Features

The world’s first* mono D/A converter that
realizes the full potential of the Super
Audio CD format

(* as of August, 2004)

Our approach of “improvement in sound quality through
discrete L/R channel transmissions” has evolved into a
completely discrete L/R system having two D-01s, one
handling the left channel, and the other the right channel.

The left and right audio signal paths have nothing at all for
common use, both paths are completely isolated and
identical, creating the highest possible reproduction quality,
non-compromised sound. This system also proves its ability in
reproducing ambience and presence data and recreates
details of the performance environment or a feeling of the
original recording session.

What’s more, because each channel has its own power
supply, the design of this supply can be optimized with ample
headroom, achieving an ideal D/A conversion.

• 2 XLR (ES-LINK), 1 RCA, and 2 IEEE 1394 inputs are provided

• DSD signals from Super Audio CD are fed in through XLR
terminals in an Esoteric-exclusive format, ES-LINK, or through
the IEEE 1394 interface.

• A maximum 192 kHz PCM signal can accepted (both Dual
and Stereo transfers available).

• When stereo or multi-channel signals are fed in, only the
sound of the channel you set as explained in the section,
“Channel Selection”(pages 11 and 13), is selected.

• Three digital filter options are provided: FIR, RDOT, and
FIR+RDOT. The filtered signal is converted up to a maximum
768 kHz and then sent to the multi-bit D-A converter
PCM1704. The DSD signal from Super Audio CD is converted
to 88.2 kHz or 176.4 kHz PCM data before being sent to the
digital filter.

• Equipped with RAM-Link (Refined Asynchronous Memory
Link), using a high-precision crystal oscillator, that when
entering word sync mode, the RAM-Link is automatically
activated and acts to eliminate jitter caused before the first
stage of the DAC.

• For the D/A converter, a combination of as many as eight
PCM1704 multi-bit D-A converters is used for the best
possible S-N ratio and linearity, which makes it possible to
faithfully replicate the ambience and presence of the
performance environment.

• The driver circuitry that sends out D/A converted signals uses
a discrete circuit structure operating on ±42 volt rails with
emphasis on driving force and slew rate, making a significant
contribution to the remarkable sound.

Word Sync enabled - Making Synchronizing
with External Equipment Possible

The word sync feature operates either in “OUT” mode (as a
word clock generator) or in the “IN” mode that allows this
unit to lock to an external word clock. It can lock to 44.1,

88.2, 176.4, 48, 96, 192, 100, 48P, 96P, 192P and 100P
(kHz) inputs/outputs. (“P” represents “4% down mode for
PAL films”.)

Selecting the “Rb IN” mode will select a PLL circuit devoted
solely to synchronizing with a rubidium or other high­precision clock. The use of ESOTERIC’s rubidium master clock
generator G-0s, will produce the most remarkable listening
experience with a feeling of speed and subtle clarity.

Analog potentiometer allows a direct
connection to a power amplifier

With the built-in analog potentiometer (“VOLUME”),
concern’s over truncating or dropping bits, as used in digital
attenuators, is negated.

Copper wires of 6N purity are used for
primary internal wirings, further enhancing
sound quality

High purity 6N copper wires are used for the supplied AC
power cord and most of the internal wirings that may have
effect on the sound quality, thereby boosting the purity and
resolution for a crisp, textured sound.
For the insulating sheath, polyorefin, non-PVC material, is
used out of environmental considerations as well as sound
quality. PVC is not used for any wiring inside the unit. The
high purity 6N copper cable is developed with the help of
Acro Japan Ltd. as is the case with the Esoteric “MEXCEL”
interconnection cable and high purity 8N copper cable.

Highly rigid chassis is immune to internal
and external vibrations that might degrade
sound quality

Thick aluminum is used on the top, side, bottom panels and
rounded corners in addition to the front panel. The entire
body is supported by Esoteric-exclusive pinpoint feet (patent
pending) made of case-hardened tool steel. Exacting
attention is given to the highly precise mounting of all
mechanical parts, the rigidity of the housing, and the
elimination of sympathetic vibrations. To make double sure,
an 8-mm thick plate is used for the upper cover that is subject
to the sound pressure and vibrations from the speakers.

The front and side panels, constructed of thick brushed
aluminum, and the rounded four corners create a feeling of
dignity and gravitas, fitting only to the top level mono D/A
converter for Super Audio CD/CD.

i.LINK (IEEE 1394)

The i.LINK format, also known as IEEE 1394, is an international
specification for the transferring of extremely fast data.
This unit is ready for i.LINK (AUDIO).
By connecting an i.LINK (AUDIO)-capable device to the IEEE 1394
(or i.LINK AUDIO) terminal on this unit using an i.LINK cable, you
can transmit Super Audio CD multi-channel signals that could
not be transmitted except in analog format in the past. With
i.LINK AUDIO, Super Audio CD can be transmitted in its original
digital format, in addition to the capability of transmitting 2-ch
linear PCM data and multi-channel compressed audio signals.

If you have multiple i.LINK-capable devices, you can connect
them through other devices to transmit data between them.
With i.LINK, you don’t need to be concerned about the order of
connection and wiring errors and phase issues are virtually
eliminated.

Copyright protection system DTCP

To play back audio sounds recorded on Super Audio CD or DVD
discs using i.LINK, both the player and the D/A converter need to
be ready for the copyright protection system DTCP (Digital
Transmission Content Protection). The D-01 already accepts
DTCP.

Data transfer rate

There are three transfer rates: 100 Mbps (S100), 200 Mbps
(S200), and 400 Mbps (S400). This unit is capable of transferring
data at a maximum 400Mbps.

For connection to an i.LINK-capable device, use a commercially
available S400-compliant 6-pin i.LINK cable.

When connecting multiple i.LINK-capable devices, avoid
connecting a device having slow transfer rate between devices
having high transfer rate since this reduces the transfer rate of
your whole system. Connect devices having high transfer rate
towards the source as far upstream as possible.

NOTES

<

Among the i.LINK formats there are “MPEG-2 TS” for BS
digital source and “DV” for digital video for DVD recorders,
as well as the “i.LINK (AUDIO)” (A&M Protocol). Never
connect devices that are not ready for i.LINK (AUDIO) to this
unit. If you do, this unit and others may get out of order or be
damaged.

<

In the process of data transfer, avoid plugging or unplugging
the i.LINK cables while in use or switch the power on and off.

< Among the i.LINK-capable devices there are some that, if not

turned on, are not capable of relaying data.

< There is a possibility some i.LINK-capable devices will not

respond to this unit’s command.

How to connect multiple i.LINK-capable
devices

Daisy chain connection

You can daisy-chain up to 17 devices including this unit.

Connection in tree structure

If you are using a device having three or more i.LINK connectors,
you may want to get the connection branched out. This way of
connection allows you to connect up to 17 devices including this
unit.

Your system does not work if data is fed back to the output
device. Be careful not to create a loop.

CBA D FE

Display

The equipment draws nominal non-operating power from
the AC outlet with its POWER switch in the OFF position.

WORD

Use this button to switch between word sync modes. A mode
indicator lights up to show the current mode (blue indicators
showing normal modes, and a purple indicator showing the
4% down mode). The indicator blinks when no usable word
sync signal is detected. No indicator lights when word sync is
not being used.

OUT

Lets the unit internally generate and send out Word Clock
so the unit acts as a master.

IN

This mode provides a stable sync operation with most
general external clocks. There are occasions when sync is
not achieved depending on the output accuracy of the
devices in use. This is because the word clock input
frequency range of this unit is set to as narrow as ±15ppm,
a requirement in order to achieve a sync of high accuracy.

Rb IN

This is a mode designed for external clocks of a higher
degree of precision like a rubidium clock generator. Select
this mode when this unit is connected to the ESOTERIC G-0s.
Keep in mind that it will take time before the sync is
achieved in this mode. This mode requires an even narrow
bandwidth of accuracy to lock.
Switch the mode to IN when “WRD UNLOCK” or “WRD
ERROR!” is shown.

Off (tuned off)

The unit does not use any word sync.

B

4% down mode

Pressing and holding this button for more than 3 seconds
switches the unit back and forth between 4% down and
normal modes.

<

Selecting IN or Rb IN modes achieves sync by using an
external clock as master. When in those modes, the word
clock fed into the WORD SYNC IN terminal is directly sent out
through the WORD SYNC OUT terminal.

<

This unit readily accepts a maximum 196 kHz clock and
automatically switches itself to the incoming signal.

< When selecting IN or Rb IN modes, the corresponding

indicator blinks and searches for an external clock. When the
unit detects a clock and locks to it, the indicator lights steadily
(blue) to show that the unit is ready for play.

<

Make connections to the WORD SYNC terminals prior to
powering on the unit.

(factory setting) are available.

<

With the DSD set to 176.4 kHz and the DSD gain to +6, there
is a chance that the sound will be distorted when playing
back discs on which music is recorded at very high volume
levels. If this is the case, set “the DSD to

88.2 kHz and the

DSD gain to +6” or “the DSD to 176.4 kHz and the DSD gain
to

0”.

<

When the DSD gain is set to 0, Super Audio CD discs are
played back at a lower level than CDs are.

Low-pass analog filter (80kLPF)

The use of this filter produces a subtle difference in sound
directivity. Switch this filter on or off (default) depending on
your preference.

With this filter switched off, there is a chance that unexpected
and abnormal noise could be produced and harm your
speakers or trip the protection circuit on your power amplifier.
To protect your system it is recommended that this filter be
switched ON.

IEEE 1394 remote control function (1394RC)

When multiple D-01 units are directly connected using IEEE
1394 cables and you have this function on, the functions of
all D-01’s in the chain can be controlled using only the left
channel D-01. The P-01 source should be the first machine in
the IEEE 1394 chain followed by all the D-01’s. (Do not
connect the P-01 between the D-01 units.)

The linking of the control functions among the D-01s is
available as long as IEEE 1394 cables are used to connect the
D-01 units. You can use a different input type other than
IEEE 1394 if you chose. If you do use a different input type,
by also connecting the D-01s with IEEE 1394 cables you can
control all D-01s with only one unit as long as this function is
switched on.

With this remote control function switched off, the IEEE 1394
circuit is powered only when the input is set to IEEE 1394.

Dimmer

The display and indicators can be dimmed to suit the
environment in which you listen to music. There are three
levels and an “off” setting.

<

In OFF mode, when you press any button, the illuminations
turn temporarily on.

< Note that the OFF setting is not memorized when the power

is turned off. When the unit is switched off with the display
off, and then turned on again, the display is reset to the
minimum brightness (Dimmer1).

<

The factory setting is “Dimmer3”.

Troubleshooting

If you experience any problems with this unit, please take the
time to look through this chart. You may be able to solve the
problem yourself before calling your dealer or technical support.

No power

e

Check the connection to the AC power source. Check and
make sure the AC source is not a switched outlet and that,
if it is, the switch is turned on. Make sure there is power to
the AC outlet by plugging in another item such as a lamp or
fan.

No sound from speakers.

e

Check the connection to the digital device, amplifier and
speakers.

e

If the volume bypass is off, adjust the output level using the
OUTPUT buttons.

The INPUT indicator blinks.

e

Turn on the digital device connected to the input terminal.

e

Check the connection to the digital device. Make sure the
source digital device and the input selection on the D-01 are
the same type.

The safety circuit of the power amplifier is activated.
High-frequency noise from speakers.

e

Set 80kLPF to ON.

Buzzing noise produced at regular intervals.

e

The connected unit may not be in word sync mode while
the D-01 is in word sync mode. Check the word sync
terminal for correct connection and the settings on the
connected unit.
Normally, if this problem occurs, the display reads “WRD
ERROR”, but this message does not appear when deviation
in sync is too small and out of the word error detection
threshold of the D-01.

The WORD indicator blinks.
The display shows “No Word!”

e

The word sync mode is selected, but there is no clock
source. Turn the word sync mode off (see page 9).

e

Invalid word clock is being received. Check cables,
connections, and settings of the clock generator.

The display shows “WRD ERROR!”

e

Invalid word sync signal is received. Check the setting of the
clock generator.

The display shows “WRD UNLCK!”

e

Cannot lock the word sync signal. If “Rb IN” is selected,
select “IN” using the WORD button.

If normal operation cannot be recovered, unplug the
power cord from the outlet and plug it in again. This
resets the internal micro-computer which can be disturbed
during electrical storms, power interruptions, et cetera.

ES-LINK

appears when the ES-LINK compatible Esoteric product is
connected.

No Word!

There is no clock source.

UNKNOWN

The unit connected via the IEEE1394 cable is unknown.

WRD ERROR!

Invalid word sync signal is received.

WRD UNLCK!

Cannot lock the word sync signal.

LOOP ERR!

IEEE1394 connection is looped.

< Normally, “the sampling frequency of an incoming digital

signal” when a CD is played back or “DSD” when an Super
Audio CD is played back are shown on the left of the display.
At the right shows the output level.

<

No output level shows when VOLUME BYPASS is switched on.

<

When detecting a device that is connected with IEEE 1394
cable, the display shows its model name (such as P-01).
