• Zone 1 (channel 1&2) are higher power for more demanding applications
• 24 speaker connections (A and B outputs for all 12 channels)
• High current for stable operation at 2 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
• Summed Mono mode combines L and R for single speaker applications
• Separate level controls for all twelve channels
