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
• 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 physical connections to be
defined (see
• 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 second example below; Net inputs are defined according to
chapter
• To make things easier :-) different systems may act as star system simulta-
neously; 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.
Hard-wired connection between two SCores; for these, MADI, ADAT, AES/
EBU, or even analog connections may be used.
Connection between two SCores running on a hard-wired Physical Con-
nection; may be defined as static (permanently reserved) or dynamic (used
by the system only as long as required). For Net Inputs, only static Logical
Connections are allowed.
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.
Object on the Source System that has specified a local source (e.g. input,
master, external PFL input, monitoring source, etc.).
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.).
A Net Consumer is called active as long as it is using the allocated Net Source.

is active if the corresponding Net Consumer is:
assigned to a channel strip, or selected as a monitoring
source, or assigned to a logical output via output routing
selected as a monitoring source
switched to at least one PFL bus
switched to at least one talkback destination
