HPR Series Specifications

The HPR Series offers performers the power, technology and legendary reliability of QSC amplification combined with the simplicity and convenience of powered loudspeaker systems. Whether your application is vocal reinforcement, dance music or full-tilt rock and roll sound, there’s an HPR speaker system for you.

Every HPR model is built around a high-power, reliable QSC power module using the same top-quality components and design standards as QSC RMX series amplifiers. Thick aluminum heat sink extrusions with deep fins provide mechanical strength and plenty of surface area to keep the module running cool. While many powered speaker amplifier modules use low-cost “chip amps”, the HPR series features discrete component designs that deliver the best possible performance even when pushed to the limit. The power modules incorporate sophisticated signal processing functions carefully tailored to the loudspeaker system. Each amplifier channel includes its own limiting with the parameters individually optimized for the frequency band.

All HPR models are constructed of rugged birch. The speaker components are protected by a heavy 16 gauge perforated steel grille with a distinctive and professional appearance. A grille-mounted power LED may be disabled by means of a rear-panel switch when desired. The HPR122i, HPR152i and HPR153i also feature integrated M10 suspension points for installed applications.
