Handling Precautions

❶Connecting Other Devices

Unplug the DA3N’s AC power cord from the outlet before connecting or

disconnecting other devices. Exercise caution when handling the AC

power cord. When disconnecting the AC cord from a socket, make sure

you pull the plug, and not the cord itself.

❷Turning Power On/Off

Your system components should be turned on/off in the following order to

avoid generating noise from your speakers and damaging the speakers

themselves or other devices:

Turning power on: Turn on the DA3N’s power rst, before turning on the

amplier connected to the DA3N.

Turning power off: Turn off the amplier’s power rst, before turning off the

DA3N.

❸Handle With Care

Avoid exerting excessive force on the cabinet, the switch and the knob on

the DA3N.

❹Installation

Use of an audio rack is recommended to maximize the sound quality

and performance of the DA3N. Installation and use of the DA3N in the

locations described below may cause deterioration in sound quality or

malfunction:

● Locations exposed to direct sunlight, such as windowsills, and

AC POWER CORD CONNECTION

CAUTION:

TO PREVENT ELECTRIC SHOCK, MATCH THE BLADE WIDTH

OF THE PLUG TO THE SLOT WIDTH. THE PLUG MUST BE

FULLY INSERTED TO THE SLOT.

For CANADA

D/A CONVERTER DA3N

other exceptionally warm locations, such as near heating appliances

(surrounding temperature higher than 35 °C), or exceptionally cold

locations (surrounding temperature lower than 10 °C), may prevent the

DA3N from functioning adequately.

● Damp locations exceeding 90% humidity may cause the DA3N’s

metal parts to rust, causing the unit to malfunction.

● Dusty locations may cause the DA3N to malfunction. The

accumulation of dust inside the CD door may lower the performance of

music signal reading. It may also cause contact failure of the switches,

and/or noise.

● Otherwise, avoid installing the DA3N close to other transformers and

electrical motors, so as to prevent the pickup of induction hum. Also,

avoid mounting the unit on surfaces that may be affected by vibration.

❺Avoid lightning strikes

Disconnect the AC power cord from the AC outlet when there is a

thunderstorm in your vicinity.

❻Condensation

When the DA3N is brought into a warm room when the exterior

temperature is cold, or when the room temperature rises sharply from

using a heater, condensation may form both inside and outside the unit,

hampering its performance. If this happens, leave the DA3N unused in

the room for 1 to 2 hours (depending on the amount of condensation),

so as to bring the unit’s temperature closer to the room temperature. The

condensation should go away gradually.

❼Listening etiquette

D/A CONVERTER DA3N

Push the DF button on the remote control to select a digital filter FLAT or

PULSE.

●The FLAT digital Filter is very common in digital audio items. The

frequency response is almost perfect, but such filter cause "ringing" in the

time domain. Some energy of a pulse signal is distributed in the time domain,

before and after the pulse centre. Any ringing before the signal does not exist

in nature.

●The PULSE filter avoids the problems in the time domain and thus has

a very good response in the time domain. The frequency response of the

PULSE digital filter shows a soft roll-off at high frequencies. This results in

about -2dB at 20kHz with an input sampling frequency of 44.1kHz. For higher

sampling frequencies the roll-off is irrelevant and the "PULSE" filter is the

best choice. For 44.1kHz and 48kHz the better result may depend on the

whole system as well as personal preferences.

Digital Filter

MUTE. Turn clockwise to see -90dB, -80dB, -72dB by each step. After

-72dB one step goes by 6dB up to -54dB, and up to -42dB by 3dB. After

-42dB volume will be increased by 1dB at one step.

Note: VOLUME woks both headphone and Variable outputs. Unused

one should be switched off or disconnected.

❽HEADPHONE Jack

FLAT PULSE

"SUPERLINK" Digital Signal Transmission System

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.
