Description
The High Power Amplifier “HPA” Series is engineered to deliver versatility and performance for both commercial 70V/100V distributed audio systems and professional sound applications requiring amplifiers compatible with 4 and 2 ohm loads. This series stands out for being compact and lightweight while still offering power levels comparable to larger models. The HPA Series employs generation II Class I Output technology, achieving an efficiency similar to Class D amplifiers while maintaining the high sound quality of Class AB amplifiers. Its power supply features a switch-mode global auto-sensing generation 3 design, ensuring stable performance amidst fluctuating power conditions. Together, the power supply and output stage provide outstanding dynamic high output voltage and current suitable for virtually any loudspeaker load. Key features include front panel detented level controls with a security cover, remote turn-on capabilities, balanced inputs, fault reporting, and an accessory card slot for an optional Dante™ 2-channel digital audio interface. The unique low-resistance direct couple thermal transfer design of the output stage ensures cooling efficiency is maintained. Furthermore, the HPA Series is energy-efficient, meeting Energy Star standards by consuming only 1W of power in standby mode. Whether your requirement is for a large-scale constant voltage audio distribution system or a high SPL sound reinforcement solution, the HPA Series provides a powerful and cost-effective amplification solution.
