About Ashly NXP1504

Under the umbrella of advanced audio equipment, the NXP Series 4-Channel 150W Networkable Multi-Mode Power Amplifier with Protea DSP Software Suite stands out as a powerful, high-quality, and efficient solution for demanding live sound and fixed installation sound systems. This durable amplifier is ideal for large-scale applications in stadiums, arenas, performance venues, worship spaces, and convention centers.

The NXP Series Amplifier boasts a selectable 80Hz 2nd-order Hi-pass filter, limiter, and input gain per channel, ensuring optimal sound quality and control. Its remote DC level control per channel and extensive protection circuitry further enhance its performance and reliability.

This advanced amplifier is equipped with an Ethernet port for software control and monitoring of amplifier functions, complete with a front panel COM activity LED. It also features a serial data port compatible with Ashly WR-5 and RD-8C programmable remote controls, offering additional flexibility and control.

The NXP Series Amplifier is designed with energy efficiency in mind, featuring an Instant Standby Mode that reduces idle power consumption by 40%. This mode can be triggered by contact closure, software control, or an event scheduler.

The amplifier also offers comprehensive software-controlled DSP, including dynamics, gain, equalization, matrix mixer, crossover, delay, and metering. For added convenience, select DSP functions such as gain, matrix, A/B source select, PEQ filter level, and meters can be controlled via an iPad.

The NXP Series Amplifier is built with Class-D Switching Amplifier Technology and features a universal switch-mode power supply with Power Factor Correction (PFC) that operates from 70VAC to 270VAC. Its multi-mode operation and selectable outputs allow you to choose the desired output mode on each channel, providing flexibility for low impedance or constant voltage settings.

This amplifier is also equipped with Ashly EMS (Energy Management System), an automatic sleep-mode that draws less than 1 Watt, contributing to its energy efficiency. Additionally, it offers real-time clock with event scheduler for automatic execution of selected functions and tasks, and Ashly Remote Control via an iPad app for secure wireless control over the network.

With its 32-bit SHARC DSP Processing at 48kHz or 96kHz Sample Rates, the NXP Series Amplifier offers comprehensive software control of digital signal processing, matrix and auto-mixing, and a built-in signal generator for test tone and noise-masking. It's also FIR Filter-Ready, compatible with a speaker manufacturer's .fir or .csv file for precision tuning.

In conclusion, the NXP Series 4-Channel 150W Networkable Multi-Mode Power Amplifier with Protea DSP Software Suite is a robust, versatile, and efficient solution for professional audio amplification needs.
