Dante Enabled Accessory Cord for use with HPA Amplifiers

Ideal Use Cases

The AtlasIED HPA-DAC2 is a Dante™ network audio expansion card designed to work with HPA Series 2-channel amplifiers. It is intended for HPA amplifier systems that require the network-audio expansion identified for this accessory. The RJ-45 connector provides the specified connection interface, while the published frequency response, distortion, gain-reference, and output-level values support informed system planning. Compatibility is specifically stated for HPA Series 2-channel amplifiers, so the HPA-DAC2 should be selected for that product family rather than treated as a universal expansion card for unrelated amplifier platforms. Its dimensions and low weight also make its physical requirements easy to evaluate before installation.

Why Choose This Model

The HPA-DAC2 combines Dante™ network audio expansion with clearly documented audio specifications. Frequency response is rated from 20 Hz to 20 kHz within ±1 dB, covering the stated audio range with a defined tolerance. Total harmonic distortion is specified at 0.06% at 1 kHz, and the maximum output level is 7 dBu. Gain controls provide two PCB-shunt-selectable settings: 0 dBFS equals 20 dBu or 0 dBFS equals 10 dBu. These two documented reference options provide a specific configuration choice during system setup. Rather than presenting an unspecified network interface, this model identifies its connector, level references, frequency response, maximum output level, and distortion measurement.

Installation and Integration

This accessory card is designed to operate in conjunction with compatible HPA Series 2-channel amplifiers. Network connectivity is provided through an RJ-45 connector. The PCB shunt should be configured for the required documented gain reference, with available selections of 0 dBFS equals 20 dBu and 0 dBFS equals 10 dBu. The card measures 0.97 inches high by 2.7 inches wide by 2.5 inches deep, equivalent to 2.46 by 6.8 by 6.3 centimeters. It weighs 2.6 ounces, or 0.07 kilograms. These measurements allow the accessory’s physical envelope and weight to be considered alongside amplifier compatibility, connection requirements, and gain-reference selection during integration planning.

Performance Highlights

The HPA-DAC2 has a specified frequency response of 20 Hz to 20 kHz within ±1 dB. Its total harmonic distortion specification is 0.06% at 1 kHz, providing a defined measurement for evaluating audio performance at that test frequency. Maximum output level is listed as 7 dBu. The selectable gain references give installers two published digital full-scale relationships, selected by PCB shunt: 0 dBFS equals 20 dBu or 0 dBFS equals 10 dBu. The supplied technical data also lists a refresh rate of 20 Hz. That value is retained as a separate specification and should not be confused with the card’s 20 Hz to 20 kHz audio frequency response.

What Makes It Different

This model is purpose-defined as a Dante™ accessory card for the HPA Series 2-channel amplifier platform. Its key distinction is the combination of Dante™ network audio expansion, an RJ-45 interface, and two selectable gain-reference settings in a card measuring only 0.97 by 2.7 by 2.5 inches. The specification set also includes a 7 dBu maximum output level, 0.06% THD at 1 kHz, and a frequency response extending from 20 Hz to 20 kHz within ±1 dB. The stated warranty period is 12 months from the date of purchase, providing a clearly defined coverage duration for the accessory.

Final Assessment

The AtlasIED HPA-DAC2 is a focused expansion option for compatible HPA Series 2-channel amplifiers requiring Dante™ network audio capability. Its RJ-45 connector, selectable 0 dBFS gain references, documented 20 Hz to 20 kHz frequency response, and compact physical dimensions provide the principal information needed for product selection and integration planning. The 0.06% THD specification at 1 kHz and 7 dBu maximum output level further define its audio characteristics. For systems based on the stated HPA amplifier family, the HPA-DAC2 provides a purpose-designed Dante™ accessory card backed by a 12-month warranty from the date of purchase.
