AMP, HI PWR 4X300W@70V 2RU

Ideal Use Cases

The AtlasIED HPA1204 is a high-power commercial amplifier intended for large-format sound systems in halls, auditoriums, arenas, and similar applications. Its four channels each deliver 300 watts, providing up to 1200 watts of total output for connected loudspeakers. Support for 70.7V and 100V distributed systems, as well as 8-ohm and 4-ohm operation, allows the amplifier to serve several common commercial audio configurations. This combination is particularly useful when a system requires substantial multichannel output from a single rack-mounted component.

Why Choose This Model

The HPA1204 provides four 300-watt channels across every specified supported output configuration: 70.7V, 100V, 8 ohms, and 4 ohms. That consistent published output gives system designers a clearly defined power platform when working with distributed-voltage loudspeaker systems or conventional low-impedance loads. The amplifier also covers the full stated 20Hz to 20kHz frequency range and has a signal-to-noise ratio greater than 70dB, A-weighted. For installations requiring four amplified channels, it combines the complete 1200-watt rated output in a 2 RU chassis.

Installation and Integration

The amplifier is sized for standard 19-inch rack environments and occupies 2 RU. Its chassis measures 19 inches wide, 3.5 inches high, and 15 inches deep, or 483 by 89 by 381 millimeters. At 21.4 pounds, or 9.7 kilograms, its stated weight can be considered when planning rack support and equipment handling. Terminal block and Phoenix connectors are specified for system wiring. Universal voltage compatibility broadens its suitability for installations with differing power requirements. The maximum continuous current with all channels driven is 13.63A. A single variable-speed fan provides active chassis cooling, while the black finish fits typical commercial equipment racks.

Performance Highlights

Each of the four channels is rated at 300 watts for 70.7V, 100V, 8-ohm, and 4-ohm operation. With all four channels in use, the amplifier supplies up to 1200 watts of combined rated power. Its 20Hz to 20kHz frequency response spans the stated audible frequency range, supporting full-range commercial sound applications. The published signal-to-noise ratio is greater than 70dB A-weighted. Thermal planning data is also provided: with all channels driven under the stated AES condition, heat output is 1486 BTU at 70.7V and 120VAC. These published figures give integrators concrete electrical, thermal, and output information for system planning.

What Makes It Different

A defining feature of the HPA1204 is its ability to provide the same 4 x 300-watt rating across four supported operating formats. This lets one model address 70.7V and 100V commercial distribution systems along with 8-ohm and 4-ohm loudspeaker loads. The four-channel design consolidates substantial output capacity into two rack spaces, reducing the number of separate amplifier chassis needed to obtain four powered channels. Universal voltage compatibility, terminal block and Phoenix connectivity, and a variable-speed cooling fan further define the amplifier as a rack-oriented commercial audio component.

Final Assessment

The AtlasIED HPA1204 is suited to commercial sound projects that need four high-power channels and flexibility among distributed-voltage and low-impedance loudspeaker systems. Its 1200-watt total rating, 20Hz to 20kHz frequency response, 2 RU form factor, universal voltage compatibility, and documented current and thermal figures provide a practical specification set for planning demanding installations. A warranty period of 36 months from the date of purchase completes the supplied product information.
