Eight-Channel 2400-Watt Commercial Amplifier

Ideal Use Cases

The AtlasIED HPA2408 is an eight-channel commercial amplifier built for large-format applications that require substantial loudspeaker power from a rack-mounted component. Its 2400-watt total power output makes it suitable for halls, auditoriums, arenas, and similar spaces. The amplifier can be configured for several common commercial audio formats, including 100V, 70.7V, 25V, 8-ohm, and 4-ohm operation. This flexibility supports system designs based on distributed-voltage loudspeaker lines or low-impedance loudspeakers without changing to a different amplifier model.

Why Choose This Model

The HPA2408 combines eight amplifier channels with clearly specified output across multiple operating formats. It provides 8 x 300 watts at 100V, 70.7V, 8 ohms, and 4 ohms, while its 25V configuration supplies 8 x 200 watts. Total rated power output is 2400 watts. These ratings give system designers concrete channel-level figures for matching the amplifier to connected loudspeakers. A 2-ohm output rating is listed as not available, making the supported operating configurations straightforward to identify during system planning.

Installation and Integration

A 2 RU chassis allows the HPA2408 to fit into a commercial equipment rack while providing eight channels of amplification. The enclosure measures 19 inches wide, 3.5 inches high, and 15 inches deep, equivalent to 483 x 89 x 381mm. Its listed weight is 21.4 pounds, or 9.7kg. Terminal block and Phoenix connector types are specified for system wiring. Universal voltage compatibility supports deployment where differing supply voltages must be accommodated. Cooling is provided by one variable-speed fan, and the amplifier has a black finish that suits conventional installed-audio racks.

Performance Highlights

The amplifier has a stated frequency response of 20Hz to 20kHz with a tolerance of +0/-1.5dB. Its signal-to-noise ratio is greater than 70dB. Across the supported 100V, 70.7V, 8-ohm, and 4-ohm configurations, each of the eight channels is rated for 300 watts. At 25V, each channel is rated for 200 watts. This documented output range lets buyers evaluate the amplifier against the load format and power requirements of their loudspeaker system rather than relying only on the 2400-watt total rating.

What Makes It Different

The defining feature of the HPA2408 is the combination of eight channels, high total output, and support for both commercial distributed-voltage formats and common low-impedance loads. Its 100V and 70.7V ratings address large-format commercial loudspeaker systems, while 8-ohm and 4-ohm compatibility expands the available system configurations. The supported 25V mode provides another distributed-voltage option. These capabilities are housed in a 2 RU enclosure with universal voltage compatibility, terminal block and Phoenix connectivity, and variable-speed fan cooling. The included warranty period is 36 months from the date of purchase.

Final Assessment

The AtlasIED HPA2408 is a focused choice for commercial systems that need eight powered channels and as much as 2400 watts of total output. Its published channel ratings cover 100V, 70.7V, 25V, 8-ohm, and 4-ohm configurations, making it applicable to several established loudspeaker formats. A full 20Hz to 20kHz frequency response, greater-than-70dB signal-to-noise ratio, universal voltage compatibility, and a rack-ready 2 RU form factor complete the specification set. For halls, auditoriums, arenas, and other large-format applications, it provides a clearly documented balance of channel count, configuration flexibility, and output capacity.
