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 have been introduced and embraced by listeners around the world. Each step of the way, Wadia has consistently raised the standard for performance of Digital Audio playback.

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 CD player competitive with expensive separates

• First company to provide bit perfect digital audio output from the iPod

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.

Wadia is proud to introduce the Wadia 581se/781i CD Player, a breakthrough in sonic performance and value, and a strong statement of our years of dedication to music.

Installation and Set-up

Unpacking

Use care in unpacking your Wadia 581se/781i CD Player. Inspect it for any shipping damage and call your dealer immediately if any is found.

Do not plug your Wadia 581se/781i CD Player 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.

Accessories

Provided with the Wadia 581se/781i CD Player are the following accessories:

• AC power cord

• Four tip-toes with threaded studs

• Four steel coasters

• RCA/BNC adapter (only included with 581ise and 781i)

• Remote Control

• Two type AAA batteries

Do not tip the unit onto the back panel. This can damage input and/or output connectors.

Installing the Tip-Toes

With the unit still positioned on its side, screw one of the tip-toes into the bottom of each corner post.

Position the Wadia 581se/781i CD Player 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 tip-toe.

Connecting to Your System

CHECK

VOLTAGE

HERE

Check to make sure your Wadia 581se/781i CD Player has been manufactured for operation at your AC line Voltage. Attempting to use the Player at any voltage other than the specified on the rear of the unit may damage the unit. Damage caused by improper operation is not covered by warranty. If the voltage specified is different from your AC voltage, contact your Wadia dealer.

Connecting to AC Power

The best performance is obtained when the Wadia 581se/781i CD Player is plugged directly into the wall with the power cord provided. The Wadia has power conditioning, surge suppression and an extremely sophisticated overall protection scheme. It should not be necessary to use surge protectors power conditioners or aftermarket power cords, some of which may degrade the sonic performance. If you wish to experiment with any of these devices, work closely with your local dealer – and most of all, trust your own ears.

Connecting Directly to a Power Amplifier

Avoid allowing static shocks to be applied to the inputs or outputs. To prevent static shocks, touch any grounded surface, such as the Wadia 581se/781i CD Player chassis, before connecting or removing a cable. It is unlikely that a static shock will damage the unit, but it may cause the Wadia 581se/781i CD Player circuitry to “lock-up” (see Lock-Up under Trouble Shooting).

Inputs and outputs can be safely connected to the Wadia 581se/781i CD Player

1 Before the unit is powered up 2 When the unit is in Relay-Mute mode

We strongly recommend that you use your Wadia 581se/781i CD Player connected directly to your power amplifier. Even if you purchased your Wadia 581se/781i with the intention of connecting it to your preamplifier, we suggest that you try direct connection to your amplifier. Many listeners are surprised by the improvement in performance over even the most expensive preamplifiers.

To connect your Wadia 581se/781i CD Player to a power amplifier, ensure that your power amplifier is turned off then connect your analog interconnects from the Wadia 581se/781i analog outputs to the amplifier’s inputs.

Using with a Preamplifier

While the Wadia 581se/781i CD Player was designed to be used without a preamplifier, no compromises were made in its design that will prevent excellent operation in a conventional system with a preamplifier.

When using a preamplifier, set the Wadia 581se/781i CD Player volume control to its maximum level.

Optimizing the Output Level

Best performance is obtained when operating the Wadia Volume Control near the top of its range. If needed, the maximum output level of your Wadia 581se/781i CD Player can be adjusted to match the overall sensitivity of your system so that the critical listening will take place with the volume control operating near the top of its range.

The maximum output level of the Wadia 581se/781i CD Player is adjustable by means of a set of internal switches. The Wadia 581se/781i CD Player is factory set to accommodate the most common range of system sensitivity. If you find that your typical volume level during critical listening is below 65 on the volume display, it will be advantageous to use a different setting. To change the output level, consult your dealer.

Connecting to Other Digital Sources (Wadia 581ise/781i only)

The Wadia 581ise/781i CD Player is equipped with digital inputs which can accept digital signals from any of the established digital formats. (Input 1: Glass-fiber optical, Input 2: Coaxial with BNC connector, Input 3: Plastic-optical TOSLINK, Input 4: AES/EBU with XLR connector)

The Wadia 581ise/781i CD Player digital inputs will decode any word length up to 24-bit, and any of the standard digital audio sampling frequencies up to 96kHz.

Choosing a Digital Cable (Wadia 581ise/781i only)

While the Wadia 581ise/781i CD Player supports all currently accepted transmission formats for digital audio, we recommend using a high quality glass-fiber cable such as the one available from Wadia. 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 3 Coaxial cable using BNC connector 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.

If you are using a coaxial cable we recommend that you have the cable terminated with a BNC connector. This will provide higher performance than an RCA connector. Your Wadia 581ise/781i comes with an RCA/BNC adapter that can be used for experimentation between different types of 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 581se/581ise/781i CD Player, both digital and analog, use the standard audio pin configuration:

Pin 1 - Ground Pin 2 - Positive signal Pin 3 - Negative signal
