ZoneMaster 1250
¡¤ Our new ZoneMaster models are very similar in their feature sets, differing mainly in size and number of channels.
Looking for fewer channels? Try the 650, 450, or 250.
¡¤ Universal amplifier for applications from 50 to 200 watts
¡¤ 24 speaker connections (A and B outputs for all 12 channels)
¡¤ High current for stable operation at 2 Ohms
¡¤ Channel pairs are bridgeable for up to 200 watts @ 4 Ohms
¡¤ Class AB input stage plus premium Class D power stage
¡¤ Independent audio sensing triggers, one for each zone
¡¤ 6 Independent 12 volt trigger inputs, one for each zone
¡¤ Looping 12 volt trigger outputs for each zone
¡¤ Master 12 volt trigger input to turn all zones on-off
¡¤ Speaker level input for expanding systems w/out pre out jacks
¡¤ Two bus inputs can be routed to any zone
¡¤ Bus loop output jacks for passing audio to another amp
¡¤ Mono mode combines L and R for single speaker applications
¡¤ Separate level controls for all twelve channels
¡¤ Detachable speaker connectors accept up to 12 gauge wire
¡¤ Short circuit and overheat protection with front panel indicators
