Frequently Asked Questions

Should I use a Balanced or Unbalanced connection?

If your amplifier has a true balanced input, we recommend you use the balanced

analog output from your Wadia 121Decoding Computer. All things being equal,

properly implemented balanced (also called differential) circuitry sounds better

than unbalanced circuitry. The Wadia 121Decoding Computer is a true balanced

design. It generates the inverted signal in the digital domain and all subsequent

processing is done in balanced mode. Your Wadia 121Decoding Computer is

designed to maintain many of the advantages of true balanced design when

using the unbalanced outputs. In addition, the Wadia 121Decoding Computer

output stage is capable of driving both types of outputs simultaneously.

Why should I bypass the Preamplifier?

A preamplifier is unnecessary when using your Wadia 121Decoding Computer.

The Wadia 121Decoding Computer provides all the necessary control functions

of a preamp while the signal is still in the digital domain. This avoids the

sonic degradation caused by analog circuitry, switches, and wire. The Wadia

121Decoding Computer output stage can drive any power amplifier and any

interconnects, even at very long lengths.

Does plugging in headphones turn off the speakers?

Yes, the speakers will be muted and the balance (L/R) centered. When the

headphone jack is removed, the speaker volume and balance settings will return

to the previous setting.

Here is a brief list of the technological innovations the Wadia engineers

have pioneered over the past 20 years:

• DigiMaster

™

patented algorithm (filter optimized for reproducing music)

• ClockLink

™

proprietary jitter reduction technology

• SwiftCurrent

™

current to voltage conversion technology

• First outboard Digital-to-Analog converter

• First to apply glass fiber-optics to home audio

• First to recognize jitter as a source of audible distortion

• First to perfect digital volume control

• First high-end CD player competitive with expensive separates

• First company to provide bit perfect digital audio output from the iPod

While Wadia’s digital expertise and track record exceed those of any audio

company, technology alone does not guarantee an immersive and captivating

musical performance. Wadia’s designs are born of a delicate balance of technology

shaped by a passion for music.
