Reference performance for modern home theaters

JBL Synthesis SDP-70 is designed to deliver high sound quality for both movies and music. The advanced signal processing combined with a high-resolution DAC architecture ensures precise processing of all channels, so dialogue, music, and sound effects are reproduced with great detail and accuracy.

The result is a cohesive soundstage with high dynamics, precise placement of sound effects, and natural reproduction that supports both movie experiences and music listening.

Supports the leading surround formats

SDP-70 supports Dolby Atmos, DTS Pro, Auro-3D, and IMAX Enhanced. This makes it possible to configure everything from traditional 5.1 and 7.1 systems to large object-based home theaters with height and ceiling channels.

The flexible Matrix Channel Assignment also makes it possible to adapt the channel distribution precisely to the room layout and speaker configuration.

Dirac Live Room Correction

The integrated Dirac Live Room Correction analyzes both the speakers and the room acoustics and optimizes frequency response, phase, and timing.

This provides more balanced and precise sound reproduction, where dialogue becomes clearer, effects are placed more accurately, and the music appears more cohesive – even in rooms with acoustic challenges.

Streaming and modern connectivity

SDP-70 functions as both a surround processor and a music streamer. Support for Apple AirPlay 2, Google Cast, Spotify Connect, TIDAL Connect, Qobuz Connect, and Roon Ready makes it easy to stream music directly from popular services.

HDMI with eARC ensures simple integration with TVs and modern video sources, making both sound and operation a natural part of the home theater.

Flexible installation

Balanced XLR outputs provide optimal signal transfer to external power amplifiers, while Dante Input/Output makes the SDP-70 suitable for both advanced private home theaters and professional AV installations.

The system is configured via the JBL Synthesis App, where room correction, streaming, and system settings are gathered in one clear user interface.

What is JBL Synthesis?

JBL Synthesis is built on the same philosophy and technology used in JBL's professional cinema systems. The goal is to bring an authentic cinema experience into private home theaters through carefully matched electronics, speakers, and room correction.

The SDP-70 forms the heart of this solution and serves as the control center for the entire system with advanced signal processing and extensive customization options.
