how i will update from version 1.90 to the latest firmware 1.95

i need to update 3 qu 16 consoles,2 of them having version 1.90 and other one having version 1.13…i need to update these mixers…can anyone help me with this?

See this guide for firmware update on the Qu mixers: How-to-Update-Qu-Firmware_5.pdf

My current version is 1.90 & when i try to update to 1.95 its not reading the file from the usb drive

Try formatting the drive in the qu first then copy the firmware onto the drive.

… and if that doesn’t work try a different kind of USB stick. A&H mixer’s are very picky about their USB.
