Why Update Your Harman Kardon BDS 570?

Before diving into the “how,” you must understand the “why.” Many users ignore firmware because their system “works fine.” However, a stale firmware version on the BDS 570 leads to three specific performance bottlenecks: A USB 2

3. Where to Obtain the Firmware

Official Source (Legacy): Harman Kardon’s official product page is no longer actively hosted. The final firmware can sometimes be found via:

Unofficial but reliable sources:

⚠️ Avoid: Random file-sharing sites. Malicious firmware can permanently brick the device.

4. Surround Sound Format Improvements

Some updates added better support for DTS 96/24 and corrected LPCM handling over HDMI ARC (Audio Return Channel). Updating ensures you are getting the correct channel mapping for 5.1 surround soundtracks.

What If There Is No Official Firmware Update Available?

Harman Kardon officially exited the HTIB market years ago, and their support for legacy products like the BDS 570 has largely evaporated. If you cannot find the firmware file anywhere (forums, archive.org, or torrents), you have three options:

  1. Live with the bugs. Many BDS 570 units run indefinitely on v1.0 firmware. The biggest risk is HDMI incompatibility with modern 4K TVs. A workaround is using optical audio out instead of HDMI ARC.
  2. Replace the main board. You can find used BDS 570 mainboards on eBay that may have a newer firmware pre-installed. Look for service stickers indicating “FW updated.”
  3. Upgrade your system. As painful as it sounds, the BDS 570 is limited to 1080p and DVD/Blu-ray (the 570 is actually a DVD changer, not a Blu-ray changer – note that some BDS models are Blu-ray, but the 570 is DVD only). If you need modern format support (4K, Dolby Vision, Atmos), it might be time to retire the BDS 570 to a secondary bedroom system.
