Features of This ProductFeature 1: ZERO LINKZERO LINK is a standard formulated by SFORZATO and SOULNOTE. It is an ultimate link for achieving as
high audio quality as possible. ZERO LINK dramatically reduces workload of the D/A converter and eliminates
asynchronous circuity from the housing of the D/A converter. This product handles entire asynchronous circuitand ZERO LINK transmits only signals that are polished by the sophisticated clock transmitted from the D/Aconverter, to the D/A converter. As a result, unparalleled audio quality can be obtained. ZERO LINK is asolution that surpasses even the highest-level analog playback.
Note:• A ZERO LINK designated cable is supplied with this product.

Feature 2: Ultra Powerful Non-feedback Discrete Power Supply

For this product, we employed the high regulation transformer for digital audio transmission from our productD-3T as is. With an extraordinary huge capacity transformer of 260 VA, we built 4-system non-feedback
discrete power circuits where each circuit is independent from windings. A total of 16 ultra-high speed SiC
rectifier diodes and a total of 70 low-magnification electrolytic capacitors are used. As a result, we could obtaingreat power of expression along with high audio clarity and wide audio dispersion .

Feature 3: SFP Port

Inserting a module for optical connections allows you to establish a connection with an optical cable. Also,
inserting a RJ45 module allows you to use a general LAN cable.
Note:• A module for optical connections, an RJ45 module, an optical cable, and a LAN cable are not supplied withthis product.

Feature 4: SC-cut Ultra-low Phase Noise OCXO

We daringly employed SC-cut OCXO for the SFP-circuit designated clock. It is an asynchronous circuit but westill increased the quality of the clock to the maximum for obtaining higher audio quality. For the I2S generation
circuit during the ZERO LINK connection, the high-quality master clock of the D/A converter transmitted via
ZERO LINK is used, and the system is fully synchronized with the master clock.

Feature 5: Thoroughly Unsecured Housing

The AC inlet, output and input terminals, circuit board, circuit board chassis as well as the top panel are
all unsecured. Also, every ounce of SOULNOTE expertise was utilized for the titanium washers and spikes
immediately provided beneath the transformer. Furthermore, air volume generated due to the relatively large
housing dramatically broadens the sound field.

AnalogoutputZERO LINK not only transmits master clock or I2S signals but also performs communications. In other words,
the transport informs the audio source format to the D/A converter before playback, and the DDS of the D/Aconverter generates a high-quality master clock that synchronizes with this audio format and then transmits itto the transport. The transport generates a pure I2S signal that synchronizes with the master clock and thentransmits it to the D/A converter. As a result, the system from the DAC to transport can be fully synchronizedwith the DAC master clock, completely eliminating the need for asynchronous circuits which decrease theaudio quality.
● Internal operation of ZERO LINK connections
During the ZERO LINK operation, asynchronous circuit operations can be completely eliminatedfrom the D/A converter.
