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.
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

Unpacking Use care in unpacking your Wadia 151PowerDAC mini. Inspect it for any shipping damage and call your dealer immediately if any is found. Do not plug your Wadia 151PowerDAC mini into an AC outlet if you find shipping damage. We advise saving all packing materials so that the unit can be easily and safely shipped if the need arises.
Installing Battery in Remote Control The Wadia 151PowerDAC mini remote control requires two AAA batteries, which you will find in the accessories kit. To install the batteries, remove the battery cover on the back of the remote. Insert the batteries as indicated on the battery holders, and replace the cover. ◆Connecting to AC Power Check to make sure that the power cord shipped with your Wadia 151PowerDAC mini has been manufactured for operation at your AC line voltage.
◆Using AC Line Conditioners The Wadia 151PowerDAC mini employs extensive power-line filtering and noise suppression technology so fine performance is available with the Wadia 151PowerDAC mini plugged directly into a wall outlet using the AC power cord provided. However many users report gains in sound quality when using power conditioners or after-market power cords. If you wish to experiment with any of these devices we recommend working with your dealer and trusting your own ears for what sounds best.
Connections Avoid static discharge to the inputs or outputs. To prevent static shocks, touch any grounded surface, such as the chassis of any component that uses a grounded 3-prong plug, before connecting or removing a cable.
◆Speaker Outputs The speaker outputs are on the back of the Wadia 151PowerDAC mini. Connect the left speaker to the left speaker terminals and the right speaker to the right speaker terminals. Make sure you keep the Wadia 151PowerDAC mini positive terminal (red) with the positive terminal on the speaker and the negative (black) on the Wadia 151PowerDAC mini with the negative (black) on the speaker. ◆Connecting the Digital Inputs The Wadia 151PowerDAC mini has 4 digital inputs on the back.
