UNPACKING & INSTALLATION.
Please take care when unpacking the CDT 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:
The transport’s sonic performance will start to improve as the internal parts ‘bed’ in.
The transport requires about two hundred hours of operation before the bedding in
process is complete.
A single connector provides a digital output for connection to your DAC via your digital
input RCA connector. Your dealer can advise on suitable type and quality of cable
eg:-Audio Note is a excellent choice.
Power connector: An IEC power connector is available for connection to the local
supply. Simply connect this to a convenient power point using the supplied cable.
IMPORTANT INFORMATION
Compact disc transports have built-in error compensation circuits to correct minor
manufacturing defects on a disc. In some cases, defects on the disc, which are too
large for the error compensation circuits to handle, may cause the CD player to skip
some tracks during playback. If this problem occurs, play a new disc, normal
playback of the new disc indicates that the previous disc is damaged in some way.
However, if the problem continues, it is best to have the unit serviced.
