400-watt networkable 4-channel power amplifier with optional Dante™ network audio

The AtlasIED DPA404 amplifier features a combination of flexibility, performance, and control to provide high-value features for applications that require more than just great sound. The network-enabled DPA404 is a DSP-controlled, four-channel amplifier that can be configured in three different amplification arrangements to meet a wide range of installation design requirements.

The DPA404 can be used right out of the box in its factory default configuration as a traditional four-channel 70.7V commercial power amplifier requiring no programming, special setup, or network connectivity. However, the DPA404 can be configured in four-channel mode with load impedances of 4 Ω or 8 Ω for two stereo zones. Many system designs require both high and low impedance amplification. The DPA404 can be configured for a 70.7V/100V PA/BACK system on two channels and the other two channels can be used for 4Ω/8Ω foreground stereo applications.

The DPA404 comes standard with four balanced line inputs and an accessory slot for an optional DPA-DAC4 four-channel Dante™ receiver card or DPA-AMIX (2) mic/line and (2) AUX input card, for a total of eight inputs. All inputs can be mixed and routed to any of the amplifier's four channels. All amplifier channels feature a variety of DSP tools including level controls, EQs, limiters, high- and low-pass filters, and delay to provide flexibility for a variety of applications.

The output level can be assigned to the front panel potentiometers or the integrated GUI. Wired remote level controls can be configured to allow easy control by the end user. Each unit also features GUI-based input and output level metering along with assignable mute functions that are activated by an audio signal or contact closure. Access to the DSP settings is done through a computer, tablet, or mobile device using a web browser. All settings can be password protected.
