The NXAMP4X4MK2 4-channel 4500W powered TD controller represents the pinnacle of collaboration between NEXO's expertise in DSP control and Yamaha's world-class power amplification technology. Combining four ultra-low distortion Class D amplifiers with integrated 24-bit/96 kHz converters and 64-bit signal processing, this compact 3U unit delivers articulate, transparent, and rich audio for professional sound reinforcement.
Designed for touring and fixed installations, the NXAMP4X4MK2 provides rapid deployment and intuitive control. A large color touchscreen on the front panel gives immediate access to all essential parameters, while the rear panel features a full suite of connectivity options, including analogue inputs, optional digital cards (Dante, EtherSound, AES, and Dante + AES), RS232 serial, GPIO, and Speakon outputs for all four channels. Native dual Ethernet ports enable remote control and amplifier daisy-chaining via NEXO's NeMo software.
The NXAMP4X4MK2 is engineered for worldwide operation, featuring a 100-240V mains range and robust power supplies that utilize Power Factor Correction (PFC) technology for maximum efficiency and reduced stress on power networks. Lightweight yet powerful, it delivers 4 x 4500W while weighing just 24.9 kg, and its multi-core DSP architecture provides a future-proof platform capable of hosting new algorithms and firmware updates for years to come.
