About Ashly NXP754

Experience the pinnacle of audio amplification with the NXP754 4-Channel Networkable Multi-Mode Power Amplifier, a sophisticated and powerful solution for professional sound systems. This advanced amplifier is engineered to deliver high-quality audio performance in a variety of demanding environments, including stadiums, arenas, performance venues, worship spaces, and convention centers.

The NXP754 stands out with its versatile Multi-Mode Operation and Selectable Outputs, allowing you to tailor each channel to your specific needs. Whether you require Low Impedance (2, 4, and 8 Ohm) or Constant Voltage (25V, 70V, or 100V) outputs, this amplifier adapts with ease, thanks to its user-friendly DIP-switch configuration.

At the heart of the NXP754 is its Class-D Switching Amplifier Technology, featuring a universal switch-mode power supply with Power Factor Correction (PFC) that operates efficiently across a wide voltage range from 70VAC to 270VAC. This ensures consistent performance regardless of varying power supply conditions.

The amplifier's energy efficiency is further enhanced by the Ashly EMS (Energy Management System), which automatically transitions the unit into a low-power sleep mode, drawing less than 1 Watt when not in use (this feature can be disabled if preferred).

Control and customization are at your fingertips with the integrated Protea DSP, offering 32-bit SHARC DSP Processing at 48kHz or 96kHz sample rates. This comprehensive software control allows for intricate digital signal processing, including matrix and auto-mixing, built-in signal generator for test tones and noise-masking, and swept output load impedance monitoring.

For those seeking the ultimate in precision tuning, the NXP754 is FIR Filter-Ready, compatible with speaker manufacturer's .fir or .csv files loaded via our PneS software. This ensures your system is finely tuned for optimal sound quality.

Remote management is seamless with the Ashly Remote Control via our free iPad app, providing secure wireless control over the network. Customize DSP functions such as gain, mute, matrix, A/B source select, PEQ filter level, and meters with the touch of a finger.

The NXP754 is designed for future-proof connectivity, with an OPDante Option Card for integration into Dante audio networks, expanding its capabilities in digital audio distribution.

Architects and engineers will appreciate the robust build and detailed specifications of the NXP754. Each channel is capable of driving 2 Ohm loads at full power, with a maximum rated output power of 75W per channel across all modes. The unit features comprehensive remote control options, including Ethernet control with a real-time clock for event scheduling, serial data remote control, aux preamp outputs, preset control, and fault condition logic output per channel.

The amplifier's design includes a front panel power switch, rear level controls that can be disabled for security, and a range of LED indicators for status monitoring. With temperature-dependent variable speed forced-air cooling, the NXP754 maintains optimal operating temperatures for reliable performance.

Choose the NXP754 4-Channel Networkable Multi-Mode Power Amplifier with Protea DSP and OPDante Option Card for a durable, high-quality audio solution that professionals trust. Whether you're outfitting a large venue or a sophisticated installation, this amplifier delivers the power and flexibility you need to create an exceptional auditory experience.
