Wadia Digital 830 - Manual (Page 10)

For maximum performance, we recommend using an ST glassoptical cable, which can be
purchased from your Wadia dealer.
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. ST-type Glass optical (as implemented by Wadia, with high quality glass-optical cable)
2. AES/EBU using XLR connector
3. Coaxial S/PDIF cable using BNC connector
4. Coaxial S/PDIF 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 S/PDIF cable
can out perform a low-quality AES/EBU cable. A high-quality AES/EBU cable may outperform a
poorly-implemented glass-optical system
If you are using a coaxial S/PDIF connection we recommend having the cable terminated with a
BNC connector. This will provide higher performance than an RCA connector. Your Wadia 830
input or output kit comes with an RCA/BNC adapter that can be used for experimentation
between different types of coaxial S/PDIF cables.
Again, we highly recommend that you take advantage of your dealer’s experience and, most
importantly, trust your ears,
Using the digital cable of choice, connect the appropriate digital input or output to the
outboard component.
The Wadia 830 can be equipped with this card to allow it to interface with the PHAST
component control and home automation system. For more information on this remarkably
powerful and flexible system, contact your Wadia dealer.
