OPERATION
Press button on front panel for short time to select digital input, USB or COAX.
Selected input will be indicated by red light.
Using the DAC0.1x with dedicated CD transport:
Once all the connections are complete, turn on the digital source. Next turn on the
DAC0.1x 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 DAC0.1x 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 DAC0.1x 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.
Using the DAC0.1x with a PC/MAC computer:
The computer MUST BE PROPERLY GROUNDED.
The USB interface acts as a ‘native’ USB audio device and does not require the
