About Ashly NX754

You can expect unparalleled audio performance with the Ashly NX Series 4-Channel 75W Multi-Mode Power Amplifier, a powerful and high-quality solution tailored for the most demanding live sound and fixed installation systems. Whether you're outfitting stadiums, arenas, performance venues, worship spaces, or convention centers, this advanced amplifier is engineered to deliver reliable and durable service.

Each of the four channels boasts a robust power output, capable of delivering up to 99 watts into 8 ohms, ensuring that your audio is projected with clarity and strength even in large venues or when powering high-impedance speakers. The versatility of the Ashly NX Series is unmatched, with its multi-mode operation allowing for both stereo and mono configurations, providing a flexible audio amplification solution for a variety of professional applications.

The amplifier is equipped with a selectable 80Hz 2nd-order Hi-pass filter, limiter, and input gain per channel, allowing for precise control over your sound. Remote DC level control per channel adds convenience, enabling adjustments from a distance. Extensive protection circuitry safeguards the amplifier, while a continuously variable cooling fan ensures optimal performance without overheating.

Connectivity is made simple and secure with Euroblock input connectors and Euroblock loudspeaker connectors, complemented by a detachable AC mains line-cord connector for easy installation and maintenance. The NX Series adheres to rigorous safety and compliance standards, including cTUVus (pending), CE, FCC, and RoHS.

Incorporating Class-D Switching Amplifier Technology, the NX Series features 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 local power supply variations.

Selectable Outputs on the NX Series allow you to tailor the desired output mode for each channel with ease. Simply set the DIP-switch configuration for Low Impedance (2, 4, and 8 Ohm) or 25V, 70V, or 100V Constant Voltage to suit your specific audio requirements.

Energy efficiency is at the forefront of the NX Series design. The Ashly EMS (Energy Management System) provides an automatic sleep-mode that draws less than 1 Watt when not in use (defeatable), making it an eco-friendly choice that reduces energy consumption without compromising on performance.

Elevate your audio experience with the Ashly NX Series 4-Channel 75W Multi-Mode Power Amplifier, the professional's choice for powerful, high-quality, and reliable audio amplification.
