2 S/PDIF (BNC) ELECTRICAL DIGITAL OUTPUT
This output provides the
digital audio signal ( DAS ) via cables equipped
with BNC-type connectors to the digital processor.
This output conforms to the Sony/Philips Digital Interface Standard
(S/PDIF), which calls for a 75
Ω
transmission of the DAS. Use a digital inter-
connecting cable specifically designed for the 75
Ω
S/PDIF standard, such as
Madrigal MDC-2 cable, when using this output. (In our experience, a BNC-
terminated S/PDIF cable has a slight advantage over the same cable termi-
nated with RCAs. This is probably due to the fact that a BNC connector has
a true 75
Ω
impedance, whereas RCA connectors cannot.)
3 S/PDIF (RCA) ELECTRICAL DIGITAL OUTPUT
This output provides the
digital audio signal ( DAS ) via cables equipped
with RCA-type connectors to the digital processor.
This output conforms to the Sony/Philips Digital Interface Standard
(S/PDIF), which calls for a 75
Ω
transmission of the DAS. Use a digital inter-
connecting cable specifically designed for the 75
Ω
S/PDIF standard, such as
Madrigal MDC-2 cable, when using this output.
4 ST OPTICAL DIGITAL OUTPUT (OPTIONAL)
When so equipped, this output provides the
digital audio signal ( DAS) , via
optical cable equipped with the ST-type optical connector (sometimes
called “AT&T”) to the digital processor. Your dealer can easily install the op-
tional ST input for you, should you require it. Please check with your dealer
regarding pricing and availability.
As delivered from the factory, the ST connection space in the rear panel of
the CDD is covered by a plastic plug. We have elected not to burden the
price of every CDD with the ST optical output for the simple reason that
the electrical interconnection standards (aes/ebu and s/pdif) provide supe-
rior performance when fully optimized.
If you are using a Madrigal-designed digital processor, we recommend us-
ing the aes/ebu connection for the best results; the two s/pdif electrical
connections follow closely behind aes/ebu. EIAJ is (unfortunately) the most
widely-used digital interconnection standard, yet offers the poorest perfor-
mance. We include it for compatibility reasons.
In some cases (with non-Madrigal products), the ST digital input of a par-
ticular digital processor may offer the best performance of the various in-
puts. In this case, your dealer can easily install the optional ST output for
you, should you require it. Please check with your dealer regarding pricing
and availability of the ST output kits.
5 EXTERNAL IR INPUT
The CDD incorporates an infrared repeater input to facilitate a wide range
of installation options. If desired, the CDD may be placed inside a cabinet
or outside the normal line-of-sight in the listening area, with the controlling
IR signal being relayed to the CDD by any of a number of commercially-
available IR repeaters.
