About Ashly NXP752

Overwhelm your senses with the powerful and high-quality NXP752 2-Channel Networkable Multi-Mode Power Amplifier with Protea DSP and OPDante Option Card. This advanced audio equipment, designed by the reputable brand Ashly, is engineered to meet the rigorous demands of live sound and fixed installation sound systems in large-scale venues such as stadiums, arenas, performance venues, worship spaces, and convention centers.

The NXP752 amplifier is part of the NX series, available in 2 or 4-channel models, and comes with the added benefits of networkability and DSP. It boasts Class-D Switching Amplifier Technology, featuring a universal switch-mode power supply with Power Factor Correction (PFC) that operates from 70VAC to 270VAC, ensuring durable and reliable performance.

This versatile amplifier offers Multi-Mode Operation with Selectable Outputs, allowing you to choose the desired output mode on each channel. With a simple DIP-switch configuration, you can set it for Low Impedance (2, 4, and 8 Ohm), or 25V, 70V, or 100V Constant Voltage.

The NXP752 is not just powerful but also energy-efficient, featuring Ashly's EMS (Energy Management System) that provides an automatic sleep-mode drawing less than 1 Watt. It also offers Ethernet Control using Protea NE software, serial data control by Ashly programmable remotes or third-party controllers, and aux preamp outputs.

This amplifier is equipped with a Real-Time Clock with Event Scheduler for automatic execution of selected functions and tasks, and Ashly Remote Control via an iPad app for custom design of secure wireless control over the network. It also offers 32-bit SHARC DSP Processing at 48kHz or 96kHz Sample Rates for comprehensive software control of digital signal processing, matrix and auto-mixing, and a built-in signal generator for test tone and noise-masking.

The NXP752 is FIR Filter-Ready, compatible with PneS software that can load a speaker manufacturer's .fir or .csv file for precision tuning. Its robust design includes temperature-dependent variable speed forced-air cooling, ensuring long-lasting performance.
