OTHER THAN THOSE SPECIFIED HEREIN MAY RESULT IN HAZARDOUS
RADIATION EXPOSURE.
▷
IF THIS APPLIANCE SEEMS TO BE MALFUNCTIONING, CONTACT A QUALIFIED
SERVICE STATION. DISCONTINUE USE OF ANY MALFUCTIONING UNIT.
Unpacking and Installation
This section describes the unpacking and installation procedures for your new component.
❶Unpacking
All shipping boxes have been specially designed to protect their contents and
special care has been taken to prevent damage under normal shipping conditions.
Mishandling should be evident upon inspection of the shipping container. Carefully
remove your new component from its packing and examine it closely for signs of
shipping damage. We strongly recommend saving all original packing to protect your
component from damage should you wish to store it or ship it at a later date.
❷Installation
▷BE CERTAIN TO INSTALL THE UNIT IN A SECURE LOCATION FROM WHICH IT
CAN NOT FALL OR TIP OVER
▷
Provide adequate ventilation - the chassis will become warm in normal use. Do not
operateoncarpetoranyothersurfacethatmightblockairow
▷Do not allow the chassis to touch any metal parts, such as the frame of an
equipment rack. This might create a parallel ground path that could degrade the
sound of your system
▷
Connect the input and output cables. Input connection is via COAX , AES/EBU
TOSLINK or USB. Output can be via RCA or XLR jacks
IMPORTANT: READ THE SECTIONS “BACK PANEL”
WARNING: The unit should be operated only at rated voltage, indicated on the
power connector. If you are not sure what is the mains voltage supplied to your
home, consult with your unit dealer.
▷
Connect the power supply to the power source indicated on the rear panel.
Avoid power conditioners that float the ground pin. ALWAYS connect power
cord to component before plugging it into an AC outlet, and make sure that
unit main switch is set to the „off” position before making the final connection.
For best performance, try to route the power cord away from signal cables.
Pay close attention to power quality, and be aware that different power cords can alter
the sound.

Back Panel Functions
IEC Power Connector, Main Switch, Fuses and Input Voltage Selector
There are fuses located in the IEC power connector on the back panel. For 230
volts operation a 0.63 amperes “Slow Blow” fuse is used. For 115 volts operation
the fuse should be 1.25 amperes. If power does not come on, contact your
authorized service representative.

SUPERLINK is CEC’s proprietary digital signal transmission system that transports music
signals and synchronization(clock) signals with separate cables. The SPDIF(Sony Philips
Digital Inter Face) and AES/EBU(Audio Engineering Society/European Broadcasting Union)
systems, commonly used in coaxial digital outputs and optical outputs, transmit both the
music and clock signals through the same cable, and thus are prone to jitter effects caused
by the signals interfering with each other. CEC’s SUPERLINK system transmits these signals
separately with multiple cables, requiring no encoding/decoding process for data transmission.
It minimizes deterioration of the music signal during transmission by using the clock signals
from the D/A converter’s master clock generator to achieve complete synchronization. Each
transmission path delivers/receives the following signals.
MCK(Master Clock): The CD transport receives the master clock signal from the D/
A converter through this line, and functions as a slave to the DA converter, enabling
completely synchronized transportation of audio data.
BCK(Bit Clock): Sends bitclock signals, required for digital data bit identification(e.g.
sampling frequency) or signal readout, from the CD transport to the D/A converter.
LRCK(L/RClock):Sendsleft/rightidenticationclocksignalsfromtheCDtransporttothe
D/A converter.
DATA: Sends audio data from the CD transport to the DA converter.
