AtlasIED DPA804 800W Networkable 4-Channel Power Amplifier with Optional Dante Network Audio

The AtlasIED DPA804 amplifier offers powerful networkable audio performance designed for versatile commercial applications. This DSP-controlled 4-channel amplifier is configurable in multiple modes including 4-channel low impedance operation at 4Ω or 8Ω, or 2-channel 70.7V/100V operation for distributed paging and background music systems. Factory defaulted as a 2-channel 70.7V amplifier, the DPA804 can be reconfigured for various amplification needs, including mixed low and high impedance outputs, providing system designers with maximum flexibility.

Equipped with four balanced line inputs and an accessory slot for an optional DPA-DAC4 4-channel Dante™ receiver card or DPA-AMIX input card (2 mic/line and 2 AUX), the DPA804 supports up to eight inputs, all mixable and routable to any amplifier channel. Advanced DSP features such as level controls, EQ, limiters, high & low pass filters, and delay allow precise tuning for any environment. Remote control options include front panel potentiometers, onboard web GUI, or wired remote level control, with mute functions triggered by audio or contact closure. The DPA Site Manager software facilitates network discovery, fault reporting, and remote activation, streamlining system management.
