JBL Synthesis Introduces SDP-60 and SDP-70 Immersive AV Processors

Within the premium home cinema market, JBL Synthesis represents the system-driven approach of Harman Luxury Audio Group, focusing on complete, professionally planned solutions rather than individual components. As immersive audio formats and complex loudspeaker layouts become the norm in dedicated cinemas, demand is shifting toward dedicated AV processors that work seamlessly with external power amplifiers. The new JBL Synthesis SDP-60 and SDP-70 are positioned precisely in this environment, addressing installations where flexibility, signal integrity, and long-term expandability are key requirements.

Key Facts

• Dedicated immersive AV processors designed for use with external power amplifiers
• Two versions: SDP-60 with 16 channels, SDP-70 with up to 24 channels
• Full support for current immersive audio formats
• Integrated Dirac Live Active Room Treatment for advanced system-wide room optimization
• HDMI 2.1a architecture with support for 8K/60 Hz and 4K/120 Hz video
• Balanced XLR and unbalanced Cinch analog outputs
• Dante Audio over IP for professional audio distribution
• Comprehensive networking and streaming platform for modern media environments

Positioning and Differences: SDP-60 vs. SDP-70

The JBL Synthesis SDP-60 is configured as a 16-channel processor aimed at high-end home cinemas that require flexibility beyond conventional AV receivers while maintaining manageable system complexity. The SDP-70 expands this concept to a 24-channel processing platform, allowing integrators to realize particularly elaborate loudspeaker layouts with additional height and effect channels. In practice, this positions the SDP-70 as the preferred choice for very large, dedicated cinema rooms, while the SDP-60 offers a balanced solution for advanced residential installations.

Immersive Audio Formats and Matrix Channel Assignment

Both processors support Dolby Atmos, DTS:X Pro, IMAX Enhanced, and Auro-3D, covering the full range of contemporary immersive sound formats. A core feature is the matrix channel assignment capability, which allows any output channel to be freely assigned. For system designers and integrators, this translates into maximum freedom when implementing custom loudspeaker concepts without being constrained by fixed channel topologies.

Dirac Live ART for Advanced Room Optimization

A defining element of the SDP-60 and SDP-70 is the integration of Dirac Live Active Room Treatment. Unlike traditional room correction systems, Dirac Live ART treats the loudspeaker array as a cooperative system. In real-world installations, this enables more precise control of low-frequency behavior, smoother transitions between speakers and subwoofers, and a more coherent sound field—particularly beneficial in acoustically challenging cinema rooms.

Video Section and Connectivity for Modern Sources

On the video side, both models employ an HDMI 2.1a platform supporting resolutions up to 8K at 60 Hz and 4K at 120 Hz. Dynamic HDR formats such as HDR10+, Dolby Vision, and HLG are supported, alongside gaming-oriented features including Variable Refresh Rate and Auto Low Latency Mode. This makes the processors suitable not only for cinematic playback but also for high-performance gaming and streaming applications.

Networking, Streaming, and System Integration

Beyond signal processing, the SDP-60 and SDP-70 function as network-enabled media hubs. Supported services include Apple AirPlay, Google Cast, Spotify Connect, TIDAL Connect, Qobuz Connect, and Roon Ready. A Dante interface is included for audio distribution over IP networks, a key advantage in professional and large-scale installations. System setup and control are handled via the JBL Synthesis App, providing access to presets, source management, Internet radio, and podcasts.

Price and Availability

The JBL Synthesis SDP-60 16-Channel Immersive AV Processor is offered at a recommended retail price of € 6.199,-. The JBL Synthesis SDP-70 24-Channel Immersive AV Processor is priced at € 10.599,-. Both models are expected to become available shortly through authorized JBL Synthesis dealers.

Conclusion

With the SDP-60 and SDP-70, Harman Luxury Audio Group, through the JBL Synthesis brand, reinforces its focus on fully scalable, professionally oriented home cinema solutions. High channel counts, flexible signal routing, a modern HDMI 2.1 video architecture, and the integration of Dirac Live ART position both processors as powerful control centers for ambitious immersive cinema projects, clearly aimed at long-term system planning and precise custom installation.
