5Rear Panel Names and Functions

ga Power Switch
Press the “-“ side to turn on the power and press the“o” side to turn off the power.
Note:• The power switch is intentionally not secured inorder to maintain the audio quality.

s AC Inlet (115 V AC)
Connect to a 115 V AC wall outlet (mains) with thesupplied power cable.
Notes:• Do not use any electrical contact cleaner or thelike in the AC inlet area.
• To maintain the audio quality, use the supplied power cable.
• Connect the power cable to the AC wall outlet (mains)by inserting the power plug prong with the engraved
OO symbols into the ground side (the longer hole).
If you reverse the orientation of the power plug, you
cannot fully enjoy the performance of the unit.
• Firmly insert the power cable into the end of the AC inlet.
• The ground terminal and the housing are not connected.
• The AC inlet is intentionally not secured in order tomaintain the audio quality.

d Power Indicator
When the power is on, the indicator is lit red.
Note:
• The indicator lights up blue when the clock is received
from the D/A converter.

f ZERO LINK Output Terminal(ZERO LINK OUTPUT)
A D/A converter such as our product S-3T or D-3T
can be connected to this terminal with a ZERO LINK
designated cable. This output terminal provides thehighest audio quality but special attention is required
for when connecting.

6fdsaNotes:• When connecting a ZERO LINK designated cable
to devices, turn off the power of the devices to beconnected together. Connecting/Disconnecting thecable while the power of the devices is on can cause
the devices to become faulty. Also, do not touch theconnector (where signals are transmitted) of theZERO LINK designated cable. Even when the powerof the devices is off, the devices might become faulty
due to static. Be sure to tighten the screws to secure
the cable.
• Connect the ZERO LINK cable to the ZERO LINK
terminal with a sticker of the same color as the plugof the ZERO LINK cable.

• Do not connect a computer monitor or the like to theterminal. It will cause a malfunction.

g USB Input Terminal (USB INPUT)
Connect to devices such as a music server, networktransport, and computer with a USB cable. For details,see CSR, Inc. website.
Note:• To connect to a Windows computer, a designateddriver is required. The driver can be downloaded
from CSR, Inc. website.

Protection Pads for Transport

Attaching the Spike Pins

Before use, be sure to remove the pads from the unit.
With the pads left attached, you cannot fully enjoy thehigh audio quality of the unit.

 y replacing the feet with the supplied spike pins,B
you can tune the audio quality. Point grounding makes
the sound focus and auditory lateralization sharper.
Furthermore, the audio quality can be subtly tuned
by changing the material of the surface on which thisequipment is installed.

• In order to maintain the audio quality, the top coverand terminals on the rear panel are intentionally notsecured.
• If you shake the unit, you will hear a rattling sound. Itis not an abnormality.
• When you transport the unit, reattach the pads to theoriginal places.

Notes:• When replacing the feet with the spike pins, remove thecarbon washers from the feet, and then reattach themto the spike pins.
• When the spike pins are attached, it may be difficult
to keep weight balance stable. Take great care not tocarelessly apply a force on the corners of the main unit.

Carbon washers

Cautions• When using the spike pins, be extremely careful
not to get injured, etc.
• When using the spike pins, be careful that thesurface on which the main unit is installed suchas the surface of a table, shelf, etc., may become
damaged.

Features of B-3
Feature 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: High-power Non-feedback Power Supply

A 200 VA toroidal transformer which has an enormous capacity and which is usually used for power amplifiers
is adopted. For the rectifier diode, ultra-fast SiC diode is adopted for the first time. A multitude of electrolytic
capacitors with low magnification and low capacity are connected in parallel to make up a group of rectifier
capacitors. For regulators, SOULNOTE unique non-feedback power is supplied.

Feature 3: Housing Designed with Highest Priority Placed on Audio Quality

The top cover with the top-bottom sides unsecured can prevent air-dumping. In addition, an unsecured AC
inlet, an unsecured output terminal, 3 spike supports located just under the transformer, titanium washers, andcarbon washers are adopted. These parts and ideas were adopted as a result of placing the highest priority
on audio quality.
