We have tested this interface with several common formats running on Windows™ 8.1,
Windows™ 7, Windows™ Vista (SP2), Windows™ XP (SP3) and Apple Mac™ OSX
10.5 - 10.10 with various PCM streaming programs but we cannot accept responsibility
for correct operation with all source devices, operating systems or software.
The
Settings > USB Class
menu page can set the interface to
Class 1
(up to 96kS/s
without a special driver) or
Class 2
(up to 384kS/s, no driver is required for OSX 10.6.3
onwards, the
dCS
USB Class 2 driver is required for Windows).
Operation at 352.8 or 384kS/s on Windows PCs requires the 2014 version of the
dCS
USB Class 2 Driver. If you have updated your Upsampler software from v1.0x, un-install
any earlier version of the Driver from your Windows PC, download the updated Driver
from
http://www.dcsltd.co.uk/products/vivaldi-upsampler/
and install it.
The
USB2
interface (W) on an ‘A’ type connector can stream PCM music files in most popular formats
at up to 24 bits / 192kS/s from a USB Flash Drive. With a Flash Drive connected, a basic browser (see
page
17
) navigates to the music files and selects the file to be played. After closing the browser, the
name of the file is displayed, with a Play or Pause icon and the elapsed playing time.
Mains-powered USB hard disk drives in FAT16 or FAT32 format may be used in the same way. The
interface will not read drives in NTFS format or other formats.
The
USB2
interface will also accept PCM music files up to 24 bits at 44.1 or 48kS/s streamed from an
iPod or iPhone. Note that metadata is not displayed.
