NEXO NXAMP Powered Digital TDcontrollers:

NEXO GEO S8
 

Nexo NXAMP Powered Digital TDcontrollers Overview:

The primary objective of the strategic alliance created between NEXO and Yamaha in 2005 was to create products that would profoundly elevate system solutions in the sound reinforcement industry. NEXO was seeking a solution that would provide full optimisation and performance of its speaker systems.

Through the combination of NEXO’s renowned expertise in producing top-of-the-line sound reinforcement products and Yamaha’s 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 NEXO’s 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.

Nexo NXAMP Technology

The NXAMP 4X1 & 4X4 Powered TDcontrollers, available in two 4-channel sizes produce an output capacity of 4 x 1300W under 2 Ohms for the 4 x 1 model and 4 x 4000W under 2 Ohms for the 4x4 model; establishing the 4x1 model as one of the most versatile amplifiers and the 4x4 model as one of the most powerful amplifiers to ever be produced. These models will permit the users to connect a large number of NEXO speaker systems while working on a platform that will maximize 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.

Processing and Control - The new generation signal processor in the NXAMPs is identical on both models, and derived from the NX242 TDcontroller. The processing power has been increased on both CPU and DSP.

The NXAMPs utilise twin DSPs, with a total processing power that is 3.5 times the processing power of an NX242 fitted with an ES-4 NXtension board. Amplifier output is now sensed in both voltage and current and 24bit converters execute these measurements. The latest generation audio converters provide enhanced dynamic range with low latency (500us) analog input to output, in "flat" mode.

Clean and Cool EEEngine - One of the primary objectives of Yamaha’s EEEngine technology is to deliver maximum efficiency in drive performance and power, while providing the audio quality of traditional class AB amplifiers that have an equivalent heat dissipation of class D amplifiers. The results have illustrated a 50% reduction in power consumption which provides outstanding sound quality.

Robust, Rugged Power Supplies - The power supplies of the NXAMPs are SMPS (Switch Mode Power Supply) full resonance types with half bridge converters. This exceptional design offers the advantages of being smaller in size, improved power efficiency, and decreased heat generation. The design additionally minimizes noise via its Zero Crossing Switch (ZCS) technology.

The NXAMP4x4 employs four times the structure of a monaural amplifier with four separate power supplies that present a high power capacity with a low load drive. In addition, on both models, two converters work synchronized in the opposite phase, thus cancelling noise. The benefits will include unrivalled sonic performance and low electro magnetic emissions.

Ferocious Final Stage (with Protection) - The output transistors in the final stage use thin chip technology with a small thermal resistance. Moreover, the model used here is a custom version with a maximum voltage now reaching 300 Volts. The final stage of the NXAMP 4x4 uses nine such transistors in parallel for a maximum of 135Amp output current capacity.

Optional EtherSound™ Remote Control -The rear panel expansion slot allows the easy addition of an NXES104 EtherSound board. This new generation of EtherSound hardware offers device-to-device communication and powerful new functions including: ring topology and a third remote control port that will allow a computer to be connected anywhere in the chain when both EtherSound ports are already being utilized.
