The CDi Series of Crown amplifiers areprofessional tools designed and built forinstalled sound applications. The seriesincludes four models which are identicalexcept for output power: CDi 1000, CDi 2000,CDi 4000 and CDi 6000. All are rugged andlightweight, and offer unmatched value intheir class.
CDi-Series amplifi ers feature an intuitivefront-panel LCD screen to guide installersthrough their confi gurations. CDi amplifi ersalso offer onboard DSP for loudspeakersignal processing. Other features include aswitch-mode universal power supply, usefulfunction indicators, proportional-speed fanassistedcooling, removable Phoenix-styleinputs, barrier strip outputs for low-Z or70V/100V/140V loads, short-circuit protectionand more.
Your investment in a CDi-Series amplifi er isbacked by Crowns Three-Year, No-Fault, FullyTransferable Warranty.
