AtlasIED – DNA2404DH

The DNA2404DH amplifier is an integral part of theAtlasIED GLOBALCOM® Communications System, allowing a few audio zones to be added where necessary when a full 16-zone T9160 amplifier frame is not required.
The DNA2404DH amplifier is an integral part of theAtlasIED GLOBALCOM® Communications System, allowing a few audio zones to be added where necessary when a full 16-zone T9160 amplifier frame is not required. The amplifier features Audinate’s Dante™ digital audio input and four channels of 600 watt amplification. The DNA2404DH is controlled with network commands for selecting input routing and configuring EQ, delay and output levels. Amplifiers may be controlled by a stand-alone GLOBALCOM® configuration utility or through the GLOBALCOM System Management Center.The internal amplifier cards are Class D (switching mode) dual channel 600W amplifiers into the rated loads (100-Volts into 16Ω). Class D operation, combined with an integral switching mode power supply, offers many advantages, and the uniqueAtlasIED design makes full use of these benefits. They include higher efficiency, increased reliability, improved performance, and lower operating cost. Switching mode operation combined with high voltage power MOSFET devices make it possible to eliminate the heavy, costly, bulky transformers.AtlasIED’s design is stable under all load conditions (phase angles of 0 to 360 degrees). The amplifier card has 34dB of gain from its analog input to the loudspeaker output. Attenuation is handled ahead of the power amplifier by DSP controls through software.
