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.
