![]() ![]() We recommend you use the USB hard drive for the Qu mixer only. Maximum USB drive size (FAT32 file system limit) is 2TB. The smallest USB drive size that should be used with Qu-Drive is 2GB. This is not obvious when looking at drives and you will need to consult the manufacturer’s data ![]() Only drives that communicate over USB Attached SCSI are supported. SCSI drives - hard drives using the SCSI command protocol ATAPI are not supported.HDD drives - magnetic drives are generally suitable for recording but can suffer from physical disturbances such as vibration due to low frequency exposure, which can throw the head off-track and cause a delay while the actuator repositions it, eventually impacting on the input/output performance.SSD drives - generally suitable for recording but can be prone to performance degradation over time, also some forms of wear levelling and 'garbage collection' algorithms can cause write speeds to become reduced during recording.USB flash 'key', 'stick', or 'thumb drive' - most keys on the market are not fast enough for multitrack recording.Please refer to the following guidelines for sourcing a suitable USB device. Note that the buffer size in Qu-Drive was improved in firmware V1.4, however dropouts can still occur for a number of reasons. Not all USB devices will guarantee flawless performance - when a USB device causes a pause that is longer than the buffer time in the mixer, a dropout will occur, and data is lost. Qu-Drive audio recording and multitrack playback require the USB storage device to support high sustained transfer rates. The recording format is WAV 48kHz 24-bit. Qu-Drive is a facility to record and playback stereo (2-track) and multitrack (18-track) audio. ![]()
