  • Improved stability on HDMI ARC and Optical inputs when used with Samsung TVs.

To update the amplifier, please do the following:

  1. Disconnect the amplifier from power.
  2. Connect the amplifier to a computer via a USB-A to USB-A cable. Alternatively, use a USB-A to USB-C cable if your computer has a USB-C connector.
  3. While the power is unplugged from the amplifier, press and hold the volume knob on the front of the amplifier. While holding the volume knob, reconnect the power cable to the amplifier.
  4. The amplifier should appear on your computer as a “normal” USB drive, named “CRP DISABLD”.
  5. Open the drive and delete the “firmware.bin” file.
  6. Once deleted, copy the new firmware onto the drive.
  7. Once the firmware is copied, unplug the power and USB cable, wait 30 seconds, and reconnect the power to the amplifier.
  8. Powered on the amplifier, and ensure it’s on the Bluetooth/Streaming input (LED furthest to the left: orange LED on the SA2 and blue LED on the SA1MK2).
  9. Hold the volume knob for 10 seconds. This resets the amplifier. For the SA1MK2, it will take less than a minute; for the SA2, it will take a few minutes. Once it's ready, it will be ready to be set up as new.
