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.\u003c\/div\u003e \u003cdiv\u003e \u003c\/div\u003e \u003cdiv\u003e\u003cspan style=\"font-weight: bold; text-decoration: underline;\"\u003eFeatures\u003c\/span\u003e\u003c\/div\u003e \u003cdiv\u003e \u003cul\u003e \u003cli\u003eLegendary overbuilt power supply \u003c\/li\u003e \u003cli\u003eRear-mounted attenuators with removable knobs\u003c\/li\u003e \u003cli\u003eEuro-style connection block, input and output\u003c\/li\u003e \u003cli\u003eFront panel labeling area\u003c\/li\u003e \u003cli\u003eSignal present, active, protect and ACL.

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\/div\u003e \u003cdiv\u003e \u003c\/div\u003e \u003cdiv\u003e \u003cdiv\u003e\u003cspan style=\"font-weight: bold; text-decoration: underline;\"\u003eSpecification\u003c\/span\u003e\u003c\/div\u003e \u003cdiv\u003e \u003cul\u003e \u003cli\u003eRated power bridge mode 4 Ohms: 1,600 Watts @ 1 kHz at \u0026lt;0.1% T.H.D.\u003c\/li\u003e \u003cli\u003eRated power bridge mode 8 Ohms: 800 Watts @ 1 kHz at \u0026lt;0.1% T.H.D.\u003c\/li\u003e \u003cli\u003eRated power (2 x 2 Ohms): 800 Watts per channel @ 1 kHz at \u0026lt;0.05% T.H.D. both channels driven\u003c\/li\u003e \u003cli\u003eRated power (2 x 4 Ohms): 600 Watts per channel @ 1 kHz at \u0026lt;0.05% T.H.D. both channels driven \u003c\/li\u003e \u003cli\u003eRated power (2 x 8 Ohms): 400 Watts per channel @ 1 kHz at \u0026lt;0.025% T.H.D. both channels driven \u003c\/li\u003e \u003cli\u003eMinimum load impedance: 2 Ohms \u003c\/li\u003e \u003cli\u003eMaximum RMS voltage swing: 64 Volts \u003c\/li\u003e \u003cli\u003eFrequency response: 10 Hz - 20 kHz;+0,-2 dB at 1 Watt \u003c\/li\u003e \u003cli\u003ePower bandwidth: 10 Hz - 20 kHz; +0, -2 dB at rated 400 Watts 8 Ohm power \u003c\/li\u003e \u003cli\u003eT.H.D.
