Figure 7-43 Local Advanced with a Property Selected
The following is a description of each option. Every option does not appear for every
combination of source and destination.
The possible options are described below.
7.11.1 Forced listen
A forced listen is a permanently enabled audio path between a source and a destination
that can only be interrupted by IFB/ISO calls. It does not have any association with a
selector key.
If panel eavesdropping is disabled for a panel, the forced listen is not effective until the
panel has at least one talk path set. Panel eavesdropping is enabled from the Advanced
Settings screen of Cards and Ports for the source port. Forced listen audio is routed from
the label on the left to the label on the top.
7.11.2 Blocked listen
If a listen is blocked between two ports then an audio path from that same source to that
destination cannot be set under any circumstances. This is primarily used as a safety
feature. For example, to prevent one studio’s program feed from being accidentally routed
to a destination in another studio.
