2400-Watt Networkable Multi-Channel Power Amplifier

The AtlasIED DPA2402 is a 2400-watt networkable multi-channel power amplifier developed for paging and background-audio systems with 70V or 100V capabilities. Its two channels deliver 2 x 1200 watts at 70.7V, while Dante audio capability, balanced inputs, DSP filtering, and universal voltage compatibility support integration into networked audio installations.

Ideal Use Cases

The DPA2402 is suited to paging and background-audio applications that require substantial output from a rack-mounted amplifier. Its rated output of 2 x 1200 watts at 70.7V provides the full 2400-watt capacity across two channels. Support for 70V and 100V systems makes it appropriate for compatible distributed-audio infrastructure. The networkable design and Dante audio capability also address installations in which audio is transported as part of a networked system. A standard 19-inch width and 2U chassis format allow the amplifier to be incorporated into equipment racks without requiring a proprietary enclosure.

Why Choose This Model

This model combines high output with clearly documented input and signal-performance specifications. Its Class AB switching hybrid BASH amplifier topology is paired with balanced 750mV, 0dBu input sensitivity and a balanced 40-kilohm input impedance. Maximum input signal is specified as +14dBu for Inputs 1-4 and +7dBu for Inputs 5-8 with Dante. These defined levels help system designers evaluate compatibility with connected audio components. The DPA2402 also supports both common voltage ranges through automatic switchover, reducing the need to select a separate regional voltage version.

Installation and Integration

The amplifier measures 19 inches wide, 3.47 inches high, and 14.5 inches deep, equivalent to 483 x 89 x 368mm. It occupies two rack units and weighs 20.8 pounds, or 9.53kg. Power compatibility covers 110-120V and 220-240V at 50/60Hz, with automatic switchover and universal voltage compatibility listed in the supplied specifications. Idle power is rated at 26W. During system planning, installers can use the specified balanced input sensitivity, input impedance, and maximum input levels to coordinate the amplifier with the rest of the signal path. Its rack depth and weight should also be considered when selecting and arranging the equipment rack.

Performance Highlights

Power output is rated at 2 x 1200 watts at 70.7V. Frequency response is specified as 3dB from 20Hz to 20kHz when the DSP filters are set to flat. Total harmonic distortion is rated at 1% at rated output. The listed signal-to-noise ratio is 100dB below rated output with A-weighting, while crosstalk is specified at 73dB at 1kHz. Together, these figures provide concrete reference points for output capacity, frequency coverage, channel separation, and noise performance. The inclusion of a documented flat DSP-filter setting also helps identify the conditions under which the frequency-response specification applies.

What Makes It Different

The defining feature set is the combination of 2400 watts of total rated output, two 1200-watt channels, 70V and 100V system capability, networkable operation, and Dante audio capability in a 2U chassis. The Class AB switching hybrid BASH topology distinguishes the amplifier architecture, while the balanced input specifications provide exact integration requirements. Universal voltage support with automatic switchover adds flexibility when matching the unit to an available power service. AtlasIED covers the amplifier with a warranty period of 36 months from the date of purchase.

Final Assessment

The AtlasIED DPA2402 is a focused choice for a paging or background-audio system requiring two high-output channels and compatibility with 70V or 100V infrastructure. Its 2 x 1200-watt output at 70.7V, Dante audio capability, DSP-referenced frequency response, balanced inputs, universal voltage operation, and 2U rack dimensions are all specified for system planning. Before installation, confirm that its output format, input levels, chassis dimensions, power requirements, and network-audio capabilities align with the associated equipment and system design.
