Forced 4-Wire Connection
Producer System Status
Document generated: 06.08.14
When assigning the (net) logical codec input to a fader strip on the desk
surface, the return line is connected to the codec's patch output immediately,
and the key will then be bright. This connection type is automatically
established if the Codec Return Activation is set to Connect Always.
If the return line should be used by another system already, it is automatically
taken away from the other system without further user action. A user warning
is created on the other system's main screen and in the log file of the central
log screen.
Note: Codec return line control is currently not supported by the user GUI. Opera-
tion is possible with the hardware controls only, as described above. How-
ever, codec return lines may be remotely connected and disconnected in the
Routing - Output page of the producer system, i.e., the system to which the
codec is physically connected.
The three different return line control modes described above can, of course,
only work out properly if the producer system is operative. If this should not
be the case, the following restrictions must be considered:
• Codec return lines can be (automatically or manually) activated only while
the producer system is running.
• If the producer system shuts down, the status of all 4-wire connections is
forced to 2-wire connection.
• If the producer system starts up while a net logical input of the consumer
system is in 2-wire connection status, this status is retained.
