Atlas Sound HPA2408 Eight-Channel, 2400-Watt Commercial Amplifier

Product Overview

The AtlasIED HPA2408 is an 8-channel commercial amplifier delivering 2,400 watts total (8 x 300W) for 25V, 70V, and 100V distributed audio systems as well as 8-ohm and 4-ohm low-impedance loads. Each channel's load can be configured independently, so a single 2RU chassis can drive a 70V paging zone, a low-impedance program loudspeaker, and everything in between. It is built for commercial AV integrators and consultants designing distributed sound system installations in campuses, government facilities, and large commercial buildings. Generation II Class D output topology keeps it compact, lightweight, and efficient enough to run on a single 15A circuit at 120V.

Product Description

The HPA Series is engineered for multi-zone amplifier installation where impedance flexibility matters: the HPA2408 handles 4-ohm, 8-ohm, 25V, 70V, and 100V loads with each channel independent of the others. Generation II Class D output topology provides high-efficiency amplification with sound quality comparable to a Class AB design, while the wide-range 100–240V power supply with power factor correction stays stable through fluctuating power conditions — a practical benefit in facilities with less-than-ideal electrical service. The PFC supply and efficient output stage together deliver high dynamic output voltage and current to virtually any loudspeaker load without demanding excessive AC power. Installer-focused details include front panel detented level controls behind a security cover, remote turn-on, balanced line inputs with selectable sensitivity, a BUSS input with individual channel assignments, stereo or parallel operating modes, and fault reporting for monitored commercial sound systems. An accessory card slot accepts an optional Dante eight-channel digital audio interface, allowing the amplifier to join a networked audio installation without external converters. Thermal management uses a low-resistance direct-couple thermal transfer output stage with multistage variable-speed fan cooling and removable air filters, and the amplifier meets Energy Star 1W standby standards to reduce operating cost. Pair the HPA2408 with a BlueBridge or Atmosphere DSP from our AtlasIED collection for a complete commercial audio amplification chain.

Key Features

• 8 x 300W Output — Eight channels at 300 watts each into 4-ohm, 8-ohm, 25V, 70V, or 100V loads, totaling 2,400 watts in 2RU.
• Independent Channel Loading — Each channel's impedance or constant-voltage load can differ, simplifying mixed 70V and low-impedance system design.
• Single 15A Circuit Operation — Requires only a 15A AC mains source at 120V, reducing electrical infrastructure for high-power installs.
• Dante-Ready Accessory Slot — Accepts an optional eight-channel Dante digital network audio card for networked AV system integration.
• Fault Reporting and Remote Turn-On — Supports monitored, centrally controlled commercial audio systems.
• Security-Covered Attenuators — Detented front-panel level controls sit behind a security cover to prevent tampering in shared spaces.
• Flexible Signal Routing — Selectable input sensitivity, stereo or parallel modes, and a BUSS input with per-channel assignments.
• Stable Global Power Supply — Wide-range 100–240V supply with power factor correction remains stable during fluctuating power conditions.
• Serviceable Cooling — Multistage variable-speed fan with removable air filters keeps maintenance simple in equipment rooms.
• Energy Star Standby — Meets Energy Star standards for 1W standby mode to cut idle power consumption.

Frequently Asked Questions

Can I mix 70V zones and 8-ohm speakers on the same amplifier?

Yes. Each of the eight channels can be loaded independently at 4 ohms, 8 ohms, 25V, 70V, or 100V, so one HPA2408 can serve mixed distributed and low-impedance loudspeaker designs.

Does the HPA2408 support Dante?

Dante is available via an optional eight-channel digital audio interface card that installs in the amplifier's accessory card slot; the base unit ships with balanced analog line inputs.

What electrical service does it need?

At 120V operation the amplifier requires only a 15A AC mains source, and its wide-range 100–240V PFC power supply supports global deployment.

How does it integrate with a control or monitoring system?

Remote turn-on and fault reporting allow the amplifier to be switched and monitored as part of a managed commercial AV installation.

Is it suitable for 24/7 operation in an equipment room?

The direct-couple thermal transfer output stage, multistage variable-speed fan, and removable air filters are designed for continuous commercial duty with simple maintenance.

What warranty applies?

AtlasIED provides a 36-month warranty from date of purchase, and Creation Networks offers pre-sale system design help and post-sale support.
