Atlas Sound DNA2404DL Series UL-1711 Listed 70.7-Volt 4-Channel Amplifier with Dante™ Network Audio

Product Overview

The AtlasIED DNA2404DL is a UL-1711 listed Dante network amplifier delivering four channels of 600 watts at 70.7 volts for life-safety paging and mass notification systems. Designed as part of the IED GLOBALCOM communications platform, this 70V 4-channel power amplifier lets system designers add a few audio zones where a full 16-zone T9160 amplifier frame is not required. Integrators specify it for commercial paging amplifier installations in airports, transit facilities, government buildings, and campuses where supervised, fire-safety-listed amplification is mandatory.

Product Description

The DNA2404DL accepts Audinate's Dante digital audio input and provides four channels of Class D amplification rated at 600 watts each into 70.7-volt transformer-distributed speaker lines (8 ohms rated load). Input routing, EQ, delay, and output levels are configured over the network using a stand-alone GLOBALCOM configuration utility or the GLOBALCOM System Management Center, and the amplifier also works with third-party Dante devices for broader commercial AV integration.

The internal amplifier cards are dual-channel Class D designs with an integral switching-mode power supply, eliminating heavy output transformers while remaining stable into all load conditions from 0 to 360 degrees of phase angle. Each card delivers 34 dB of gain from analog input to speaker output, with attenuation handled ahead of the power stage by DSP controls in software. Per channel, integrators get a 7-band parametric EQ, high-pass and low-pass filters, and up to 40 ms of signal delay for zone time alignment.

Supervision is central to this amplifier's role in life-safety audio. Built-in automatic loudspeaker line testing detects ground faults, breaks, and changes in speaker loads, while LED indicators report power, audio signal, and fault status on the front panel. A Form C relay signals fault conditions to external monitoring, and full fault reports and amplifier status are available over Ethernet via standard SNMP — practical for IT and facilities teams monitoring distributed equipment rooms. Dual-redundant Ethernet ports protect the Dante audio network connection against a single link failure. Inputs for up to eight 540S ambient noise sensors (two per output channel) enable continuous real-time ambient analysis with automatic output level control, keeping pages intelligible as crowd noise changes. The unit operates from 120 VAC in a compact 2RU-height chassis. Find compatible controllers and endpoints in the AtlasIED collection at Creation Networks.

Key Features

• UL-1711 Fire Safety Listing — Safety listed to the UL 1711 standard, qualifying the amplifier for life-safety and emergency communication system installation.
• Four 600-Watt Output Channels — Delivers 600 watts per channel at 70.7 volts for transformer-distributed loudspeaker zones.
• Dante Network Audio Input — Accepts Dante digital audio and is compatible with GLOBALCOM systems and third-party Dante devices.
• Dual-Redundant Ethernet Ports — Maintains the network audio connection if one link fails, protecting critical paging paths.
• Automatic Loudspeaker Line Testing — Detects ground faults, line breaks, and load changes so failures are caught before an emergency page is missed.
• SNMP Status Reporting — Publishes fault reports and amplifier status over Ethernet using standard SNMP for centralized monitoring.
• Per-Channel DSP — Provides 7-band parametric EQ, high-pass and low-pass filters, and up to 40 ms of delay on each channel.
• Ambient Noise Compensation — Supports two 540S ambient noise sensors per channel (eight total) for continuous, automatic output level control.
• Efficient Class D Design — Switching-mode amplification and power supply improve efficiency and reliability while reducing weight and operating cost.
• Fault Relay Output — A Form C relay signals fault conditions to external supervision and monitoring systems.

Typical Applications

• Government spaces and public buildings with supervised paging requirements
• Auditoriums and large assembly venues
• Commercial meeting spaces and corporate campuses
• Multi-purpose rooms on transit and education campuses
• Training rooms and all-hands rooms tied into facility-wide notification
• Broadcast studios requiring networked 70V distribution

Technical Specifications

Frequently Asked Questions

Why does the UL-1711 listing matter for this amplifier?

UL 1711 is the standard for amplifiers used in fire protective signaling systems. The listing allows the DNA2404DL to be specified in life-safety and emergency communication designs where code compliance requires listed amplification.

Does the DNA2404DL work outside of GLOBALCOM systems?

Yes. While it integrates natively with IED GLOBALCOM controllers, the Dante input is compatible with third-party Dante devices, so it can serve as a networked 70V amplifier in broader Dante audio system designs.

How are speaker lines supervised?

Built-in automatic loudspeaker line testing detects ground faults, breaks, and changes in loudspeaker loads, and faults are reported via front-panel LEDs, a Form C relay, and SNMP over Ethernet.

How does ambient noise compensation work?

Each of the four output channels accepts two 540S ambient noise sensors. The amplifier continuously measures zone noise and automatically adjusts output level in real time so announcements stay intelligible.

How are EQ, delay, and levels configured?

All routing and DSP settings — 7-band parametric EQ, filters, delay, and output levels — are configured over the network with the stand-alone GLOBALCOM configuration utility or the GLOBALCOM System Management Center.

What rack space and power does it require?

The chassis is 3.5 inches high (2RU) by 19 inches wide with rack ears, 17 inches deep, weighs 19.2 lb, and operates from a 110–120 VAC source.

Can Creation Networks help with system design and quotes?

Yes. Creation Networks supports commercial AV integrators, facilities teams, and procurement with AtlasIED system design assistance, project pricing, and volume quotes.
