Nexo NXAMP Powered TDcontrollers

Nexo NXAMP is a major breakthrough in high powered amplification for both fixed and mobile applications.

NXAMP 4x4 is among the industries most powerful amplifiers, providing cost-effective integration of command, control, protection and amplification of all NEXO loudspeaker systems. Lighter, and requiring less rack space than conventional amplifier/processor systems, NXAMP eliminates unnecessary A/D conversion and has the option for EtherSound Networking.
