4 Channel Multi Impedance 400W Power Share Amplifier;

The AtlasIED CLA404 is a four-channel, 400W multi-impedance amplifier featuring AtlasIED's Patent-Pending Power Share technology. This innovative feature is an industry first, allowing for controllable power levels to be accurately applied to different zones regardless of the load impedance.

Designed for versatility, the CLA404 amplifier is suitable for both commercial 25V/70.7V/100V distributed systems and sound reinforcement applications requiring amplification for low impedance loads like 2, 4, or 8 ohms. The amplifier's power supply adopts a switch- mode, global auto-sensing design, ensuring a stable output even in fluctuating power conditions. The power supply and output stage are meticulously engineered to deliver exceptional dynamic high output voltage and current simultaneously to virtually any loudspeaker load.

Configuring each channel's Power Share level and speaker load is fast and simplistic with the CLA amplifier. Simply select the desired power level and load type via the switches located on the rear panel.

Other key features of the CLA Series include a unique output stage with a low- resistance, direct-coupled thermal transfer design, effectively maintaining optimal temperature across all loads and output levels. Additionally, the CLA Series amplifiers are energy-efficient, meeting Energy Star standards consuming less than 1W of power in standby mode. The CLA Series amplifiers are so efficient, generating little heat, most of the time they operate in a convection cooled state. If additional cooling is required, the variable speed whisper quiet fans will engage.

Whether your application involves a large distributed constant voltage sound system, a high SPL sound reinforcement system, or both, the AtlasIED CLA Series is the solution for a multi-functional, high-power, and cost-effective amplifier.
