"SUPERLINK" Digital Signal Transmission System

SUPERLINK is a 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.
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 identifi cation clock signals from the CD transport to the
D/A converter.
DATA: Sends audio data from the CD transport to the DA converter.
Remark: Whenever changing the D/A converter input to or from SUPERLINK the master
clock source is also switched to external or internal one. This master clock change will cause
the CD transport to re-read the disc information (TOC) resulting in cancelling every current
functional settings like programmed playback, repeat, dimmer and so on. Set those functions
again after re-reading out TOC.

Dimmer

Display brightness can be changed in different three levels. Press the DIMMER button
on the remote control unit to dim the display. The display brightness will toggle through
"brighter"(default), "off" and "lighter".
During "off" mode:
Opening the CD door "OPEn" and current
functional setting will be displayed in
"lighter" brightness temporarily. Closing
the CD door the display will be "off"
again automatically.
Pressing once the UPSAMPLE button the
current functional setting will be displayed
in "lighter" brightness temporarily
when upsampling and/or external word
clock has been activated. Press the UP-
SAMPLE button successively to change the sampling frequency. 5 seconds later the
display brightness will return to "off" automatically.
Remark: Pressing the UPSAMPLE button in Superlink mode the display brightness
won't change.
Regardless of any DIMMER setting the brightness will return to the default "brighter"
whenever turning the POWER on again or changing the D/A converter input to or from
SUPERLINK.
