ASHLY NX754 Power Amplifier 4 x 75 Watts @ 2 Ohms

Product Overview

The Ashly NX754 is a four-channel multi-mode power amplifier delivering 75 watts per channel across all load configurations — 25V, 70V, 100V constant-voltage, and 2, 4, or 8 ohm low-impedance — without network control or onboard DSP. As a base-level NX series amplifier, the NX754 is configured via rear panel DIP switches and designed for use with external DSP processors in commercial AV installations requiring four independent output zones with 25V constant-voltage support. The consistent 75W/ch across all load types including 25V makes the NX754 well matched for compact commercial installations, meeting rooms, retail spaces, and educational facilities using 25V speaker systems that require four independent zones of modest-output amplification without integrated network or signal processing overhead.

Product Description

The Ashly NX754 commercial power amplifier delivers four-channel multi-mode amplification at 75W/ch in a rack-mount chassis. Each of the four channels is independently configurable for 25V, 70V, or 100V constant-voltage or 2, 4, or 8 ohm low-impedance operation via rear panel DIP switches, requiring no software for initial setup. With 75W/ch across all load types including 25V, the NX754 covers compact commercial zones, meeting rooms, retail spaces, and educational facilities where four independent output zones with 25V speaker systems are needed and processing is managed externally. The switch-mode power supply auto-detects 120V or 230V AC input for international deployment compatibility. Class-D amplifier technology delivers high efficiency in a compact chassis. Multiple independent internal power supplies provide improved channel separation when all four channels operate simultaneously. Continuously variable cooling fans reduce audible fan noise during standby and low-load operation. Front panel level controls and power switch can be disabled to prevent unauthorized adjustments in public installations. Remote DC level control per channel supports integration with external zone management hardware. The Ashly EMS provides automatic sleep mode drawing less than 1 watt during idle periods. The NX754 is manufactured in the United States, TAA compliant, and carries a 5-year limited warranty.

Key Features
