Before you begin, you will need a computer with Ethernet capability and Universal Control version 3.2 or later installed. Universal Control can be downloaded from your My PreSonus account. Make sure that only your NSB stage box and your computer are connected to the network. Only one PreSonus AVB Ecoystem device can be updated at a time.

1. Log into My PreSonus.com.
2. Click on "My Products" to show your registered PreSonus products.
3. Click on "Hardware" to display every hardware product that you have registered.
4. Click on the NSB stage box that you would like to update.
5. Click on "Get Latest Firmware."
6. From the instructional pop-up window, click "Download NSB Fimware" (Note: NSB model and Firmware version will vary).
7. Once the firmware file has downloaded to your computer, open the .zip file:

8. Connect an Ethernet cable from your computer to your NSB stage box. No other PreSonus AVB devices should be connected to your NSB during the firmware update.
9. Open Universal Control and click on your NSB stage box . Your NSB stage box should be the only PreSonus AVB Ecosystem device displayed in the Universal Control Launch Window. A yellow dot will indicate that your firmware is out of date.
