7. Priority function / setting options
7.1 mixing mode (factory preset)
•
inputs 1, 2, 3 and AUX can be mixed
• in addition: activating a priority input (DIN-connector or Remote Control-connector) attenuates the
AUX-signal
• activating a channel’s priority function the routing and zone level settings are maintained, i. e. if one
of the outputs is switched off it stays off and if the volume is set to a low level, this setting is remained
• the master volume control is not bridged
• gong, alarm or voice messages get absolute priority – all inputs are attenuated and all outputs are
set to their maximum volume
• this setting does not permit the use of the MT2005
7.2 priority mode
•
to prepare the unit for the use of the priority function you have to insert the jumper J301
• several other jumpers deliver different results of the priority function
• if only J301 is inserted, the priority sequence is as follows: voice messages, alarm, gong, input 1,
input 2, input 3 (cascade priority)
• MT 2005 paging stations are always in block priority amongst each other
• the priority status of an input is determined by the priority-input through the DIN-connector or through
the Remote Control-connector (contact to ground), or – with the MT2005 paging stations – it gets
internally generated
• when the priority mode is activated, the master volume control is bridged. A collective call is performed
and all zones are set to their maximum output level (exception: when a call is launched via an MT2005,
only the zones that are selected on the particular microphone terminal are set to maximum output,
all other zones are off.)
• activating a priority attenuater the AUX signal
7.3 further options of the priority mode
•
switching to block priority by inserting the jumper J302
• canceling the automatic pre-gong signal via J303
• inserting J304 sets input 1 to the highest priority – i. e. during an outgoing voice message, an alarm
or a gong signal, announcements can be made from input 1
• mixing the audio signals of the inputs 2 and 3 is possible when the jumper J305 is inserted (which of
course excludes the use of MT 2005 paging stations). Anyway, this status allows the fading of the
AUX signal by engaging the corresponding priority input which excludes priority reception.
• despite any priority operation it is possible to mix the audio signal of input 3 when the jumper J306 is
inserted. Anyway, this status allows the fading of the AUX signal via engaging the corresponding
priority input. Priority reception is not possible.
• Monitoring of the microphone terminals: depending on the number of MT2005 microphone terminals
connected, the ready-contact reports whenever a microphone terminal does not answer (not connec-
ted, faulty connection, function error). Setting via J307 and J308.
