Sound Optimization - Lindemann Limetree network Mode D'emploi

GETTING STARTED
USB operation
The Limetree NETWORK can play music
USB
from USB storage media such as USB sticks
or harddisks. For this purpose the device is equipped with a USB
host connector on the rear side.
The USB memory can be formatted in one of the following file
systems: FAT16, FAT32, NTFS, ext2, ext3 or ext4. The storage
medium can also be fed via the USB connector of the Limetree
NETWORK, provided the current draw of the device does not ex-
ceed 1.5 A. Thus standard 2.5" USB harddisks can be connect-
ed directly without the need for a separate power supply. The
USB host port may also be used for charging smartphones.
A special feature is the possibility to run an external CD/DVD-ROM
drive (e.g. Apple Superdrive) on this connection: after docking the
drive, a CD playback menu will pop up in the app which allows to
use the Limetree NETWORK as a CD player.
SOUND OPTIMIZATION BY DSD
RE-SAMPLING
DSD-Re-Sampling
The Limetree NETWORK uses a sophisticated
technology for improving the sound quality, the
so-called DSD mode. To activate it, simply press and hold the
toggle switch of the device for three seconds in the upper
position. The LED indicator will light up yellow.
In DSD mode all PCM data are converted into a high-resolution
1-bit signal, the so-called DSD (Direct Stream Digital). With
DSD re-sampling the converters act as a pure filter circuit
without DSP influence. Soundwise this 1-bit mode is more
transparent and more natural than the PCM operation.
When the DSD mode is inactive, the network player uses an
intelligent re-sampling and synchronizes the digital data by
means of an ultra-precise FemtoClock to eliminate any im-
pact by the clock jitter on the sound. The input data are trans-
ferred "bit-perfect" to the converters.
