Choosing a Digital Cable
While the Wadia series 9 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 series 9 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 series 9 Decoding Computer System, both digital and
analog, use the standard audio pin configuration:
• Pin 1 - Ground
• Pin 2 - Positive signal
• Pin 3 - Negative signal
