Introduction
Paging microphone for MTX
The MPX microphones are specifically designed to be used in combination with the
MTX Multi-Zone audio matrix system. They come in two different versions with four
and eight zone selection buttons, offering a plug-and play solution for corresponding
MTX matrix systems.
The construction is made of weighted ABS material and finished with an acrylic top panel.
The buttons are integrated using the capacitive touch principle without any mechanically
moving parts. Selection & status LED’s are integrated below the acrylic surface, giving
an indication of the selected zones and databus status. Besides the zone selectors, quick
operation is allowed through the Select & Clear all buttons, while the push-to-talk (PTT)
button should be pressed during the announcement.
An integrated chime tone is heard before any announcement. Announcements can be
made to the integrated pipe-neck microphone with a cardioid pickup pattern which can
be tilted to the desired angle.
The microphone should be connected to the matrix system using the fixed cable with a
length of 2 meters. The distance can be extended to a maximum length of 300 meters,
using standard CAT5E (or better) twisted pair cabling. Cascading of multiple paging
stations is made possible using the priority-based (user-configurable) databus, when
using additional junction boxes ARJ03P or CP45ARJ.
