Wadia Digital, founded in 1988, is one of the

original companies dedicated to high performance

digital audio reproduction. Wadia is based on the

philosophy of applying advanced technology to

improve the performance of digital audio compo-

nents.

Wadia has consistently raised the standard for

performance of Digital Audio playback. Some of

the technological innovations pioneered by Wadia

include:

• DigiMaster™ patented algorithm (lter opti-

mized for reproducing music)

• ClockLink™ proprietary jitter reduction tech-

nology

• SwiftCurrent™ current to voltage conversion

technology

• First outboard Digital-to-Analog converter

• First to apply glass ber-optics to home audio

Our designs are born of a delicate balance of

technology shaped by a passion for music. Wadia

continues to re-dene the limits of digital music

playback.

and negative terminal connections on any given

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 321 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 321decoding computer.

2. The Main AC Power going to the 321 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 malfunctioning

of some or all of the system’s normal operations.

When the 321 and other Wadia Components are in

their Standby Power Off Mode, the Microproces-

sor’s Circuitry inside each component is active.

3. The Unbalanced Outputs and Balanced Outputs can

be used simultaneously.

4. The 321’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 321 to be muted.

5. The term “Absolute Phase” relative to reproduction

of sound by Loudspeakers (or headphone) 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

between the Amplifier and Loudspeaker positive

Performance Features

Introduction and Performance Features

The Wadia 321 Decoding Computer is one of the

finest Digital to Analog Processors ever created with

connections for digital sources including USB. The

321 Outputs have the ability to drive multiple compo-

nents. The 321 reproduction is sonically transparent

and absolutely accurate. The Wadia Sound is “The

Sound of the Music Itself.”

• Dual Function

Use the Wadia 321 as the Digital Preamplifer together

with Digital Source Components and Power Ampli-

fier1 to form a complete Audio System. Connect the

Wadia 321 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 321 has Coaxial, Optical and USB Digital Inputs

to Decode PCM Signals from an external source. The

Coaxial and Optical Inputs process Digital Signals

up to 192kHz with 24Bit resolution. The USB Input

process Digital Signals up to 192kHz with 32Bit reso-

lution.

• 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.

• Precision Tracking Volume Control

Volume levels are controlled by a Digitally Controlled

Attenuator System.

• 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.

• Remote Control

The Remote Control provides control of the 321 oper-

ating 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 Connectors Contacts are gold

plated for superior corrosion resistance and high elec-

trical conductivity.

1Note: The Wadia 321 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 are reproduced with adequate

dynamic range.

• LED Front Panel Indicators

Long life Light Emitting Diodes (LEDs) are used to

indicate when the Setup Mode is active and when the

321 is in the Standby Mode.

• Die Cast Aluminium Chasiss

The ensures the durablility and functional design of

the 321 will be retained for many years.

Wadia USB Audio Driver Operation

Control Panel Settings

The 321 USB Control Panel allows changes to be

made from the default settings. These include Latency,

Sample Rate and Audio Stream Input Output (ASIO)

Control. Refer to figure 18.

Note: It is not necessary for the Wadia USB Control

Panel to be running, unless it is desired to make

changes to the default settings.

L AT E N C Y:

The default Latency Setting is chosen for contempo-

rary computers and their performance capabilities.

When the Wadia USB Audio Driver is installed on

a legacy computer with slower processing speed, it

may occasionally produce clicks/pops in the music. To

resolve this if it occurs, increase the Latency Setting

(increase buffer size).

SAMPLE RATE:

The Sample Rate pull down Window indicates the

Sample Rate choices of the connected Wadia USB

Digital Audio Product. It also communicates the se-

lected choice of Sampling Rate to the active Windows

Playback Program.

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.

ASIO HOSTS CAN CHANGE:

There are two choices. When the box is not checked

(default setting), the Sample Rate is determined by the

Sample Rate Setting in the Wadia USB Control Panel.

It would be an appropriate choice when using a play-

back program like Windows Media Player.

If a third party program for music playback is

ASIO compliant then check the box. These programs

allow changing the Sample Rate Setting directly “on

the fly” according to the format of the music being

played back. An example of just one of the available

programs is “JRiver Media Center”.
