All of us at Wadia would like to offer thanks and congratulations to you  
for purchasing the Wadia 301 Compact Disc Player. We sincerely  
believe that your Wadia 301 CD is an intelligent purchase decision that  
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 301 CD.  
To reduce the risk of injury or damage to your Wadia 301 CD, please  
read the safety instructions on the first page of this manual. In addition,  
please pay particular attention to the sections of this manual where the  
symbol at left is shown.  
A Brief History of Wadia  
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.  
Wadia’s first product, the Wadia 2000 Decoding Computer, was a  
breakthrough in that it proved the viability of Compact Disc as a  
musically involving format. Wadia has continued to develop new  
methods and technology and each successive product has resulted in  
a new standard of performance for digital audio decoding. Here is an  
abbreviated list of the technological innovations Wadia engineers  
pioneered:  
Patented DigiMaster™ up-sampling algorithm, optimized for  
extracting maximum musical information from digital-audio data  
stream.  
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.  
4
Wadia’s digital expertise and record of accomplishment exceed those  
of any audio company, but 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 301 CD Player, a breakthrough  
in sonic performance and value, and a strong evidence of our  
dedication to music reproduction.  
Wadia 301 CD Design Philosophy  
The Wadia 301 Compact Disc player is the first of Wadia’s new 3 –  
series, a range of products that set a new standard for performance,  
aesthetics, and value. The Wadia 301 CD has received the benefit of  
over 12 years and thousands of hours of development that have  
resulted in the Wadia legacy. Viewed this way, the Wadia 301 CD is  
one of the most outstanding values in the world of high-end music  
reproduction.  
Wadia Digital Volume Control with Direct-Connect™  
The Digital Volume Control and Direct-Connect circuitry perform the  
functions of a preamplifier while the signal is in the digital domain. This  
allows the Wadia 301 CD to be connected directly to your power  
amplifier, bypassing the losses inherent in conventional preamplifiers.  
New in the Wadia 301 CD is the ability to optimize the output level to  
match your system by setting switches on the Wadia 301 CD rear  
panel.  
5
Swift Current I-V Converter  
The Wadia 301 CD is the first Compact Disc player in this price range to  
use Wadia’s patented Swift Current technology. This proprietary,  
custom-fabricated integrated circuit performs the sonically critical  
current-to-voltage conversion with no negative feedback, resulting in  
demonstrably superior sound quality.  
The Music Comes First  
As with all Wadia products, the Wadia 301 CD is the result of a design  
philosophy that bridges the gap between the traditional engineering  
and empirical approach to audio design. That is, Wadia engineers are  
guided equally by advanced measurement techniques and extensive  
listening during the development process. The result is performance  
that exceeds the expectations of even the most demanding listener.

Installation ____________________  
This section includes information on how to unpack and position your  
Wadia 301 CD.  
Unpacking  
After carefully unpacking your Wadia 301 CD, inspect for any shipping  
damage and call your dealer immediately if any is found. Do not plug  
your Wadia 301 CD into any outlet if you find shipping damage.  
Please save all packing materials so the unit can be easily and safely  
shipped if the need arises.  
The Accessory Kit  
Included in the carton, you will find an accessory kit that contains the  
following:  
AC power cord  
Remote Control  
Two type-AAA batteries  
Three cone feet and flat metal discs  
One BNC-to-RCA adapter  
Installing Batteries In Remote Control  
The Wadia 301 CD remote control requires two batteries, which you will  
find in the accessory kit. To install the batteries, unscrew the battery  
cover on the back of the remote. Insert the batteries as indicated on  
the battery holders, and replace the cover.  
7
Installing Cone Feet  
The Wadia 301 CD is equipped with three cone feet that screw into  
inserts in the bottom panel. These feet will improve performance by  
reducing vibration. If the Wadia 301 CD is sitting on a shelf that can be  
damaged by the sharp feet, place the steel discs under each foot to  
protect the shelf surface.  
Choosing a Location for the Wadia 301 CD  
The sound quality of all high-performance digital and analog  
components can be degraded by vibration. Although the Wadia 301  
CD uses some of the most advanced noise-reduction circuitry  
available, it too will benefit from any efforts taken to reduce vibration.  
For best performance, place the Wadia 301 CD on a solid, non-  
resonant shelf that will minimize vibration.

Avoid allowing static shocks to be applied to the inputs or outputs. To  
prevent static shocks, touch any grounded surface, such as the chassis  
of a component that is plugged into an AC socket, before connecting  
or removing a cable. It is unlikely that a static shock will damage the  
unit, but it may cause the Wadia 301 CD circuitry to lock-up (see  
Trouble Shooting in Appendices).  
Inputs and outputs can be safely connected to the Wadia 301 CD:  
When the AC power is switched off OR  
When the unit is in Relay-Mute mode (See Mute in Operation)  
Connecting to AC Power  
Check to make sure your Wadia 301 CD has been manufactured for  
operation at your AC line voltage. Attempting to use your Wadia 301  
CD at any voltage other than specified on the rear of the unit may  
cause damage that is not covered by Wadia’s warranty.  
9
Using AC Line Conditioners  
Of the wide range of power line conditioners currently available, some  
can provide substantial improvement in sound while others actually  
degrade sonic performance. Use caution in selecting a power line  
conditioner for your system. In particular, avoid using inexpensive “surge  
protectors”. Although these can prevent damage from high voltage  
spikes, they often degrade performance.  
Leaving the AC power on  
The Wadia 301 CD is designed to be able to have the AC power on  
with no harm or wear to the unit. To reduce wear and power  
consumption, all motors and laser circuitry turn off when the unit stops  
playing. Leaving the power on allows the circuitry to remain at a  
constant operating temperature, providing better performance and  
longer life. However, there is always a slight increase in risk of fire or  
damage to any electrical component when the power is left on. We  
leave the decision to leave the Wadia 301 CD powered to the  
individual owner.  
Break-in and warm-up  
Careful listeners will notice that the sound of the Wadia 301 CD  
improves steadily after the unit is powered-up. A new unit will undergo  
more dramatic changes when power is applied for the first time.  
Depending on the resolution of the system and the attentiveness of the  
listener, you may find that the sound continues to improve over the first  
several weeks of operation. If the power is disconnected for a period of  
an hour or more, the unit will undergo similar but less dramatic break-in.  
Questions about Connecting the Wadia 301 CD  
To help you decide the best way to connect the Wadia 301 CD to your  
system, read the following list of question asked by Wadia owners:  
10  
Direct-Connect™ or Pre-Amplifier?  
The Wadia 301 CD is designed to produce excellent performance in  
systems with or without preamplifiers. However, in many systems a  
preamplifier is unnecessary when using your Wadia 301 CD. The Direct  
Connect technology incorporated into the Wadia 301 CD provides all  
the necessary control functions of a preamplifier while the signal is still  
in the digital domain. This avoids the sonic degradation caused by  
analog circuitry, switches, and wire. The Direct-Connect output stage  
can drive any power amplifier and any interconnects, even very long  
lengths. Many listeners are surprised by the improvement in  
performance compared to even the most expensive preamplifiers.  
Even if you purchased your Wadia 301 CD with the intention of  
connecting it through a preamplifier, we suggest that you experiment  
with direct connection to your amplifier.  
Does Direct-Connect™ compromise performance with a preamplifier?  
Although we encourage listeners to bypass their preamplifier, the  
Wadia 301 CD is not compromised in any way when used with a  
preamplifier. The Wadia 301 CD performs all preamplifier functions  
such as input selection and volume control in the digital domain. As a  
result, there is no circuitry associated with Direct-Connect that affects  
the audio performance. The Wadia 301 CD offers uncompromised  
performance in systems with and without preamplifiers.  
How should I connect Analog Sources?  
To use analog sources in a system using Wadia’s Direct Connect  
system, Wadia has introduced the Wadia 130 and 150 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.  
11  
Bypassing the Wadia Digital Volume Control  
Strictly speaking, the Wadia Digital Volume Control cannot be  
bypassed, because it is not in the analog signal path to begin with.  
Unlike conventional volume controls, there is absolutely no circuitry in  
the analog signal path of the Wadia Digital Volume Control -- no  
passive parts, switch contacts, resistors, or even circuit board traces.  
The Wadia Digital Volume Control operates in the digital domain; it  
comprises one computer-programming step in the Wadia’s digital filter  
algorithm. Even this program step cannot be bypassed, because it  
performs the important function of preventing the digital signal from  
exceeding the maximum level that can be processed by the digital to  
analog converter chips.  
If you are connecting the Wadia 301 CD to a preamplifier or amplifier  
with a volume control, you can set the Wadia 301 CD volume control  
to the maximum level (99).  
Connecting Directly to an Amplifier  
To connect your Wadia 301 CD to a power amplifier, ensure that your  
power amplifier is turned off, and then connect your analog  
interconnects from the Wadia 301 CD balanced or unbalanced  
analog outputs to the amplifier’s inputs.  
Connecting to a Preamplifier  
To connect the Wadia 301 CD, simply connect the balanced or  
unbalanced analog outputs from the Wadia 301 CD to a pair of line-  
level inputs on the preamplifier.  
When using a preamplifier, turn the Wadia 301 CD volume control to its  
maximum volume (99).  
12  
Adjusting the Maximum Output Voltage  
The Maximum Output Voltage is the output voltage when the volume  
control is set to maximum setting (99). The Maximum Output Voltage is  
factory set to 4.0 V on the balanced output and 2.0 V on the  
unbalanced output. You can adjust the Maximum Output Voltage on  
the Wadia 301 CD to match your system by setting the two small  
switches on the rear panel as shown in the table below.  
13  
Infrared Input and Pass-through  
The Wadia 301 CD is equipped with a pair of 1/8" mini-plug infrared (IR)  
pass-through jacks. The IR pass-through jacks can be used with an IR  
receiver/transmitter system to send remote control commands directly  
to the Wadia 301 CD. This may be useful for example, if the Wadia 301  
CD is located outside the field of view of your listening position.  
Optional Digital Inputs  
Digital inputs are available as an option on the Wadia 301 CD. The  
digital inputs allow you to connect other digital sources and receive the  
benefits of Wadia’s decoding performance. The Wadia 301 CD Digital  
Input card has the following inputs:  
Input 1: Glass-fiber optical  
Input 2: Coaxial with BNC connector  
Input 3: Coaxial with BNC connector  
Input 4: Plastic-optical TOSLINK  
All inputs automatically adjust to any of the standard digital-audio  
data-rates from 32 to 96 kHz.  
Digital Output  
The Wadia 301 CD is equipped with one digital output to allow the  
internal CD transport to feed another component, such as a digital  
recording device. The digital output is a S/PDIF signal on a high-quality  
BNC jack.  
14  
Choosing a Digital Cable  
For maximum performance we recommend using an ST glass-optical  
cable, which can be purchased from your Wadia dealer, for any  
digital audio connections. Wadia Digital was the first company to use  
glass fiber-optic data-transmission in digital audio and we believe that  
it offers the best performance of all the available options. Based on our  
experience, here is a list of digital interface methods in descending  
order of performance:  
1. ST-type Glass optical (as implemented by Wadia, with high  
quality glass-optical cable)  
2. AES/EBU using XLR connector  
3. Coaxial S/PDIF cable using BNC connector  
4. Coaxial S/PDIF 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 S/PDIF cable can  
outperform a low-quality AES/EBU cable. A high-quality AES/EBU cable  
may outperform a poorly implemented glass-optical system  
If you are using a coaxial S/PDIF connection, we recommend having  
the cable terminated with a BNC connector. This will provide higher  
performance than an RCA connector. Your Wadia 301 CD input kit  
comes with an RCA/BNC adapter that can be used for experimentation  
between different types of coaxial S/PDIF cables.  
Again, we highly recommend that you take advantage of your dealer’s  
experience and, most importantly, trust your ears.  
Connecting to the Digital Inputs or Output  
To connect to either the digital inputs or output of the Wadia 301 CD,  
simply connect the appropriate digital input or output to the outboard  
component.

OPEN/CLOSE  
Pressing the OPEN/CLOSE key causes the disc-loading drawer to either  
open or close. You can also close the drawer by gently pushing on the  
drawer front, or by pressing PLAY or SKIP FORWARD.  
PLAY  
Pressing PLAY causes the unit to begin playing. If the drawer is open,  
pressing PLAY will close the drawer before playing begins.  
STOP  
Pressing STOP causes the disc to stop playing.  
PAUSE  
Pressing PAUSE suspends playing until play is pressed, or until pause is  
pressed again. Playing will resume at the same point on the CD where  
the pause button was pressed.  
18  
SKIP FORWARD/SKIP BACK  
Pressing these keys skips to the next or previous track. SKIP FORWARD  
always moves to the next track. However, the function of the SKIP BACK  
key is different. If a CD is playing, pressing SKIP BACK once will return to  
the beginning of the current track. Pressing SKIP BACK repeatedly will  
select the previous tracks. If the CD is not playing, then pressing SKIP  
BACK will move to the previous track.  
VOLUME UP/DOWN  
Pressing these keys increases or decreases volume by 0.5 dB for each  
time the key is pressed. The two-digit LED on the front panel indicates  
the volume level, with a range of 0-99. When the volume is set to zero  
the output is muted. Volume level of 01 is –50dB from maximum  
output, and each successive step increases the output by ½ dB until  
maximum output is reached and the display indicates 99.  
MUTE  
The Wadia 301 CD has two mute modes that are automatically  
implemented under different circumstances.  
1. Software Mute: When the MUTE key is pressed on the remote  
control, the Wadia 301 CD DSP engine transmits a stream of zero  
signal-level samples to the DAC section, which results in zero  
output.  
2. Relay Mute: The Wadia 301 CD 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 under any of the following three  
conditions:  
Each time the Wadia 301 CD power switch is turned on.  
When the Wadia 301 CD detects AC input level below its  
minimum operating range.  
When the volume control is set to zero AND the MUTE key on  
the remote control is pressed.  
When the Wadia 301 CD is in either software or relay mute, the Mute  
indicator on the front panel will illuminate. Note that the CD will  
continue playing even when the output is muted.  
19  
INPUT  
The Wadia 301 CD can be configured with four optional digital inputs  
(See section on Optional Inputs). Each time the INPUT key is pressed,  
the next input is selected. For example, if you are listening to the  
internal CD drive, and you press the INPUT, 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 internal CD drive.  
INVERT  
Pressing the INVERT key on the remote control will cause the Wadia 301  
CD to invert phase; pressing it again will switch the phase back to  
normal. When the phase is inverted, the INVERT indicator on the front  
panel will illuminate.  
REPEAT  
Pressing this button once will cause the current track to repeat  
continuously. Pressing the REPEAT key a second time will repeat the  
entire disc or program continuously. Pressing it a third time will stop  
repeating. The repeat mode is indicated by the front panel display.  
PROGRAM  
The PROGRAM key can be used to create a program to play tracks on  
a disc in any order you choose. Follow these steps to create a  
program:  
1. While the unit is stopped, use the SKIP keys to select the first  
track in the program.  
2. Press the PROGRAM key to enter that track into the program  
3. Repeat until all desired tracks are entered.  
4. Press PLAY to hear the tracks in the program order  
5. Opening the disc loading drawer or turning the power off will  
erase the program.  
Direct Access Keypad  
Use the direct access keypad to move directly to any track on the disc.  
For track numbers greater than 10, use the >10 key to set the first digit  
and then one of the number keys for the second digit.  
20  
Appendices _____________________  
Trouble Shooting  
If the Wadia 301 CD 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 301 CD should lock-up, unplug the AC cord. Wait at least  
30 seconds before plugging the unit in again. If the unit still does not  
operate normally, contact your dealer.
