Emotiva Pro Stealth DC-1 Unied Windows USB Drivers: 2013/07/20

Notes: Windows XP
Windows XP works well as an audio server, and may even give you satisfactory results on slow or
underpowered computers. It does, however, have limited audio setup options.
FooBar2000 (a popular free audio player) works well on Windows XP, and we recommend it as an
option in this situation. (FooBar lacks most “pretty” interface options, but offers lots of more technical
options, and is very exible. Although we can’t provide support for FooBar, there are all sorts of
support and discussion groups dedicated to it.)
Also note that, if you do choose to use FooBar2000, FooBar in particular sometimes has an odd
problem in Windows XP. If you play les with different sample rates one after the other, without
closing FooBar between them, sometimes FooBar will switch to the sample rate of the rst le you
play, and then resample all subsequent les to that sample rate. If this happens on your system,
when you want to play a le of a different sample rate, you will have to close and re-open FooBar.
NOTE: The display on the DC-1 ALWAYS displays the actual, physical sample rate of the
audio it is receiving. If what you see on the display disagrees with what you expect to see
based on your settings in Windows, then trust the DC-1’s display
Notes: Windows 7
Windows 7 works well as an audio player, but is slightly more demanding in terms of your computer
hardware. (If you play audio on a PC with Windows 7 and too little memory, or too little processing
power, or too many other programs running, you may experience audio dropouts. This happens
more with certain players than others, and is dependent on the specic combination of hardware
and software in your PC, and on which output mode you choose.)
In specic, WASAPI modes tend to require more resources, and so are more likely to have problems
on older PCs. If your player program offers the option, you may be able to reduce or eliminate these
problems by adjusting your buffer settings. (Neither lower or higher is necessarily “better”, so simply
try until you nd the one that works best on your computer.)
Different players also have wildly differing resource demands, so some players will work well on
almost any machine, while some are very particular, and so difcult to get to run without problems.
NOTE: By default, Windows 7 will use Direct Sound mode (kernel streaming), which will
re-sample any audio les you play to the default sample rate (as set under the Advanced
Properties dialog under Sound Devices in Control Panel). In this case, your player program
will display the sample rate of the actual le, but the DC-1 will display the sample rate of
the audio it receives (the two will be different since Windows is re-sampling the audio);
both are correct. If you don’t want Windows to re-sample your les, you must choose a
player program that supports WASAPI or some other “bit-perfect” mode, and select it in
your player’s conguration. Certain of the C-Media drivers will offer ASIO mode on some
computers; whether this works well on your computer will depend on your player software
(the setup options are rather complicated, and you’ll have to ask your software vendor for
details about how to congure them for optimum performance).
Notes: Windows 8
We have run the current DC-1 driver successfully under Windows 8 (as have several customers
that we know of). Conguration options and requirements will vary depending on your hardware and
Windows software conguration.
