The DNA2404CH amplifier from AtlasIED, featuring CobraNet® digital audio input and four channels of 600 watt amplification, is an integral part of the IED 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 internal Class-D (switching mode) dual channel amplifiers deliver 600W per channel into the rated loads (100-Volts into 16Ω). They impart higher efficiency, increased reliability, improved performance, and lower operating cost. The amplifier card has 34dB of gain from its analog input to the speaker output.

Attenuation is handled ahead of the power amplifier by DSP controls through software. Inputs are provided for connecting up to eight (8) 540S ambient noise sensors (2 sensors for each output channel). This allows the output of each channel to be automatically adjusted in real time based on the measured ambient noise level in the zone.

The DNA2404CH features LED indicators for power, audio signals and fault status. A Form C relay is also included to indicate that a fault is present. The DNA2404CH provides 600 watts per channel for 100-volt transformer-distributed speaker systems and operates from a 220 VAC power source.
