The AtlasIED HPA1302 is a high-efficiency, two-channel professional power amplifier designed for demanding commercial audio installations and sound reinforcement applications. Delivering 650 watts per channel, the HPA1302 supports 70.7V and 100V distributed audio systems as well as 4-ohm and 8-ohm speaker loads, providing flexibility for a wide range of professional sound systems.
Built with AtlasIED's Generation II Class D amplifier technology, the HPA1302 combines efficient power delivery with high-quality audio reproduction. Its compact, lightweight design makes it an excellent choice for commercial paging systems, background music installations, auditoriums, conference centers, and large distributed speaker networks.
The amplifier features balanced audio inputs, front-panel detented level controls with a security cover, remote turn-on capability, and fault reporting for professional system integration. A rear-panel accessory card slot also supports an optional Dante digital audio interface, allowing the amplifier to be incorporated into compatible networked audio systems.
With a universal auto-sensing switch-mode power supply, efficient thermal management, and low standby power consumption, the HPA1302 delivers dependable performance while helping reduce energy consumption in commercial installations.
650 Watts Per Channel for Commercial Audio Systems
The AtlasIED HPA1302 delivers 2 × 650 watts across its supported output configurations, making it suitable for high-power distributed audio and professional sound reinforcement applications.
Supported output configurations include:
-
70.7V distributed audio: 650 watts per channel
-
100V distributed audio: 650 watts per channel
-
8-ohm speaker loads: 650 watts per channel
-
4-ohm speaker loads: 650 watts per channel
This flexibility allows system designers to use the HPA1302 in installations requiring constant-voltage speaker distribution or conventional low-impedance loudspeaker connections.
For commercial facilities with multiple speakers, the amplifier provides substantial power for appropriately designed distributed audio systems.
In low-impedance applications, the HPA1302 can power compatible professional loudspeakers requiring higher amplifier output.
Generation II Class D Amplification
The HPA1302 incorporates Generation II Class D output technology, designed to provide efficient amplification without sacrificing audio performance.
This amplifier design offers the energy efficiency associated with Class D technology while delivering the sound quality expected from professional audio equipment.
With a specified 20 Hz–20 kHz frequency response and less than 0.05% total harmonic distortion, the HPA1302 supports clean audio reproduction for music and speech applications.
Its efficient design also helps reduce unnecessary power consumption in commercial systems that operate for extended periods.
Optional Dante Digital Audio Connectivity
The AtlasIED HPA1302 includes a rear-panel accessory card slot designed to accommodate an optional Dante digital audio interface.
This capability allows the amplifier to be integrated into compatible networked audio systems when equipped with the appropriate accessory card.
Dante connectivity can simplify audio distribution in larger facilities by allowing compatible audio devices to communicate over an Ethernet-based network.
This makes the HPA1302 a flexible option for modern commercial audio installations that may require networked audio integration.
Note: Dante connectivity requires a compatible optional accessory card and is not included as a standard built-in feature.
Professional Controls and System Integration
The HPA1302 includes several features designed for professional installation and system management.
Balanced Audio Inputs
Balanced inputs help reduce unwanted noise in professional audio installations, particularly where longer signal cable runs are required.
Front-Panel Level Controls
Detented front-panel controls allow installers to adjust amplifier output levels with repeatable settings.
A security cover helps prevent unauthorized or accidental adjustments after system setup.
Remote Turn-On Capability
Remote power control allows the amplifier to be integrated into compatible centralized equipment management systems.
Fault Reporting
Fault reporting provides system status information that can assist with monitoring and troubleshooting.
Together, these features make the HPA1302 suitable for commercial installations where dependable operation and controlled system access are important.
Efficient Cooling and Universal Power Supply
The AtlasIED HPA1302 features a universal auto-sensing switch-mode power supply designed to accommodate varying electrical supply conditions.
Its thermal management system uses a low-resistance, direct-coupled heat transfer design to help maintain operating temperatures across different loads and output levels.
A variable-speed cooling fan provides additional thermal management during operation.
The amplifier also features low standby power consumption of approximately 1 watt, supporting energy-efficient commercial audio installations.
Compact 2RU Rackmount Design
Despite its high output power, the HPA1302 is designed for efficient rack installation.
The amplifier occupies 2 rack units and measures approximately 19 inches wide, 3.5 inches high, and 9.3 inches deep.
With a weight of approximately 15.4 pounds, the HPA1302 provides substantial amplifier output in a relatively lightweight chassis.
Its compact depth can be especially useful in commercial equipment racks where available space is limited.
