ZoneMaster 450

 Features 

·         Our ZoneMaster models are very similar in their feature sets, differing mainly in size and number of channels.

Looking for more channels? Try the 1250 or 650. Fewer? 250.

·         Universal amplifier for applications from 50 to 200 watts

·         4 speaker connections (not enough room for additional Phoenix connectors on ZM450 rear panel)

·         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

·         2 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

·         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 four channels

·         Detachable speaker connectors accept up to 12 gauge wire

·         Short circuit and overheat protection with front panel indicators

·         0.9 watt standby power consumption meets Energy Star & EU specs
