GA43 4-ch 750w Power Amplifiers with DSP

GH412

4x12" High Efficiency Coaxial Slim Array

This passive 4x12” coaxial array element features a compact stainless steel, weather resistant cabinet that benefits from K-array™ SAT® (Slim Array Technology) and PAT® (Pure Array Technology).

Its cardioid dispersion pattern limits the loss of energy in unwanted directions. More units can be joined together to form a line array and scale up the system.

Designed for high performance outdoor/indoor applications both for fixed and moving installations for live events, auditoriums, transportation facilities, stadia, theme parks and and clubs.

Stainless Steel Design

GH12 is made out of Grade 430 stainless steel, an alloy that combines good formability and finish capabilities with an excellent resistance to pitting and corrosion. 

The high density and neutral sonic characteristics of this material make it a perfect choice for applications that require compact design, resistance to adverse conditions and high sound performance.

Pure Array Technology ®

The sound sources in the array are identical, really close and perfectly coupled producing a highly directive sound beam that is very wide on the horizontal plane and very narrow on the vertical plane.

The amount of energy sent towards the ceiling and the floor is then minimized improving the intelligibility in highly reverberant venues like houses of worship and conference rooms.

Such a focused sound beam is able to cover a long distance uniformly: both the audience located in front of the array and at the back of the venue will experience the same tonal balance without the need of several delay lines.
