FAQs

What speakers can the NXAMP4x4 MK2 drive?
All NEXO speakers. From ID24s to STM mains, the MK2 supports full-range presets for each cabinet.

Can I use it with third-party speakers?
Yes, but you’ll need to configure custom processing. The amp is optimized for NEXO.

How is it different from the 4×1 MK2?
The 4×4 MK2 offers double the power per channel and is better suited for large-format systems.

Is the unit road-ready?
Yes. It’s a 3U rackmount with reinforced chassis and optimized airflow for tough tour conditions.

Does it come with Dante by default?
Yes. Unlike the original NXAMP, the MK2 comes Dante-enabled from the factory.

Can I use it in a 100V line system?
No. It’s designed for low-impedance, high-performance loudspeakers.
