AMP PWR SHR 4CH 800W 1RU

The AtlasIED CLA804 is an 800W, four-channel Class D power amplifier designed for commercial distributed audio and low-impedance sound reinforcement. Its multi-impedance design supports 2-, 4-, and 8-ohm loads, as well as 25V, 70V, and 100V systems. Leveraging AtlasIED’s Power Share technology, it allocates precise power levels to each zone, offering flexibility in system design and efficient distribution of output.

Ideal Use Cases

The CLA804 shines in multi-zone installations requiring a compact setup. Ideal applications include restaurants, presentation rooms, classrooms, conference rooms, and retail spaces needing background or foreground music. Its four-channel, 800W capability is perfect for serving multiple listening areas with a single amplifier.

With support for both commercial distributed systems and low-impedance sound reinforcement, the CLA804 adapts to a variety of speaker configurations. This versatility is particularly beneficial when installations involve diverse zone requirements or existing speaker systems.

Why Choose This Model

The key advantage of the CLA804 is its Power Share technology. Unlike traditional amplifiers that assume uniform zone requirements, this model directs precise power levels to each zone, optimizing power use based on load. This feature enhances the planning and execution of multi-zone systems.

Its four-channel architecture, paired with four inputs, simplifies integration into existing systems. The Class D topology fits 800W of total output into a 1 RU, half-rack-width chassis, making it especially valuable in space-constrained environments.

Installation and Integration

The CLA804 measures 1.75 inches high, 8.75 inches wide, and 13.5 inches deep (44 x 222 x 343 mm). It fits a 1 RU, 8.5-inch-wide half-rack, weighing just 8 lbs (3.64 kg). This compact form is ideal for commercial audio racks.

For connectivity, it features four removable, locking Euro Block terminals with a 5.08mm pitch for speaker connections, and seven GPI ports using 3.5mm Euro Block connections. These secure, removable terminations support robust system integration.

Cooling adapts to operational conditions: convection cooling when idle and a variable fan when active. Shipping dimensions are 4.5 x 17.25 x 11.75 inches (114 x 438 x 298 mm), with a shipping weight of 11.2 lbs (5.06 kg).

Performance Highlights

Delivering 800W across four channels, the CLA804's frequency response is 20Hz to 20kHz at +0/-1.5dB for 2-, 4-, and 8-ohm loads and 25V operation; 50Hz to 20kHz for 70V and 100V modes. It maintains total harmonic distortion at ≤0.15% at 1kHz and 1dB below rated power.

Its signal-to-noise ratio exceeds 93dBA below rated output for 8-ohm operation, A-weighted, ensuring clear, distortion-free audio for both low-impedance and distributed-voltage systems.

What Makes It Different

Combining four-channel amplification, multi-impedance operation, and Power Share technology, the CLA804 is a distinctive choice for both sound reinforcement and distributed audio. Supporting various impedance loads, it offers a flexible solution for diverse audio projects.

The compact, half-rack-width, 1 RU format provides four channels and 800W of output without needing a larger chassis. Removable locking terminals, multiple GPI ports, and responsive cooling further distinguish its installation suitability.

Final Assessment

The AtlasIED CLA804 is ideal for multi-zone commercial audio systems needing significant output, multiple channels, and broad speaker load compatibility. Power Share functionality, impedance versatility, four inputs, and compact design make it perfect for restaurants, educational spaces, meeting rooms, presentation venues, and retail music systems.

A 36-month warranty from purchase complements its robust feature set. For installations requiring an 800W Class D amplifier capable of both distributed-voltage and low-impedance applications, the CLA804 delivers a well-rounded mix of power, connectivity, and installation adaptability.
