Two-Way Passive ScreenArray™ Cinema Loudspeaker System

The JBL Professional 3822N Two-Way Passive ScreenArray™ Cinema Loudspeaker System is ideal for 100 – 150 seat cinemas. Today’s premier cinemas require perfect coverage in every seat of the auditorium, wide dynamic range and extended bandwidth, as well as inaudible levels of distortion. Digital soundtracks, especially those associated with the latest digital cinema requirements, require sound systems that can accurately reproduce the sound exactly as recorded.

Designed for film sound reproduction, the 3822N ScreenArray provides smooth and accurate reproduction of cinema soundtracks in a compact system. The ScreenArray horn features a patented design that compensates for high frequency spreading caused by perforated screens for greatly improved audience coverage.

The 3822N next-generation ScreenArray is enhanced by advanced engineering. JBL’s latest technical innovations are integrated into a system design that provides superior coverage, maximum power handling, and uniform acoustic power output, along with extremely low distortion. The ScreenArray design provides ideal power response and directivity control with seamless transitions between acoustic sections.
