VCA Line Array Configurations

The VCA family can be deployed in extended cardioid, long throw, or beam split configurations, so you can adapt your system to any environment and situation.

Couplers within our line array systems provide you with variable horizontal coverage plus the power to focus on directivity, eliminate unwanted reflections, and choose the ideal dispersion pattern for your venue. Optional SC2-F low-frequency extensions can give you even more deployment options.

Line arrays can inherently be cardioid-only or deployed in a more versatile method.

Cardioid-only line arrays incorporate actively driven transducers with the sole
purpose of providing cancellation towards the rear. The disadvantage is that this increases the size and weight, and causes nonlinear phase response. Plus, the need for additional amplifiers makes it almost impossible to use in some circumstances.

CODA Audio versatile line arrays however can be arrayed in cardioid, extended cardioid, long throw, or beam split configurations, with a perfect solution for any situation.

Full-range Cardioid radiation pattern using SC2:

When an array of SC2-F low-frequency extensions is flown behind the line array, it is possible to create either a cardioid radiation pattern or an extended cardioid pattern with increased rejection.

Cardioid Array

(example AiRAY + SC2-F flown behind the line array):

The cardioid radiation pattern is achieved by overlapping in the 45 – 200Hz frequency range of the two system elements – the same principle of operation as an end-fire subwoofer array.

Extended Cardioid Array

(example AiRAY + SC2-F flown behind the line array):

This cardioid deployment can provide even more powerful rejection, by rotating every other SC2-F enclosure and using extended cardioid presets on the SC2-F subwoofers. This configuration is comparable to end-fire array with three sources placed one behind the other (line array/low frequency extension front/low frequency extension rear).

The whole system is working together to throw the energy forward and provide wide-band cancellation towards the rear.

Long Throw Configuration

The SC2-F bass extensions overlap between 45 and 200Hz. This physical increase in array length further enhances the long throw at lower frequencies. This configuration provides a smaller tonal variation from the front to the rear of a larger audience listening area.

Beam Split Configuration

The SC2-F low extensions are placed between the other line array elements, and parts of the vertical dispersion of the system can be split into two separate beams. This focuses the power and energy exactly where it needs to go, plus avoids the hard edge of a balcony in a theatre that would otherwise cause undesirable reflections.

Variable Horizontal Dispersion:

All CODA line arrays utilize variable horizontal coverage.
For example: CiRAY provides variable horizontal dispersion of symmetrical 60°, 90° or 120° as well as asymmetrical 30°+45°, 30°+60° or 45°+60°

120° Horizontal Directivity

90° Horizontal Directivity

60° Horizontal Directivity
