The DNA2404DL amplifier from AtlasIED features Audinate's Dante™ digital audio input and four (4) channels of 600 watt amplification and 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 DNA2404DL 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 Class-D (switching mode) dual channel amplifiers deliver 600W per channel into the rated loads (70.7 Volts into 8Ω). Class D operation, combined with an integral switching mode power supply. They provide 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 DNA2404DL 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 DNA2404DL provides 600 watts per channel for 70.7 volt transformer-distributed speaker systems and requires a 120 VAC power source.
