PRELIMINARIES
All of us at Wadia would like to offer thanks and congratulations to you
for purchasing the Wadia 861 Compact Disc Player. We sincerely believe
that your Wadia 861 will bring you many years of musical pleasure
and satisfaction.
While every new owner is anxious to begin listening, we encourage you to
take a few minutes to read this manual and familiarize yourself with the full
capabilities of the Wadia 861 Compact Disc Player.
If you are in a hurry to begin listening, please at least read the
sections of this manual where the symbol at left is shown.
Wadia was originally founded in 1988, making it one of the first high-
end audio companies dedicated to digital audio. Wadia was formed by
a group of telecommunications engineers from the Minneapolis-based 3M
Corporation who were committed to using advanced digital technology to
improve the performance of digital audio equipment.
Brief History
of Wadia
Wadia’s first product, the Wadia 2000 Decoding Computer, was a break-
through. For many listeners it proved the viability of Compact Disc as
a musically involving format. Since then Wadia has continued to develop
new methods and technology. Each product resulted in a new standard
of performance for digital audio decoding.
Here is an abbreviated list of the technological innovations Wadia
engineers have pioneered:
• Patented DigiMaster up-sampling algorithm, optimized for
reproducing music
• First company to apply glass fiber optics to home audio
• Direct-Connect™ system to connect digital audio products directly
to amplifier
• ClockLink™ proprietary jitter-reduction technology
• Swift-Current™ zero-feedback current to voltage converter
Although Wadia’s digital expertise and track record exceed those of any
audio company, technology alone does not guarantee musical performance.
Wadia designs are born of a delicate balance of technology shaped by a
passion for music.
Wadia is proud to introduce the Wadia 861 CD Player, a breakthrough
in sonic performance and value, and a strong statement of our years of ded-
ication to music.

INSTALLATION AND SET-UP
Unpacking
Use care in unpacking your Wadia 861 Compact Disc Player. Inspect it for
any shipping damage and call your dealer immediately if any is found.
Do not plug your Wadia 861 Compact Disc Player into an
AC outlet if you find shipping damage.
We advise saving all packing materials so that the unit can be easily and
safely shipped if the need arises.
Accessories
Provided with the Wadia 861 are the following accessories:
• AC power cord
• Four spiked feet with threaded studs
• Four steel coasters
• RCA/BNC adapter
• Transport Key (for locking/unlocking transport)
• Remote Control
• Three type AAA batteries
Do not tip the unit onto the back panel.
This can damage input and/or output connectors.
Unlocking the
Transport Mechanism
Place the Wadia 861 on its side on a surface that will not scratch the side
panel. Use the key found in the accessories kit to unlock the transport laser
assembly as shown on the label on the bottom of the unit.
(Note: the transport key need only be turned a small distance to either lock
or unlock the transport.)
In the event that the unit requires shipping, the transport must be
returned to the locked position.
Installing the
Spiked Feet
With the unit still positioned on its side, screw one of the spiked feet into the
bottom of each corner post.
Position the Wadia 861 where you would like it to reside in your system.
We recommend choosing a solid, non-resonant, level surface for best
performance. If this surface is susceptible to damage, place one of the steel
coasters under each spiked foot.
When positioning the Wadia 861, do not tilt the unit forward as it may
cause the laser assembly to become lodged in the disc clamping system.

CONNECTING THE
WADIA 861
TO YOUR SYSTEM
CHECK
VOLTAGE
HERE!
Check to make sure your Wadia 861 Compact Disc Player has been
manufactured for operation at your AC line voltage. Attempting to use
this Compact Disc Player at any voltage other than specified on the rear
of the unit may damage the unit. Damage caused by improper operation
is not covered by warranty. If the voltage specified is different from
your AC voltage, contact your Wadia dealer.
The best performance is obtained when the Wadia 861 is plugged
directly into the wall with the power cord provided. The Wadia 861 has
power conditioning, surge suppression and an extremely sophisticated
overall protection scheme. It should not be necessary to use surge protectors,
power conditioners or aftermarket power cords, some of which may degrade
sonic performance. If you wish to experiment with any of these devices, work
closely with your dealer – and most of all, trust your own ears.
Connecting the
Wadia 861
to AC Power
Connecting
Directly to a
Power Amplifier
Avoid allowing static shocks to be applied to the inputs or outputs.
To prevent static shocks, touch any grounded surface, such as the Wadia
861 chassis, before connecting or removing a cable. It is unlikely that a
static shock will damage the unit, but it may cause the Wadia 861 circuitry
to “lock-up” (see Lock-Up under Trouble Shooting).
Inputs and outputs can be safely connected to the Wadia 861
1. Before the unit is powered up
2. When the unit is in Relay-Mute mode
(See Mute Modes in General Operation)
We strongly recommend that you use your Wadia 861 connected directly
to your power amplifier. Even if you purchased your Wadia 861 with the
intention of connecting it to your preamplifier, we suggest that you try direct
connection to your amplifier. Many listeners are surprised by the improve-
ment in performance over even the most expensive preamplifiers.
To connect your Wadia 861 to a power amplifier, ensure that your power
amplifier is turned off, then connect your analog interconnects from the
Wadia 861 analog outputs to the amplifier’s inputs.
Using the
Wadia 861 with a
Preamplifier
While the Wadia 861 was designed to be used without a preamplifier, no
compromises were made in its design that will prevent excellent operation in
a conventional system with a preamplifier.
When using a preamplifier, set the Wadia 861 volume control to its
maximum level.
5
Wadia 861
COMPACT DISC PLAYER
Optimizing the
Output Level
Best performance is obtained when operating the Wadia Volume
Control near the top of its range. If needed, the maximum output level
of your Wadia 861 can be adjusted to match the overall sensitivity of your
system so that the critical listening will take place with the volume control
operating in near the top of its range.
The maximum output level of the Wadia 861 is adjustable by means of
a set of internal switches. The Wadia 861 is factory set to accommodate
the most common range of system sensitivity. If you find that your typical
volume level during critical listening is below 65 on the volume display,
it will be advantageous to use a different setting. To change the output level,
consult your dealer.
Your Wadia 861 is equipped with digital inputs which can accept digital
signals from any of the established digital formats.
Input 1: Glass-fiber optical
Connecting Other
Digital Sources
to your Wadia 861
Input 2: Coaxial with BNC connector
Input 3: Plastic-optical TOSLINK
Input 4: AES/EBU with XLR connector
The Wadia 861 digital inputs will decode any word length up to 24-bit, and
any of the standard digital audio sampling frequencies up to 96kHz.
While the Wadia 861 supports all currently accepted transmission formats
for digital audio, we recommend using a high quality glass-fiber cable such as
the one available from Wadia. Wadia Digital was the first company to
use glass fiber-optic data transmission in digital audio. We have continually
improved this format and believe that it offers the best, most consistent
performance of all the available options.
Choosing a
Digital Cable
Based on our experience, here is a list of digital interface methods in
descending order of performance:
1. Glass optical (as implemented by Wadia)
2. AES/EBU using XLR connector
3. Coaxial cable using BNC connector
4. Coaxial cable using RCA connector
5. TOSLINK plastic-optical cable
The quality of any of these transmission methods depends on the quality
of the cable and the sophistication of the transmitter and receiver.
For example, a high quality coaxial cable can outperform a low quality
AES/EBU cable. A high quality AES/EBU cable will outperform a poorly
implemented glass optical system.
If you are using a coaxial cable we recommend that you have the cable
terminated with a BNC connector. This will provide higher performance than
an RCA connector. Your Wadia 861 comes with an RCA/BNC adapter that
can be used for experimentation between different types of coaxial cable.
Again, we highly recommend that you take advantage of your dealer’s
experience and, most importantly, trust your ears.
All XLR-type inputs and outputs on the Wadia 861, both digital and analog,
use the standard audio pin configuration:
Pin 1 - Ground
Pin 2 - Positive signal
Pin 3 - Negative signal

FREQUENTLY ASKED QUESTIONS
Should I use a Balanced or Unbalanced connection?
If your amplifier has a true balanced input, we recommend you use the balanced analog output from
your Wadia 861 Compact Disc Player.
All things being equal, properly implemented balanced (also called differential) circuitry sounds better
than unbalanced circuitry. The Wadia 861 is a true balanced design. It generates the inverted signal in
the digital domain and all subsequent processing is done in balanced mode.
Your Wadia 861 is designed to maintain many of the advantages of true balanced design when using
the unbalanced outputs. In addition, the Wadia 861 output stage is capable of driving both types of out-
puts simultaneously.
Why should I bypass the Preamplifier?
A preamplifier is unnecessary when using your Wadia 861 Compact Disc Player. The Wadia 861
provides all the necessary control functions of a preamp while the signal is still in the digital domain.
This avoids the sonic degradation caused by analog circuitry, switches, and wire. The Wadia 861
output stage can drive any power amplifier and any interconnects, even very long lengths.
Does the Wadia Volume Control compromise resolution?
The Wadia 861 uses the latest generation of Wadia’s proprietary digital volume control.
The volume level can be varied in the digital domain by means of mathematical manipulation of
the signal, eliminating the distortion and noise that are inevitable with even the best analog volume
controls. While conventional thinking indicates that reducing the volume digitally can sacrifice low level
resolution, Wadia has created an innovative solution. Wadia’s patented digital filtering algorithm produces a
24 bit output rather than the 16 bits stored on the CD. This high-resolution signal is then used in the
computations which in turn reduce the volume level. This new signal is fed directly to the DAC chips.
Through this innovative method, the Wadia 861 maintains high resolution even at the lowest volume
control settings.
Can I bypass the Wadia Volume Control?
Because the Digital Volume control does not include any analog circuitry, there is none to be
bypassed. Even the mathematical program step that performs the Digital Volume Control calculation
is an integral part of the Wadia DigiMaster filter algorithm and therefore cannot be bypassed.
If you do not need the Wadia Volume Control, set it to its maximum level of 100 on the display.
What about Analog Sources?
In order to fully realize the potential of this type of system, Wadia has a range of Analog-to-Digital
converters. Now it is possible to use analog sources, such as a tuner, tape deck, or even a turntable
(in conjunction with a suitable phono stage) in your system without using a conventional analog
preamplifier. Consult your dealer for more information on the Wadia Analog-to-Digital products.
Should I leave the Wadia 861 with the power on?
The Wadia 861 is designed to be left with the power on with no harm or wear to the unit. All motors and
laser circuitry turn off when the unit stops playing. If desired, the front display can be turned off (see
Turning off the Display under Remote Operation). Leaving the power on allows the circuitry to remain
in thermally stable, which provides better performance and longer life. Careful listeners will notice that the
sound of the Wadia 861 will improve steadily after the unit is powered-up. A new unit will undergo more dra-
matic changes when power is applied for the first time. If you turn off your Wadia 861 for more than an
hour, you will find that the unit will undergo similar, but less dramatic improvement once power is reap-
plied.

Adjusting the Volume
Adjusting the Balance
Whenever the volume control buttons are pressed, the volume for both
channels will be increased or decreased by an increment of 1 on the display
screen. The range of the volume control is from 1 to 100, with each step
representing 0.5 dB change in volume.
Relative volume of each channel can be adjusted via the balance control but-
tons on the remote. Pressing one of the balance buttons increases the vol-
ume on that channel relative to the other by an increment of 0.2 on the dis-
play. This corresponds to a 0.1 dB change. The next time the button is
pressed the opposite channel is decreased. This way the overall volume
level (the sum of the two channels) remains constant within 0.1 dB.
Selecting an Input
The Wadia 861 has four digital inputs, plus the internal CD drive. Any of
the inputs can be selected from the remote control by pressing the input
button. Each time the input button is pressed, the next input is selected.
For example, if you are listening to CD input and you press the input select,
Input 1 will be selected, press it again, and Input 2 will be selected and
so on. After Input 4, the list will begin again with the CD input.
Whenever you select a new input, the display will switch to the Input Screen.

Inverting Absolute
The Wadia 861 has the ability to invert absolute phase in the digital domain.
Pressing the Phase Invert button on the remote control will cause the
Wadia 861 to invert phase; pressing it again will switch the phase back to
normal. If the Wadia 861 is in Phase Invert mode, this will be indicated on
the Input Screen of the display.
Phase
Turning Display
On/Off
By pressing the Display On or Off button, the Wadia 861 display can be
turned off completely.
If the display is turned off, it will reappear briefly whenever a Wadia 861 func-
tion button on the remote control is pressed.
Mute Modes
The Wadia 861 has two mute modes that are automatically implemented
under different circumstances.
DSP-Software Mute
When the Mute button is pressed on the remote control, the Wadia 861’s
DSP engine transmits a stream of zero signal level samples to the DAC
section, which results in zero output.
Output-Relay Mute
The Wadia 861 Compact Disc Player has mute relay connected between
the positive and negative outputs. When this relay is engaged, it connects
the positive output to the negative output, reducing the output to zero. This
relay, which produces an audible click when it engages or disengages, is
not in the music signal path. The mute relay is engaged:
1. When the Wadia 861 detects AC input level below its minimum
operating range.
2. Each time the Wadia 861 power switch is turned on.
3. When the volume control is set to zero AND the mute button on the
remote control is pressed.
When the Wadia 861 is in either Mute Mode, the Volume Screen will indicate
this by Displaying the word, “MUTE.”
INDEX/FORWARD/REV: Pressing these buttons allows access to the
previous or next index point within a track that has such indexed sections.
TRACK FORWARD/REV: Pressing these buttons allows access to the
previous or next track on a disc.
SEARCH/FORWARD/REV: Pressing these buttons allows fast reverse or
fast forward access through a track.
STOP: Pressing this button while a Compact Disc is playing stops PLAY.
PAUSE: Pressing this button, while a Compact Disc is playing, suspends
PLAY. Pressing the PLAY button or the PAUSE button will resume play at
the point where the pause button was pressed.
PLAY: After a Compact Disc has been loaded into the drawer, pressing
this button plays the disc beginning with the first track on the disc or in
a sequenced program. Pressing this button while the drawer is open,
closes the drawer and begins play with the first track on the disc or in
a sequenced program.

USING CLOCKLINK WITH AN EXTERNAL DIGITAL PROCESSOR
Theory of Operation
ClockLink eliminates jitter added when the clock signal is recovered from the
digital data stream. In a non-ClockLink system, jitter is added when the clock
signal is embedded in the data stream and transmitted to the DAC. When the
clock signal is recovered from the data stream (as shown below), and used to
clock the DAC output, this jitter degrades the sonic performance.
Data and Clock to DAC
Transport
DAC
Jitter added
Conventional CD Player
With ClockLink, the clock is not recovered from the data. Instead,
the master clock is located at the DAC. This clock signal is transmitted to the
transport to keep it synchronized with the DAC. Because the recovered clock
is ignored, any jitter on that signal does not affect the sonic performance.

CD Player with ClockLink
The Wadia 861 with its digital inputs and outputs can be used with a
digital signal processor such as a digital equalizer. Digital processors
allow the signal to be modified without adding analog noise and distortion.
However, digital processors can add jitter, as shown below, causing
noticeable sonic degradation.

Configuring Digital
Inputs for ClockLink
To utilize ClockLink with an external processor, the Wadia 861 digital inputs
must be configured for ClockLink as described below.
Use the Enter button to scroll through the display menus until you reach the
configuration menu for the input you wish to configure. Shown below
is the configuration menu for Input 1:
C o n f i g u r e
1 : C L O C K L I N K O F F
I N
Use the Volume Up or Volume Down button to change to ClockLink ON.
Press the Mute button to save the configuration.
Note: Using ClockLink with a source other than the internal
CD transport will result in unpredictable, degraded performance.
ClockLink should only be used when using an external processor which
is being fed by the 861 internal CD transport. For all other applications,
inputs should be configured with ClockLink OFF.
The Wadia 861 has several features to prevent ClockLink from being
engaged when it should not be. First, whenever the input signal is other
than 44.1 kHz sampling frequency, the Wadia 861 will automatically revert
to recovered clock mode. Second, if the internal transport is not running, the
Wadia 861 will revert to recovered clock mode.
Note: All inputs on the Wadia 861 are factory configured for
ClockLink OFF.
When the Wadia 861 is operating in ClockLink mode, the Input screen will
indicate this as shown below:
ClockLink Status

Even if an input is configured for ClockLink, the Status screen will only
indicate ClockLink if it is currently engaged. For example, if an input is
configured for ClockLink, and the Wadia 861’s internal CD transport is
turned off, then the display will not indicate ClockLink.

PROGRAMMING THE CD TRANSPORT
Program: Pressing this button enters all tracks subsequently chosen
with the numeric buttons (up to a total of 20 selections) as part of a
programmed sequence.
Programming a sequence of tracks can be done either in the stop mode or in
the play mode.
To program a sequence of tracks from a Compact Disc while in the stop
mode, first press the program button. The program indicator will illuminate in
the display window. Next, press the numeric buttons of the tracks you would
like to program in the sequence desired. The number of each selected track
will be indicated under the track indicator, the location of that track within the
program (the playing order) of the tracks selected will be indicated in the area
where index is usually identified, and the total program playback time
of the sequence will be updated as each track is programmed.
To program a sequence of tracks from a compact disc while in the play
mode, the procedure is the same. The only difference is that the total
program’s playback time will not be displayed.
A program will continue to be held in memory, even after that program has
been completely played.
When programmed playback is ended by pressing the stop button, the
program will continue to be held in memory. However, if the stop button
is pressed a second time, the programmed contents will be erased
from memory.
To exit the Program mode, press the program button again.
Single: To play a single track, press the single button (the single indicator
will light in the display window), then press the numeric button(s) which cor-
respond(s) to the track you would like to play. The transport will search for the
selected track, and playback will start from the beginning of that track. At the
conclusion of the track, the transport will stop.
To repeat a single track, press the single button (the single indicator will
illuminate in the display window), then press the repeat indicator (the repeat
button will illuminate in the display window), and then press the numeric
button(s) which correspond(s) to the track you would like to repeat. Playback
of the track selected will begin immediately.
Delete: This button is the opposite of normal programming. Pressing this
button while a program is being entered erases the entire entered program.
To play an entire disc, except for specific tracks that you do not want to hear,
press this button and then the numeric buttons corresponding the tracks you
would like to delete (up to 20 selections).
15
Wadia 861
COMPACT DISC PLAYER
Clear: When the program indicator is illuminated in the display window.
To eliminate a particular track from a programmed sequence, first press the
check button until the track which you would like to eliminate is selected.
Then press the clear button which will clear that particular track from memory.
Time: This button switches between the various time modes on the display.
Before play, the total time on the disc, or in a sequence program, is shown.
Once a disc starts to play the elapsed time of that track will be shown.
Pressing the button on the remote control once will cause the display to
indicate the remaining time in that track (remain). Pressing this button on
the remote control again will cause the display to indicate the remaining
time on the entire disc, or in a sequenced program (total remain).
Auto Space: Pressing this button will provide a four second space between
tracks on disk, irrespective of the actual time between tracks on disc.
Check: When a sequence of tracks has been programmed, the check button
can be used to review the contents of that program. After a program has been
entered, but before playback has begun, by pressing the check button once,
the first programmed track number, its position in the sequence of tracks that
have been programmed, and the playing time of the entire sequence, will be
displayed. Each subsequent pressing of the check button will provide similar
details as you move through each of the programmed tracks.
The programmed contents of a sequence can also be checked during play-
back, however, the total program’s playback time will not be displayed.
Repeat: Pressing this button will cause the entire dis to repeat continuously.
Pressing this button a second time will take the transport out of the repeat
mode. Pressing this button once, following pressing the single button, will
cause the track that is playing, or has been selected, to repeat continuously.
A/B: This button is used to define a section of a disc that is to be repeated
continuously. Pressing this button once defines the beginning point (A) of the
section to be repeated and pressing this button again defines the ending
point (B) of the section repeated.

DIGITAL
ALGORITHMS
In the Wadia 861 there are three user-selectable digital algorithms that can
be used to optimize the sonic performance based on system matching and
personal musical priorities.
The three algorithms in the 861 all upsample to 32x the CD input rate
(1.4112 MHz DAC sample rate), but differ in their time and frequency
domain characteristics. They are:
Algorithm A Digimaster v2.4. Wadia’s classic time-domain interpolation
algorithm delivers a robust sound with extraordinary image
focus and re-creation of recorded space.
Algorithm B Provides a more extended top end than Algorithm A,
with superior time-domain performance compared to
conventional CD filters.
Algorithm C Retains the high frequency extension and superior
detail resolution of Algorithm B, but with a more relaxed
presentation overall.
The selected algorithm is used for 44.1 kHz (CD) and 48 kHz sources,
either from the internal CD transport or any of the four digital inputs. For
88.2 kHz and 96 kHz sources, Digimaster v2.4 is always used as it provides
the best performance at high-sample rates.
We encourage you to become familiar with the unique sonic performance of
each of these algorithms and enjoy the one that brings you optimum musi-
cal pleasure.

STORED’ and the output of the 861 will mute for 5-10 seconds while the
selected algorithm is downloaded to the two DSP computers.
PERFORMING
ALGORITHM
COMPARISONS
When comparing processing algorithms it is important to adjust the volume to
compensate for the different gains of the algorithms. Without this adjustment
the one which is louder will usually sound better in a short-term A/B compari-
son.
In the 861, algorithm A has approximately 1 db higher output level than B and
C (which are within 0.1 db of each other). To compensate for this higher
level, increase the indicated volume setting by 2 units for algorithms B and C
when comparing them with A.

APPENDICES
Enabling/Disabling
the Digital Outputs
The Wadia 861 is designed in such a way that the unused digital outputs can
be disabled. This can result in slightly better overall performance. See your
dealer for information about these internal adjustments.
Troubleshooting
Lock-up
If the Wadia 861 experiences a powerful static shock or sudden AC surge,
it is possible to “lock-up” the computer circuitry. A locked-up computer may
result in erratic display, no output, and no response to remote commands.
If your Wadia 861 should lock-up, unplug the AC cord. Wait at least 30
seconds before re-plugging in the unit. If the unit still does not operate
normally, contact your dealer.
