Audio Note DAC4.1x Balanced - Manual (Page 12)

OPERATION
Once all the connections are completed and checked, ensure that the volume control
on your preamplifier / integrated amplifier is at the minimum setting.
Ensure that the CD Transport connected to the DAC4.1x Balanced is switched
ON. Source components should always be the FIRST components to be switched on
and the LAST components to be switched off.
Ensure that all pre and power amplifiers connected to the DAC4.1x Balanced
are switched OFF.
The above procedure minimizes the possibility of loud noises produced by
components at switch on being passed to the loudspeakers and possibly causing
damage.
Turn on the DAC4.1x Balanced by using the rocker switch located on the rear panel,
above the mains inlet IEC socket. The red ‘power on’ indicator LED located on the
front panel should now be illuminated.
Turn on your pre amplifier / power amplifier / integrated amplifier. If you are using a
pre / power combination, always turn on the pre amplifier BEFORE the power
amplifier(s).
The DAC4.1x Balanced is now ready for operation!
Bedding in
The DAC4.1x Balanced requires around 200 hours of initial use
(called “bedding in”) before the circuitry becomes stable and
optimum performance is realized. As the device “beds in” the
sound will become increasingly more smooth, detailed and
open. A warm up time of approximately 30 minutes is required
each time the device is switched on before optimum sonic
performance is reached.
Cleaning
No special maintenance is required for the DAC4.1x Balanced.
Use a soft, clean lint free cloth to remove any surface marks
from the casework. For finger marks / grease, use a soft, clean
lint free cloth, lightly moistened with a solution of warm water
and mild detergent. Do not use any alcohol or solvent based
cleaning products, as they may damage the finish.
ENSURE THAT THE DEVICE IS SWITCHED OFF AND
DISCONNECTED
FROM THE MAINS ELECTRICITY
SUPPLY BEFORE UNDERTAKING ANY CLEANING.

The valves supplied with your DAC4.1x Balanced should
provide approximately 5 years of operation. They are specially
selected by us, and should only be replaced with valves of the
same type and specification. Please consult your Audio Note
