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-
16, Qu-24, Qu-32 or Qu-Pac firmware. The file is packaged
in a .zip archive and its name includes the model and version
number, for example:
Qu16UpdtV1_82_4387.zip.
Save the
file to your computer.
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 file it finds. The firmware file is
in the root directory of the USB device and has a .QUU
extension.
Step3 Extract the .QUU file to the USB root directory
The Qu mixer will look for a valid firmware file in the root
directory of the USB device. Unzip the downloaded file on
the computer and make sure the extracted .QUU file is
placed 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.
during the update. For Qu-16, Qu-24 and Qu-32 models the
screen goes blank and the Pan control indicators flash in
sequence during the update. For the Qu-Pac the SoftKey
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.
You may need to re-calibrate the faders using the
Setup /
Utility / Calibration
screen after the update.
Note
From V1.82 onwards the
firmware files are packaged as .zip
archives.
This affects the firmware update
procedure. Refer to Step 3 below.
