Atlas Sound DNA2404CH – 100V 4-Channel Amplifier with CobraNet Network Audio

What is the Atlas Sound DNA2404CH?

The DNA2404CH is a standalone 4-channel, 2400-watt total networked power amplifier with CobraNet digital audio input, built for 100V transformer-distributed speaker systems on 220 VAC power. It's an integral part of the IED GLOBALCOM Communications System, sized for adding a few audio zones where a full 16-zone T9160 frame isn't needed.

How does the Atlas Sound DNA2404CH work?

The DNA2404CH is controlled entirely over the network for input routing, EQ, delay, and output levels via the GLOBALCOM configuration utility or System Management Center. Each of the four 600W channels includes a 7-band parametric EQ plus high-pass and low-pass filters, and inputs are provided for up to eight 540S ambient noise sensors (two per channel) for continuous, real-time ambient noise analysis and automatic output level control — keeping paging and announcements intelligible as room noise changes. Dual-redundant Ethernet ports support network resilience, LED indicators show power, audio, and fault status per channel, and a Form C relay reports fault conditions to the supervision system. Built-in automatic loudspeaker line testing detects ground faults, breaks, and load changes, with fault reports and amplifier status available over Ethernet via standard SNMP.

What are the key features of the Atlas Sound DNA2404CH?

• 2400W total, 4 x 600W channels — 100V output for large distributed speaker zones.
• CobraNet network audio — Compatible with IED GLOBALCOM systems and third-party CobraNet devices.
• Automatic ambient noise compensation — Two ambient sensor inputs per channel for real-time level adjustment.
• Automatic speaker line testing — Detects ground faults, breaks, and load changes without manual inspection.
• Dual-redundant Ethernet — Network resilience for mission-critical paging.
• SNMP fault reporting — Amplifier status available over standard network protocols.

Where is the Atlas Sound DNA2404CH typically used?

• Government space
• Multi-purpose room
• Auditorium

Frequently Asked Questions

Is this compatible with a full T9160-based GLOBALCOM system?
Yes. It's designed to add a few audio zones to an existing GLOBALCOM deployment where a full 16-zone T9160 frame isn't needed.

Does it require ambient noise sensors?
No, they're optional; up to eight 540S sensors (sold separately) enable automatic level adjustment based on real-time ambient noise.

What's the difference between this and the DNA2404DH?
Same 100V, 2400W, 220VAC specification; this model uses CobraNet network audio, the DH model uses Dante.

What warranty applies?
36 months from date of purchase.
