channel.
6. When discarding the unit, comply with
local rules or regulations. Batteries should
never be thrown away or incinerated but
disposed of in accordance with the local
regulations concerning battery disposal.
7. For additional information on the di322 and other
Wadia Products please visit the Wadia Web Site at
www.wadia.com.
1. For additional connection information, refer to the
owner’s manual(s) for any component(s) connected
to the di322 digtial audio decoder.
2. The Main AC Power going to the di322 and any
other Wadia Component(s) should not be applied
until all the system components are connected
together. Failure to do so could result in mal-
functioning of some or all of the system’s normal
operations. When the di322 and other Wadia Com-
ponents are in their Standby Power Off Mode, the
Microprocessor’s Circuitry inside each component
is active.
3. The Unbalanced Outputs and Balanced Outputs can
be used simultaneously.
4. The di322’s internal Digital to Analog Converter
Circuitry is designed to decode 2-channel PCM
(Pulse Code Modulation) Digital Signal present at
the Coaxial, Optical and USB Digital Inputs. Other
Digital Audio Signal Format Types will cause the
Audio Outputs of the di322 to be muted.
5. The term “Absolute Phase” relative to reproduction
of sound by Loudspeakers (or headphones) refers
to the phase of the reproduced signal relative to the
original signal, retaining the original polarity. This
applies regardless of the number of audio channels.
A positive pressure on the microphone is repro-
duced as a positive pressure by the Loudspeaker.
This would be referred to as “In Phase” reproduc-
tion and is normal. When positive pressure on the
microphone is reproduced as a negative pressure by
the Loudspeaker, this would be referred to as “Out
of Phase” reproduction and is not normal. The vast
majority of recordings are made with all channels
in “Absolute Phase”.
The term “Absolute Phase” is not the same as
“Phase Reversal” where there is a polarity reversal

Introduction
Performance Features
Introduction and Performance Features
The Wadia di322 digtial audio decoder is one of the
finest Digital to Analog Processors ever created with
connections for digital sources including USB. The
di322 Outputs have the ability to drive multiple com-
ponents. The di322 reproduction is sonically transpar-
ent and absolutely accurate. The Wadia Sound is “The
Sound of the Music Itself.”
• Dual Function
Use the Wadia di322 as the Digital Preamplifer
together with Digital Source Components and Power
Amplifier1 to form a complete Audio System. Connect
the Wadia di322 to an exisiting Analog Audio System
to provide the latest in Digital-to-Analog Conversion
from digital audio sources.
• Electronic Input Switching
Electronic Input Switching on all Inputs provides reli-
able, noiseless, distortion free switching.
• Digital Audio Inputs
The di322 has Coaxial, Optical, DIN and USB Digital
Inputs to Decode PCM and DSD Signals from an ex-
ternal source. The Coaxial and Optical Inputs process
Digital Signals up to 192kHz with 24-Bit resolution.
The Digital DIN connection allows for streaming of
high bandwidth digital signals (DSD, PCM) directly
into the di322 from external sources. The USB Input
processes Digital Signals up to 192kHz with 32Bit
resolution, decodes DSD128 Digital Signals and DXD
24Bit with a sampling rate of 352.8 (or 384).
• Quad Balanced Digital to Analog Converter
The 8 channel 32-bit, 192kHz Digital to Analog
Converter is used in a Stereo Quad Balanced Mode,
assuring the music is reproduced with a wide dynamic
range and extremely low distortion, for both Disc and
external sources.
• Balanced Outputs
The Balanced Outputs allow the connection of long
cable lengths without a loss in sound quality.
• High Performance Headphone Output
The separate Headphone Power Amplifier Circuitry
is designed to produce high power output into Head-
phones with a low output impedance.
• Precision Tracking Volume Control
Volume levels are controlled by a Digitally Controlled
Attenuator System with a tracking accuracy of 0.5dB.
• Alphanumeric Fluorescent Display
The Front Panel Information Display indicates the
Source Selection, Sampling Frequency, Volume Level,
Output Phase and Setup Mode Selections. The display
intensity is adjustable.
• Trigger Input and Output
A Trigger Control connection for convenient Turn-On
of Wadia Power Amplifiers, Source Components and
Accessories is included.
1Note: The Wadia di322 is designed to be compatible with the majority of Audio Power Ampliers. However, do to a
wide range of Power Amplier Designs, it is important the input sensitivity of the amplier be at least 2 Volts.
This will assure the playback of most music recordings is reproduced with adequate dynamic range.
• Remote Control
The Remote Control provides control of the di322
operating functions.
• Special Power Supply
Fully regulated Power Supplies and a special R-Core
Power Transformer ensure stable noise free operation
even though the power line varies.
• Gold Plated Connectors
The Input and Output Connector Contacts are gold
plated for superior corrosion resistance and high elec-
trical conductivity.
• LED Front Panel Indicators
Long life Light Emitting Diodes (LEDs) are used to
indicate when the Setup Mode is active and when the
di322 is in the Standby Mode.
• Die Cast Aluminium Chassis
Maintains cool operating temperatures of the internal
circuitry by the heat dissipating properties of the die
cast aluminium chassis. The aluminium chassis with
illuminated top glass panel is very durable and will
retain its appearance for many years to come. This en-
sures the durability and functional design of the di322
will be retained for many years.

Control Panel Settings
To activate the Wadia-HD USB Audio Control Panel
Click on the “Wadia Icon” (located in the Windows
notification area on the right side of the taskbar) or
click on the Windows “Show hidden icons”, then se-
lect the “Wadia Icon”. Refer to figures 84 and 85.

default settings.
2. The Wadia-HD USB Audio Control Panel dis-
plays the current Sampling Rate, Bit-Rate and
Buffer Size for the music streaming from the
computer into the di322.
3. When the Media Stream Program on the com-
puter is set to output in the “ASIO” format the
Wadia -HD USB Audio Control Panel allows
for changing the setting parameters on the fly.
USB Music Playback
When the USB Input is selected on the Wadia di322,
the Front Panel Display indicates the Sampling
Rate (refer to figures 86 and 87 for PCM Signals).
Figure 80
Figure 81
Figure 82
Figure 83
Figure 85
Figure 84

19
Figures 88 and 89 indicate a Sampling Rate of 64 or
128 times the Sampling Rate of a CD Disc for the
incoming DSD Digital Audio Signal.
The Sampling Rate and the Bit Rate is determined by
the original recording, the Application Output Format
(when available) and the Wadia-HD Control Panel
Settings.
Note: In general, when the original music is recorded
at a higher Sampling Rate, the result is usually
more detail in the music. However, this higher
rate results in consuming larger amounts of stor-
age space. The Sample Rate usually should be set
to match the Sample Rate of the music recording
being played back.
There are many third party Applications (besides Ap-
plications like Windows Media Player) for steaming
music from the computer to Wadia di322 USB Input.
An example of just one of the available applications is
“JRiver Media Center”.
