If you would like to see a quick video guide on this please view the video below. Or read the guide further down the page: In order to update the firmware on your X Air mixer you first need to download the X Air edit software and the Firmware file itself. These can be found on the Downloads section of the products page on our website: http://www.behringer.com/EN/Products/XR18.aspx Once you have both downloaded open the X air edit application and connect your X Air Mixer to your computer using an Ethernet cable. In the Setup Page click on the Update FW button. This brings up a file directory so you can select and open the firmware file. Once you open the firmware file the X AIR edit app will automatically update your unit.
