Firmware Update Procedure

To upgrade your device from unIFY Control Panel, launch Smart Firmware Update from the Tools menu.

  1. Be sure you have downloaded the latest firmware version from the device list below.
  2. Click on the Select File button and locate the firmware package (.SFU file) on your computer.
  3. Once the desired file has been selected, the application will search for the devices that match the selected firmware package, and will also determine the relevant features that require updates on the device.

*Note: If either Dante™ lock or the parameter lock are active, the device will show up with a padlock next to it and the progress bar will be replaced by text indicating the device has an active lock. No updates will be possible in this device until the lock is removed.

To initiate an update, check the device or devices in the list with their associated checkbox and click on the Start button.

For further configuration assistance, download the unIFY User Manual for your product.
