4.2 FEATURE DESCRIPTION
4.2.1 Crossmute
When a parallel console operator keys a microphone in the same room, the crossmute function mutes the receive
audio path of the other parallel consoles. This prevents any unwanted audio loops that could occur, causing a loud
squeal on the paralleled speakers.

Figure 5 Crossmute Function example.
Feedback may be avoided by muting the receive audio of the other consoles which are in parallel with a transmitting
console. This may be accomplished by connecting pins 1 and 8 of each of the consoles to be crossmuted as shown
in Figure 5. Pin 8 must be connected to provide a common ground. Figure 5 illustrates the connections between
consoles 1 through 3 that are in the same room and when one transmits, the receive audio on the other consoles will
be muted. Console 4 is off-site with no possibility of feedback, therefore, it is not connected and will not be muted.
Note: The intercom function will not work between crossmuted consoles.
