NEXO launches new flagship amplifier

With this product launch, NEXO has completed its new mk2 series of power and processing solutions

NEXO has launched a new flagship amplifier, the NXAMP4x4mk2.

With this product launch, NEXO has completed its new mk2 series of power and processing solutions. These ultra-low distortion Class D amplifiers combine 32-bit/96KHz converters and 64-bit signal processing, improving on the sound quality of NEXO’s mk1 NXAMPs, which have been a core component of the company’s sound systems since 2007.

The NXAMP4x4mk2 is the most powerful amplifier in the range, offering 3,300 watts per channel in four Ohms and 4,500 watts per channel in two Ohms. Weighing 24.9kg in a 3U package, the 4x4mk2 is smaller but more than 12 per cent more powerful than its predecessor.

The NXAMP4x4mk2 also features a new aesthetic, with a silver and black livery on the simplified front panel, which has one knob and a large LCD colour touchscreen. The graphic display enables faster and easier navigation, giving direct access to all essential parameters. All functionality can be set from the front panel, which is user-friendly.

On the back, four analogue 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 analogue fall-back. A native dual Ethernet port offers seamless integration with NEXO’s proprietary NeMo system management software.

The amplifiers can be remote-controlled and daisy-chained via a Remote Control card fitted as standard. Network management is via an Option slot, for which Dante, EtherSound and AES/EBU network cards are available, providing long-term flexibility for customers if protocol preferences change. 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. This amplifier also includes a new modulator chip, developed and patented by Yamaha.

With a mains voltage range of 100-240 volts, the amplifiers can be used anywhere in the world, running on all types of power generators, making them ideal for use in touring. Despite the difficulty in implementation of PFC (Power Factor Correction) technology on large power amps, Yamaha engineers have developed a new circuit for the 4x4mk2 to ensure maximum efficiency and smoother draw, making this the greenest of NEXO’s amplifiers to date.

The NXAMP4x4mk2 can easily fit into a mixed rack with mk1 versions and NEXO’s range of DTD amplifiers as all latencies are exactly the same. It carries a five-year warranty, and NEXO will continue to support the NXAMP4x4mk1 as a legacy product.

Joseph Carcopino, NEXO’s director of R&D, commented: “The NXAMP Series was introduced in 2007, the first collaboration between NEXO and our parent company Yamaha. Although Yamaha has been making amplifiers for 50 years, developing high-power professional models was a new experience for them. Now, after 12 years in this sector, our team has considerably more expertise, which can be seen in NXAMPmk2’s power output, design, user interface and algorithms.

“This is our most environmentally friendly amplifier, using specially engineered Yamaha technology to smooth out consumption spikes, optimise mains management and maximise efficiency. It is smaller and lighter than the mk1 version. Our design brief for the mk2 series was to deliver a better interface and an improved sonic signature, most importantly for this new reference amplifier.”
