Atlas Sound HPA602 Dual-Channel, 600-Watt Commercial Amplifier

Product Overview

The Atlas Sound HPA602 is a dual-channel 600-watt commercial power amplifier built for 70V/100V distributed audio systems and low-impedance sound reinforcement in the same chassis. Each channel delivers 300 watts into 70.7V, 100V, 8-ohm, or 4-ohm loads, giving integrators one amplifier SKU that covers paging zones, background music distribution, and direct-coupled loudspeaker systems. Generation II Class D output topology keeps the 2RU chassis compact and lightweight at 14.8 lbs while delivering the sound quality associated with Class AB designs. An accessory card slot accepts an optional two-channel Dante digital audio interface for networked AV installations.

Product Description

The HPA Series was designed for commercial amplifier installation projects where one platform must handle multiple impedance loads without output transformer compromises. The switch-mode power supply uses global auto-sensing 100–240V AC input and maintains stable output during fluctuating power conditions — a practical benefit in facilities with inconsistent mains quality. The power supply and output stage together deliver high dynamic output voltage and current to virtually any loudspeaker load, so the same amplifier drives long 70V speaker lines in a distributed paging system or 4-ohm loudspeaker clusters in a high-SPL reinforcement system.

Installation-focused details run throughout. Balanced inputs terminate on Euro block Phoenix-style connectors, front-panel stepped attenuators sit behind a security cover to prevent tampering in shared equipment rooms, and remote turn-on plus fault reporting support integration with control systems and monitored AV racks. The rear accessory slot accepts the optional Dante two-channel network audio card, letting system designers feed the amplifier directly from a Dante audio network without external interfaces. A low-resistance direct-coupled thermal transfer output design with a single variable-speed fan maintains optimal temperature across all loads and levels, and short-circuit, thermal, and DC offset protection guard connected loudspeakers. The HPA602 meets Energy Star standards, drawing only 1W in standby. Browse companion loudspeakers and signal processing in our AtlasIED collection.

Key Features

• Multi-Impedance Operation — Direct 4-ohm, 8-ohm, 70.7V, and 100V operation lets one amplifier serve both distributed audio and low-impedance loudspeaker systems.
• 2 x 300W Output — Both channels deliver a full 300 watts into every supported load for consistent system design math across zones.
• Generation II Class D Topology — High efficiency with Class AB sound quality keeps the chassis at 2RU and 14.8 lbs.
• Dante-Ready Card Slot — The rear accessory slot accepts an optional two-channel Dante digital network audio card for AV-over-IP integration.
• Global Auto-Sensing Power Supply — The 100–240V switch-mode supply maintains stable output through fluctuating mains conditions worldwide.
• Comprehensive Protection — Short-circuit, temperature, and DC offset protection safeguard the amplifier and connected loudspeakers.
• Secure Front-Panel Controls — Stepped detent attenuators behind a security cover prevent unauthorized level changes in shared racks.
• Remote Turn-On and Fault Reporting — Integration hooks support control system automation and proactive monitoring in managed facilities.
• Energy Star Efficiency — Standby power draw of only 1W lowers operating cost in always-on commercial deployments.

Frequently Asked Questions

Can the HPA602 drive both 70V speaker lines and 8-ohm speakers?

Yes. Each channel operates directly at 4-ohm, 8-ohm, 70.7V, or 100V, so you can run a distributed 70V zone on one channel and a low-impedance loudspeaker on the other.

Does it support Dante audio networking?

The rear accessory card slot accepts the optional AtlasIED two-channel Dante digital network audio card, enabling direct connection to a Dante network. The card is sold separately.

How much rack space does it need?

The HPA602 occupies 2RU in a standard 19" equipment rack and is 9.3" deep, fitting comfortably in shallow wall-mount AV racks.

Can it integrate with a control system?

Yes. Remote turn-on and fault reporting outputs allow integration with room control processors and monitored rack systems for automated power sequencing and alerting.

Will it work overseas or on unstable power?

The auto-sensing 100–240V switch-mode power supply handles global mains voltages and maintains stable output during fluctuating power conditions.

What warranty and support are included?

AtlasIED warrants the HPA602 for 60 months from date of purchase. Creation Networks provides pre-sale system design assistance and post-sale warranty support.
