Question

What is the Utility button for on the back of the amp?

Answer

TC may provide updates for the built-in software of your amplifiers firmware. Updating your TC amp’s firmware requires:

  • a computer running Microsoft Windows or OS X with a standard USB interface
  • a USB cable.

Preparing the firmware update:

Download the newest firmware from the “Support” page for your TC amp. If a firmware update is available, you will find update there

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.
