Choosing a
Digital 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 850 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 850 Compact Disc Player is adjust-
able by means of a set of internal switches. The Wadia 850 is factory set at
4-2 volts 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 850 Compact Disc Player can be retrofitted to include digital
inputs and/or outputs. Consult your dealer for information on this option.
If your Wadia 850 is equipped with the optional digital inputs,
the configuration is as follows:
Input 1: Glass-fiber optical
Input 2: Coaxial with BNC connector
Input 3: Coaxial with BNC connector
Input 4:
Plastic-optical
TOSLINK
The Wadia 850 will automatically adjust to the sampling rate of any of the
standard digital audio formats.
If your Wadia 850 is equipped with the optional digital outputs,
the configuration is as follows:
Output 1: Glass-fiber optical
Output 2: Coaxial with BNC connector
The digital output signal is active at all times when a CD is playing in the
transport.
While the Wadia 850 supports several 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. Coaxial cable using BNC connector
3. Coaxial cable using RCA connector
4.
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.
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. If you purchased the optional digital inputs or outputs, an
RCA/BNC
adaptor is provided. The adaptor can be used for experimentation
between different types of coaxial cables.
Again, we highly recommend that you take advantage of your dealer’s
experience and, most importantly, trust your ears.
