Audio Note DAC4.1x Balanced Signature - 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 Signature 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
Signature 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 Signature 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 Signature is now ready for operation!
Bedding in
The DAC4.1x Balanced Signature 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
Signature. 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.
