A processor designed for the home theaters of the future

With 36 discrete channels, the SDP-80 enables the realization of large-scale immersive home theaters, where speaker placement and channel definition can be utilized without limitations. The DSP platform works with high resolution and low latency, so even complex soundtracks are reproduced with accuracy, dynamics and an impressive sense of physical presence.

The processor is pre-configured with JBL Synthesis' own EQ profiles and Harman Target curves, so from the first setup it delivers a sound signature that matches the reference performance of Synthesis systems.

Trinnov Optimizer – the most advanced room correction on the market

The SDP-80 features Trinnov Optimizer, which not only corrects frequency response and time domain, but also analyzes the position of the speakers in the room with three-dimensional precision. This makes it possible to create a coherent and completely accurate reproduction, even in complex rooms or setups with many speakers.

The optimizer's integration is complemented by JBL Synthesis' own fine-tuning, ensuring synergy between electronics and speakers – a central element of the characteristic Synthesis soundscape.

HDMI 2.1 with full bandwidth and next-generation image formats

HDMI 2.1 supports video streams up to 8K at 60 fps and 4K at 120 fps. This provides maximum flexibility for modern projectors, TV solutions and gaming sources, and ensures that the processor can handle all image and audio formats without restrictions. HDR formats such as Dolby Vision and HDR10+ are transmitted with full quality loss, so both films and streaming content are optimally utilized.

Reference-level connections, control and integration

Designed as a professional tool for high-end installations, the SDP-80 offers extensive control options via IP, triggers, and standardized control protocols, making integration into larger Synthesis installations, Control4 systems, and other automation solutions both simple and robust.
