W a DIGITAL Wadii Digital Corporation was founded in 1988, making it one of the oldest digital audio companies in existence. Wadia was formed by a group of engineers from the Minneapolisbased 3M Corporation (Minnesota Mining and Manufacturing) who had compiled many years of experience in advanced digital and telecommunications research and development. In the early 1980’s, this group had become intrigued by the emerging CD technology.
After carefully unpacking your Wadia 27i Decoding Computer, inspect it for any shipping damage and call your dealer immediately if any is found. V Do not plug your Wadia 27i Decoding Computer into any outlet if you find shipping damage. Please save all packing materials so the unit can be easily and safely shipped if the need orises.
Q CHECK VOLTAGE HERE1 v Check to make sure your Wadia 27i Decoding Computer has been manufactured for operation at your AC line voltage. Attempting to use your Wadia 27i Decoding Computer at any voltage other than specified on the rear of the unit may cause damage which is not covered by Wadia's warranty.
v Avoid albwing static shocks to be applied to the inputs or outputs. To prevent static shocks, touch any grounded surface, such as the Wadia 27i chassis, before connecting or removing a cable. It is unlikely that a static shock will damage the unit, but it may cause the Wadia 27i Decoding Computer circuitry to “lock-up” (see Lock-Up under Trouble Shooting in “Appendices”).
While the Wadia 27i supports all currently accepted transmission formats for digital audio, we recommend using the glass optical cable that is included in your accessory kit. Wadia Digital was the first company to use glass fiber-optic data transmission in digital audio. We have continually improved this format and believe that it offers the best, most consistent performance of all the available options.

In 1990, Wadia became the first company to identify clock jitter as a distortion in CD playback systems and we have been refining our jitter reduction technology ever since. ClockLink is the most effective jitter reduction technology to date.
We strongly recommend that you connect your Wadia 27i Decoding Computer directly to your power amplifier. Even if you purchased your Wadia 27i with the intention of connecting it through a preamplifier, we suggest that you experiment with direct connection to your amplifier. Many listeners are surprised by the improvement in performance over even the most expensive preamplifiers.

T U R N - O N S C R E E N : W hen p ower is turned on, the Wadia 27i will show the display screen, as shown below, for five seconds. SELECTING AN INPUT: Any of the six inputs on the Wadia 27i can be selected by pressing the Input Select key on the remote control. Each time the Input key is pressed, the next input is selected. For example, if Input 1 is currently selected, pressing the Input key on the remote control will advance to Input 2 and so on. After Input 6, the list will begin again with Input 1.
INVERTING ABSOLUTE PHASE: The Wadia 27i has the ability to invert absolute phase in the digital domain. Pressing the Phase Invert key on the remote control will cause the Wadia 27i to invert phase; pressing it again will switch the phase back to normal. Whenever the Phase Invert key on the remote control is pressed, the display will change to the Status Screen, as shown below. The Status Screen indicates whether the current signal uses pre-emphasis and whether the phase is normal or inverted.
Each of the Wadia 27i digital inputs can be configured to match your system requirements There are three configuration parameters for each input: 1. Configure Input Enabled or Disobled 2. Configure ClockLink On or Off 3. Configure Input Name ENTERING CONFIGURATION MODE All configuration changes are done in the Configuration Mode.
Each input can be configured as either enabled or disabled: Enabled: If you intend to use an input, configure it OS enabled. This allows the input to function normally. Disabled: If you do not intend to use an input, configure it as disabled. When an input is disabled, it will not be visible when using the input key on the remote control to select an input for listening. This saves you from having to scroll past unused inputs when selecting your source.
Each digital input on the Wadia 27i can be configured as either ClockLink On or ClockLink Off. Clocklink On: Should be used only with ClockLink sources, such as the Wadia 27i. ClockLink Off: Should be used with all non-ClockLink sources. To change the ClockLink configuration for any input, press the Enter key repeatedly until the Configure ClockLink Screen for the desired input is displayed. The picture below shows the Configure ClockLink Screen for Input 2 showing Clocklink On.
Each input can be named for easy identification of your digital sources. For example, if you have a Wadia 270 connected to Input 1, you can create a custom input name so that when Input 1 is selected, the display reads: “Wadia 270”. To name an input, begin by pressing the Enter key repeatedly until the Configure Name Screen for that input appears.
To erose a disployed character, replace it with a new character or with a blank space. To insert a blonk space, use the Volume Up or Down key to scroll through the list of available characters until a blank space is displayed. Then press the Track Forward or Track Back key to move to the next character you wish to change. Below, the name “Wadia 270” has been selected, and a single blank space inserted to erase on extra character.
LOCK-UP If the Wadia 27i experiences a powerful static shock or sudden AC surge, it is possible to “lockup” the computer circuitry. A locked-up computer may result in erratic display, no output, and no response to remote commands. If your Wadia 27i should lock-up, unplug the AC cord. Wait at least 30 seconds before plugging the unit in again. If the unit still does not operate normally, contact your dealer, THIS AGREEMENT SETS FORTH TERMS AND CONDITIONS FOR THE DigiMaster SOFTWARE.
To get the best performance from your Wadia 27i Decoding Computer, ond for your own safety, please read and follow these important safety instructions. 1. Before operating the Wadia 27i Decoding Computer please read all of the operating and sofety instructions. 2. Never place the Wodia 27i Decoding Computer near heat sources such as radiators, fireplaces, stoves, or other appliances that produce heot.
