WARNING

DO NOT INGEST BATTERY, CHEMICAL BURN HAZARD

The remote control supplied with this product contains a coin/button cell battery. If the coin/button cell battery is swallowed, it can cause severe internal burns in just 2 hours and can lead to death. Keep new and used batteries away from children. If the battery compartment does not close securely, stop using the product and keep it away from children. If you think batteries might have been swallowed or placed inside of the body, seek immediate medical attention.

General Information

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 Microprocessor’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 reproduced as a positive pressure by the Loudspeaker. This would be referred to as “In Phase” reproduction 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

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.

Introduction

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 components. The 321 reproduction is sonically transparent and absolutely accurate. The Wadia Sound is “The Sound of the Music Itself.”

Performance Features

• Dual Function

Use the Wadia 321 as the Digital Preamplifer together with Digital Source Components and Power Ampli-

to form a complete Audio System. Connect the

fier 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 reliable, noiseless, distortion free switching.

• 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.

Introduction and Performance Features

• 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.

• 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 resolution.

Note: 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.

• Remote Control

The Remote Control provides control of the 321 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 Connectors Contacts are gold plated for superior corrosion resistance and high electrical conductivity.

Installation

The 321 is designed to be placed upright on a table or shelf, standing on its feet. The required ventilation requirements are shown. Always provide adequate ventilation for your 321. Cool operation ensures the longest possible operating life for any electronic instrument. Do not install the 321 directly above a heat generating device, such as a

Power Amplifier. Allow at least 2 inches (5.1cm) above the top, 5/8 inches (1.6cm) below the bottom and 1 inch (2.5cm) on each side of the 321, so that airflow is not obstructed. Allow 20 inches (50.8cm) of depth for

airf low and cable connections.
