C.D.H. 483 Hi -Pack是Butterfly系统用于中低频、中频和高频重放的元件。重量仅34 kg。由于上、下两侧都有三角形开口，箱体具有明显的蝴蝶形状，从而获取其名称。这种原始设计的解决方案有利于阵列元件最佳耦合到最高频率，保持声源之间的距离尽可能短，同时为它们提供连续的负载“挡板”。

Butterfly系统的高频单元使用3寸（1.41寸喉口）的压缩驱动器，完全基于精确数学计算几何，与D.P.R.W.G.（双抛物线反射波导管）耦合，以获取声源在其输入端（例如压缩驱动器的输入端）发射的圆形平面（平坦）波前，并在其输出端将其转换成矩形平面波前，保持信号路径与声源的每个发射点相同。由此获得的矩形平面波前可以由适当的号角或波导管负载，以确保必要的覆盖范围。

4个高效率的8寸中低音单元：2个带通负载（110 - 400 Hz）和2个反射高通（110 - 1250 Hz），由具有90° 扩散角度的波导管侧面负载，并联连接，没有任何类型的无源分频，因此两者都可以使用一个功放驱动。

The C.D.H. 483 Hi-Pack is the Butterfly system’s element for mid-low, mid and high frequency reproduction. Weighing just 34 kg. the cabinet has an unmistakable shape 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’.

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 geometrically based entirely on precise mathematic calculations to take 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.

Four high-efficiency 8” mid woofers: two band-pass loaded (110 – 400 Hz) and two reflex high-pass (110 – 1250 Hz) loaded by the sides of a waveguide with a 90° dispersion angle are connected in parallel without any type of passive crossover, so can both be powered using one amplifier.
