The AtlasIED CP700 is a professional 2-channel Class A/B power amplifier designed for demanding commercial paging, distributed audio, and sound reinforcement installations. Featuring transformer-isolated constant-voltage outputs, direct-coupled low-impedance outputs, and a rugged 3RU rackmount chassis, the CP700 provides flexible amplification for commercial and institutional sound systems.
The amplifier delivers 350 watts per channel at 70.7V, 400 watts per channel at 4 ohms, and supports 700-watt bridged-mono operation at 140V/200V, allowing installers to configure the amplifier for different system requirements.
With 25V, 70.7V, and 100V constant-voltage outputs, along with 2-ohm, 4-ohm, and 8-ohm low-impedance operation, the CP700 accommodates a wide range of professional speaker configurations.
Its Class A/B amplifier design incorporates toroidal power supply and output transformers, balanced input connections, adjustable output levels, and automatic cooling to support reliable operation in commercial environments.
Whether you're designing a large distributed paging system, upgrading an existing commercial audio installation, or powering professional sound reinforcement equipment, the AtlasIED CP700 provides a versatile amplification solution.
High-Power Two-Channel Amplification
The AtlasIED CP700 features two independent amplifier channels designed to provide reliable power for commercial sound systems.
Its output capabilities include:
|
Operating Mode
|
Rated Output Power
|
|
70.7V Constant-Voltage
|
350W per Channel
|
|
4-Ohm Low-Impedance
|
400W per Channel
|
|
140V/200V Bridged Mono
|
700W Total
|
These configurations allow the amplifier to support both distributed audio installations and compatible low-impedance loudspeaker systems.
The two-channel design is useful for applications requiring separate amplifier outputs, while bridged-mono operation provides an alternative for appropriately designed high-voltage distributed systems.
Important: The amplifier's available output power depends on the selected operating mode and connected speaker load.
Transformer-Isolated Constant-Voltage Outputs
One of the CP700's distinguishing features is its use of toroidal output transformers for constant-voltage speaker operation.
The amplifier supports:
-
25V distributed audio systems
-
70.7V distributed audio systems
-
100V distributed audio systems
Transformer-isolated outputs are particularly useful for commercial paging and distributed audio installations where multiple transformer-equipped loudspeakers are connected along a speaker line.
The output transformers provide electrical isolation between the amplifier circuitry and the constant-voltage speaker outputs.
This design makes the CP700 suitable for commercial installations requiring traditional transformer-coupled amplifier architecture.
Direct-Coupled Low-Impedance Speaker Outputs
In addition to its constant-voltage outputs, the AtlasIED CP700 supports direct-coupled low-impedance operation.
Supported speaker impedances include:
This flexibility allows the amplifier to power compatible low-impedance loudspeakers used in commercial sound reinforcement systems.
The CP700 is particularly useful when an installation requires the flexibility to select between conventional low-impedance loudspeakers and transformer-equipped distributed audio systems.
Amplifier output connections and operating modes must be selected according to AtlasIED's installation instructions.
Class A/B Amplifier Design
The AtlasIED CP700 uses Class A/B amplifier topology, providing a traditional professional amplification architecture designed for demanding commercial applications.
Its design incorporates high-quality toroidal power supply components and output transformers.
These components support stable amplifier operation and provide transformer isolation for the constant-voltage outputs.
The CP700 is designed for installations where dependable amplification, flexible speaker connections, and professional-grade construction are important.
Balanced XLR and Terminal Block Inputs
The CP700 provides flexible audio input connectivity for integration with professional mixers, audio processors, paging equipment, and other line-level audio sources.
Connection options include:
-
Balanced XLR audio inputs
-
Terminal block input connections
-
XLR loop-through connections
-
Rear-panel stepped level attenuators
Balanced input connections help support professional audio installations where equipment may be located in separate racks or connected over longer cable runs.
The XLR loop-through connections provide convenient signal routing to additional compatible equipment.
Rear-panel attenuators allow installers to adjust amplifier input levels while keeping the controls away from casual access.
Automatic Cooling and Amplifier Protection
The AtlasIED CP700 incorporates an automatic cooling system designed to help maintain appropriate operating temperatures.
The amplifier features one variable-speed cooling fan.
Its cooling system adjusts fan operation according to amplifier requirements, helping manage heat during extended operation.
Additional protection features include power-up muting, which helps reduce unwanted audio transients during amplifier startup.
The CP700 also includes barrier strip speaker output connections with protective covers.
Proper rack ventilation and manufacturer-recommended installation clearances should be maintained.
Rugged 3RU Rackmount Construction
The CP700 is designed for installation in professional equipment racks.
Its 3RU chassis provides space for the amplifier's internal power supply, output transformers, cooling components, and connection hardware.
The amplifier features a black finish suitable for commercial AV equipment racks.
Its construction makes it appropriate for permanent installations in equipment rooms, commercial sound system racks, and institutional audio facilities.
