Scene, Library and Show memories - Qu-16, Qu-24 and Qu-32 memories
are compatible. Files created on one model can be transferred via USB key
and loaded on the other. The extra features of the bigger models will be
ignored when their file is loaded on a Qu-16. The extra features of the bigger
models will be reset to factory default when a Qu-16 file is loaded.
Note To be compatible, ensure all your Qu mixers are loaded with the same
version of firmware later. Check the Allen & Heath web site for the latest
firmware available.
USB Audio - A USB hard drive formatted on one model can be used on the
other. Stereo and multitrack Qu-Drive recordings are compatible. USB B
audio streaming is compatible, but note that the Qu-16 is 24 out / 22 in, the
Qu-24 is 32 out / 30 in, and the Qu-32 is 32 out / 32 in.
Firmware - Different firmware is needed for each model. Choose either the
Qu-16, Qu-24 or Qu-32 file when downloading firmware from the Allen &
Heath web site. The firmware version number will be the same for each
update that is made available. The procedure for updating firmware is the
same for all models.
