GA43 4-ch 750w Power Amplifiers with DSP

GPZA

2x18" Sub + 2x12" Slim Array System (Active)

GPZA is an active system that includes a 2x18” powered subwoofer combined with 2 GH12, our 12” passive coaxial satellites featuring K-array™ SAT® (Slim Array Technology) and a stainless steel cabinet. 

With its built-in 4x1500W RMS amplifier, this system can drive a GPZ passive system in a stereo configuration. It features Powersoft™ DSP and power module, controlled via ethernet with Armonia™ control software.

Thanks to the impressive overall performance and the compact format of the satellites, this system is perfect for high performance outdoor/indoor applications both for rental and permanent installations for touring, large auditoriums, stadia, clubs and pubs, theme parks.

User Tip: optimize the cost and combine the system with the passive model whether it is for stereo configurations or if need to extend the satellite cluster to form an array.
