Nexo NXAMP 4x4 Powered TDcontroller, NXAMP technology is far more complex than a bundled power amplifier and loudspeaker controller. More than two years of research yielded significant DSP innovations which allow multiple voltage/current/temperature sense lines, from the amplifiers output, to protect both the amplifier and power supply.

Through the combination of NEXOs renowned expertise in producing top-of-the-line sound reinforcement products and Yamahas internationally acclaimed professional audio division, two years of collaborative research using the latest-generation development and research tools have yielded a major breakthrough in high-powered amplification for both fixed and mobile applications.

The NXAMP 4X1 and 4X4 Powered TDControllers are based on an innovative design that will provide the full integration of speaker and amplifier control with output capacities that will allow end users a cost-effective solution.

The innovative control structure implemented into the NXAMP is via the latest generation of NEXOs TDcontrollers. This full integration of control will provide a safety base and real-time performance that is the first of its kind, having all the parameters controlled by the DSP. This real-time control will offer end users the ability to manage the voltage/current/temperature sense lines from the amplifier's output, protecting both the amplifier and its power supply in real time, while simultaneously offering all control parameters required for the speakers.

NXAMP DSP Protection includes:

Power-on protection (smooth start-up with in-rush limitation)
Power-off protection (clean shut-down procedure)
Peak Voltage limiter (clip limiting)
Peak Current limiter
VHF protection
Integrate current limiter
DC offset protection
Short circuit protection
Fan speed control
Power Amp overheat protection
SMPS overheat protection
SMPS fault protection
Power cable monitoring
