Professional installers will also appreciate the possibility to use an external amplifier as a paging amp.
Suppose zones 2 and 3 should not receive paging messages, meaning there should always be
background music. In this situation, the installer can use an external amplifier for paging. When a
paging call is sent out, zones 2 and 3 will stay connected to the internal amplifier and will continue to
receive background music. The other zones will hear the paging message. The MA246 will disconnect
these zones from the internal amp and will send the paging message to the external amp. When
paging is finished, these zones will be switched back automatically to the internal amp. To learn more
about selective paging with the MA246, check page 6 of this technical sheet.

When required, it is even possible to use a 2-channel amplifier (e.g. the PA2240BP) as external
amplifier, with one channel assigned to power zone 1 of the MA246, while the second channel of the
external amplifier is used to power paging messages.
