Figure 3-19: S/PDIF on RCA & EIA-J. Connectors 1-3 on each card accept digital audio conforming to the
75Ω S/PDIF digital interface standard (via 75Ω cables equipped with
RCA-type connectors) from a digital satellite receiver, compact disc,
DVD or other digital source component. Connect the 75Ω S/PDIF
output of your source component to either of these inputs of the
Nº40, using a high quality 75Ω cable.
Connectors 4-5 on each card accept digital audio in the EIA-J optical
(sometimes called “Toslink™”) digital interface standard from a
digital satellite receiver, compact disc, laserdisc, DVD or other digital
source component. Connect the EIA-J digital output of your source
component to the EIA-J input of the Nº40 using a high quality EIA-J
optical cable. Keep track of which source components are plugged
into which connectors on the rear panel of the Nº40, either by
keeping a simple list (for example,“DSS receiver – Slot 6, Connector
4”) or by making a note on the Hookup Chart at the end of this
manual.
Audio RZone
Expansion
As shipped from the factory, slots 8 and 9 are normally empty
except for a blank piece of metal that covers the opening. These
slots can be used for the audio portions of additional Remote or
Record zones (“RZones”) immediately, should you require them.
The RZones are counted from right to left; hence slot 8 is reserved
for RZone 4, and slot 9 is reserved for RZone 3. This is shifted one
slot over from the arrangement on the video processor, since the
audio processing and system communications card occupies slot 12
(see below).
As an alternative to their application for RZone use, slots 8 and 9
can instead be used for additional input cards, should they be
needed.
Audio RZones 1 & 2
As shipped from the factory, slots 10 and 11 are normally used
for the audio portions of the two standard Remote or Record
zones (“RZones”).
Figure 3-20: Audio RZones. The RZones are counted from right to left; hence slot 10 is
reserved for RZone 2, and slot 11 is reserved for RZone 1. This is
shifted one slot over from the arrangement on the video proces-
sor, since the audio processing and system communications
card occupies slot 12 (see below).
Each card includes two single-ended analog output pairs on
custom-designed RCA connectors, as well as an S/PDIF digital
output on another RCA connector. Each card also includes two
SHARC DSP chips so it can do real-time decoding and downmix
to two channels of multichannel source material. Because of
this feature, you always have access to all your source material,
regardless of format, from a remote location. You can also make
a two-channel recording of multichannel material.
