AtlasIED CLA404 400W 4-Channel Multi Impedance Power Share Amplifier

Built for integrators who need reliable, flexible audio power across security, paging and AV systems, the AtlasIED CLA404 pro amplifier delivers 400W of intelligently managed amplification across four independent channels. AtlasIED's industry-first Power Share technology lets you prioritize zones and dynamically distribute available power so critical areas—guard stations, emergency points, or high-traffic lobbies—stay loud and clear even under heavy load. Each channel is user-configurable for 2, 4 or 8 ohm low-impedance loads or 25V/70.7V/100V distributed systems, removing the need for separate amplifiers in mixed installations. The CLA404's switch-mode, global auto-sensing power supply and convection with fan-assist on demand ensure stable, high-current output and quiet operation for surveillance monitoring rooms and security audio networks. At a compact 1RU half-rack form factor with remote level control and priority mute GPI, this amplifier streamlines installation and maintenance in control rooms, retail, education and enterprise deployments. Add the AtlasIED CLA404 to your next distributed audio or security monitoring project to simplify design and keep mission-critical zones powered—contact sales to specify or order.

• Patent-pending Power Share technology lets you dynamically allocate available power to priority zones for consistent coverage
• Per-channel multi-impedance switching (2/4/8Ω, 25V/70.7V/100V) simplifies mixed distributed and low-impedance installations
• Compact 1RU half-rack design with fan-assist on-demand saves rack space and reduces operating noise
• Energy-efficient 1W standby and priority mute GPI lower operating costs and support emergency paging workflows
• Remote level control and rear attenuators provide fast onsite tuning and centralized system integration
• Robust switch-mode, global auto-sensing power supply for reliable performance in fluctuating power environments
