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
