Crest Audio CKi 1600v Professional Installation Amplifier

With their proven track record, CKi amplifiers are designed for the most demanding contractor applications. With the ability to deliver audio, via CobraNet, and control on one CAT5 cable, the CKi series enables contractors and system designers to perform functions that other amplifier manufacturers simply cannot. By using Ethernet technology directly to the amplifier, the CKi series becomes an ultra scaleable system capable of economically powering anything from the smallest building to the largest theme park or stadium. FeaturesLegendary overbuilt power supply Rear-mounted attenuators with removable knobsEuro-style connection block, input and outputFront panel labeling areaSignal present, active, protect and ACL. LEDs (on front and rear of amplifier)PowerSave and sequential turn off (hardwired STO standard on all models)Fault I/O for connection to other monitoring systemsOptional input isolation transformers availableFive-year warrantyPowerSaveAll CKi amplifiers come standard with PowerSave circuitry.This effectively reduces currentdraw and thermal emissions to a minimum when the amplifier is at idle. PowerSave operates by cutting off the bias current to the output stage after absence of signal is sensed at the input.When signal presents itself, PowerSave instantly restores the bias current after the first positive-going waveform. Current draw specifications while PowerSave is active are included in specifications under "Idle Current Draw."
