Dante Enabled Accessory Card for Use with HPA 4 Channel Amplifiers

The AtlasIED HPA-DAC4 is a four-input Dante-enabled network audio expansion card designed specifically for use with HPA Series 4-channel amplifiers. It adds a network audio interface to a compatible amplifier through a compact accessory-card format, providing an RJ-45 connection and selectable gain settings. Its published audio specifications include a 20Hz to 20kHz frequency response, 0.06% THD at 1kHz, and a maximum output level of 7dBu.

Ideal Use Cases

The HPA-DAC4 is intended for audio systems that use an HPA Series 4-channel amplifier and require four-input Dante network audio expansion. It is a focused choice when the amplifier platform is already established and Dante connectivity is needed as an integrated accessory. Because the card is designed to work in conjunction with the specified HPA amplifiers, it is best suited to installations where compatibility with that amplifier series has been confirmed.

The four-input design makes the card relevant to systems that need to bring multiple Dante audio inputs into a compatible four-channel amplifier. It is not presented as a standalone Dante interface or a universal amplifier accessory; its stated purpose is expansion of the supported HPA platform.

Why Choose This Model

This model combines four-input Dante capability with a purpose-built HPA amplifier accessory format. The RJ-45 connector provides the card’s network connection, while its PCB-shunt-selectable gain controls support two documented reference settings: 0dBFS equals 20dBu or 0dBFS equals 10dBu. These choices allow the card’s gain configuration to be matched to the applicable system requirements using the available settings.

The HPA-DAC4 also provides clearly stated physical and performance specifications. It measures 0.97 inches high, 2.7 inches wide, and 2.5 inches deep, with metric measurements of 2.46 by 6.8 by 6.3 centimeters. At 2.6 ounces, or 0.07 kilograms, it is a compact, lightweight component for the compatible amplifier platform.

Installation and Integration

Integration centers on a compatible HPA Series 4-channel amplifier and the card’s RJ-45 connector. The product is identified as an accessory card, so it should be selected as part of an HPA amplifier configuration rather than treated as an independent network audio device. Before installation, the amplifier series and channel configuration should be checked against the stated compatibility.

The required gain reference can be selected through the PCB shunt using the documented 0dBFS-to-20dBu or 0dBFS-to-10dBu setting. The supplied source data does not specify a card-slot location, installation sequence, network configuration procedure, or firmware requirement, so those details are not assumed here.

Performance Highlights

The published frequency response spans 20Hz to 20kHz with a tolerance of plus or minus 1dB. Total harmonic distortion is specified at 0.06% at 1kHz, and the maximum output level is listed as 7dBu. A refresh rate of 20Hz is also included in the supplied technical data. Together, these figures provide concrete reference points for evaluating the card within a compatible HPA and Dante system.

The selectable gain references are an important part of the card’s performance configuration. Rather than listing a single fixed reference, the HPA-DAC4 provides the two PCB-shunt-selectable options documented for the model. This gives system designers and installers a defined choice when aligning the accessory card with the connected audio system.

What Makes It Different

The HPA-DAC4 is differentiated by its narrow, application-specific design: it is a four-input Dante accessory created for HPA Series 4-channel amplifiers. Its value comes from combining Dante network audio expansion, an RJ-45 interface, and selectable gain references in one compatible card. This dedicated relationship with the HPA platform distinguishes it from products described as standalone or broadly compatible network interfaces.

Its specification set is equally focused. The card provides the essential network connector, gain-selection options, audio performance figures, physical dimensions, weight, and a stated 12-month warranty from the date of purchase without adding unrelated functions.

Final Assessment

For an HPA Series 4-channel amplifier requiring four-input Dante network audio expansion, the AtlasIED HPA-DAC4 offers a purpose-designed solution with an RJ-45 connection and PCB-shunt-selectable gain references. Its 20Hz to 20kHz frequency response, 0.06% THD at 1kHz, 7dBu maximum output level, compact dimensions, and 2.6-ounce weight define its role clearly. The product includes a 12-month warranty measured from the date of purchase.
