Operation with a computer via the USB is the is the primary purpose of the PureDAC and thus requires
special attention. The PureDAC supports the USB2.0 audio standard, which allows PCM signal transmission
up to 32-bit / 384kHz. However, the player software as well as the operating system’s driver software may in
many cases not support this entire range of options. As a general rule all signals from 16bit / 44.1kHz up to
24bit / 192kHz will work well.
Ü
Most player software displays the type of file and its resolution. If the file information shows a different
display than the PureDAC your computer is re-sampling the signal.
Ü
The term “Bit-Perfect” transmission of the audio data to the DAC was coined to explain than no
manipulation at all is being applied to the audio signal. As this term is sometimes incorrectly used for
marketing purposes, B.M.C. provides you information about recommended applications on-line. Some
simple rules that increase the likelihood of a bit-perfect playback are:
Ü
Make certain that any DSP effects, such as equalizer, reverb, room-simulations. etc., are
disabled
Ü
Software volume control has no effect on the volume of the output signal.
Ü
The sampling frequency display is always in accordance to the original file sampling frequency.
The resolution and sampling frequency depend on the audio file played.
Re-sampling an audio signal downgrades the sound quality significantly.
