Use the Harman Luxury MusicLife™ app to play your own music library from a computer or NAS drive, or play directly from a USB flash drive. There’s even a DAB/FM antenna for OTA radio!

Superior Video

Advanced circuitry and decades of know-how ensure the 4K “Ultra HD” video signal is perfectly clear and rock solid. The video stages are designed to harness the latest technology and deliver the best quality formats including Dolby Vision™, HLG, HDR10, HDR10 , HDMI2.0b with HDCP2.2, and 3D video capabilities built-in.

IMAX Enhanced

The JBL Synthesis SDP-55 is an IMAX Enhanced-certified AV receiver and features DTS:X immersive audio decoding that is optimized to properly reproduce the full dynamic range of IMAX theatrical sound mixes available in IMAX Enhanced content. With meticulous adjustments modeled on the IMAX theatrical sound system, this proprietary IMAX audio mix is translated for home theater environments and exclusively delivered using a special variant of the DTS:X CODEC technology to deliver the IMAX signature sound experience in the home.

A More Dramatic TV Experience

Dolby Vision™ is superior HDR. Using the same underlying technology as the most advanced movie theatres, Dolby Vision enables an enhanced image through superior content and smarter TV display performance.

Audiophile Quality

The JBL Synthesis SDP-55 leverages the 24bit /192k ESS® Sabre 9028 Pro featuring -120dB THD N for D/A conversion. The analog circuitry on the input and output stages is optimized for unequaled dynamic range, ultra-low distortion, and unmatched audio clarity. Carefully designed anti-jitter circuitry and ultra-clean power supplies are incorporated to ensure all audio paths, including HDMI, are uncompromised.


With 15.1 decoding, 9.1.6 preamp outputs, both balanced XLR, and single-ended RCA, independent Zone 2 combined with RS232, Ethernet and app control, the SDP-55 offers exceptional versatility. Four of the sixteen channels allow independent volume and delay settings for added configuration options. Independent volume control for the subwoofers allow fine-tuning, and front panel headphone and aux (3.5mm) jacks add convenience. The JBL Synthesis Control app enables complete control of the SDP-55 with an Android or iOS device. Flexible configuration, including Dante, IP, IR, and RS232 control and a Zone 2 with high-resolution audio, 4K video, IR, and triggers, make the SDP-55 an outstanding choice for a broad range of applications.


The JBL Synthesis SDP-55 includes Dante, an uncompressed, multi-channel digital media networking technology, with near-zero latency and synchronization. All 16 channels of processed audio, plus Zone 2 (18 channels total) can be routed to any Dante enabled receiving device over a standard network. Dante does away with heavy, expensive analog or multicore cabling, replacing it with low-cost, easily-available CAT5e, CAT6 for a simple, lightweight, and economical solution. Dante is easy to set up and compatible with JBL Synthesis Dante enabled amplifiers as well as a wide selection of third-party Dante-enabled audio products. Dante integrates media and control for your entire system over a single, standard IP network. The applications are endless.


JBL has a rich history in professional digital audio processing, with products found in the vast majority of world-class recording studios. This pedigree is evident in the proprietary Logic16 up mixer, which produces astonishing natural three-dimensional sound. Designed by HARMAN® research scientists and engineers, Logic16 provides a listening experience that will make you feel like you are in the concert hall or on the set. This subtlety is achieved without the sense of psycho-acoustic processing or effects. Logic 16 will up-mix any input source from mono up to 15.1, including all Dolby formats.

Luxurious Industrial Design

The modern industrial design exudes luxury. The half-inch thick anodized aluminum fascia with bead blasted accents and solid glass display makes a distinguished statement.

Front panel menu options are served up on full-color OLED display.
