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.\"\u003c\/p\u003e \u003cp\u003eSpecifications\u003c\/p\u003e \u003cul\u003e \u003cli\u003e\u003cspan style=\"font-size: 10px;\"\u003eOutput Power, 70.7V: 1200 Watts\u003c\/span\u003e\u003c\/li\u003e \u003cli\u003e\u003cspan style=\"font-size: 10px;\"\u003eMax RMS Output Voltage (each channel): 92 Volts\u003c\/span\u003e\u003c\/li\u003e \u003cli\u003e\u003cspan style=\"font-size: 10px;\"\u003ePeak Output Voltage (each channel): 130 Volts\u003c\/span\u003e\u003c\/li\u003e \u003cli\u003e\u003cspan style=\"font-size: 10px;\"\u003eFrequency Response (+0 \/ -0.3dB, 1W\/70.7V): 10Hz-20kHz, -3dB @148kHz\u003c\/span\u003e\u003c\/li\u003e \u003cli\u003e\u003cspan style=\"font-size: 10px;\"\u003ePower Bandwidth (full power, 1% THD+N): 10Hz - 20kHz, +0\/-0.2 dB\u003c\/span\u003e\u003c\/li\u003e \u003cli\u003e\u003cspan style=\"font-size: 10px;\"\u003eTourClass® Protection ACL, IGM, Auto\u003c\/span\u003e\u003c\/li\u003e \u003cli\u003e\u003cspan style=\"font-size: 10px;\"\u003eRamp, short circuit, DC voltage, turnon\/off transient, current inrush, sub\/ultrasonic input\u003c\/span\u003e\u003c\/li\u003e \u003cli\u003e\u003cspan style=\"font-size: 10px;\"\u003e.THD+N (rated power, 1kHz): \u0026lt;0.1% @ 70.7V out\u003c\/span\u003e\u003c\/li\u003e \u003cli\u003e\u003cspan style=\"font-size: 10px;\"\u003eSMPTE IMD (rated power, 60Hz \u0026amp; 7kHz): \u0026lt;0.1% @ 70.7V out\u003c\/span\u003e\u003c\/li\u003e \u003cli\u003e\u003cspan style=\"font-size: 10px;\"\u003eInput CMRR (1kHz): \u0026gt;60 dBInput Sensitivity (rated power): 1.77V @ 70.7V out\u003c\/span\u003e\u003c\/li\u003e \u003cli\u003e\u003cspan style=\"font-size: 10px;\"\u003eStandard Voltage Gain X40 (jumper-selectable for X20 or .775V sens.)\u003c\/span\u003e\u003c\/li\u003e \u003cli\u003e\u003cspan style=\"font-size: 10px;\"\u003eInput Impedance (balanced\/unbalanced) \u0026gt;20k Ohms \/ \u0026gt;10k OhmsHum and Noise (\"A\" weighted, rated power): -105 dB\u003c\/span\u003e\u003c\/li\u003e \u003cli\u003e\u003cspan style=\"font-size: 10px;\"\u003eCrosstalk (\"A\" weighted, rated power): \u0026gt;-60dBClass: HInput Connectors (per channel): Rear-panel barrier strip input, 4-pin Phoenix sequential turn-on\/off connector on standard CC-STL module\u003c\/span\u003e\u003c\/li\u003e \u003cli\u003e\u003cspan style=\"font-size: 10px;\"\u003eOutput Connectors (per channel): Rear-panel barrier strip output\u003c\/span\u003e\u003c\/li\u003e \u003cli\u003e\u003cspan style=\"font-size: 10px;\"\u003eFilter Storage: 37,000 μF\u003c\/span\u003e\u003c\/li\u003e \u003cli\u003e\u003cspan style=\"font-size: 10px;\"\u003ePower Supply (factory configured): 100V-240V, 50-60Hz\u003c\/span\u003e\u003c\/li\u003e \u003cli\u003e\u003cspan style=\"font-size: 10px;\"\u003eIdle Current Draw 120V: 1.3 A (PowerSave active)\u003c\/span\u003e\u003c\/li\u003e \u003cli\u003e\u003cspan style=\"font-size: 10px;\"\u003e1\/8 Power Curr.
