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
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.
In
response, they founded Wadia Digital
-
a company based on the philosophy of applying
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 pas
t 10 years:
l
First outboard Digital-to-Anolog converter
l
DigiMaster patented algorithm (filter
optimized for reproducing music)
l
First company to apply glass fiber-optics to home audio
l
First company to recognize jitter as a source of audible distortion
l
First to perfect digital volume control
l
First high-end CD player competitive with expensive separates
l
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.
We are proud to introduce the Wadia 27i
-
a breakthrough in sonic performance
and a strong statement of our years of dedication to music.
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.
Included in the carton, you will find an accessory kit that contains the following:
l
Four steel spiked feet with threaded studs
l Four steel coasters
l
Remote Control and batteries
l Glass Optical Cable
l RCA-to-BNC adapter
l AC power cord
v
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
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.
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.
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”).
Inputs and outputs can be safely connected to the Wadia 27i Decoding Computer either:
The
l
Before the unit is powered up
l
When the unit is in Relay-Mute mode (See “Mute Modes” in General Operation)
Wadia 27i Decoding Computer has six digital inputs:
Input 1:Glass fiber optical
Input 2:Glass fiber optical
Input 3:Coaxial with BNC connector
Input 4:Coaxial with BNC connector
Input 5:
AES/EBU with XLR type connector
Input 6:Plastic optical
TOSLINK
To connect a
digital source, install a digital cable between the digital output of that source and
a digital input of the Wadia
27i
.
The
Wadia
27i will automatically adjust to the sampling rate of any standard
32K,
44.1 K, or 48K
digital audio format.
v
Input I is factory configured for ClockLink. Using a non-ClockLink source connected to a ClockLink
input results in sonic
degradation
To disable ClockLink see "Configuring Inputs."
