TroubleShooting:
Lock-up
If the Wadia 581 Disc Player experiences a powerful static shock or sudden AC surge, it is possible to
“lock-up” the computer circuitry. A locked-up computer may result in erratic display, no output, and no response
to remote commands.
If your Wadia 581 Disc Player should lock-up, unplug the AC cord. Wait at least 30 seconds before replugging in
the unit. If the unit still does not operate normally, contact your dealer.

Brief History
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 engineers 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 breakthrough. For many listeners it proved
the viability of the 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:
• First company to introduce an outboard Digital-to-Analog converter
• First company to develop an audio optimized upsampling digital filter
• First company to apply glass fiber-optics to home audio
• First company to recognize clock-jitter as a source of audible distortion
• First company to test and apply mechanical de-tuning to the development of audio
component chassis design
• First company to offer a CD perfect digital volume control
• First company to develop a Direct to Digital Amplifier - PowerDAC
• Patented DigiMaster upsampling algorithm, optimized for reproducing music
• RocLock proprietary jitter reduction technology
• ClockLink proprietary jitter reduction technology
• Swift-Current zero-feedback current to voltage converter
• Direct-Connect system to connect digital audio products directly to an amplifier
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 581 Disc Player, a breakthrough in sonic performance and value, and a
strong statement of our years of dedication to music.
