another until all of the linked components have
been connected.
When connecting the linked
components to form a chain, be careful
not to connect the two ends of the
chain. Closing the chain to form a loop
will cause the AyreLink system not to
function.
AC Power
The QB-9 DSD may be plugged directly into an
unswitched wall outlet. Although proprietary RFI
(radio-frequency interference) filtering is built into
the USB D/A converter, in some situations an AC
power-line filter (such as those offered by Ayre) may
provide additional sonic benefits.
As virtually all computers use switch-mode power
supplies that introduce unwanted RFI on the AC
power line, it may be beneficial to use an AC power
line filter for the computer and its accessories (e.g.,
display monitor), many of which also utilize
switch-mode power supplies.
Break-In
100 to 500 hours of music
played through the system will
ensure full break-in.
Due to the manufacturing processes used for the
printed circuit boards, wires, and capacitors, a
break-in period is necessary for the USB D/A
converter to reach its full performance potential.
