The NXE Series 4-Channel Networkable Multi-Mode Power Amplifier from Ashly comes pre-installed with OPDAC4 internal 4-Channel DAC with selectable HPF and OPDante Dante Network Audio Interface cards. The OPDante card enables access to digital audio networks at low latencies (83.3 μs) over fast Ethernet. It can be installed in the rear card slot of NXE series amplifiers. Signal can be routed from other Dante enabled devices by simply connecting a Cat5e or Cat6 cable to the card's primary or secondary (redundant) Ethernet ports. The amplifier is capable of driving 2 Ohms loads at full power and offers a maximum rated output power of 400W per channel at Low Z and 70V, and 100V modes. In addition, the amplifier is suitable for use in performance venues, stadiums, arenas, convention centers as well as schools, store fronts, and places of worship.
The multi-mode amplifier features an automatic but defeatable sleep mode consuming <1W, and instant standby mode controlled by contact closure or software. A switch mode power supply can auto-detect 120 or 240 VAC mains, and a Neutrik powerCON is used for the AC cord. Each channel features a selectable output mode of Low Z, 70V, or 100V, an 80 Hz high-pass filter, input limiter, and input gain settings of 26 dB, 32 dB, 38 dB, or 1.4V. Each channel comes with a remote DC level control.
The amplifier comes with Neutrik XLR/TRS combo jack and Euroblock input connectors and Neutrik speakON output connectors. The unit features a front panel power switch and level controls that can be disabled. The LEDs indicate Protect, Sleep, Disabled, Com, and Bridge mode status, as well as Temperature, Output Current, Output Signal, and Clipping/Mute status per channel. In addition, the power amplifier features an Ethernet control with a real-time clock for event scheduling.
The power amplifier is equipped with serial data remote control, aux preamp outputs, preset control, and fault condition logic outputs. It also features a temperature dependent variable speed forced-air cooling. In addition, the amplifier can be mounted on a standard 19” rack.
