Home Screen – Qu-Drive (USB audio)
This opens screens associated with the USB stereo
and multitrack recording:
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 1 it finds on the USB device.
Patch the source to be recorded using the
Setup /
Output Patch / USB Audio
screen. Touch the track 17
box and turn the rotary to select the left source. Press
the ‘+1’
Fn
key to increment the right source to track
18, or use the rotary to select an unrelated source.
Mono or stereo Channels and Groups can be globally
sourced from their Insert Sends (pre-processing) or
from Direct Out using this button.
Qu-Drive Stereo recording shares the same patch
as Track 17-18 of the Qu-Drive multitrack recording
and USB streaming.
The record meter on the USB page displays the
current source. The default is LR post-fade.
Arm the recording by touching the red circle Record
button. Touch the Play button to start the recording.
Recording Errors - A warning message displays if
buffer overrun errors are detected during recording.
Try reformatting or using a different USB drive.
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.
