Description

We are offering three amplifiers from our demo and demonstration stock; some of the units have not been used at all. All amps are fully functional and show no signs of use. The current software has been installed and subsequently tested. A total of 3 units are available. When purchasing at least 2 amps, the net price is €6,450 per unit. DMU, DPU, cable sets and case can optionally be purchased additionally as a complete set, but are not included in the stated price. Individual sale of DMU, DPU and cable set is not intended! ________________________________________________________________________ The NXAMP is not merely a combination of power amplifier and loudspeaker controller. Advanced DSP programming works with several digital measurement paths and thereby enables simultaneous protection of the amplifier and the connected loudspeakers. The NXAMP4x4 features an exceptional dual power cable that supplies the power supplies with almost twice the power compared to many current power amplifiers. Nevertheless, the unit can be connected easily to mains supplies with any single- or multi-phase configuration. Four independently operating full-resonance converter power supplies are integrated to process these high amounts of current. They operate in opposite phase, thereby reducing interference and contributing to improved electromagnetic compatibility (EMC). The power amplifier technology used is based on specially selected, custom-manufactured assemblies and consistently advances Yamaha's EEEngine technology. The result combines the sonic clarity of classic Class-AB amplifiers with heat dissipation at Class-D level. Two Dual-Core-DSPs not only optimize and protect the power amplifier, but also raise loudspeaker management technology to an even higher level of quality. This optimizes sound, performance and operational reliability equally. For practical use, features include complete operation directly from the front panel without a computer, fast and independent selection of the loudspeakers for each output, as well as load monitoring via GPIO and networks such as EtherSound™, AES/EBU and Dante™. This makes the NXAMP4x4 suitable for numerous demanding tasks and installations. Key Features Highly flexible true four-channel DSP processing and power amplification, optimally matched to all NEXO loudspeakers. One of the most powerful four-channel power amplifiers in the audio sector. Economical combination of loudspeaker management, signal processing, protection circuits and power amplification for all NEXO loudspeaker systems. Less weight and space requirements than comparable combinations of amplifier and processor. No additional A/D conversion required. Optional network cards for Dante™, EtherSound™ and AES/EBU.
