Mastertunings

How to Update Mastertuning on Your C8 Speakers:


  1. If you are not using the included USB stick, format your USB stick to FAT32.
    (If you are unsure what this means, search YouTube for "how to format a USB stick to FAT32." It’s a quick and simple process.)
  2. Download the desired Mastertuning file and copy it to the USB stick.
  • Ensure there is only one Mastertuning file on the USB stick at a time.
  • If you want to try a different file, delete the previous Mastertuning file before copying a new one.


  1. Turn off the speaker and insert the USB stick into the USB port on the back of the speaker.
  2. Turn on the speaker while the USB stick is inserted.
  3. The LED lights on the back of the speaker should perform a quick circular motion, indicating that the Mastertuning has been installed successfully.
  4. Remove the USB stick and repeat step 4 on the second speaker.


Note:

  • If the LED lights move slowly in a circular motion, it means the Mastertuning was not installed correctly. This is likely because the speaker cannot read the USB stick.
  • Check if the USB stick is formatted to FAT32 and try again.
  • If the installation still fails, try holding the pairing button while turning on the speaker with the USB stick inserted.
  • If this doesn’t work, the speaker may not accept your USB stick. Try using a different USB stick.
