Overview

This software release is for JBL Synthesis SDR-35 and SDP-55 with the factory fitted HDMI 2.0 board installed. If your SDR-35 or SDP-55 includes the HDMI 2.1 upgrade board, please do not use this software. Instead, please use the latest HDMI 2.1 software release from https://www.jblsynthesis.com/.
Important Notes:

1. Download the Unit software here: https://harman.widen.net/s/vr6ncrbfcv/jbl_sdr35_sdp55_hdmi2.0_1v60_1586
2. If using DANTE, please ensure that the DANTE firmware is also up to date. Check the appropriate product pages at https://www.jblsynthesis.com/ to download the latest version.

Upgrading Firmware

If updating from HOST 0.82 NET 239 (or lower) contact support at luxurysupport@harman.com for assistance
USB update procedure (Host and Net):

1. Confirm the current software version installed by pressing and holding the “MENU” button on the front panel for 5 seconds. Scroll through the options checking HOST and NET versions comparing them to the latest release versions.
2. Once you have confirmed the current installed versions exit the engineering menu. If an update is required, locate the Unit Software files you download from our website on your computer, unzip the folder (In windows right click the folder and select “Extract All”)
3. Once you have extracted the files copy the files ending in “.SWU” & “.FW” on to a freshly FAT32 formatted, empty USB Thumb Drive. After the Copying process is finished, safely eject the USB Drive before disconnecting.
4. Turn on your AVR, making sure it is fully booted (> 40 Sec).
5. Insert the USB Stick in to the AVR.
6. Press & Hold INFO & DISPLAY simultaneously till the HOST Update process starts. This update will take around 20 minutes.
7. Upon completion, the AVR will reboot and then prompt you to press “OK” to reset all settings or press “DIRECT” to skip the reset:
   • If software before update was lower than HOST v1.44 – press “OK” to reset. All user settings and configuration data will be cleared. Dirac calibrations will need reloading on to the unit after the reset. Restoring settings from a USB  or secure backup is NOT recommended for the same reason a reset is required.
   • If software before update was greater than HOST v1.44, either “OK” to reset, or “DIRECT” to not reset. All settings will be retained when pressing “DIRECT”.

Alternative Update Method: Automatic Over-the-AIR Update
Now that your AVR is up to date via a USB update, and set up within Google Home, you can enable the Auto-Net-Update feature.

1. Go to MENU > HDMI SETTINGS > HDMI Bypass & IP = HDMI & IP ON
   This Setting will prevent the Unit from entering the “low power standby” and will keep the NET Part of the AVR active.
   Once an update is released, your AVR will automatically download and install the NET update overnight.

2. You will be notified next time you start the AVR that an update is available. To manually start a HOST update after an automatic overnight NET update, go to the engineering menu and select “Check for Update” the HOST will now update.
   This will take 75 minutes to complete.

3. Upon completion, the AVR will reboot and then prompt you to press “OK” to reset all settings or press “DIRECT” to skip the reset:
   • If software before update was lower than HOST v1.44 – press “OK” to reset. All user settings and configuration data will be cleared. Dirac calibrations will need reloading on to the unit after the reset. Restoring settings from a USB  or secure backup is NOT recommended for the same reason a reset is required.
   • If software before update was greater than HOST v1.44, either “OK” to reset, or “DIRECT” to not reset. All settings will be retained when pressing “DIRECT”.
