Connecting & Configuring the MPX
Depending the number of connected MPX paging microphones to one matrix, the
connection and configuration should be done in an appropriate way.
When only one MPX is connected to a system, it can simply be plugged and used
without requiring any further configuration. When multiple MPX microphones are
connected to a system, cascaded connections and priority configurations should be
made as described in this chapter.
The maximum distance from the beginning of the databus to the last device is limited
to a total cable length of 300 meters. The supply voltage for the MPX is delivered over
the twisted pair cabling and the voltage level on the MPX side should be at least 15
Volts. When the voltage drop on the MPX side is lower than 15 Volts, the system won’t
work properly and an ARJ03P junction box with external power supply needs to be
applied.
Connecting the MPX
1) Connecting one MPX
When only one paging microphone is required in your system, the MPX can be directly
connected to the ‘PAGING’ RJ45 connector on the MTX as shown in below diagram.
