8.17 Utility – Firmware Update
The Qu mixer operating firmware can be easily
updated using a USB device (key or drive).
Make sure the USB device has
been previously checked and
formatted to work with the Qu
mixer.
If you need to format the device
then use the Format facility in
the Setup / Utility / Qu-Drive
screen.
Step1 Download the firmware
Visit the Allen & Heath web site and download the
latest Qu firmware. Choose the firmware for your Qu
mixer model. The file has a .QUU extension and a
name that includes the model and version number.
Save the file to your computer. For example:
Qu16UpdtV1_23_4567.QUU
Read the Release Notes available on the download
page.
Step2 Remove previous Qu Firmware from USB
It is important to remove previous firmware files as the
Qu will attempt to load the first version it finds. The
firmware file is in the root directory of the USB device
and has a .QUU extension.
Step3 Copy the file to the USB root directory
The Qu mixer will look for a valid firmware file in the
root directory of the device.
Step4 Run the Firmware Update
Plug the USB device into the Qu-Drive port.
Open the Setup / Utility / Firmware screen. If valid
firmware is found its version number will be displayed
on the screen. For example:
Touch the Update button. The update will start
immediately. The screen goes blank and the Pan
control indicators flash in sequence while the update is
running. After a few minutes the mixer will reboot.
Important note Do not remove power during the
firmware update. Do not remove the USB device until
the update has completed.
The mixer restarts automatically after the firmware
update.
