-2-Channel -70V, 100V Output, All Channels Driven
Ashly nX1.52 -1250W 2-Channel Power Amplifier Ashly’s new line of nX Power Amplifiers feature lightweight, energy efficient Class D switching amplifier technology combined with a switch mode power supply. The nX amplifiers are available in three product families designed to meet the most demanding live sound and fixed installation sound systems in stadiums, arenas, performance venues, worship spaces and convention centers. nX Series is the base level amplifier, available in either 2 or 4-channel models. Use rear panel DIP switches to program each channel output for either High-Z (70V or 100V Constant Voltage) or Low-Z (stable down to 2 Ohms) operation. When in Sleep Mode, the nX amplifiers draw less than 1 Watt.
