240watts power amp:
In this configuration, zone1 selected sources will always be amplified by the PA2240BP channel 2 ampli-
fier. Zone 2-6 selected music sources will be amplified by the MA246 internal power amplifier. During
paging, the zones that must hear the paging messages are automatically disconnected from the MA246
internal amplifier and will be switched to the PA2240BP channel 1 amplifier. The internal MA246 power
amplifier will continue to play the music in the non-paged zones.

*Selective paging without any BGM in any zone is possible using the MA246(R)(MR) only, however,
in this case, you will have to turn the zone 2 to 6 front volume control to the off position.
In case a zone is being paged, the MA246(R)(MR) will bypass the volume control, causing the paging
message to be heard in the selected zone(s).
If you want BGM and selective paging without music interruption in the non paged zones, please use an
external paging amp (PA240P, PA2240P…).
From the factory, there is no wire bridge as shown in the picture. That’s because we want to encourage
you to use the MA246 as a switching centre in high quality BGM and paging systems where all zones are
individually pageable without interrupting the BGM in the non paged zones.
Most mixing amps from other brands don’t offer you this luxury.
Wire bridge in case of standalone use.
