The 4-channel nanoNXAMP4 delivers 4 x 250W utilising highly reliable, ultra-low distortion Class D amplifiers and SMPS with PFC to provide the same sound quality and sonic signature as NEXO’s larger NXAMPMK2 TD Controllers. Processing uses FIR filtering for precise system EQ and linear phase compatibility, with pre-sets available for an edited range of speakers drawn exclusively from NEXO’s popular ID and ePS Series.

On-board mixer and matrix functions further reduce the overall cost of smaller installations, with set up and remote control enabled by an embedded web page that can be accessed via Ethernet or integrated Wi-Fi.
