HIGH PERFORMANCE STEREO HAS LED THE MOTION
PICTURE INDUSTRY WITH 34 YEARS OF INNOVATION
AND SUPERIOR CINEMA SOUND SYSTEM QUALITY
Since 1979, High Performance Stereo has been the industry leader in motion picture sound systems. Work on the HPS-4000® system began in 1979. The goal was to create a sound system that would deliver all the dynamics and nuances of the analog soundtracks of the day as well as the digital recordings of the future.
Over the years, High Performance Stereo has led the industry with an impressive list of firsts. Perhaps most importantly, we were the first to develop a wide range stereo playback system for modern cinemas. Before the introduction of the HPS-4000® sound system, no theatre sound system offered a nine octave response.
The first HPS-4000® installation occurred in 1980. It was an immediate success. In fact, attendance at the theatre increased 25 percent in the first year following the sound systems installation. Indeed, attendance increases at HPS-4000® equipped theatres have ranged form 20 to 300 percent.
Since then, High Performance Stereo has introduced most of the the important innovations in cinema loudspeakers and sound systems. HPS® was the first to develop reliable formulas for the exact placement of the all important surround speakers. These proprietary formulas work because they relate the radiating patterns of the surround speakers themselves to the actual shape of the individual theatre. Known as the ALLEN SURROUND ARRAY, this is something weve become quite proud of. Unheard of coverage uniformity of ±1/2 dB within the surrounded area is typical. No single speaker localization is noticed, even by those sitting directly underneath a surround speaker. No other motion picture surround system offers this level of performance.
The sound quality of the ALLEN SURROUND ARRAY matches the sound from the screen. This again is exclusive with the HPS-4000® installations. Indeed, one competitor publicly stated that they tried and failed to achieve timbre matching between the screen and surround channels. We did it 34 years ago.
We were also first to computerize theatre sound system designs in 1982, the first to export modern theatre playback systems overseas (also 1982), first to offer modern 3-way speakers to be used behind the screen (1979), the first to offer 4-way screen loudspeakers (1984) and first (and still the only sound company) to install every one of our motion picture sound systems with ALL the dynamic range required for digital stereo (1980)!
High Performance Stereo was privileged to be the first to demonstrate digital stereo in a commercial movie theatre in 1984. This was followed with two highly successful, first ever, digital stereo motion picture feature presentations for the public in 1985.
