ASHLY NX8004 Power Amplifier 4 x 800 Watts @ 2 Ohms

Product Overview

The Ashly NX8004 is a four-channel Class-D multi-mode power amplifier delivering 800 watts per channel across all load configurations — 70V, 100V constant-voltage, and 2, 4, or 8 ohm low-impedance. As a base-level NX series amplifier without network control or onboard DSP, the NX8004 provides reliable multi-zone output for commercial AV installations where signal processing and control are handled externally. The consistent 800W/ch output across all impedances makes it a practical choice for multi-zone 70V amplifier rack-mount applications in houses of worship, auditoriums, convention centers, and commercial facilities. The universal switch-mode power supply accepts 120V or 230V AC, simplifying international project deployment.

Product Description

The Ashly NX8004 commercial AV amplifier delivers straightforward four-channel multi-mode amplification in a rack-mount chassis, without the added complexity of network control or DSP. It is well-suited for commercial installations where a separate DSP processor handles signal processing and the amplifier's role is purely to drive speakers at high output with high reliability. Each of the four channels is independently configurable for 70V or 100V constant-voltage or low-impedance operation at 2, 4, or 8 ohms via rear panel DIP switches, requiring no software for basic setup. The uniform 800W/ch output across all impedances simplifies zone capacity planning: each channel provides the same headroom whether driving a 70V tap load or a low-impedance speaker cabinet. Class-D switching amplifier technology with switch-mode power supply delivers high efficiency and a lightweight chassis appropriate for permanent rack-mount commercial installation. Multiple independent internal power supplies provide improved channel separation and reliability across all four channels simultaneously. The front panel level controls and power switch can be disabled to prevent unauthorized adjustments in publicly accessible installations. Continuously variable cooling fans minimize fan noise during low-demand periods. The Ashly EMS (Energy Management System) provides automatic sleep mode drawing less than 1 watt during idle periods. Remote DC level control per channel supports integration with external zone control systems. The NX8004 is TAA compliant, certified RoHS, cTUVus, CE, and FCC, manufactured in the United States, and carries a 5-year limited warranty.

Technical Specifications

Frequently Asked Questions

Does the NX8004 include network control or DSP?

No. The NX8004 is a base-level NX series amplifier without Ethernet control or onboard DSP. Output mode is configured per channel via rear panel DIP switches. For network control, consider the NXE8004. For DSP, consider the NXP8004 series.

Can the NX8004 drive 70V and low-impedance speakers?

Yes. Each of the four channels is independently configurable for 70V or 100V constant-voltage or 2, 4, or 8 ohm low-impedance operation via rear DIP switches.

Does the NX8004 work on international power?

Yes. The switch-mode power supply auto-detects 120V or 230V AC input, making it suitable for international deployments without a separate power converter.

Can the front panel controls be locked?

Yes. The front panel power switch and level controls can be disabled, preventing unauthorized adjustments in installations where the amplifier rack is accessible to non-technical personnel.

What is the NX8004 warranty?

The NX8004 carries a 5-year limited warranty and is manufactured in the United States. It is TAA compliant and certified RoHS, cTUVus, CE, and FCC.
