6 Anedio D1 DAC
Extravagant interconnects with exotic materials are unnecessary.
Two characteristics, however, are important: (a) low shield (outer
conductor) resistance; (b) robust mechanical design for reliable
electrical contact. The shorter the cable, the more transparent your
system will be.
Plug-and-Play USB Interface
The D1 DAC is a plug-and-play USB device. There is no need to
install a USB driver. Simply plug the USB input of the DAC into the
USB port of a computer, and you can enjoy listening to music
immediately.
Connecting Power Cord
For the lowest ground noise and hum, it is highly recommended that
the power cords of all components be connected to a single point —
usually a single surge protector with multiple outlets. This keeps all
components referenced to a single point, as far as it is practically
possible, thus minimizing the differences in ground potentials
among the components.
Never use a 3-prong-to-2-prong adapter to fix a ground loop
problem. This will disable the safety earth ground and may
cause electric shocks.
Isolating Cable TV Ground
If you have a cable TV connected to your audio system, ensure that
the cable ground is galvanically isolated from the audio ground. The
cable TV ground, tied to the earth outside your home, is at a
significantly different potential and can cause audible hum if it is
not isolated properly. If you suspect this is the case, insert a cable
TV ground isolator inside your home, just before your cable set-top
box or TV RF input.
Surge Protectors
A surge protector is strongly recommended so that the components
are protected from large power lines spikes, which can occur, for
instance, from lightning strikes.
Power Switch
The power switch is located in the back panel. Toggle the switch to
