DESCRIPTI ON
4.1 Introduction
This section contains the functional descriptions of the major circuit cards
which can comprise the configuration of the Jaguar Audio Switchers (both
analog and digital versions). Please note that your Jaguar Audio Switcher
configuration may or may not contain all of the listed circuit cards. The cir-
cuit cards described in this manual sections are as follows:
•
Backplane
•
PS130 Power Supply
•
Single Reference Interface Card
•
64X32 Analog Audio Matrix Card
•
64X32 Digital Audio Matrix Card
•
Standard Output Card
•
Optional Analog Output Combiner Card
•
Optional Output Monitor Control Card
4.2 Backplane
The Jaguar Audio Backplane is responsible for providing passive distribu-
tion of the audio input signals to the audio matrix cards and for providing
distribution of the audio output signals to the standard output cards or the
optional output combiner cards. The backplane is also responsible for dis-
tribution of power from the power supplies to the Jaguar Audio Frame's
circuit cards and to the chassis fans. An additional function of the
backplane is to distribution control and communication signals to and from
the matrix cards, monitor control card (if installed), and control ports. The
power supply alarm signals and the matrix card alarm signals are also dis-
tributed by the backplane. The backplane are provides the passive distri-
bution of the reference input signals (sync signals). Binary coded DIP
switches on the backplane allow the selection of level, input, and output
codes for both the matrix "A" and matrix "B" audio matrix cards.
