The AtlasIED CLA402 is a 2-channel, 400-watt amplifier built for both constant voltage (25V, 70.7V, 100V) and low impedance (2Ω, 4Ω, 8Ω) speaker systems. Featuring patent-pending Power Share technology, the CLA402 allows each channel to be configured independently—making it the ideal solution for complex multi-zone audio systems where flexibility and precise power control are key.
With switch-mode, auto-sensing global power supply, the CLA402 guarantees stable performance even in environments with fluctuating voltage. Power sharing configurations let integrators easily assign power (up to 350W on a single channel) depending on the needs of each zone. All settings are configured via intuitive rear-panel dip switches, reducing setup time.
Designed to operate efficiently and quietly, the CLA402 features a thermal-optimized output stage, convection cooling, and fan-on-demand functionality. It meets Energy Star standards, drawing less than 1W in standby, making it a green choice for commercial projects.
Whether powering foreground music, paging, or large distributed systems, the CLA402 delivers unmatched power-to-size ratio, reliability, and versatility—all from a compact 1RU half-rack chassis.
