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. ❷ Turning 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 first, before turning on the amplifier connected to the DA3N. Turning power off: Turn off the amplifier’s power first, before turning off the DA3N. ❸ Handle With Care Avoid exerting excessive force on the cabinet, the switch and the knob on the DA3N. ❹ Installation 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  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. ❺ Avoid lightning strikes Disconnect the AC power cord from the AC outlet when there is a thunderstorm in your vicinity. ❻ Condensation 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. ❼ Listening etiquette When adjusting the sound volume level, make sure you do not disturb other people and your neighborhood.  DA3N User's Manual Accessories DA3N should contain the following: ❶ DA3N unit ❷ BNC Cable x 4 ❸ AC Power Cord ❹ Remote Control unit ❺ Two AAA batteries for the remote control unit ❻ Owner's Manual NOTE: Keep the packaging available for future transportation needs.

The switch will light up in blue color when power is ON and "WAIT" is displayed. Approximately 6 seconds later the display will change to indicate the selected input, sampling frequency and options. ❷ OPT1 Input Connect to any digital audio device using an optical fiber cable with a mini round plug. This input supports sampling frequencies from 32kHz to 96kHz. ❸ USB1 Input Connect to a computer using a USB cable with a mini B plug. This input supports sampling frequencies from 32kHz to 96kHz but not 88.2kHz which is automatically upsampled to 96kHz. ❹ INPUT Selector Knob SL1 SL2 USB1 USB2 (Input changes per one click turn) COAX AES OPT3 OPT2 OPT1 Turn the INPUT knob clockwise or counterclockwise to select a digital input SL1(SUPERLINK / BNC), SL2(SUPERLINK / D-SUB), USB1(mini B type on front), USB2(B type), OPT1(optical mini round connector), OPT2(TOSLINK), OPT3(TOSLINK), AES(AES/EBU) or COAX(COAXIAL). The selected input is displayed at Ⓐ and the display shows the sampling frequency at Ⓑ once Ⓐ Ⓑ DA3N detects the digital input signal. Note: Whenever changing the input "Unlock" is displayed in a flash before  DA3N User's Manual the sampling frequency is displayed. Note: Due to the input signal quality DA3N sometimes can not lock the signal properly resulting in having a noise in the music. In that case select the input again to reset the locking. Note: Whenever changing the input to or from the SUPERLINK the master clock source is also switched to external or internal to cause the CD Transport to stop the playback. Push the CD play button again to resume the playback. When changing the input, set the volume to lower level to avoid speaker damage! Each input signal varies the sound level and it might amplify the small noise to the big one. ❺ DISPLAY ⒶThe selected digital input is displayed. Ⓐ Ⓑ Ⓓ Ⓒ ⒷThe selected input sampling frequency is displayed. When no or incompatible signal is there "Unlock" or "Unknown"(at USB) is displayed. When the volume knob is turned the level is displayed for 6 seconds. Ⓓ Ⓐ Ⓑ Ⓒ ⒸThe selected digital filter type is displayed. "P" is displayed when "PULSE" is selected or "F" for "FLAT". You may change the digital filter by remote control. Refer to page 10 about the digital filter function. ⒹAn external master clock input is displayed. "M" is displayed when a SUPERLINK is selected and an external master clock 44.1kHz is connected. The same external master clock is supplied to the CD Transport via DA3N. ❻ REMOTE Sensor The remote sensor, which receives signals from the remote control unit, is located at the right side of display. Address the remote control unit to the sensor correctly. The remote control unit may malfunction if there should be any obstacles between the remote control unit and the remote sensor. ❼ VOLUME Knob The volume at headphone output and Variable output level can be  D/A CONVERTER DA3N adjusted. Turn counterclockwise to minimize the volume to see VOL 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. -90dB -80dB -72dB (6 dB changes by step) -54dB (3dB changes by step) VOL MUTE (Minimum Volume) (Maximum Volume) 0dB (1dB changes by step) -42dB Note: VOLUME woks both headphone and Variable outputs. Unused one should be switched off or disconnected. ❽ HEADPHONE Jack Headphone output jack for standard 6.3 mm plug. Note: For using a headphone with 3.5mm mini plug, purchase a 6.3mm conversion plug from a dealer. Before using your headphones for listening, turn the volume to the minimum and insert the headphones plug into the jack. Excessive sound pressure from the headphones may cause hearing loss to your ears. Digital Filter 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. 10 DA3N User's Manual 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 identification clock signals from the CD transport to the D/A converter. DATA: Sends audio data from the CD transport to the DA converter. 11 D/A CONVERTER DA3N Rear Panel Functions ❶ ❸ ❺ ❷ ❹ ❻ ❼ ❿ ❽ ❾ ● VARIABLE Analog outputs You may adjust the analog output level of DA3N by turning the VOLUME knob.
