IMPORTANT SAFETY
INSTRUCTIONS
• Read the following instructions carefully. Save all instructions for future reference.
• Follow all warnings and instructions.
• JBL Synthesis expressly forbids unauthorized modification of this equipment.
• Using the unit in the following locations can result in a malfunction:
o In direct sunlight
o Locations of extreme temperature or humidity
o Excessively dusty or dirty locations
o Locations of excessive vibration
o Close to magnetic fields
• Condensation can form on the inside of the apparatus if it is suddenly moved from a cold environment to a
warmer location. Before switching the unit on, it is recommended that the unit be allowed to reach room
temperature.
• Install the SDP-75 on a solid, flat, level surface that is dry, well ventilated and out of direct sunlight. Be sure
that all four feet are supported.
• • Clean only with a dry cloth. Do not use liquid solvent-based cleaners.
• Protect the detachable power cord from being walked on or pinched particularly at plugs, convenience
receptacles, and the point where they exit from the apparatus. If the ac cord becomes damaged, do not use it.
Immediately replace it with a new one of the same or better rating.
• Unplug this apparatus during lightning storms or when unused for long periods of time.
• Do not open the equipment case or remove any of the cover panels. There are no user serviceable parts in this
equipment. Refer all servicing to qualified service personnel;
• To prevent fire or shock hazard, do not allow liquids to spill or objects to fall into any openings of the product.
• Always insert the ac plug into a grounded outlet. Do not remove the ground pin or disable the ground for any
purpose. The main AC has to be protected by a circuit breaker conforming to local standards.
• Before connecting the equipment, check that the main power supply voltage rating corresponds with the local
main power supply. The rating of the main power supply voltage is printed on the equipment.
• If replacement of the ac line fuse and/or any internal fuse becomes necessary, replace only with same value
and type of fuse (110V: T1A Schurter FST 5x20; 220V: T800mA Schurter FST 5x20). Never bypass the fuse.
• It is imperative that the SDP-75 be operated in a well ventilated environment and the immediate external
temperature be maintained as specified. Do not expose the SDP-75 to humidity, steam, smoke or excessive
dampness or dust. Maximum permissible operating conditions: 0°C to 40°C, 20-65% relative humidity. External
cooling fans may be required in some cases.
• Do not stack any equipment directly above or below the SDP-75 as to protect it from overheating, as well as
the continued functionality of any equipment near and around it.
• Do not ingest the remote control battery. The remote control supplied with this product contains a coin battery.
If the button cell battery is swallowed, it can cause severe internal burns in just 2 hours and can lead to death.
Keep new and used batteries away from children. If the battery compartment does not close securely, stop
using the product and keep it away from children. If you think batteries might have been swallowed or placed
inside any part of the body, seek immediate medical attention.

1 INTRODUCTION
The JBL SDP-75 defines the state of-the-art in surround sound processors in terms of sound
quality, seamless "3D" immersive audio, true decoding of up to 32 channels* in Dolby Atmos,
seamless, optimized decoding and processing of all currently-available surround CODECs,
utilizing HARMAN's newest research-based on-board room correction. The SDP-75 is part of
a JBL Synthesis or Revel-based ecosystem, which optimizes numerous parameters based on
easy-to-use drop-down speaker model selections. #
Utilizing an Intel®i7 PC-based platform, only the JBL SDP-75 offers all these features,
as well as a future-resistant on-line update capability that no DSP-based system can match.
64-bit floating point calculations and 24-bit/192kHz native processing assures the highest
sound quality from virtually any source, and without re-clocking, which is the case for virtually
every other surround processor, and which results in a significant sonic compromise.
A user-friendly web-based interface for both setup, calibration and run-time operation
allows remote setup, operation and diagnoses via IP. An exclusive 3D speaker configuration
tool simplifies arraying speaker groups, optimization of speaker functionality based upon
codecs, and convenient channel identification. Internal gigabit Ethernet, and full host Wi-Fi
simplify setup and operation.
*16, 24, and 32-channel versions of the SDP-75 are available.

1.3 JBL SYNTHESIS CERTIFIED INSTALLERS
The JBL SDP-75 surround processor provides an unprecedented degree of flexibility and automation, along with
decoding of every current format and very flexible speaker configuration. All of this results in a superior end-user
experience, with complex operations, such as automatically switching speaker configurations depending upon the
format being transparent to the end-user. The SDP-75 should only be installed and calibrated by a certified JBL
Synthesis Installer.

1.6 THE SOFTWARE
AVAILABLE OPTIONS TO ACCESS THE GRAPHICAL USER
INTERFACE
The SDP-75 offers multiple options to display and control the user interface:
• Directly with a physical display, a mouse and a keyboard connected to the PC connectors of the SDP-75.
• Remotely with a VNC Client over the network, from any computer or tablet to access the full user interface
in order to operate and/or setup the SDP-75.
• Remotely with an internet browser, with a limited access to the user interface allowing to operate the SDP-
75 but without all the setup menus.
The Graphical User Interface of the SDP-75 is specifically designed for touch screen use but it is just
as easy to use with your laptop’s trackpad or with a mouse.

NOTE: The design and the user experience of the SDP-75’s Graphic User Interface are constantly
improved with software updates.
