DI GI TAL  
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 Minneapolis-  
based 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.  
Disappointed by the sound of early CD players, they examined the designs and found them  
to be unsophisticated compared with the technology available in other areas of digital design.  
a company based on the philosophy of applying  
In response, they founded Wadia Digital  
-
advanced technology to improve the performance of digital home entertainment equipment.  
Wadia's first product, the Wadia 2000 Decoding Computer, was a breakthrough.  
For many listeners, it proved the viability of Compact Disc as a musically involving format.  
Ever since, Wadia has continued to develop on the original technology; refining, listening  
and improving along the way. Since the Wadia 2000, new generations of even higher  
performance designs have been introduced. Each step of the way, Wodia has raised  
the standard for performance of CD playback.  
Here is an abbreviated list of the technological innovations the Wadia engineers  
have pioneered over the past 10 years:

First outboard Digital-to-Anolog converter  
DigiMaster patented algorithm (filter optimized for reproducing music)  
First company to apply glass fiber-optics to home audio  
First company to recognize jitter as a source of audible distortion  
First to perfect digital volume control

First high-end CD player competitive with expensive separates  
ClockLink proprietary jitter reduction technology  
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.  
Now past our tenth year, Wadia continues to redefine the limits of digital music playback.  
a breakthrough in sonic performance  
We are proud to introduce the Wadia 27i  
and a strong statement of our years of dedication to music.

Four steel spiked feet with threaded studs  
Four steel coasters  
Remote Control and batteries  
Glass Optical Cable  
RCA-to-BNC adapter  
AC power cord  
Do not tip the unit onto the back panel. This can damage input and/or output connectors.  
Place the Wadia 27i on a non-marring surface; screw one of the spiked feet into the threaded  
hole in each corner of the bottom panel.  
Position the Wadia 27i where you would like it to reside in your system. We recommend  
choosing a solid, non-resonant, level surface for best performance. If this surface is susceptible  
to damage, place one of the steel coasters under each spiked foot.  
You can adjust the spiked feet so that the Wodia 27i sits firmly on all four feet. Place your  
hand on top of the unit ond gently rock it back and forth. If the unit moves, notice which foot  
is raised, then adjust it by screwing it down from the chassis (clockwise looking from the top  
of the unit). Repeat until the unit is stable.  
To install the batteries, remove the back cover by removing the screws found on the bock  
of the remote. Insert the batteries as indicated on the battery holders.

Q
CHECK  
HERE1  
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. If the voltage specified is different from your AC voltage, contact your Wadia dealer  
USING AC LINE CONDITIONERS  
In most cases, best performance is obtained when the Wadia 27i is plugged directly into the  
wall outlet using the AC power cord provided. The Wadia 27i employs extensive power-line  
filtering and noise suppression technology. It should not be necessary to use power conditioners  
or after-market power cords. If you wish to experiment with any of these devices, work closely  
with your dealer and most of all, trust your own ears.  
USING A “SURGE PROTECTOR”  
Although the Wadia 27i will resist significant voltage spikes, it can still be damaged by  
extreme voltage overload such as a lightning strike. Such damage is not covered by the  
warranty. In some circumstances, a “surge protector” can help prevent this type of damage.  
However, surge protectors often degrade sound quality. Each Wadia owner must weigh the  
protection offered by a surge protector against the sonic degradation.

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”).  
Inputs and outputs can be safely connected to the Wadia 27i Decoding Computer either:

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.  
Based on our experience, here is a list of digital interface methods in descending order  
of performance:  
1 .  
Glass optical (as implemented by Wadia)  
2. AES/EBU using XLR connector  
Coaxial cable using BNC connector  
3.  
4. Coaxial cable using RCA connector  
5. TOSLINK plastic-optical cable  
The quality of any of these transmission methods depends on the quality of the cable and  
the sophistication of the transmitter and receiver. For example, a high-quality coaxial cable  
can outperform a low-quality AES/EBU cable. A high-quality AES/EBU cable will outperform  
a poorly-implemented glass-optical system.  
We recommend thot if you are using a coaxial cable, have the cable terminated with a BNC  
connector. This will provide higher performance than an RCA connector. Your Wadia 27i comes  
with an RCA/BNC adapter that can be used for experimentation between different types of  
RCA terminated coaxial cable.  
Again, we highly recommend that you take advantage of your dealer’s experience and, most  
importantly, trust your ears.  
All XLR-type inputs and outputs on the Wadia 27i Decoding Computer, both digital and analog,  
use the standard audio pin configuration:  
Pin 1 Ground  
Pin 2 Positive signal  
Pin 3  
Negative signal

ClockLink is a proprietary Wadiadesigned system that improves sonic performance by greatly  
reducing clock jitter. 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.  
In most CD playback systems, the system master clock is located at the transport. As the clock  
signal is transmitted to the digital-to-analog converter, it is contaminated with noise. This noise  
results in uneven time intervals between output pulses from the DAC. This inconsistency causes  
measurable and audible distortion.  
With ClockLink the system master clock is located very close to the DAC chips in the digital-  
to-analog converter system. This simplifies the path through which the clock signal must travel,  
minimizing the opportunity for jitter to contaminate the clock signal. This approach offers  
lower jitter than ony previous jitter reduction method, and a commensurate improvement  
in sonic performonce.  
The Wadia 27i also uses improved clock circuitry for non-ClockLink sources. This circuitry results  
in noticeable sonic improvements with non-ClcokLink digital sources.  
If you are using a digital source equipped with Clocklink, such as a Wadia 270 in a Clocklink  
mode, an ST-type glass fibercable must be instolled between the Wadia 27i ClockLink Output  
and your CD transport Clocklink Input.  
This cable is installed as shown below.

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. If you would like more information about getting best performance from a system  
without a preamplifier, contact your Wadia dealer.  
To connect your Wadia 27i to a power amplifier, ensure that your power amplifier is turned off,  
then connect your analog interconnects from the Wadia 27i balanced or unbalanced analog  
outputs to the amplifier’s inputs.  
While the Wadia 27i Decoding Computer was designed to be used without a preamplifier,  
it will provide excellent operation in a conventional system with a preamplifier. Simply connect  
the analog outputs from the Wadia 27i to a pair of linelevel inputs on the preamplifier.  
When using a preamplifier, disable the Wadia  
maximum volume.  
volume control by setting it to its  
Best performance is obtained when the Wadia Digital Volume Control is operated close to its  
maximum level. If you find that your critical listening occurs with the volume lower than 65 on  
the display, then it may be advantageous to attenuate the output. This is done by manipulating  
a set of internal switches. If you would like to change the output level, consult your dealer.  
The Wadia 27i output level is factory set at 4.2 volts which will accommodate the most common  
range of system sensitivity without needing adjustment.

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  
When selecting an input, disabled inputs will be skipped (see “Configuring Inputs”).  
When the Input key is pressed, the display will change to the Input Screen, as shown below.  
The Input Screen displays information about the input currently selected, including the input  
name and sampling frequency. If no signal is detected on the selected input, the display will  
indicate this by showing “No Data”.  
ADJUSTING THE VOLUME: Whenever the Volume Up or Volume Down keys on the  
remote control are pressed, the volume on both channels will be increased or decreased by  
an increment of 1 on the display screen. The range of the volume display is from 0 to 100,  
with each step representing 0.5 dB change in volume. During normal operation, the Volume  
Screen, as shown below, is the default screen.  
ADJUSTING THE BALANCE: Relative volume of each channel can be adjusted via the  
balance control keys on the remote. Each time one of the balance keys is pressed, the volume  
on that channel is increased relative to the other by an increment of 0.2 on the display. As the  
balance is adlusted, one channel or the other is decreased alternately. This corresponds to  
a
0.1 dB change as the overall volume level (the sum of the two channels) remains constant within  
0.1 dB. During balance adjustment, the display will change to the Balance Screen, as shown  
below, indicating the volume to 0.1 dB precision.  
Download from Www.Somanuals.com. All Manuals Search And Download.  
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.  
CHANGING BETWEEN DISPLAY SCREENS: During normal operation, the Wadia 27i  
display will switch between the display screens to show information about which functions  
are being accessed. For example, the Balance Screen will be displayed if the balance keys  
on the remote control ore pressed.  
Pressing the Enter key will advance through the display screens in the following order:  
1. Volume Screen  
Brightly-illuminated Volume Screen  
Balance Screen  
Input Screen  
2.  
3.  
4.  
5. Status Screen  
6. Configuration Screens (18 screens total, see “Configurafion” for more information)  
7. Back to the Volume Screen  
TURNING DISPLAY ON/OFF: By pressing the Display On or Off key, the Wadia 27i  
display can be turned off completely. Several of Wadia’s transports will respond to the same  
key, allowing you to control both displays at the same time.  
If the display is turned off, it will reappear for five seconds whenever a Wadia 27i function  
key on the remote control is pressed.  
MUTE MODES: The Wadia 27i Decoding Computer has two Mute Modes that are  
automatically engaged under different circumstances.  
DSP-SOFTWARE MUTE: When the Mute key is pressed on the remote control, the  
Wadia 27i Decoding Computer’s DSP engine transmits a stream of zero signal level  
samples to the DAC section, which results in zero output.  
OUTPUT-RELAY MUTE: The Wadia 27i Decoding Computer has mute relay connected  
between the positive and negative outputs. When this relay is engaged, it connects the  
positive output to the negative output, reducing the output to zero. This relay, which  
produces an audible click when it engages or disengages, is not in the music signal path.  
The mute relay is engaged:  
l
When the Wadia 27i Decoding Computer detects AC input level below its minimum  
operating range  
l
l
Each time the Wadia 27i Decoding Computer is powered-up  
When the volume control is set to zero AND the Mute key on the remote control  
is pressed.  
When the Wadia 27i is in either Mute Mode, the Volume Screen will indicate this by  
displaying the word, “MUTE.”

Each of the Wadia 27 digital inputs can be configured to match your system requirements  
i
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. To enter Configuration  
Mode, press the Enter key repeatedly until the display shows the configuration screens  
All of the configuration screens have the word “CONFIGURE” on the top row. Each input has  
three configuration screens, one for each of the three configuration parameters listed above.  
As you repeatedly press the enter key, the Wadia 27i will scroll past the configuration  
screens for each input, first showing the screens for input 1, then Input 2, and so on.  
SAVING CONFIGURATIONS  
Any time you change a configuration setting, it is automatically saved in volatile memory  
where it will be stored unless the AC power is turned off. If the AC power is turned off, the  
Wadia 27i will revert to the last configuration settings that were saved in non-volatile memory.  
If none have ever been saved to non-volatile memory, the Wadia 27i will revert to the factory  
settings. If you wont to save your configuration settings in non-volatile memory so that they will  
remain even if the AC power is turned off, use the Mute key, as described below, when exiting  
the Configuration Mode.  
EXITING CONFIGURATION MODE  
There are three ways to exit the Configuration Mode:  
Mute: Pressing the Mute key will save all new configuration settings in non-volatile memory  
and exit the Configuration Mode.  
Time-out: If you do not press any key for approximately 16 seconds, the Wadia 27i will exit  
the Configuration Mode.  
Scroll out: If you continue to press the Enter key over and over again, you will scroll past all  
the configuration screens, out of Configuration Mode and back to the volume or status screen.  
If you leave the Configuration Mode by timing out, you must press the Input Select key to make  
the new configuration settings take effect. If you leave Configuration Mode without pressing  
Mute, any changes will be stored in volatile memory where they will be lost if AC power is  
turned off.

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.  
In addition, if an input is configured as disobled, the Configure Clocklink and Configure  
Name Screens for that input are not available when scrolling through the configuration  
screens.  
There is no sonic advantage to disabling the unused inputs. The Wadia 27 and the original

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. Shown below is the Configure Input Name Screen for Input 1:  
Pressing either the Volume Up or Down key or Track Forward or Back displays the cursor,  
which appears OS an underscore, indicating which character is being modified.  
The Volume Up and Volume Down keys allow you to scroll through a character list to select the  
desired letter or number. The Track Forward and Track Back keys move the cursor right or left  
to the next or previous character.  
All upper and lower case letters are available, as well as numbers and a blank space.  
The blank space character is located in the character list between the number 0 and the lower-  
case letter “z.” Below, the letter “W” has been selected:
