AtlasIED DNA2404 Series 4-Channel 2400W Digital Network Power Amplifier

The AtlasIED DNA2404 Series represents a highly advanced line of 4-channel networked power amplifiers, delivering 600 watts per channel (2400 W total) with transformer-isolated outputs at either 70.7-Volt or 100-Volt. Designed for robust integration within GLOBALCOM® and third-party audio systems, each model in the series offers precision Class D amplification, built-in DSP for EQ and filtering, ambient noise compensation, and redundant Ethernet ports. The amplifiers support CobraNet® or Dante™ digital audio transmission depending on the model, making them ideal for facilities requiring paging, background music, and sound masking across large distributed systems.

Equipped with support for real-time ambient noise analysis, the DNA2404 series automatically adjusts output levels to maintain clarity across all channels. Enhanced with SNMP monitoring, output supervision, and fault reporting, the amplifiers provide a scalable, supervised solution for mission-critical AV environments. All models are rack-mountable (2RU), made in the USA, and BAA compliant. Select from four model variations based on voltage and digital audio protocol requirements.
