JBL Synthesis SDP-75 3D Surround Processor (16 Channels)

The JBL Synthesis SDP-75 is JBL’s flagship immersive surround processor, positioned at the very top of the Synthesis electronics range. Built on the renowned Trinnov Altitude platform and extensively customised for JBL Synthesis, the SDP-75 is one of the most advanced home cinema processors available, designed for reference-grade multi-channel decoding, room correction, and system optimisation.

The 16-channel version offers full discrete immersive audio decoding for advanced home theatre layouts such as:

• 9.1.6
• 7.4.4
• 7.2.6
• 5.4.6

Its biggest strength lies in the integration of Trinnov Optimizer with JBL Synthesis speaker presets, allowing exceptionally precise phase, timing, bass management, and room correction calibration.
