ASHLY NXP1.54D Amplifier plus OPDante Option Card

Product Overview

The Ashly NXP1.54D is a four-channel networkable power amplifier with integrated Protea DSP and a factory-installed Dante option card, purpose-built for demanding commercial AV installations. Delivering 1,500 watts per channel at 70V and 1,250 watts per channel at 8 ohms, this Dante-enabled commercial power amplifier handles large-scale distributed audio in performance venues, houses of worship, convention centers, and multi-zone commercial installations. The NXP1.54D combines Class-D efficiency with 32-bit SHARC DSP processing, giving system integrators full signal chain control from a single rack-mount unit. Its multi-mode output configuration supports both constant-voltage 70V/100V and low-impedance 2, 4, and 8 ohm loads on each channel independently.

Product Description

The Ashly NXP1.54D networkable amplifier with DSP is the top-tier model in the NXP series, integrating Dante audio networking directly into a 4-channel rack-mount chassis. In a commercial installation, this means audio routing, DSP configuration, and amplifier control all pass through a standard Ethernet infrastructure — no separate DSP processor required. The Protea DSP engine provides comprehensive signal processing including dynamics, parametric EQ, matrix mixing, crossover, delay, and metering, all configurable via Ashly's Protea NE software from any networked PC. For multi-zone 70V distribution in large venues, each of the four channels can be independently set to 70V or 100V constant-voltage mode via rear DIP switches, making it straightforward to serve multiple speaker zones from one amplifier. FIR filter support allows system integrators to load speaker manufacturer files directly, achieving precision tuning without external processors. The built-in real-time clock with event scheduler enables automated execution of preset recalls, sleep modes, and other programmed functions — particularly useful in corporate and worship environments with repeating daily schedules. The Ashly EMS (Energy Management System) provides automatic sleep mode drawing less than 1 watt of idle power, supporting sustainability requirements in commercial facilities. Aux preamp line outputs allow the NXP1.54D to drive additional amplifiers downstream, making it a natural hub amplifier in large distributed systems. The Ashly Remote iPad app gives operators wireless control of DSP functions including gain, mute, matrix, and PEQ adjustments, without requiring a laptop at the rack. Fault condition logic outputs per channel enable remote monitoring and integration with building management or control systems. All connectors are Neutrik — Combo XLR/TRS and Euroblock inputs, speakON speaker outputs, and powerCON AC mains — ensuring secure, professional-grade connections in permanent installations.

Technical Specifications

Frequently Asked Questions

What AV control systems is the NXP1.54D compatible with?

The NXP1.54D supports Ethernet control via Ashly's Protea NE software, serial control via Ashly WR-5 and RD-8C programmable remotes, and third-party RS-232 control using the optional INA-1 converter. A Q-SYS plugin for Protea is available for integration with Q-SYS control platforms.

Does the NXP1.54D support Dante audio networking?

Yes. The NXP1.54D ships with a factory-installed OPDante option card, providing full Dante audio over standard Ethernet. It can be configured using Audinate's Dante Controller software alongside Ashly's Protea NE software.

Can the NXP1.54D drive both 70V and low-impedance speakers simultaneously?

Yes. Each of the four channels is independently configurable for 70V, 100V constant-voltage or 2, 4, or 8 ohm low-impedance operation via rear panel DIP switches, allowing mixed-load deployments across a single amplifier.

How is the NXP1.54D programmed and monitored remotely?

Protea NE software provides full remote control and monitoring over Ethernet, including DSP parameter adjustment, preset management, and fault monitoring. The free Ashly Remote iPad app provides wireless control of common DSP functions over the same network.

What is the NXP1.54D's warranty and where is it manufactured?

The NXP1.54D carries a 5-year limited warranty and is manufactured by Ashly Audio in Webster, New York, USA. It is TAA compliant and certified RoHS and cTUVus.

Does the NXP1.54D have an event scheduler?

Yes. A built-in real-time clock with event scheduler allows automated execution of preset recalls, standby mode, and power-on delay on a time-based schedule, programmed via Ashly's PneS software and stored in the amplifier's memory.

What input and output connectors does the NXP1.54D use?

Inputs use Neutrik Combo XLR/TRS jacks plus Euroblock connectors. Speaker outputs use Neutrik speakON twist-locking connectors. The AC mains connection uses a Neutrik powerCON detachable connector — all appropriate for permanent commercial installation.
