NEXO nanoNXAMP4 4-Channel Powered TD Controller

The nanoNXAMP4 is a high-performance, compact, powered TD controller amplifier designed specifically for small to medium NEXO installations. Delivering 4 x 250 watts at 4 ohms, it uses ultra-low distortion Class D amplification and a universal SMPS with PFC, ensuring the same sonic signature and reliability as NEXO's larger NXAMP MK2 controllers.

Advanced FIR filtering provides precise system EQ, linear phase response, and optimized loudspeaker protection, with factory presets available for selected NEXO ID and ePS Series speakers. An integrated mixer and matrix significantly reduces system cost and complexity by eliminating the need for external processors or mixers.

Designed for modern installations, the nanoNXAMP4 features an embedded web server for setup and remote control via Ethernet or integrated Wi-Fi, accessible from any computer or smartphone. With flexible analog and digital inputs, GPIO, wall controller support, and third-party control system compatibility, it delivers powerful performance, flexibility, and control in a compact 1U half-rack format.
