Compact 3-way symmetrical line array system ViRAY

ViCOUPLER

All ViRAY drivers are loaded to a common ViCOUPLER

which combines the energy produced from all transducers

to perform as a single source, without phase destruction

achieving a coherent and uniform wavefront. In fact the

ViCOUPLER determines the horizontal on-axis and off-axis

frequency response.

The ViCOUPLER technology integrates 3 main functions:

Waveguide for the Mid/High Planar-wave-driver

Large plane screen panel to avoid backwards

reflections

Phase plug for the 8” drivers for optimized loading

The ViCOUPLER unites all elements to form a complete

entity with complete balance.

Phase-Plug-Loaded cone drivers

Precision phase plugs are integrated into the ViCOUPLER

to ensure acoustically coherent coupling of the low range

In conventional design a backward sound wave from the

mid/high range reflects to the cone onto the low frequency

drivers. The interference between the direct radiating and

reflected waves produce comb filter response.

The ViCOUPLER ensures that sound is reflected in a

coherent manner because the dimension of the reflective

surface is large compared to the wavelength.

In fact a ViCOUPLER loaded array performs as a single

waveguide mounted in a large, flat baffle (screen) without

diffractions. When sound waves from the mid/high range

gather onto the flat surface, it generates a coherent sound

field providing uniform power response and directivity

control over a wide frequency range.

Conventional design ViRAY with ViCOUPLER

providing perfectly consistent coverage down to 350Hz.

This optimizes the horizontal directivity and maximizes the

system efficiency.
