Three-Way Bi-Amplified ScreenArray® Cinema Loudspeaker System

The JBL Professional 4832 Three-Way Bi-Amplified ScreenArray® Cinema Loudspeaker System is ideal for 150 – 250 seat cinemas. The JBL Professional 4832 Three-Way Bi-Amplified ScreenArray® Cinema Loudspeaker System is ideal for 150 – 250 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 high power critical sound reproduction in premier cinemas, studio production and post-production applications, the 4832 next-generation ScreenArray features true three-way design 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.
