary coverage.

As well as a 3” compression driver, it’s equipped with four high-efficiency 8” mid woofers: two band-pass loaded (110-400Hz) and two reflex high-pass (110-1250Hz) loaded by the sides of a waveguide with a 90° dispersion angle. These two sections are connected in parallel without any type of passive crossover, so can both be powered using one amplifier. By means of the appropriate upper mechanical filter of the first band-pass section, obtained with the precise restricting design of the resonance chambers and the respective tuning, emission phase has been shifted, enabling the energy in the portion of band reproduced by both sections together to be doubled. This peculiarity, at present an exclusive feature, enables to make up for the lack of power in the mid/low frequencies typical of other line array elements whose compact dimensions are comparable to those of Butterfly C.D.H. 483 High-Packs.
