Ultra Low-Jitter D/A Converter

DA1N
Supports various digital inputs including USB and CEC’s proprietary SUPERLINK.
Fully conveys music information from high quality digital sound sources.

Using high quality BNC cables to ensure minimal signal interference, the DA1N makes it
possible to transmit high quality signals from its ideal counterpart - the TL1N belt–drive CDtransport - to the DAC, free of distortions and jitter. The DA1N also offers five different digital
inputs (including USB for input from a PC), supporting a wide variety of musical needs.

Evolved SUPERLINK Connection and Multiple Digital Inputs

CEC’s proprietary SUPERLINK system minimizes sound deterioration
due to signal interference by transmitting four kinds of digital signals
separately ; music, master clock, bit clock and L/R clock signals.
Accounting for the possibility of potential deterioration caused by thecables themselves, the DA1N offers a new connection using four separate
high quality 75Ω BNC cables in addition to conventional 9-Pin D-subconnection. Especially when coupled with CEC’s “TL1N” CD transport,
the DA1N accurately conveys the genuine atmosphere of the originalmusic source.
Five digital inputs are supported ; SUPERLINK, AES/EBU, COAXIAL,TOSLINK, and USB, the latter enabling input from personal computers.

Thorough Elimination of Jitter

The quality of the input music signals is a major factor in digital music
reproduction. As the signals transmitted through the SUPERLINK system
are synchronized with the servomechanism-synchronizing clock, whichis generated from the DA1N’s master clock, they are unaffected by jitter- digital noises caused by time lags in the signals, which tend to affectsound dynamics and listener immersion. Packet signals from a PC thatenter through the USB input are also synchronized with the DA1N’s
master clock during USB/I2S conversion, and are thus unaffected by jitter.
When it comes to SPDIF inputs such as AES/EBU, COAXIAL, TOSLINK,
however, measures to reduce jitter are necessary since these signals
often include jitter. The DA1N offers effective jitter elimination with thejitter-resistant high-precision PLL circuit featured in its SPDIF receiver,and by placing a sample rate converter (SRC) just before the signal
reaches the DAC circuit. The input signals are resampled to 96kHz by theSRC, which operates synchronously with the DA1N’s master clock. Thesignals are thus completely isolated from the jitters included in the initial

clock signal. Furthermore, for high-quality low-jitter SPDIF music signals
the DA1N offers the option of bypassing the SRC circuit.

Three Different Oversampling Frequencies

The DA1N features two independent DACs (Burr Brown PCM1792A×2) for right and left in a dual-mono configuration, and a choice of
three oversampling frequency settings; 128fs for the strongest, 64fs forintermediate, and 32fs for the softest filtering effect and impact on soundquality. The DA1N uses the Delta-Sigma method, which offers a strong
quantizing noise filtering effect, for post-oversampling demodulation.

Two Types of Digital Filter

The DA1N offers two different digital filters; “FLAT”, a standard filter withsuper linear frequency response to 20kHz, and “PULSE”, a ringing-freepulse-optimized filter with a softer roll-off below 20kHz.

Feedback-free and Fully Balanced Analog Circuitry

The DA1N’s analog section features a newest-version Current Injection(CI) circuit, which omits the feedback loop and its potential drawbacks onsound quality, as well as fully balanced circuitry, which results in a truly
balanced XLR output in addition to an unbalanced RCA output. The RCA
terminals feature high-quality custom-made parts.

Miscellaneous Features•The DA1N features a high-grade switching power supply with an active ACpower -cleaning circuit, as well as three separate transformers that independentlysupply power to the digital audio section, analogue section and control section.
•The power supply is protected by an internal shield housing to eliminate
electronic interferences to the audio section.
•A large VFD monitor indicates the input status, the input sampling rate and theoversampling rate.
