The LAs418A houses two long excursion and very high power B&C 18" drivers powered by the DPA3000 (power module with DSP). This unit is capable of delivering up to 3200Wrms with a magnificent precision and punch at incredible SPL, combining optimised acoustic, electro-acoustic and electronic solutions to maximised efficiency.



The heart of the LAs418A, is a powerful, light weight, highly efficient Class D power amplifier module, with PFC switch mode power supply from Powersoft. The DPA3000 delivers an impressive sonic punch with perfectly balanced, rich and transparent, sound at any volume. The PC controlled DSP 24bit/48kHz with A/D-D/A low noise converters, provides 4 selectable Presets (3 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 Armonia software. This allows to easily customize the sound program, for various applications or different venues. An intelligent automatic standby mode is activated when the amplifier detects no input signal, saving energy and extending the expected work life. With Powersoft Armonia software is possible to edit the 3 pre-loaded Presets and store it on the user defined memory location. Editable parameters are: Peak Filters, High-Shelf/Low-Shelf Filters, Band-Pass/Band-Stop Filters, All-Pass Filters, High-Pass/Low-Pass Filters, Input delay, polarity and gain. LAs418A can be used on the same software platform as the N-RAK and PXA8001.



LAs418A 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 cabinet volume with optimized port tuning featuring extremely high peak-to peak excursion capability, is capable to deliver true sub performance down to 24Hz at -10dB. Providing low frequency resolution and a maximum Peak SPL of 143dB in a 89kg, front loaded, bass reflex enclosure and measuring 1030mmx516mmx920mm (WxHxD), the new subwoofer version incorporates 8 handles, housed within a multi-laminate birch plywood enclosure and finished in textured black semi-matte coating.
