For Microsoft Windows (these are ZIP archives containing the firmware installer) and for OS X (these are disk image files containing the firmware installer).

  1. Connect your TC amp to your computer using a USB cable.
  2. Power up the amplifier while pressing and holding the UTIL button on the rear panel.
  3. After a few seconds, you should see the LED next to the UTIL button turn red.
  4. Launch the firmware updater you have downloaded and follow the on-screen instructions to apply the firmware update.
