Using the DAC1.1x 

Once all the connections are complete, turn on the digital source. Next turn on the 
DAC1.1x  by using the rocker switch located on the back panel above mains inlet 
socket. The red led on the front panel confirms that the unit is on. 

The DAC1.1x will improve over time and will start to sound increasingly well 
balanced. This is because of the “bedding in” time taken by new electrical 
components inside the unit. Also, the DAC’s sound quality improves as the unit 
reaches its normal, stable operating temperature. Only a rear panel on/off switch is 
provided as the unit is designed for continuous operation. The DAC1.1x need not be 
switched off each time after use. It is interesting to note that continuous operation not 
only results in optimum sonic performance (since the unit is maintaining a constant 
operating temperature) but also causes less electrical stress and so extends component 
and valve life. 

All our DACs have been designed to run into impedances of 100kOhms or greater. 
Many preamplifiers both active and passive have low input impedances. We do not 
recommend less than 50kOhms as this causes problems with bass roll off. If you are 
in any doubt consult your dealer. Audio Note offer a modification to customers who 
own pre-amplifiers with a low input impedance, which is fully refundable if at any 
time an Audio Note pre-amplifier is purchased as a replacement. 

Cleaning 

Cleaning the DAC1.1x is best done with a soft brush - some photographic stores are 
able to provide suitable brushes. Alternatively, a soft cotton cloth may be used with a 
mild propriety cleaner for removing dirt build-up. Strong or alcohol  based solvents 
may damage the finish of this product. Ensure the DAC1.1x is switched off and cold 
when cleaning. Do not wet the unit. 

Upgrading the DAC1.1x 

One of the main problems with Digital Audio is the limited lifecycle of all but a few 
products. This is why we  make every DAC below the DAC3.1x Signature 
upgradeable to that level. In this way your basic investment is not devalued but 
remains secure for many years to come. If you wish to upgrade your DAC, contact 
your dealer and they will advise you on the best way to go about it.
