MTI DOC 91743-A1
CONNECTING A PAGE AMPLIFIER
When used in conjunction with a paging amplifier, the 91743 Digital Intercom Amplifier
supports paging over the intercom system. The maximum required power that can be sourced to
each paging zone is 60W. The “Page In” signal on the 91743 is an unbalanced microphone level
output which can be connected to the input of an external paging amplifier. The input of the
paging amplifier must be unbalanced. The “Page Out” signal on the 91743 should be connected
to the output of the paging amplifier. When the amplifier is in page mode, the output of the
paging amplifier is directly connected to the MTI speaker buss. This allows 25 or 70 volt paging
speakers to be used depending on the output of the paging amplifier. Typical page amplifier
hookups can be seen in the Appendix.
To connect a MTI 91743 to a paging amplifier:
1.
Connect two appropriately sized conductors to the “Page In” signals on the 91743.
2.
Connect the other end of the conductors to an unbalanced, microphone level input of the
paging amplifier.
3.
Connect two appropriately sized conductors to the “Page Out” signals on the 91743.
4.
Connect the other end of the conductors to the output of the paging amplifier.
