CP400 & CP700 Commercial Power Amplifier Owner’s Manual INTRODUCTION Congratulations and thank you for purchasing the Atlas Sound CP400/CP700 dual channel power amplifier. This product is a professional grade audio power amplifier specifically designed for demanding contractor applications and engineered to provide years of faithful service. Two independent channels driven by separate power supplies ensure maximum channel separation and ultra low distortion figures.

Power Switch This rocker switch supplies power to the amplifier. A red LED located above the power CH-1 CH-1 AMPLIFIER INPUTS switch will illuminate when the amplifier is switched on. IN CP700 Commercial Power Amplifier 8, 4, and 2 Ohms DIR.
CP400 & CP700 Commercial Power Amplifier Owner’s Manual 4. Limit LED Indicator The CP400 and CP700 come equipped with limiter circuitry and LEDs to indicate when this circuitry is activated. The limiter circuitry engages only when the input signals reach a specific, CP700 factory set magnitude. Once this limit has been reached, the circuitry will reduce the input level enough to prevent clipping at the speaker output terminals.
CP400 & CP700 Commercial Power Amplifier Owner’s Manual 9. Stereo/Parallel/Bridge Switch This 3 position switch changes the operating mode of the amplifier. DO NOT move this switch when the amplifier is powered up and connected to a load. • Stereo - When the switch is set to this position, the amplifier operates as two independent amplifiers. Use this position for stereo program material or for two discreet paging/sound masking zones.
CP400 & CP700 CP700 Owner’s Manual POWER Commercial Power Amplifier Commercial Power Amplifier Input Wiring Balanced Inputs Balanced input wiring requires two conductors with shield (22-gauge is the most common). The use of crimp type spade lugs is highly recommended for permanent installations.
CP700 POWER Commercial Power Amplifier CP400 & CP700 Commercial Power Amplifier Owner’s Manual Unbalanced Input Unbalanced wiring typically is found on consumer equipment (CD players, DVD players, etc.) and is generally a compromise of noise rejection and cable lengths. A single conductor and an overall shield are most common, as in the standard cables supplied with consumer equipment.
