OWNERS MANUAL FOR WEISS DAC202 D/A CONVERTER

Particularly the sampling rate conversion can creep in
“unnoticed”. I.e. the sampling rate in the Weiss Firewire IO
window has to match the sampling rate of the file played; else a
conversion is going on in the operating system. For iTunes there
is another thing to know: Whenever the sampling rate is
changed in the AudioMidi setup or the Weiss Firewire IO
window, the iTunes program has to be restarted to gain bit
transparency again. For iTunes running on a Mac computer a
program like Sonic Studio’s “Amarra” is highly recommended.
With Amarra it is possible to switch the sampling rate in
AudioMidi (i.e. in the DAC202) automatically depending on the
sampling rate of the file played. Amarra works in conjunction
with iTunes.
On a Windows based system the use of ASIO or WASAPI is
highly recommended. These systems make it simple to achieve
bit transparent playback. In addition the sampling rate of the
DAC202 is switched automatically depending on the sampling
rate of the file played. Note that the test audio files do not
generate any audible audio signal. This makes sure that your
speakers are protected when doing the test.
