Record/Playback Priority
Stereo USB playback signal will be sent to the dedicated stereo USB Input channel
and will take priority over signal from USB-B. When stereo recording/playback is in
progress, it is not possible to use SD record/playback or store/recall data from
USB storage.
Folders, files and formats
The USB device must be formatted to FAT32. This can be carried out using a
computer, but it is best to format a drive using the CQ before use.
Format connected storage in the HOME / SYSTEM / USB and SD (symbols) screen.
Recordings are made to the AHCQ\USBREC folder.
Stereo recordings are made to stereo interleaved 24bit uncompressed *.WAV files,
at the sample rate set in the CONFIG / USB/SD/BT / USB/SD screen.
The CQ can playback stereo files that were recorded on the CQ, or mono/stereo,
44.1/48/96kHz, 16/24bit *.WAV files from the AHCQ\USBREC folder.
Buffer Usage
Buffer usage meters indicate the performance of the connected storage device. If
buffers are filled, data will be lost and an error will be counted.
Length of recording
The maximum length of a stereo recording is determined by the maximum file size
of 4GB, which equates to approximately 2 hrs at 96kHz or 4 hrs at 48kHz.
