GENERAL
Congratulations on your purchase of the Audio Note CD Zero CD player.
Audio Note is highly critical of the digital medium as presented by compact disc; we
sincerely hope that you too will find this player breaks free from the 'digital mould' that we
are all so accustomed to, and so open a new window on your CD collection.
Please read over this manual carefully in order to obtain the best possible performance
and longevity from your CD player.
UNPACKING & INSTALLATION
Please take care when unpacking the CD Zero . 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, for example, a dry and dust-free area which
is not exposed to direct sunlight.
Connections:
Connectors on the back of CD Zero unit provide digital and analogue outputs.
Analogue Outputs:
These are the audio signal outputs; one RCA socket is provided per channel. Each socket
is colour coded, with black indicating the left audio channel and red indicating the right
channel. Connect these outputs to your amplifier’s line inputs. The CD player's analogue
outputs may be connected to any line input (such as CD, Aux or Tuner) on your amplifier.
For the best results, we recommend the use of a specifically designed audio cable for
connection between the amplifier and the CD player. Your dealer can advise on suitable type
and quality of cable eg: - Audio Note AN-C is an excellent choice.
Digital Output:
A single RCA connector provides a digital output. The digital output is normally disused,
however, this connector will be necessary should you wish to connect a separate Digital to
Analogue converter, or digital recording/processing equipment to your system.
Mains connector: An IEC power connector is available for connection to the local mains
using the supplied mains cable.
Mains switch is located on the back of the CD Zero just above the mains socket and
turns the unit ON / OFF.
New CD player's sonic performance will start to improve as the internal parts 'bed' in.
The CD player requires about two hundred hours of operation before the bedding in process is
complete.
