NEXO NXAMP4x1MK2 4x1300W Network Powered Digital Amplifier Controller

The NEXO NXAMP4x1MK2 is a network-powered digital amplifier controller designed for touring and installed loudspeaker systems that require integrated digital signal processing and amplification in a single 2U chassis.

It delivers 4x1300 W of amplification with a frequency response of ±1 dB from 10 Hz to 20 kHz, suitable for driving multiple loudspeaker channels with consistent performance across the audio band.

Connectivity includes 4x balanced analogue inputs on XLR3, a dedicated DB-9 connector for DPU connection, and a DB-25 connector offering 5 inputs and 8 outputs or DMU connection, alongside an expansion slot for networking and digital audio cards. Control is handled via a rotary encoder with push and backlight, a 4.3-inch WQVGA colour touchscreen (480 x 272), and an RS232 port.
