Wadia 9 Series Decoding Computer System Owner’s Manual

Choosing a Digital Cable

While the Wadia 9 Series Decoding Computer system 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

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. We recommend

that 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

9 Series Decoding Computer system 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 9 Series Decoding Computer system,

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

• Pin 1 - Ground

• Pin 2 - Positive signal

• Pin 3 - Negative signal
