Cinema Solutions Cinema Media Servers Standalone Integraded Media Block™ SX-4000

DTS:X™ Immersive Audio Solution

NEW! IAB support is available

DTS:X™ real-life, rich and immersive sound that moves around in the theatre


GDC SX-4000 Standalone Integrated Media Block™ is designed to anticipate the future of digital cinema sound. When combined with the 16-channel XSP-1000 Cinema Audio Processor (GDC Immersive Sound Solution), it supports 5.1/7.1 surround sound and the option for real-time decoding to playback DTS:X immersive sound. The option enables a high-quality audio experience at a price point that allows exhibitors worldwide to affordably install immersive sound in any size auditorium to deliver realistic, rich sound to a much broader audience. DTS:X delivers true cinematic immersion with best-in-class partners including Samsung Onyx LED, ScreenX and IMAX® Enhanced. Today, DTS:X is installed and committed in over 1,000 screens worldwide, including the world’s first and largest Samsung Onyx LED Cinema Screen with DTS:X.

Starting in 2020, SX-4000 would fully support SMPTE’s ST 2098-2 immersive audio bitstream (IAB) standard, which represents a major milestone toward the goal of delivering a single interoperable audio format for theatrical distribution. Supporting SMPTE’s IAB will bring even more immersive content to the big DTS:X screens worldwide – exactly as the filmmaker intended.
