Yamaha Announces Two New NXAMP MK2 NEXO Amplifiers

BUENA PARK, Calif. (October 27, 2017)—Yamaha Professional Audio has announced two new additions to the NEXO range of NXAMP TDcontrollers. The NXAMP4x2 MK2 and NXAMP4x1 MK2 amplifier models are the result of close collaboration between R&D engineers from NEXO and parent company Yamaha Corporation Japan.

            The new NXAMP4x1 MK2 and NXAMP4x2 MK2 present NEXO expertise in DSP control in lighter, sleeker 2U packages with front panel touch screen control enabling faster and easier navigation, and giving direct access to all essential parameters including: Array EQ, Mute and Meters, EQ Detail, User EQ,

Inputs, Load Monitoring, Log, Scene, Setup, System Headroom, as well as Volume, Gain and Delays.

            A native, dual Ethernet port offers seamless integration with NEXO proprietary NeMo system management software. Amplifiers can be remote-controlled and daisy-chained via a standard Remote Control card with optional Dante, EtherSound and AES/EBU network cards available. Four high-end analog inputs use cascaded converters for low output noise, and four digital inputs are available through the rear panel expansion card slot offering optional AES/EBU, EtherSound™, Dante™ or AES67 inputs, all with automatic analog fall-back. In addition to the expansion card slot, other rear panel connectivity includes RS232 serial and GPIO ports along with Speakon outputs for each of the four channels.

            “Since its launch ten years ago, the NXAMP range of controller/amplifiers have proven their consistency, quality and reliability – a testament to the expertise of the Yamaha and NEXO engineering teams,” states Marc Lopez, director of marketing, Commercial Audio products, Yamaha Professional Audio division. “The new amplifiers are poised to contribute greatly to both the touring and fixed installation markets.”

            Available in 4 x 1300W and 4 x 2500W @ 2 ohms and weighing in at just 35 lbs. and 36.5 lbs., respectively, the ultra-low distortion Class D amplifiers combine 32-bit/96KHz converters and 64-bit signal processing to deliver significant advances in sound quality over the already highly-regarded original NXAMPs. They feature a universal power supply (100 – 240 Volts) using PFC (Power Factor Correction) technology for maximum efficiency and smooth current draw.

            The NXAMP4x2 MK2 is a new design in the NXAMP range, and is ideal for the NEXO GEO Series of compact line array systems and PS Series cabinets.             The NXAMP4x1 MK2 replaces the NXAMP4x1 model, which NEXO will continue to support as a legacy product.

            The new amplifiers will be available in early 2018.
