6.5.20 I/O Sharing (Option)
I/O sharing allows accessing any signal (input, master, PFL, monitoring, etc.)
of one system by another one within the same controller network. When con-
necting several systems, some additional things must be considered during
configuration:
•
Hard-wired (“physical”) connections
between the SCores (MADI, ADAT,
AES/EBU, or even analog) must be established.
• These
physical connections
must be defined within in the system, because
the system just needs to know which outputs and inputs are linked through
hard-wired connections. This is performed in the configuration tool of the
target
system ( see chapter 6.5.20.1 ).
•
Logical connections
may either be defined as
static
(i.e. permanently reserved
for a certain signal) or
dynamic
(i.e. used by the system only as long as
required, which is more economical).
• A simple point-to-point configuration called “single-step I/O sharing” (as
shown in the first example below) only needs
logical connections
to be defined
( see chapter 6.5.20.2 ).
• In larger, “two-step I/O sharing” configurations,
Net inputs
represent objects
in the star system that provide signals (e.g. Logical Input A) from the source
system to the target systems connected to the star system, as shown in the sec-
ond example below; Net inputs are defined according to
chapter 6.5.20.3 .
• To make things easier :-) different systems may act as star system simultane-
ously; in the second example below, Target System 3 also acts as a Star System
by providing the Logical Input B of the (pale) Source System 7 to Star System
2 – which, in this case, acts just as another Target System. In other words:
Each system may be Net Source, Star, and Net Consumer system at the same
time.
Glossary: Physical Connection
Hard-wired connection between two SCores; for these, MADI, ADAT, AES/
EBU, or even analog connections may be used.
Logical Connection
Connection between two SCores running on a hard-wired Physical Connec-
tion; may be defined as
static
(permanently reserved) or
dynamic
(used by
the system only as long as required). For Net Inputs, only static Logical Con-
nections are allowed.
Logical Input
The term Logical Input not only comprises the audio signal of this input but
also its signal processing parameters, such as EQ, filters, dynamics, etc.
Net Input
Object on the Star System that is provided to other systems connected to the
Star System.
Net Source
Object on the Source System that has specified a local source (e.g. input,
master, external PFL input, monitoring source, etc.).
Net Consumer
Object on the Target system to which a mono or stereo signal must be assigned
(e.g. input, master, external PFL input, external monitoring source, etc.).
Net Consumer Active
A Net Consumer is called active as long as it is using the allocated Net
Source.
Consumer Type: is active if the corresponding Net Consumer is:
Net Logical Input
assigned to a channel strip, or selected as a monitoring source, or
assigned to a logical output via output routing
Net Ext. Monitoring Source
selected as a monitoring source
Net Ext. PFL
switched to at least one PFL bus
Net Talkback
switched to at least one talkback destination
