AMP, 200W/CH 70.7V 240W/CH 4 OHM

Ideal Use Cases

The AtlasIED CP400 is a two-channel commercial power amplifier for audio systems requiring low-impedance loudspeaker loads or constant-voltage operation. It supplies 200 watts per channel in 70.7V stereo and 175 watts per channel in 25V stereo. For low-impedance stereo configurations, its published ratings are 160 watts per channel at 8 ohms, 240 watts per channel at 4 ohms, and 270 watts per channel at 2 ohms. These operating modes make the CP400 suitable when a commercial system design calls for two amplified channels and one of these specific load configurations.

Why Choose This Model

The CP400 combines two-channel operation with several stereo and bridged-mono power options. Its 70.7V rating matches applications specified for 200 watts per channel, while its 4-ohm stereo rating provides 240 watts per channel. When a single bridged channel is required, the amplifier is rated for 500 watts at 8 ohms or 600 watts at 4 ohms. It also provides a listed 400-watt bridged-mono rating for 140V/200V operation. This range allows system requirements to be matched against clearly documented output figures.

Installation and Integration

Connection options include XLR and terminal-block formats, giving an installer two documented connector types for integration. The amplifier is compatible with 110V-120V electrical service and has a black finish. Its stated height is 5 3/16 inches, or 13 centimeters, which should be considered when allocating equipment space. Cooling is provided by one variable-speed fan. Before installation, the selected stereo or bridged-mono mode should be checked against the intended system voltage, loudspeaker load, and required channel arrangement.

The CP400 supports 25V and 70.7V stereo operation as well as 140V/200V bridged-mono operation. Low-impedance choices cover 2-ohm, 4-ohm, and 8-ohm stereo loads, plus 4-ohm and 8-ohm bridged-mono configurations. This documented selection gives system designers concrete operating points for configuring the amplifier around an established audio specification.

Performance Highlights

• 70.7V stereo: 200 watts across each of two channels.
• 25V stereo: 175 watts across each of two channels.
• 8-ohm stereo: 160 watts across each of two channels.
• 4-ohm stereo: 240 watts across each of two channels.
• 2-ohm stereo: 270 watts across each of two channels.
• 8-ohm bridged mono: 500 watts.
• 4-ohm bridged mono: 600 watts.
• 140V/200V bridged mono: 400 watts.

Frequency response is specified from 30Hz to 50kHz at ±3dB. Together with its two-channel architecture, the multiple power ratings let buyers evaluate the CP400 using the exact operating mode relevant to their planned system rather than relying on a single generalized wattage figure.

What Makes It Different

The defining feature of the CP400 is the breadth of configurations documented for one commercial amplifier. It is not limited to a single loudspeaker impedance or constant-voltage format: the supplied specifications cover three low-impedance stereo ratings, two low-impedance bridged-mono ratings, two constant-voltage stereo formats, and a high-voltage bridged-mono format. XLR and terminal-block connectivity, a variable-speed fan, and 110V-120V compatibility complete the listed integration details.

Final Assessment

The AtlasIED CP400 is a focused choice for a two-channel commercial audio system requiring specific, published output ratings. Its key figures are 200 watts per channel at 70.7V and 240 watts per channel at 4 ohms, supported by additional stereo and bridged-mono modes. With a 30Hz-50kHz frequency response, two connector formats, and a 36-month warranty from the date of purchase, the CP400 presents a clearly specified combination of power and configuration options.
