Feature. 
Flexible Amplifier Summing Technology™ (FAST) drives most any loudspeaker system or configuration by distributing total amplifier power across one, two, three or all four channels. 
• Includes 70V and 100V direct drive. 
• Full function onboard loudspeaker processing DSP with Crossover and Parametric EQ Filters, Limiting and Alignment Delay eliminate the need for outboard loudspeaker processors. 
• PowerLight universal switchmode power supply with PFC for highest effiency, improved audio performance, and low heat dissipation. 
• Preset Wizard simplifies amplifier setup providing system design tools and loudspeaker selection from a list of speakers. 
• Powerful Intrinsic Correction™ processing maximizes the sonic performance of QSC loudspeakers. 
• 20 Factory Preset configurations that can be modified and stored in the 50 User Presets. 
• Integrated front panel with channel Select and Mute buttons, Input and Output LED Metering, 400x240 LCD, intuitive navigation buttons, LED power button and indicator, and cast aluminum handles. 
• GPIO for additional functionality including a heartbeat output for Life-Safety supervision. 
• Four Input Phoenix connectors, and four Phoenix touch-proof Speaker
