The NXAMP 4X4C MK2 Powered TDcontroller comes available in a 4-channel size and produces an output capacity of 4x4000W under 2Ω, establishing the 4x4 model as one of the most powerful amplifiers to ever be produced.

This model will permit the users to connect a large number of NEXO speaker systems while working on a platform that will maximise their performance. With the optional incorporation of the new generation EtherSound 100 hardware, the NXAMPs will additionally provide an unprecedented capability of Digital Audio networking and Control.

The NXAMP 4X4 Powered TDcontroller is 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 NEXO’s TDcontroller into the amplifier. This full integration of control will provide a safety base and real-time performance that is a first of kind by having all the parameters being controlled by the DSP.

This real-time control will offer the end users the ability to manage the voltage/current/temperature sense lines from the amplifiers output, protecting both the amplifier and its power supply in real time, while simultaneously offering all control parameters required for the speakers.
