ASHLY NX3.04 Multi-Mode Power Amplifier 4X3KW At2 Ohms, 2KW At4 Ohms, 1250W At8

Product Overview

The Ashly NX3.04 is a four-channel Class-D multi-mode power amplifier delivering 3,000 watts per channel at 2 ohms, 2,000 watts at 4 ohms, 1,250 watts at 8 ohms, and 2,450 watts at 70V constant voltage. Designed for commercial AV installations requiring high output across both low-impedance and constant-voltage speaker systems, the NX3.04 suits stadiums, arenas, performance venues, houses of worship, and convention centers. As the base-level model in Ashly's NX series, it provides reliable multi-zone 70V amplifier rack-mount performance without network or DSP complexity, making it a practical choice for installations where external DSP handling is already in place. The universal switch-mode power supply accepts 120V or 240V AC, simplifying deployment across domestic and international projects.

Product Description

The Ashly NX3.04 commercial AV amplifier is built around Class-D switching technology combined with a switch-mode power supply, producing substantial output power in a rack-mount form factor while maintaining high energy efficiency. Each of the four channels can be independently configured for constant-voltage operation at 70V or 100V, or low-impedance operation stable down to 2 ohms, using rear panel DIP switches — no software required for basic output mode selection. This makes the NX3.04 a straightforward commercial installation amplifier for contractors and system integrators who need dependable high-power output without a full networkable amplifier platform. The front panel includes power switch and level controls that can be disabled to prevent tampering in publicly accessible installations. Multiple independent internal power supplies deliver improved channel separation and operational reliability across all four channels simultaneously. Continuously variable cooling fans adapt airflow to actual thermal load, reducing noise during low-demand periods such as in conference rooms or training rooms. Ashly's EMS (Energy Management System) provides automatic sleep mode drawing less than 1 watt when no signal is detected, supporting energy efficiency in commercial facilities with extended idle periods. Remote DC level control per channel (on the 2RU model) allows integration with external volume control systems. Genuine Neutrik connectors on input and output ensure secure, long-lasting terminations appropriate for fixed commercial installations. The NX3.04 meets safety and compliance requirements with cTUVus, CE, FCC, and RoHS certifications, and carries a 5-year limited warranty backed by U.S. manufacturing.

Technical Specifications

Frequently Asked Questions

Does the NX3.04 include DSP or network control?

No. The NX3.04 is a base-level amplifier without onboard DSP or network connectivity. Output mode and basic settings are configured via rear panel DIP switches. For installations requiring DSP and network control, consider the NXP series amplifiers.

Can the NX3.04 drive 70V and low-impedance speaker systems?

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

What is the power output of the NX3.04 at 70V?

The NX3.04 delivers 2,450 watts per channel at 70V, making it well-suited for large constant-voltage distributed speaker runs in venues with many tapped speakers.

Does the NX3.04 work on international power?

Yes. The switch-mode power supply automatically detects and accepts 120V AC or 230V AC input, making the NX3.04 suitable for international deployments without a separate power converter.

What is the NX3.04 warranty and compliance certifications?

The NX3.04 carries a 5-year limited warranty and is manufactured in the United States. It is certified cTUVus, CE, FCC, and RoHS compliant, and is TAA compliant for government procurement.

Can front panel controls be locked on the NX3.04?

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.
