This unit is capable of delivering up to 2000Wrms with a magnificent precision and punch at incredible SPL, combining optimized acoustic, electro-acoustic and electronic solutions to maximized efficiency. The heart of the LAs15A, is a powerful, light weight, highly efficient Class D power amplifier module, with PFC switch mode power supply. The DPA4000 delivers an impressive sonic punch with perfectly balanced, rich and transparent, sound at any volume. The PC controlled DSP 24bit/96kHz with A/D-D/A low noise converters, provides 8 selectable Presets (7 factory defined and 1 User Defined) that can be accessed by an easy selector, located on the front module panel or real time edited with a PC, using “SOUNDWARE 4.0.1” software. LAs15A subwoofer is versatile enough to address any fixed installation or rental application. Sound Designers, Engineers or Integrators can choose from standard or cardioid configurations, creating a variety of symmetric and asymmetric directivity patterns adapted to each specific solution. The LAs15A can be hanged with LA26 and is capable to power up to 3 LA26 cabinets, which becomes a perfect solution for any indoor/outdoor venue.
