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 capability.

• 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
