7.5 Home Screen – Meters
This screen provides a convenient view of all channel,
mix and FX signal activity.
For optimum performance the loudest signals should
read into the yellow. If any red Peak meter flashes then
reduce the level of that signal to avoid possible
distortion. Increase levels if the meter readings are
consistently low.
The Qu-24 meters screen is shown here. Qu-32
provides two pages of meters. The Qu-16 does not
include Group and Matrix meters.
7.6 Home Screen – RTA
This screen displays a Real Time Analyser (RTA) which
analyses the frequency content of the audio signal
currently being monitored using the PAFL keys.
It splits the frequency into 31 third octave bands from
low 20Hz to high 20kHz, the same frequencies as used
on a graphic equaliser. The dominant ‘Peak Band’
frequency displays in red.
The RTA is a useful tool to help you identify problem
frequencies such as room resonance and feedback.
The iPad Qu-Pad app can also show a display of the
RTA peak band (most dominant frequency).
7.7 Home Screen – Qu-Drive (USB audio)
This opens screens associated with the USB stereo
and multitrack recording:
Note - Use the USB storage device with the Qu mixer
only. Do not use it for other applications.
* Format the hard drive on the Qu mixer before
starting to record. Use the Setup / Utility / Qu-Drive
screen. This clears the drive and sets up the Qu
directory structure.
Qu-Drive Stereo page
– This screen presents
the controls for stereo recording to and playback from
a USB device plugged into the top panel Qu-Drive
port.
The blue Stop buttons light if the USB device is
recognised by the mixer. The controls are disabled if a
USB device is not plugged in or recognised.
Stereo Record
– You can record to a USB
storage device plugged into Qu-Drive:

Format = 48kHz, 24-bit, WAV file

Data rate = 288 KB/sec, maximum 4 hours (4GB)

Qu allocates a file name ‘QU-STnnn.WAV’ where
‘nnn’ increments from 001 to 999 starting at the
highest number +1 it finds on the USB device.
Note – Qu-Drive audio recording and
multitrack playback require the USB
storage device to support high sustained
transfer rates. Not all USB devices will
guarantee flawless performance. To find
out more please refer to the
‘Understanding Qu-Drive and USB’
document in the Qu Knowledgebase on
the Allen & Heath web site.
