A Line Array that works like a real point source.
Variable Acoustic Lens Technology VALTEC™ makes it possible.
With VALTEC™ for the first time it is possible to adjust the vertical dispersion angle and the tilt angle by adjusting the curvature of the wavefront using one single waveguide.
"Everything was just right, down to the smallest detail. Neutrality, imaging, precision and everything else was exactly on point, as one would expect from a very good studio monitor. The difference, however, is that the CPD18 can do it all at PA volume."

The curvature of the wavefront can be influenced with two lenses arranged in a row between the HF driver and the waveguide, which can be rotated relative to each other. This makes it possible to influence the vertical radiation of the wavefront.
This special solution is so far the only known way to correctly adjust the vertical spread of the wavefront. There is a direct connection between the curvature of the wavefront and the vertical dispersion of the waveguide.
By using VALTEC™ in the VC LINE array it is now possible to adjust the vertical dispersion angle of the individual element to the mechanical angle between the elements. For this purpose the wavefront is more or less curved by two adjustable lens segments, even a completely plane wavefront is possible. The maximum dispersion angle is 15% and is adjustable in increments of 1.5°.
VALTEC™ variable beam (spread), implemented in the VC LINE array.
As a result, there is no overlap between the wavefronts of the different elements, which in turn leads to a homogeneous wavefront of the entire array. The result of a homogeneous wavefront is a line array that behaves like a real point source.
No comb filter effect, and therefore optimum clarity and no level differences in the frequency response are the result.
With the VC LINE and VALTEC™ a new era of line array technology begins.
