Overview
The NEXO NXAMP4x2mk2 is a four channel powered TD controller, combining Class D amplification with NEXO's speaker processing in one 2U box. It is rated at 4 x 2500 W and has phase linear presets for every NEXO cabinet, so you load the right preset and the system is protected and tuned. It is NEXO's recommended amp for GEO M10, P12, P15, L15 and L18, which makes it the workhorse of most NEXO systems.
All key settings are on the 4.3 inch colour touchscreen, and the native dual Ethernet card lets you control and monitor amps from NEXO's NeMo software on Windows, macOS or iOS. Four analogue XLR inputs are standard, and the expansion slot takes optional Dante, AES/EBU, Dante + AES or EtherSound cards with automatic analogue fall back. It suits churches, theatres, installers and hire companies running NEXO systems.

Forefront Tip
The NXAMP4x2mk2 runs up to three GEO M10 or two P12 or P15 per channel, so one 2U amp can power a full left and right system with subs. Add a Dante card if your desk is on a Dante network, and keep the analogue inputs patched as a backup, because the amp falls back automatically if the network drops.
