NEXT-proaudio LAs418A is an active reflex subwoofer that houses two long-excursion, high power B&C 18" drivers, powered by a DPA4000, and designed to offer ultra-low frequencies at a high SPL. Built around a 4000Wrms Class D power amplifier module, with PFC switch mode power supply, the PC-controlled, networkable DSP (24bit/96kHz) with A/D-D/A low noise converters provides eight selectable presets. Presets can be accessed on the front module panel or edited in realtime by a PC using the supplied Soundware II software, via RS485, or USB remote control. An intelligent automatic standby mode is activated when the amplifier detects no input signal. Editable parameters are: input equalization, input delay, input high-pass/low-pass filters, and the “bass enhancer” function. A total of 255 units can be controlled simultaneously by the software. Users can choose from standard or cardioid configurations. The cabinet volume with optimized port tuning can deliver performance down to 24Hz at -10dB, with a maximum peak SPL of 143dB. next-proaudio.com
