12.3. Priority
A priority circuit has been inserted in order to
softening one or more setted input channels by
the priority control in accord with the system
requirements.
Internal jumpers are provided to assign muting of
the channels independently. From the factory,
muting is assigned to all input channels.
The figure Fig6. shows the instructions to assign
the muting of the channels.
A Normally Open input is available on the Remote
RJ45 socket (26) and also on the Priority 2 pole
phoenix-type connector (27) for the connection of
paging microphone with priority control or to be
controlled from external devices.
The Priority function could active the chime if
C714 Din Don optional card is used.
The figure Fig6. shows the C714 insertion
operation and level control.
NOTE: To avoid frustration, check this section BEFORE installing your mixer in the rack!
NOTE: Fix the connection by silicon glue after the optional cards insertion
