General Information

1. For additional connection information, refer to the owner's manual(s) for any component(s) connected to the 321 decoding 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.

1. 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.

Performance Features

- Dual Function

Use the Wadia 321 as the Digital Preamplifier together with Digital Source Components and Power Amplifier ^1 to form a complete Audio System. Connect the Wadia 321 to an existing 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.

• 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 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.

• 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 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.

• 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 durability 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.

LATENCY:

The default Latency Setting is chosen for contemporary 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 selected 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 storage 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”.
