The nX models are designed to meet the most demanding live sound and fixed installation sound systems in stadiums, arenas, performance venues, worship spaces and convention centers.
The Ashly nX4002 is a 2 channel multi-mode amplifier capable of driving 2 Ohm loads at full power. The maximum rated output power is 400W per channel at Low Z, 70V, and 100V mode. There is an automatic but defeatable sleep mode consuming <1W. A switch mode power supply shall auto-detect 110 – 120VAC or 220 – 240VAC mains, and a Neutrik® powerCON shall be used for the AC cord. Each channel has selectable output modes of Low Z, 70V, or 100V, an 80Hz high-pass filter, input limiter, and input gain settings of 26dB, 32dB, 38dB, or 1.4V.
Each channel has a remote DC level control. Input connectors are Neutrik® XLR/TRS combo jacks and Euroblock, while output connectors are Neutrik® speakON. The unit has a front panel power switch and level controls that can be disabled. LEDs indicate Protect, Sleep, Disabled, and Bridge mode status, as well as Temperature, Output Current, Output Signal, and Clipping/Mute status per channel. The amplifier has temperature dependent variable speed forced-air cooling. The unit weighs <21.5 lbs (9.75 kg), measures 19"W x 3.5"H x 16.8"D (483 mm x 89 mm x 428 mm), and mounts in a standard 19" rack.
