AtlasIED CLA804 800W Four Channel Multi-Impedance Power Share Amplifier
The AtlasIED CLA804 is a high-performance four-channel amplifier delivering a powerful 800-Watt output with innovative Power Share technology, allowing dynamic power distribution across zones regardless of speaker impedance. Designed for both distributed 25V/70.7V/100V systems and low-impedance loads (2Ω, 4Ω, 8Ω), it offers versatile applications in sound reinforcement, paging, and background music environments.
Equipped with a global auto-sensing switch-mode power supply, the CLA804 ensures stable performance under varying electrical conditions. It achieves Energy Star efficiency, consuming less than 1W in standby, and primarily uses convection cooling with quiet fan assistance as needed. Housed in a compact 1RU half-rack chassis, it supports easy configuration and integration with remote level control, priority mute GPI, rear attenuators, and multiple GPI ports.
Rear-panel switches enable easy setup for individual channel loads and power sharing modes. With flexible output configurations and rugged construction, the CLA804 provides a reliable, scalable solution for multi-zone audio installations.
