AtlasIED CLA402 400-Watt Two Channel Multi Impedance Power Share Amplifier

The AtlasIED CLA402 is a powerful 400-Watt two-channel multi-impedance amplifier designed for diverse commercial audio applications. Featuring innovative Power Share technology, it allows precise power distribution across different zones regardless of speaker load impedance. This amplifier supports distributed constant voltage systems of 25V, 70.7V, and 100V, as well as low impedance loads of 2, 4, or 8 ohms, making it ideal for both sound reinforcement and distributed audio installations.

Equipped with a switch-mode global auto-sensing power supply, the CLA402 delivers consistent, high-quality output even under varying power conditions. Its energy-efficient design meets Energy Star standards with less than 1W power consumption in standby mode. The amplifier uses convection cooling with fan assist when needed to maintain optimal thermal performance. Compact and rack-mountable in a 1RU half rack chassis, the CLA402 is a versatile and reliable solution for multi-zone audio amplification needs.

Configuring power share and speaker load per channel is easy using rear panel switches, allowing flexible power allocation and load management. Additional features include remote level control, priority mute GPI, rear attenuators, and multiple GPI ports for enhanced control and integration into complex audio systems.
