Using Usb Memory Devices - Roberts Stream 83i User Manual

Using USB memory devices

This section describes how to use your sound system to access and
playback your audio fi les via USB memory devices.
USB memory devices plug into the rectangular slot on the front of the
sound system on the right hand side.
Important: Your sound system is only designed to work with USB fl ash
memory devices. It is not intended to be connected to hard disk drives or
any other type of USB device.
It is possible to use SD or SDHC 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 sound system.
The Stream 83i sound system has been tested with a range of USB
memory devices of up to 120GB capacity. USB memory must use the
FAT or FAT 32 fi ling system in order to operate with the sound system.
Audio formats supported are MP3, WMA, AAC, FLAC and WAV. Not all
variations of all audio formats are supported. Please see the section 'Audio
codecs' on page 98 for further details.
Recommendations:
Unless you have only a few fi les on the USB memory device, do not
place all fi les in the root folder.
The number of items (fi les/sub directories) in any directory should be
less than 2000.
Searching and playback will be more responsive if the number of fi les
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 fi les.
The maximum depth of folder nesting permitted is 8 directory levels
(but playback is only from the currently selected folder).

Cautions:
In order to minimise the risk of damage to your sound 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 fl ash memory devices. The
use of hard disk storage media is not supported.
Playback via USB of fi les stored on MP3 players is not guaranteed.
