ASHLY NXE4004BD amplifier plus OPDante and OPDAC4 Option Cards

Product Overview

The Ashly NXE4004BD is a four-channel networkable power amplifier delivering 400 watts per channel across all load configurations, factory-equipped with both a Dante option card (OPDante) and an analog output expansion card (OPDAC4). Designed for commercial AV installations where Dante audio networking and analog output distribution are both required, the NXE4004BD suits corporate boardrooms, multi-zone conference facilities, houses of worship, and distributed audio systems in commercial spaces. Unlike the NXP series, the NXE4004BD does not include onboard DSP — signal processing is handled externally — making it a focused network amplifier platform for integrators who manage DSP through a separate processor or Dante-enabled DSP device. The consistent 400W/ch output across 70V, 100V, and 2/4/8 ohm loads simplifies system design for mixed-speaker installations.

Product Description

The Ashly NXE4004BD Dante audio commercial amplifier integrates network audio transport with four-channel multi-mode amplification and analog output expansion in a single rack-mount chassis. The factory-installed OPDante card provides native Dante audio over standard Ethernet, enabling lossless digital audio routing from any Dante-enabled source on the network. The factory-installed OPDAC4 card adds four analog output channels, providing a parallel analog output path for feeding additional equipment — such as a hearing loop driver, recording system, or analog zone mixer — without a separate DA converter in the signal chain. Each of the four amplifier output channels is independently configurable for 70V or 100V constant-voltage or low-impedance (2, 4, or 8 ohm) operation via rear panel DIP switches, giving system integrators the flexibility to serve mixed-load speaker inventories across zones from a single unit. The NXE series includes Ethernet-based remote control via Ashly's network management software, plus an event scheduler for automating preset recalls, standby transitions, and power-on delays based on programmed daily schedules. This makes the NXE4004BD practical for corporate environments where the amplifier system needs to follow a predictable operational schedule without manual intervention. The Ashly EMS (Energy Management System) provides automatic sleep mode drawing less than 1 watt during idle periods. Neutrik connectors throughout — Combo XLR/TRS inputs, speakON speaker outputs, and powerCON AC mains — ensure reliable permanent-installation terminations. The NXE4004BD is TAA compliant, RoHS and cTUVus certified, and manufactured in the United States with a 5-year limited warranty.

Key Features

• Factory-Installed Dante Option Card (OPDante) — Native Dante audio networking over Ethernet for lossless digital audio routing from any Dante source device.
• Factory-Installed OPDAC4 Analog Output Card — Four additional analog output channels for parallel signal distribution to hearing loops, recorders, or analog zone mixers.
• 400 W/Ch Across All Loads — Consistent 400W per channel at 70V, 100V, 8 ohm, 4 ohm, and 2 ohm for straightforward multi-zone capacity planning.
• 4-Channel Multi-Mode Output — Each channel independently configurable for constant-voltage (70V/100V) or low-impedance (2/4/8 ohm) via rear DIP switches.
• No Onboard DSP — Signal processing is handled externally; the NXE4004BD is a network amplifier platform designed to work alongside dedicated DSP devices.
• Ethernet Network Control — Remote control, monitoring, and preset management over Ethernet.
• Event Scheduler — Automated preset recalls, standby, and power-on transitions on programmable daily schedules.
• Ashly EMS Energy Management — Automatic sleep mode draws less than 1 watt; defeatable.
• Neutrik Connectors Throughout — Combo XLR/TRS inputs, speakON outputs, and powerCON AC mains for permanent installation reliability.
• 5-Year Limited Warranty — Manufactured in the United States; TAA compliant, RoHS and cTUVus certified.

Frequently Asked Questions

What is the OPDAC4 card in the NXE4004BD?

The OPDAC4 is a factory-installed analog output expansion card providing four additional analog line-level outputs. These can be used to feed parallel signal paths — such as a hearing loop driver, zone mixer, or recording system — directly from the amplifier without a separate DA converter.

Does the NXE4004BD include DSP?

No. The NXE4004BD is part of the NXE (networkable) series, which does not include onboard Protea DSP. DSP functions are handled by an external processor. For an integrated DSP solution, consider the NXP series amplifiers.

Does the NXE4004BD support Dante audio networking?

Yes. The NXE4004BD ships with a factory-installed OPDante card for native Dante audio over standard Ethernet, configured using Audinate's Dante Controller software.

Can the NXE4004BD drive 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.

What AV control systems is the NXE4004BD compatible with?

The NXE4004BD supports Ethernet-based remote control and monitoring, serial control via Ashly remote devices, and third-party RS-232 control with the optional INA-1 converter.

What is the warranty on the NXE4004BD?

The NXE4004BD carries a 5-year limited warranty and is manufactured in the United States. It is TAA compliant and certified RoHS and cTUVus.
