When connecting loudspeaker paging to an IPO Partner Edition 6.1 analog extension port, can I connect directly to an amplifier from the port defined as the Loudspeaker extension to a Lo Z input on the amplifier? If I need to connect to a Hi Z input, can I just use an impedance matching transformer from the port to the amp? I read previous tips regarding a regular IPO stating that a UPAM is not needed unless coming off an analog trunk port ( and wanted to confirm it would be the same on the IPO Partner Edition. Thanks for the help.
