JBL and the Movies grew up together. It’s a quantum leap from the first movie sound system that premiered in 1928 with “The Jazz Singer” to the astonishingly realistic THX®-certified sound systems that reproduce the digital sound we enjoy today. And JBL has been there every step of the way.

With the introduction of JBL Synthesis in 1990, JBL established a reputation for offering the best home theater systems available on the market. Since then JBL has been a leading innovator in home theater products that set the standard for performance.

Now there is a new addition to our proud heritage of electronics: the JBL Synthesis SDP-40 Digital Surround Processor/Controller. The SDP-40 offers both balanced and unbalanced outputs and is the culmination of years of research in room acoustics, psychoacoustics, and audio creation and reproduction.
