What is it? A family of Class-D amplifiers in 2- and 4-channel versions combining light weight, efficiency and flexibility. Details Delivering up to 12kW of power while drawing less than 1W in sleep mode, nX amplifiers are available with selectable high-Z (70/100V) or low-Z output on each channel. nX model variants include the addition of Ethernet control and onboard Protea DSP with load monitoring to meet the requirements of modern fixed installations and live sound applications in stadiums, arenas, houses of worship and convention centres. The three nX amps series offer feature sets that build upon each other. The base nX amplifiers are available in two- or four-channel versions at 3kW or 1.5kW per channel into 2 Ohms and feature a defeatable automatic sleep mode. nXe series amps add Ethernet control, serial data control, aux preamp outputs, programmable standby mode, preset recall, fault condition logic outputs, event scheduling and optional network audio and digital audio capability (CobraNet or AES3). Finally, nXp series amps include all the nXe features plus onboard 32-bit SHARC Protea DSP processing (48 or 96kHz sampling rate) and precision swept load-impedance monitoring. Additional features include multiple independent power supplies for increased channel separation and reliability, front-panel power switch and level controls (defeatable in nXe and nXp models), front-panel LEDs for temperature, current, signal, clip, mute, bridge mode, protect, sleep etc, plus Neutrik Combo XLR – 1/4" TRS jack and Euroblock input connectors with Neutrik SpeakON twist-locking speaker connectors. And another thing… nX amplifiers incorporate rear-panel DIP switches per channel for selection of high-pass filter, limiter, input gain and High-Z or Low-Z speaker output configuration.
