Avoid allowing static shocks to be applied to the inputs or
oufputs.
To prevent static shocks,
touch any grounded surface, such as the Wadia 270 chassis, before connecting or removing
a cable. It is
unlikely
that
a
static
shock
will
damage the unit, but it may cause he Wadia 270
Compact Disc
transport
circuitry
to
“lock-up” (see
Lock-Up
under Trouble Shooting in
Appendices).
While the Wadia 270 CD Transport supports all currently accepted high-quality transmission
formats for digital audio, we recommend using the ST glass-optical cable that is included
in your accessory kit or another high-quality ST glass-optical cable.
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
* These
lower quality formats are not supported by the Wadia 270.
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 out-perform
a poorly-implemented glass-optical system.
We recommend that if you are using a coaxial
S/PDIF
connection, have the cable terminated
with a BNC connector. This will provide higher performance than an RCA connector.
Your Wadia 270 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.
Connect your chosen cable from the appropriate digital output on the Wadia 270
to the corresponding digital input on your Decoding Computer.
