The Nexo NXAMP4x1 MKII is an updated version of this 4 x channel digital controller / amplifier. As with its predecessor, presets are provided to allow use with the entire range of Nexo speakers and subs. The 4 x channels can be setup to work together, for crossover applications, or as 4 x completely separate channels. Load drive capability down to 2-ohms, allows multiple cabinets to be connected to each of these 4 x channels if required.
As standard, the NXAMP4x1 MKII comes with 4 x high-end balanced analogue XLR inputs, using 'cascaded type' digital-to-analogue converters to offer excellent dynamic range and 32 bit / 96KHz resolution. If required, optional AES/EBU, Ethersound, Dante or AES67 expansion cards can be fitted to allow digital input instead.
The Class D power amplifier stage of NXAMP4x1 MKII uses a unique proprietary LSI chip which delivers upto 4 x 1300W into 2 ohms. A universal power supply capable of operating across a wide voltage range ( 100-240V at 50/60Hz AC ) allows use worldwide. PFC technology used in this power supply ensures high efficiency and smooth current draw.
The user interface of this MKII amp has been dramatically improved compared to the previous model. Instead a the basic LCD screen with fiddly push buttons, a 4.3 inch colour touchscreen is provided, which is not only much more user-friendly but also looks great!
The amp includes a multicore ARM CPU and 3 x multicore DSPs to allow plenty of processing power for future updates. Unlike the previous model which only provided a serial port for firmware updates, this new model also provides 2 x RJ45 data ports. These allow for easier remote control, firmware update and daisy chaining of NXAMP MKII devices.
The amp will fit into a standard 2U of rack-space and the new amp is slightly lighter than the previous model at 15.7KG. Power input uses a locking Powercon NAC3 connector. We supply the amp with a 2M Powercon cable terminated in a 13A UK 3-pin mains plug.
