By taking a proven but underutilized Pro Audio amplifier class and bringing it up to date with modern components we can achieve uncompromising sound quality in a compact chassis that makes installation in even the most challenging cars and trucks a breeze.\u003cbr\u003e\u003cbr\u003eSwitching to a higher class. Class G and Class G\/H amplifiers offer the best of all possible characteristics. Power output, distortion, efficiency, heat, noise, size are all class-leading specs with this design.\u003cbr\u003e\u003cbr\u003eWhy does this class of amplifiers perform so well? It's built for music, not test tones or noise. Class G\/H works with the dynamics of your music, not against them. When an amplifier is playing music, even at full volume, due to its dynamic nature, it is really only working above 1\/2 power about 10% of the time. You only need full power during the very loud passages like the impact of a drum or the pluck of a bass string. The rest of the time your 700-watt amp is making less than 350 watts. That's where the KS amp's Class G\/H design comes into play. It's like having 2 amps in one. A 400-watt amp is much smaller and produces a lot less heat. Then, in a fraction of a second, your becomes an 800-watt monster that is ready for any musical challenge. The trick to making this work is in striking a balance between switching the high-power section on and off. It takes the years of experience Nikola Engineering has to achieve this delicate balance. \u003cbr\u003e\u003cbr\u003e4 - Channels @ 4 Ohms 75 Watts\u003cbr\u003e4 - Channels @ 2 Ohms 125 Watts\u003cbr\u003e2 - Channel @ 4 Ohms (Bridged) 250 Watts\u003cbr\u003eFrequency Response 20Hz - 20kHz\u003cbr\u003eCrossover Range 40Hz - 550Hz\u003cbr\u003eBass Boost +15dB @ 45Hz\u003cbr\u003eS\/N Ratio 109dB\u003cbr\u003eInput Sensitivity (Low) 220mV - 3.5V\u003cbr\u003eMax Current Draw 51A @ 500 Watts 1% THD\u003cbr\u003eIdle Current 1.14A\u003cbr\u003eFuse 2 x 30 Amp\u003cbr\u003eDimensions 11.625\"(L) x 5.125\"(W) x 1.75\"(H)\u003cbr\u003e \u003cbr\u003eCompact Chassis Design For Small Vehicle Applications.\u003cbr\u003eNon-Digital Class G\/H Switching Design.\u003cbr\u003eDesigned By Robert Zeff.\u003cbr\u003eProtection Against: Reverse Voltage, Over Voltage, Speaker Short, and Thermal Overload.\u003cbr\u003eCan Drive Highly Reactive Loads.\u003cbr\u003eHi\/Low Level balanced Switchblade RCA Inputs For Flexible Integration Into Most Applications.\u003cbr\u003eOptically Isolated Mosfet Power Supply.\u003cbr\u003eStable To 2-Ohms.\u003cbr\u003eThe KS 125.4 Mini Uses a Patent Pending Auto-Sense Turn-On Circuit That Offers a Significant Improvement in Reliability and Operation.\u003cbr\u003eTo Further Simplify OEM Integration The KS 125.4 Mini Uses A Fully Balanced Input Stage That is Switchable Between Speaker And RCA Inputs.
