3 DIGITAL INPUTS 1-6
Please remember to make a note of what sources you connect to which
inputs. You will need to set up the relationships between front panel but-
tons and rear panel connectors later, in the setup menu system. For now,
you can connect any source to any compatible connector—just keep a list
of what-goes-where. (Just such a list is waiting for you later in this manual.
You might want to copy it in order to keep the original clean for future
use.)

Digital Input 1 accepts digital audio in the EIAJ optical (sometimes called
“Toslink”) digital interface standard from a digital satellite receiver, compact
disc, laserdisc, DVD or other digital source component. Connect the eiaj
digital output of your source component to the EIAJ input of the Digital Sur-
round Decoder using a high quality EIAJ optical cable.
Digital Inputs 2-5 accept digital audio conforming to the 75Ω S/PDIF digital
interface standard (via cables equipped with RCA-type connectors) from a
digital satellite receiver, compact disc, laserdisc, DVD or other digital source
component. Connect the 75Ω S/PDIF output of your source component to
either of these inputs of the Digital Surround Decoder, using a high quality
75Ω cable such as Madrigal MDC-2.
Digital Input 6 accepts digital audio in the professional 110Ω AES/EBU digital
interface standard (via a cable equipped with XLR-type connectors) from a
digital satellite receiver, compact disc, laserdisc, DVD or other digital source
component. Connect the AES/EBU digital output of your source component
to the AES/EBU input of the PDSD using a high quality 110Ω AES/EBU cable
such as Madrigal MDC-1.
The pin assignments of these AES/EBU XLR-type female input connectors are:

Pin 1: Shield
Pin 2: Digital + (non-inverting)
Pin 3: Digital – (inverting)
Connector ground lug: chassis ground
These pin assignments are consistent with the standards adopted by the
Audio Engineering Society and the European Broadcast Union. Refer to the
operating manuals of your digital sources to verify that the pin assignments
of their output connectors correspond to the Digital Surround Decoder. If
not, wire the cables so that the appropriate output pin connects to the
equivalent input pin.
4 REMOTE OUTPUT (ANALOG & DIGITAL)
By connecting the balanced (analog) remote outputs in this module to the
bal/aux input on the PAV, all PCM (normal digital, not Dolby Digital nor
DTS) sources connected directly to the Digital Surround Decoder will be
available for distribution to either the PAV’s remote zone or its record path.
When you select (on the PAV) such a digital source for either the remote
zone
or the record path, the PDSD will pass that digital signal to this mod-
ule, where it will be converted to analog and forwarded to the PAV, which
will in turn send the signal out its appropriate analog outputs. Note that
sources such as AC-3 and DTS are not available at this two-
channel analog output. (They are, however, available in their original
digital form at the digital output; see below.)
