The AtlasIED HPA602 is a 2-channel commercial power amplifier delivering 300 watts per channel for low-impedance and constant-voltage loudspeaker systems. Each channel supports 4Ω, 8Ω, 70.7V, and 100V operation, allowing the amplifier to be used in commercial distributed audio, paging, background music, and professional sound reinforcement systems.

The HPA602 uses Generation II Class D output topology to provide high-output power from a compact 2RU chassis. Balanced Phoenix-style inputs, front-panel level controls, remote turn-on capability, and an optional Dante interface make it suitable for both standalone and networked commercial audio installations.

Built-in protection includes short-circuit, thermal, and DC offset protection, while a variable-speed cooling fan and thermal-management design help maintain reliable operation under demanding loads.

300 Watts Per Channel

The AtlasIED HPA602 provides two independent 300-watt amplifier channels.

Each channel can operate with:

• 4Ω loudspeaker loads
• 8Ω loudspeaker loads
• 70.7V distributed speaker systems
• 100V distributed speaker systems

This allows the same amplifier platform to be used with conventional low-impedance loudspeakers or constant-voltage commercial speaker systems.

70V and 100V Distributed Audio

With native 70.7V and 100V output capability, the HPA602 can directly power compatible constant-voltage loudspeaker systems.

This makes it particularly useful for installations with multiple ceiling, surface-mount, horn, or paging loudspeakers distributed throughout a facility.

Applications include background music, paging, educational facilities, houses of worship, hospitality, retail, corporate facilities, and other commercial audio systems.

Low-Impedance 4Ω and 8Ω Operation

The HPA602 isn't limited to distributed 70V/100V systems. Its support for 4-ohm and 8-ohm loads allows it to power compatible conventional loudspeakers for sound reinforcement and other professional audio applications.

With 300 watts available per channel, installers can select the appropriate loudspeaker configuration for each application without requiring a separate amplifier model for low-impedance and constant-voltage systems.

Generation II Class D Amplification

The HPA602 incorporates AtlasIED's Generation II Class D output topology, combining efficient amplifier operation with the audio performance required for commercial and professional sound systems.

Its compact 2RU chassis measures only 9.3 inches deep and weighs 14.8 lbs, making it useful where rack space and equipment depth are important considerations.

Optional Dante Network Audio

A rear-panel accessory slot allows the HPA602 to accept a compatible optional Dante digital audio interface card.

This gives system designers the ability to integrate the amplifier into Dante-based network audio installations when required while retaining conventional balanced analog inputs for standard installations.

Because the Dante interface is optional, I would make that very clear on the product page so customers don't assume Dante is included with the standard HPA602.

Balanced Audio Inputs and Level Controls

Balanced inputs use Phoenix-style terminal block connectors for integration with commercial audio processors, mixers, and system controllers.

Front-panel stepped level controls allow individual channel adjustment and include security covers to help prevent unauthorized changes after the system has been commissioned.

Amplifier Protection and Cooling

The AtlasIED HPA602 incorporates protection for:

• Short-circuit conditions
• Excessive temperature
• DC offset

A variable-speed cooling fan provides active thermal management based on amplifier operating conditions.

Energy-Efficient Operation

The HPA602 uses a universal AC power supply compatible with 100–240V AC mains.

The amplifier is also specified for approximately 1 watt of standby power, reducing power consumption when the system is not actively operating.

AtlasIED HPA602 Power Output

I like separating this from the general specification table. 2 × 300W at 4Ω, 8Ω, 70.7V, and 100V is probably the most important technical information on the entire page.

Why Choose the AtlasIED HPA602?

The HPA602's biggest advantage is its ability to provide 2 × 300 watts into several commonly used professional loudspeaker configurations from one amplifier platform.

Supporting 4Ω, 8Ω, 70.7V, and 100V operation makes the HPA602 suitable for both conventional loudspeakers and commercial constant-voltage systems. Its optional Dante interface also allows the amplifier to be incorporated into networked audio installations when required.
