2) Connecting multiple MPX
When multiple paging microphones are required in your system, cascading can be
done by connecting them in parallel on the databus, and connecting it to the ‘PAGING’
RJ45 connector on the MTX as shown in below diagram.
The ARJ03P junction box can be used for easy connectivity of multiple paging
consoles on one databus.

Configuring the MPX
1) Configuration of one MPX
When only one MPX is connected, no configuration is required. After connected the
MPX to the matrix as shown above, the system is ready for operation.
2) Configuration of multiple MPX
When multiple MPX are connected, the paging is priority based and priority
settings are needed to be made. An unique address should be assigned to every
MPX, whereby the lowest address ‘001’ will have the highest priority. When an
announcement is being made, and another speaker with higher priority requests for
an announcement, announcements with lower priority will be interrupted.
Priority settings should be made in the MTX web-based interface under ‘Setup’ >
‘System Configuration’ > ‘Paging’. In this screen, the address for the corresponding
microphone can be selected. After selected, the ‘Set Address’ button should be
pressed and subsequently the PTT LED’s on all MPX will start blinking. After pressing
the PTT button, the address will be assigned to the corresponding MPX microphone.
