Samplerate and filter setting
By pressing the
FILTER
button (5) once or several times you can choose between available
sample rates and filter setttings for a specified source (CD or digital input). The currently
selected sample rate is displayed at the bottom left corner (44.1, 48, 88.2, 96, 176.4, 192,
352, 384 kHz).
NAT
(NATIVE)
indicates that the incoming sample rate of the signal is being
directly processed.
CONV (CONVERSION)
however indicates an ongoing upsampling
process of the incoming signal to a desired sample rate.
Please note that only the settings
NAT / STEEP
or
NAT / SMOOTH
are available if
USB
is
selected.
The digital filter settings
SMOOTH
and
STEEP
can be set according to your personal
preference. Technically speaking, the setting
SHARP
indicates a steep filter characteristic at
the upper end of the frequency band, leading both to a flat amplitude frequency response
and a rather strong phase rotation.
SMOOTH
however leads to a less steep filter
characteristic by showing a slightly earlier attenuation of the amplitude frequency response
with almost no phase rotation.
Please note that a chosen filter setting is only true for a selected input and is being recalled
every time you select the respective input again, even after the device has completey been
switched off.

USB B digital input
If a digital signal from a computer (PC or Mac) is connected to the USB B digital input of your
Media Player (22), you can choose between two different modes (
LO RES
or
HI RES
) by
pressing the
PROG
button (4).
LO RES
can be used to play back a digital input signal with a sample rate of up to 96kHz
without the need for an additional audio driver on your Windows PC or Mac.
HI RES
can be used to play back a digital input signal with a sample rate of up to 384kHz/24
Bit (PCM) without the need to install an audio driver on your Mac. If you are using a Windows
PC you will need to install an additional driver which is available for download on the
respective product page at
.
Below the
LO RES
and
HI RES
indication, the currently active data format is shown on the
display (
PCM
or
DSD
).
Please note that you need to select the
HI RES
mode in order to play back DSD64 or
DSD128 files.
