Using USB memory devices
This section describes how to use your multi-room adaptor to access and playback your audio
fi
les from USB memory devices. USB memory devices
plug into the rectangular slot on the back of the adaptor.
Important: Your adaptor 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.
Cautions:
In order to minimise the risk of damage to your adaptor 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.
Aux In
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-folders) in any folder 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 folder levels (but
playback is only from the currently selected level).
Shuf
fl
e functions are limited to 500 tracks.
The RS1 adaptor has been tested with a range of USB memory devices
of up to 128GB capacity. USB memory must use the FAT 16 or FAT 32
fi
ling system in order to operate with your adaptor. Your adaptor 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 adaptor.
Audio formats supported are MP3, WMA, AAC, FLAC, ALAC and WAV.
USB playback does not support
fi
les encoded using WMA Lossless,
WMA Voice, WMA 10 Professional, nor
fi
les of any format which have
DRM protection.
