Congratulations on your purchase of the Audio Note™ DAC One.1x.
The DAC One.1x was specifically designed and engineered for the best sonic

performance rather than technical specifications. Although the DAC One.1x is a
digital component (there is no avoiding this unfortunately!), it will bring a new level of
musicality to your CD’s and is fatigue free during extended listening periods. In order
to obtain the best possible performance and longevity from your DAC, please read
over this manual carefully.

Technology: The DAC One.1x uses the revolutionary and currently exclusive Audio
Note™ digital technology which we have the 1xoversampling™ direct from disc™
circuit topology. The ultimate version of this technology is found in the extremely
expensive DAC5Signature, and we have taken great to ensure that as much of the
inherent advantages of the topology have been retained in the sound of the DAC
One.1x. The technology dispenses with all the correction measures inherent in all
other d-a converters and presents the digital signal directly to the converter after
reformatting. This allow you to hear what is actually recorded on each disc, rather
than, as has been the case up to now, some technically and cosmetically altered
version, as a result the reproduction is more reminiscent of a master tape in quality.

Not surprisingly for an Audio Note™ product, the DAC uses vacuum tube technology,
implemented using traditional Audio Note techniques.

UNPACKING & INSTALLATION.

Please take care when unpacking the DAC. We recommend that you store the
packing materials in case the unit requires shipping at a later date.

Next, select a suitable location for the unit, ensuring that adequate ventilation is
provided (the vacuum tubes do generate some amount of heat). In the interest of
safe, reliable operation, situate the DAC away from dampness or direct sunshine.

Worthwhile sonic improvements may be obtained by locating the unit on a suitably
designed audio component support system.

AFTER CARE
No special maintenance is required for the DAC One.1x. Cleaning is best made with

a soft cloth or brush similar to those sold by photographic stores for lens cleaning
applications.

Use a cloth dampened with mildly warm water and a weak soap solution for removing
grease or oily substances. Strong or alcohol based solvents may cause damage to
the DAC’s finish.

Replacing the vacuum tubes. The vacuum tube used in the DAC One.1x is a sub
miniature triode called the 6111WA, it is wire ended and soldered directly into the
PCB. The 6111WA should provide a useful life span of about 10 years if the DAC is
operated 24 hours per day, which is the recommended operation and the one that
sounds the best.

Although replacement tubes for the DAC One.1x are fairly widely available, better
performance will be obtained with tubes selected and matched specifically for the
DAC by Audio Note. Should the vacuum tubes require replacement, please contact
your Audio Note dealer for technical support.
