AtlasIED - HPA4202

The AtlasIED High Power Amplifier “HPA” Series has been designed to be versatile for uses in both commercial 70V/100V distributed systems and professional applications that require amplifiers to handle 4 and 2 ohm loads. The HPA is compact and lightweight in comparison to other models delivering the similar power levels. The HPA Series features generation II Class I Output topology that gives the efficiency close to a Class D amplifier with the sound quality of a Class AB amplifier. The power supply is switch mode global auto sensing gen 3 design that maintains a stable output during fluxuating power conditions. The power supply and output stage collectively are designed to deliver exceptional dynamic high output voltage and
current to virtually any speaker load.

The HPA Series features front panel detented level controls with a security cover, remote turn on, balanced inputs, fault reporting and an accessory card slot for an optional Dante™ 2-channel digital audio interface. Cooling is not an issue because of the unique output stage low resistance direct couple thermal transfer design. HPA also is energy efficient and meets Energy Starr standards with only drawing 1W of power in standby mode.

Whether your application is a large distributed constant voltage sound system or a high SPL sound reinforcement system, the Atlas Sound HPA Series is the answer for high power/cost effective amplification need
