PRELIMINARIES

All of us at Wadia would like to offer thanks and congratulations to you
for purchasing the Wadia 861 Compact Disc Player. We sincerely believe
that your Wadia 861 will bring you many years of musical pleasure
and satisfaction.

While every new owner is anxious to begin listening, we encourage you to
take a few minutes to read this manual and familiarize yourself with the full
capabilities of the Wadia 861 Compact Disc Player.

If you are in a hurry to begin listening, please at least read the
sections of this manual where the symbol at left is shown.

Wadia was originally founded in 1988, making it one of the first high-
end audio companies dedicated to digital audio. Wadia was formed by
a group of telecommunications engineers from the Minneapolis-based 3M
Corporation who were committed to using advanced digital technology to
improve the performance of digital audio equipment.

Wadia’s first product, the Wadia 2000 Decoding Computer, was a break-
through. For many listeners it proved the viability of Compact Disc as
a musically involving format. Since then Wadia has continued to develop
new methods and technology. Each product resulted in a new standard
of performance for digital audio decoding.

Here is an abbreviated list of the technological innovations Wadia
engineers have pioneered:

• Patented DigiMaster up-sampling algorithm, optimized for

reproducing music

• First company to apply glass fiber optics to home audio
• Direct-Connect™ system to connect digital audio products directly

to amplifier

• ClockLink™ proprietary jitter-reduction technology
• Swift-Current™ zero-feedback current to voltage converter

Although Wadia’s digital expertise and track record exceed those of any
audio company, technology alone does not guarantee musical performance.
Wadia designs are born of a delicate balance of technology shaped by a
passion for music. 

Wadia is proud to introduce the Wadia 861 CD Player, a breakthrough
in sonic performance and value, and a strong statement of our years of ded-
ication to music.
