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-
fier
1
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.

Note: The Wadia 321 is designed to be compatible with
the majority of Audio Power Amplifiers. However,
do to a wide range of Power Amplifier Designs it is
important the input sensitivity of the amplifier 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.
