Should I leave the Wadia 121Decoding Computer with the power on?
The Wadia 121Decoding Computer is designed to be left with the power on with no harm or wear to the unit. While the power light is always illuminated, the volume and input sections of the front display can be minimized by pushing the display command on the remote control. Leaving the power on allows the circuitry to remain thermally stable, which provides better performance and longer life. Careful listeners will notice that the sound of the Wadia 121Decoding Computer will improve steadily after the unit is powered-up. A new unit will undergo more dramatic changes when power is applied for the first time. If you turn off your Wadia 121Decoding Computer for more than an hour, you will find that the unit will undergo a similar, but less dramatic improvement once power is reapplied.

Troubleshooting:
Lock-up
If the Wadia 121Decoding Computer 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 121Decoding Computer should lock-up, unplug the AC cord. Wait at least 30 seconds before re-plugging in the unit. If the unit still does not operate normally, contact your dealer.

Does the Wadia Volume Control compromise resolution?
The Wadia 121Decoding Computer uses the latest generation of Wadia’s proprietary digital volume control. The volume level can be varied in the digital domain by means of mathematical manipulation of the signal, eliminating the distortion and noise that are inevitable with even the best analog volume controls. While conventional thinking indicates that reducing the volume digitally can sacrifice low level resolution, Wadia has created an innovative solution. Wadia’s patented digital filtering algorithm produces a 32-bit output. This high-resolution signal is then used in the computations that in turn reduce the volume level. This new signal is fed directly to the DAC chips. Through this innovative method, the Wadia 121Decoding Computer maintains high resolution even at the lowest volume control settings.
Can I bypass the Wadia Volume Control?
Because the Digital Volume control does not include any analog circuitry, there is none to be bypassed. Even the mathematical program step that performs the Digital Volume Control calculation is an integral part of the Wadia DigiMaster filter algorithm and therefore cannot be bypassed. If you do not need the Wadia Volume Control, set it to its maximum level on the LED display.
Wadia Digital – a Brief History
Wadia Digital, founded in 1988, is one of the original companies dedicated to high performance digital audio reproduction. Wadia was formed by a team of engineers from the Minneapolis based 3M Corporation (Minnesota Mining and Manufacturing) who shared many years of experience in advanced digital
telecommunications research and development. In the early 1980’s,these engineers became intrigued by the emerging compact disc technology. Disappointed with the sound quality of early CD players, they examined the workings and designs of these early components and found them to be unsophisticated when compared with the technology available in other areas of digital design. In response, they founded Wadia Digital – a company based on the philosophy of applying advanced technology to improve the performance of digital audio components. Wadia’s first product, the Wadia 2000 Decoding Computer, was an absolute breakthrough in digital audio. For many discerning listeners, it proved that Digital Audio was a musically responsive, evolving, and engaging format.
Building on a tradition of excellence, Wadia continues to develop innovative technology; refining, listening, engineering, and improving along the way. Since the Wadia 2000, new generations of industry-leading designs were introduced and embraced by listeners around the world. Each step of the way, Wadia consistently raised the standard for performance of Digital Audio playback.
