NX Multi-Mode Power Amplifiers are designed to meet the most demanding live sound and fixed installation sound systems in stadiums, arenas, performance venues, worship spaces and convention centers.<br><b>Class-D Switching Amplifier Technology:</b> NX features a universal switch-mode power supply with power factor correction (PFC) that operates from 70 to 270VAC.<br><b>Multi-Mode Operation:</b> Selectable Outputs allow you to choose the desired output mode on each channel. Set the DIP-switch configuration for Low Impedance 2, 4 and 8 Ohm), or 25, 70, or 100V constant voltage and you’re set to go.<br><b>Energy Efficiency:</b> NX has power-saving Ashly EMS™ (energy management system) which provides an automatic sleep-mode drawing less than 1W (defeatable).
