AYRE QB-9DSD - Manual (Page 5)

Overview and
Introduction
The integration of the personal computer (PC) into
the home stereo system has provided a revolutionary
way to purchase, organize, and play your digital
music collection. The Ayre QB-9
DSD
digital-to-audio (D/A) converter provides an equally
revolutionary way to play back your music files with
unprecedented fidelity and realism.
Connected via the ubiquitous USB port, the
QB-9
DSD generates the master audio clock and
requests the data from the computer at the correct
time for jitter-free playback of your music. Apple
computers can use the standard device driver, while
Windows PCs must install a free download available
from the Ayre website.
The QB-9 DSD also utilizes opto-couplers to provide
total electrical isolation for the connections between
your computer and music system. This minimizes
the introduction of unwanted radio-frequency
interference (RFI), generated by all computers.
Avoiding the use of wireless networks (e.g.,
Wi-Fi), by employing wired connections instead,
will reduce RFI levels in your home and results in
improved sound quality for any music system.
