Using USB memory devices
This section describes how to use your audio system to access and playback
your audio files via USB memory devices. USB memory devices plug into the
rectangular slot on the rear of your audio system.
Important:
Your audio system is only designed to work with USB flash memory
devices. It is not intended to be connected to hard disk drives or any other
type of USB device.
The Stream 67 has been tested with a range of USB memory devices of up
to 256GB capacity. USB memory must use the FAT or FAT 32 filing system in
order to operate with your audio system. Your audio system is unable to play
from media formatted using the exFAT or NTFS formats.
It is possible to use SD, SDHC or SDXC cards for media storage and playback
when held in a suitable USB adaptor. However, due to the wide variation of such
adaptors, it is not possible to guarantee that all adaptor / card combinations
will work in the audio system.
Audio formats supported are MP3, WMA, AAC, FLAC, ALAC and WAV.
USB playback does not support files encoded using WMA Lossless, WMA
Voice, WMA 10 Professional, nor files of any format which have DRM protection.
Recommendations:
Unless you have only a few files on the USB memory device, do not place
all files in the root folder.
The number of items (files / sub-folders) in any folder should be less than
2000.
Searching and playback will be more responsive if the number of files in
any one folder is limited (we suggest not more than 250).
It is recommended that the USB memory is reformatted in your computer
before adding your music files.
The maximum depth of folder nesting permitted is 8 folder levels (but
playback is only from the currently selected level).
Shuffle and Playlist functions are limited to 500 tracks.
Cautions:
In order to minimise the risk of damage to your audio system
or your USB memory, please place the unit so that the memory
device cannot easily be knocked while it is inserted in the socket.
Remove the USB memory before carrying the unit or if not using
the USB feature for a prolonged period.
Place the unit in Standby mode before removing your USB
memory device.
The USB connection is intended only for flash memory devices.
The use of hard disk storage media is not supported.
Playback via USB of files stored on MP3 players is not
guaranteed.
