Once connected to the network, follow these instructions in order to fully and successfully install the Cinema 1200 firmware. You will first manually install the MCU and WIFI firmware, and the DSP portion of the update will happen automatically within 48 hours of the manual update.
To find your firmware versions, tap – do not hold – the PAIR button on the right side of the bar.
- DSP 4.4 or higher
- MCU 92 or higher
If the bar does not meet these requirements, DO NOT ATTEMPT UPDATE. Please instead use this article to update - Cinema 1200 - Updating Older Firmware.
USB Flash Drive Formatting Instructions
You will need to format the flash drive before your product can read from it. If you already know how to format a flash drive for FAT32, feel free to skip this step.
IMPORTANT: Use a flash drive that doesn’t store any important information. This process will wipe the contents of the drive.
- Delete all existing files from a USB flash drive.
- Make sure drive is 8GB or less and formatted to FAT32
- Follow this link to download the SWU file to the flash drive.
- Unzip the folder, (if needed), and rename the downloaded file "image.swu" (without the quotes).
- Move the renamed file to the formatted flash drive.
- Eject the flash drive from your machine. Macs require you to drag to the Trash or click the eject icon in Finder. In Windows, you right-click the flash drive and select Eject.
- Power on your soundbar if it's not on already
- Remove the side panel to expose the USB slot on the soundbar
- Plug the flash drive into your soundbar
- Hold the Power button on the soundbar until the word UPGRADE appears, then release the Power button
- The words "UP WIFI" will appear and quickly disappear - THE UPDATE IS NOT COMPLETE
- Wait about 2 minutes for the update to begin - it must copy the very large update file to the bar, and it shows no indicator while this is occurring. DO NOT REMOVE FLASH DRIVE.
- You will see the update count from "00" to "100"
Wait for the upgrade to complete - the display should revert back to "TV 30"
- It can be a good idea to wait 10-20 minutes, in case the software is upgrading and not showing status updates, which has been the case in earlier versions of the software. It may also flash SUR RX, SUR TX, MCU, and other items during the update.
- In some cases, the LED display may go blank after the update completes. In those cases, simply press the "LED" button on the included remote to turn the LED's back on.
- Remove the flash drive
- Unplug the soundbar, wait 10 seconds, and plug it back in
- Power on the soundbar
- Scroll through the versions of installed software to confirm the update has completed. WIFI version should be 126.96.36.199.
At this point, the manual process of the update is complete. However, your MCU and DSP values will take some time to automatically update. If the bar has not updated automatically within 72 hours, please reach out to Klipsch Product Support for direct assistance - How To Contact Us for Support
Note: You can check the various, current firmware version numbers by pressing the small surround pairing button under the right end-cap.
Keep pressing this button to scroll through all the firmware currently active on your device. It should display as follows:

WIFI 188.8.131.52 >
