ASHLY NXP4004D Amplifier plus OPDante Option Card

Product Overview

The Ashly NXP4004D is a four-channel networkable power amplifier with integrated Protea DSP and a factory-installed Dante option card, delivering 400 watts per channel across all load configurations — 70V, 100V constant-voltage, and 2, 4, or 8 ohm low-impedance. This Dante-enabled commercial power amplifier is designed for distributed audio installations in corporate environments, houses of worship, conference rooms, and commercial spaces where network-based audio routing and onboard signal processing are required in a compact four-channel rack-mount chassis. The NXP4004D's uniform 400W/ch output across all impedances makes it particularly well-suited for installations with mixed speaker loads across multiple zones, removing complexity from zone capacity planning. The complete Protea DSP feature set — including event scheduling, FIR filter support, and wireless iPad control — is available in a cost-effective four-channel platform.

Product Description

The Ashly NXP4004D networkable amplifier with DSP commercial install integrates Dante audio networking, Protea DSP processing, and four-channel multi-mode amplification in a single rack-mount unit. The factory-installed OPDante option card provides native Dante audio routing over standard Ethernet, removing the need for dedicated analog audio runs from source equipment to the amplifier. Protea DSP delivers comprehensive signal processing including dynamics, parametric EQ, crossover, matrix mixing, delay, metering, and FIR filter support, all accessible remotely via Ashly's Protea NE software. Each of the four output 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, making the NXP4004D adaptable to installations with varied speaker configurations across zones. The 400W/ch output across all load types is well-matched for boardroom AV systems, multi-zone commercial meeting spaces, training rooms, and similar commercial installations where moderate per-zone output is required. A built-in real-time clock with event scheduler automates preset recalls, standby transitions, and power-on delays on programmed daily schedules — beneficial in corporate environments with predictable daily usage patterns. The Ashly Remote iPad app provides wireless control of DSP parameters including gain, mute, matrix routing, and PEQ over the same Ethernet network. Aux preamp line outputs allow the NXP4004D to feed additional amplifiers for system expansion. The Ashly EMS (Energy Management System) provides automatic sleep mode drawing less than 1 watt during idle periods. All connections use Neutrik connectors — Combo XLR/TRS inputs, speakON speaker outputs, and powerCON AC mains — for professional permanent-installation reliability.

Technical Specifications

Frequently Asked Questions

What AV control systems is the NXP4004D compatible with?

The NXP4004D supports Ethernet control via Protea NE software, serial control via Ashly WR-5 and RD-8C remotes, and third-party RS-232 control with the optional INA-1 converter. A Q-SYS plugin for Protea is available for Q-SYS platform integration.

Does the NXP4004D support Dante audio networking?

Yes. The NXP4004D ships with a factory-installed OPDante option card for native Dante audio over standard Ethernet, configured using Audinate's Dante Controller alongside Ashly's Protea NE software.

Why is the output 400W/ch across all impedances?

The NXP4004D is designed for a consistent 400W/ch output regardless of load impedance (2, 4, 8 ohm, 70V, or 100V), simplifying system design for multi-zone installations with mixed speaker loads.

Can the NXP4004D be controlled wirelessly?

Yes. The free Ashly Remote iPad app provides wireless network control of DSP functions including gain, mute, matrix routing, A/B source select, PEQ adjustments, and metering.

What is the NXP4004D warranty?

The NXP4004D carries a 5-year limited warranty and is manufactured in Webster, New York, USA. It is TAA compliant and certified RoHS and cTUVus.

Does the NXP4004D have automated scheduling?

Yes. A built-in real-time clock with event scheduler automates preset recalls, standby mode, and power-on delays on daily schedules, programmed via PneS software and stored in the amplifier.
