AtlasIED CLA404 400‑Watt Four Channel Multi‑Impedance Power Share Amplifier
The AtlasIED CLA404 is a high-performance 400‑Watt four-channel amplifier featuring advanced Power Share technology for adjustable power distribution across different zones regardless of speaker impedance. Ideal for commercial installations, it supports constant-voltage systems (25V, 70.7V, 100V) as well as low-impedance loads (2Ω, 4Ω, 8Ω), offering ultimate flexibility for sound reinforcement and distributed audio applications.
Equipped with a switch-mode, global auto-sensing power supply, the CLA404 ensures stable output under varying power conditions while maintaining efficiency. In standby, it consumes under 1W and operates convection-cooled, with whisper-quiet fan assist when required. Housed in a compact 1RU half-rack chassis, it includes rear panel switches for easy load and power configuration per channel, along with remote level control, priority mute GPI, rear attenuators, and multiple GPI ports for enhanced integration.
Rugged, efficient, and versatile, the CLA404 is an ideal solution for delivering reliable audio performance in multi-zone systems, paging setups, and high-SPL applications, all with professional-grade control and connectivity.
