Audio Note DAC Zero Manual

Congratulations on your purchase of the Audio Note DAC ZERO. 

The DAC ZERO is specifically engineered for  sonic performance rather than 

technical specifications.  Although the DAC ZERO 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:  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 generate a fair 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 purposely 

designed audio component support system. 

AFTER CARE 

No special maintenance is required for the DAC ZERO.  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 tubes used in the DAC ZERO should 

provide a useful life span of about 3 years if the DAC is operated on a 12 hours per 

day, daily basis. 

Although replacement tubes for the DAC ZERO are widely available, better 

performance  will be obtained with tubes selected and matched specifically for the
