QSC CXD4.2 เครื่องขยายเสียง 4 channels, 400 watts/ch at 8Ω, 400 watts/ch at 4Ω, 325 watts/ch at 2Ω
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.
• 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
