The NEXO NXAMP 4X4 4-Channel 4000W Power Amplifier is far more complex than a bundled power amplifier and loudspeaker controller. Significant DSP innovations allows multiple digital sense lines to protect at the same time the amplifier and the connected speakers. First the NXAMP4x4 uses a unique dual mains cord, feeding the power supplies with nearly twice the power than most audio amplifiers today, still being extremely easy to connect to any mono or multiple phases mains. To absorb this enormous quantity of current the NXAMP4x4 reveals 4 independent high power full resonant power supplies working in opposite phase, thus canceling noise and lowering EMC.
