Peavey PageMatrix - Manual (Page 20)

3: To interpret the proprietary control data from the paging stations and convert it to
standard serial strings which can be forwarded to MediaMatrix.
Microphone signals from the paging stations are not acted upon by the PageMatrix Controller,
but are simply passed through the box as received. Any switching or routing is done within
MediaMatrix.
4.1.4. The MediaMatrix system and PASHA
Among many other tasks, the MediaMatrix system receives the analog audio from the Paging
Stations via the PageMatrix controller, converts it to digital and performs all processing of
those signals, including the routing of these signals to the various ÒzonesÓ. These routing
functions are accomplished by special PageMatrix devices within the systemÕs ÒView FileÓ
which are controlled from the PageMatrix Controller via PASHA.
4.1.5. Push-to-talk switchÐWhat happens?
1: Pressing a stationÕs zone preset button selects the configured zones in MediaMatrix.
2: When the push-to-talk switch is pressed, the PageMatrix Controller immediately sends the
proper serial command to the MediaMatrix Com port. (The serial command sent is pre
determined by the PageMatrix configuration file which has been downloaded and is
running in the controller.)
3: This serial command is interpreted by MediaMatrix (via PASHA) and ÒpressesÓ the
appropriate router buttons in the MediaMatrix view file to send the audio to the zone or
combination of zones selected by the paging station.
4: Audio passes to the zone(s) through MediaMatrix as long as the push-to-talk button on the
station remains pressed.
5: Functions such as paging priorities, signal source ducking, zone equalization, etc. are all
functions of the MediaMatrix system and are not directly acted upon by the PageMatrix
components.
4.1.6. Operation within MediaMatrix
Paging devices can be complicated systems consisting of multiple Òmixing routers.Ó For
example, programming a paging device which consists of 8 stations and 32 buttons requires
that a PASHA file be written addressing each of the matrix locations (256 parameters). Since
programming your own Pasha files would require extensive time, we have provided a variety
of view files and associated PASHA.INI files to simplify the task. We highly recommend you
use the files weÕve provided on floppy disk and edit them for your specific application.
