Choosing a

Digltal Cable

Best performance is obtained when operating the Wadia Digital Volume
Control in the top half of its range. If needed, the maximum output level

of your Wadia 860 can be adjusted to match the overall sensitivity of your
system so that the critical listening will take place with the volume control
operating in the top half of its range.

The maximum output level of the Wadia 860 Compact Disc Player is

adjustable by means of a set of internal switches. The Wadia 860 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 50 on
the volume display, then it may be advantageous to use a different setting.
The output level is not user adjustable. If you would like to change the

output level, consult your dealer.

Your Wadia 860 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 type connector

The Wadia 860 will automatically adjust to the sampling rate of any of the

standard digital audio formats.

While the Wadia 860 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, with high quality glass optical cable)

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 860 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 860 Compact Disc Player,

both digital and analog, use the standard audio pin configuration:

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