English version
For conversions with 6 filters (currently all of these have a 44.1k input rate):
Filters 1 – 4
are the same as for conversions with 4 filters.
Filter 5
is an asymmetrical design with non-linear phase and no pre-ringing.
Filter 6
is a long filter which has linear phase and pre-ringing.
The
Filter
button has no effect if an input / output rate combination with only 1 filter
choice is selected, or if the Upsampler is not locked to a source.
“I don’t have time to listen to all these filters! Which ones do you suggest?”
Filters are definitely a personal choice, but we suggest the following:
•
44.1kS/s > 48, 96, 192 or 384kS/s - Filter 2 (asymmetrical)
•
44.1kS/s > 88.2, 176.4 or 352.8kS/s or DSD – Filter 5 (asymmetrical)
•
48kS/s > 96 or 192kS/s – Filters 2 or 3
•
88.2kS/s > DSD – Filters 2 or 3
The Upsampler remembers the last filter set for each sample rate conversion.
When the menu is open, the
Filter
button changes to the
◄
button, used to page backwards through
the menu.
When the browser is open, the
Filter
button scrolls up the file list.
Input
Button
Press the
Input
button (G) to change the selected input, the input name in the top left corner of the
display will change.
Inputs which are not connected to an active source do not appear in the list and so
cannot be selected. This is an important change from previous versions.
The
USB2
,
iPod
and
Network
inputs are always selectable.
The source sample rate is automatically detected. The full input sequence is:
…, AES, SPDIF1, SPDIF2, SPDIF3, Toslink, SDIF-2, USB1, USB2, iPod, Network,…
When the menu is open, the
Input
button changes to the
►
button, used to page forwards through the
menu.
When the browser is open, the
Input
button scrolls down the file list.
Output
Button
Use the
Output
button (H) to change the output sample rate, the new rate appears on the right side of
the display. The output sample rate sequence is:
..., 32, 44.1, 48, 88.2, 96, 176.4, 192, 352.8, 384, DSD, 32, ....
The Vivaldi Upsampler does not feature down-sampling combinations (except from
DSD).
Output sample rates that are lower than the input sample rate cannot be selected.
If the input rate changes so that it is higher than the output rate, the output rate will
automatically change to match the input.
When the
DXD Mode
menu page is
On
, 352.8 and 384 are replaced in the sequence by DXD. In this
mode, input data at 44,.1, 88.2, 176.4 or 352.8kS/s or DSD is upsampled to 352.8, while input data at
32, 48, 96, 192 or 384kS/s is upsampled to 384kS/s.
When the browser is open, the
Output
button navigates up to the previous directory (if one exists).
