NXAMP 4X4 is an ultra-flexible, true four-channel digital processing and amplification
system delivering an integrated Solution for any Nexo speaker configuration. NXAMP
technology is far more sophisticated than simply a bundled power amplifier and loudspeaker
controller. The application of advanced DSP allows multiple digital sense lines to protect
simultaneously the amplifier and the connected speakers.
The NXAMP 4x4 uses a unique dual mains cord, feeding the Power Supplies with almost twice
the power of that in a conventional amplifier design, while being extremely easy to connect to
any single or multi-phase mains supply. To absorb this enormous current, the NXAMP4x4 uses
four independent, high-power, full resonant Power Supplies working in opposite phase to cancel
noise and lower EMC.
Yamaha EEEngine technology delivers maximum efficiency in drive performance and power, with
the sonic purity of conventional class AB amplifiers, and heat dissipation equivalent to class D.
Dual-CORE DSPs take care of amplifier protection and optimisation, while raising the processing
standard of Nexo proprietary loudspeaker management technology to higher levels of sonic
performance and reliability.
Additional features include full computerless front-panel operation and on-the-fly independent
loudspeaker per output selection or load monitoring through GPIO or Ethersound
NEXO are among Europe's top three sound reinforcement loudspeaker manufacturers. Based in Paris, the company was founded in 1979 by Eric Vincenot and Michael Johnson. Both are still actively involved with the company and Eric maintains the unique role of Chairman and R&D Director. What separates NEXO from the competition is an innovative, integrated systems approach to loudspeaker research and development. Each new product/system begins with sophisticated computer simulations, executed by our highly specialised proprietary software. After the design specification stage, the entire electro-acoustic signal chain is thoroughly modeled and product performance rigorously evaluated to maximize system performance in an incredibly short time frame.

Processor units, often simply known as a DSP audio processor, are a sound-processing device that alters the sound of auditory signals. The processing of the audio signals may be either digital or analog. The analog processing involves the direct operation of the electrical signal while the digital processing involves the mathematical operation on the digital representation of the audio signal. The audio signals are typically known as sound waves that are transmitted through the air. These sound waves are measured in decibels or bels. These audio signals need processor units especially in radio broadcasting because the processor units link the transmitter with the rest of the sound system devices. There are various methods involved in the processing of both analog and digital signals. These include the following: storage, compression, transmission, equalization, noise cancellation, enhancement, level compression, echo, filtering and many more. Analog processing is the physical alteration of the uninterrupted signal by modifying the voltage, the current or the charge with the use of electrical means. In earlier times, analog processing was the only method being used to modify signals before digital technology came into existence. With the evolution of computers and software, digital sound processing became the alternative to analog processing. The digital processor units use digital circuits like the microprocessors and computers to process audio signals. Digital processing deals with sound waves represented by binary numbers and deals with the sequence of these numbers. Nowadays, audio systems typically use the digital processing method because it is more powerful and proficient compared to analog signal processing.
