style=\"font-size:16px;font-weight:bold\"\u003eK series digital power amplifier has very strong performance, the total output power reaches more than 10000W, and only needs the installation space of 1U rack. It is one of the most powerful and advanced power amplifier products on the market.\u003cbr\u003e\u003cbr\u003eThe efficiency is over 97%, and the calorific value is low, which means that it has stable and reliable performance and is more durable.\u003cbr\u003e\u003cbr\u003eWith extremely wide power adaptability, built-in 20000 W power regulator, it can adapt to the worst power supply environment, thoroughly solve the problem of voltage instability in remote areas.\u003cbr\u003e\u003cbr\u003eWe have carefully selected all kinds of top-level components. Each power amplifier has more than 4000 components. A large number of original imported raw materials are used, such as Fairchild, ON Semiconductor, Infineon, TDK, and STMicroelectronics. We have selected chips of HiFi Class to get unbelievable sound.\u003cbr\u003e\u003cbr\u003eThe protection circuit of each channel is independent, even if one channel can not work, it will not affect other channels, providing higher protection for each performance.\u003cbr\u003e\u003cbr\u003eEach power amplifier has passed more than 100 full range tests of AP (AudioPrecison) System to ensure that each power amplifier achieves the most ideal parameters and performance, and maintains the high consistency of products.\u003cbr\u003e\u003cbr\u003eIt is a perfect choice for places that need relatively high continuous power and high requirements. It pays attention to the timbre, and is highly efficient. At the same time, it also achieves good stability, portability and adaptability. K series power amplifier is the first choice for the first-class system designer, sound engineer and system technician to provide the most reliable and highest level power and dynamic margin in the smallest possible size.\u003c\/p\u003e\n\u003c\/div\u003e\u003cdiv class=\"detailmodule_image\"\u003e\u003cimg class=\"detail-desc-decorate-image\" src=\"https:\/\/ae01.alicdn.com\/kf\/S870eef4071b44b1dbac69d0d11c05547G.png\" slate-data-type=\"image\"\u003e\u003c\/div\u003e\u003cdiv class=\"detailmodule_text\"\u003e\n\u003cp style=\"font-size:20px;font-weight:bold\"\u003eK435 Technical Parameters\u003c\/p\u003e\n\u003cp style=\"font-family:OpenSans;font-size:14px;font-weight:300;line-height:20px;white-space:pre-wrap;color:rgb(0, 0, 0);margin-bottom:12px\" class=\"detail-desc-decorate-content\"\u003e8Ω Stereo Power: 4 x 3500W RMS\u003cbr\u003e4Ω Stereo Power: 4 x 6300W RMS\u003cbr\u003e2Ω Stereo Power: 4 x 7800W RMS\u003cbr\u003e8Ω Bridged Power: 2 x 12600W RMS\u003cbr\u003e4Ω Bridged Power: 2 x 14000W RMS\u003cbr\u003eHeight: 1U, Class D, 4-channel digital power amplifier\u003cbr\u003e(Operating voltage: 90-260V 60Hz\/50Hz)\u003cbr\u003e1U digital 4-channel power amplifier with PFC\u003cbr\u003eMaximum output voltage\/current in stereo mode: 185V\/85A peak\u003cbr\u003eMaximum output voltage\/current in bridge mode: 370V peak\u003cbr\u003eTHD (at 1kHz and 1dB below clipping): \u0026lt;0.05%\u003cbr\u003eFrequency response (20Hz-20kHz): 20Hz-20kHz +0\/-1dB\u003cbr\u003eGain (selectable) 8 ohms: 32dB\/35dB\/38dB\/41dB\u003cbr\u003eOperating Temperature: 0°C-45°C\/32°F-113°F\u003cbr\u003eOutput Jack: Neutrik Swiss Speakon Connector\u003cbr\u003eInput Jack: Combo XLR Type 3-pin\u003cbr\u003eTHD + N Harmonic Distortion: \u0026lt;0.5% (typical \u0026lt;0.05%) from 1 W to full power\u003cbr\u003eIMD (Intermodulation Distortion): \u0026lt;0.5% (typical \u0026lt;0.05%) from 1 W to full power\u003cbr\u003eSignal-to-Noise Ratio: \u0026gt;110 dB\u003cbr\u003eSensitivity (rated power into 8 Ω): 0.775 V\/1 V\/32 dB\u003cbr\u003eDamping Factor: \u0026gt;5000 @ 20-200 Hz\u003cbr\u003eSlew Rate: \u0026gt;50 V\/µs @ 8 ohms\u003cbr\u003eInput Impedance, Balanced \u0026gt; 20 kΩ \/ Unbalanced \u0026gt; 10 kΩ\u003cbr\u003eResolution: ≥ 75 dB\u003cbr\u003eCrosstalk: \u0026gt;66 dB @ 1 kHz\u003cbr\u003eSignal-to-Noise Ratio (SNR) \u0026gt;110 dBA (20 Hz-20 kHz, weighted)\u003cbr\u003eLED Indicator: Temperature Display: Green indicates normal operation, Yellow indicates overheating warning\u003cbr\u003eCooling: Temperature-controlled variable-speed air cooling system, front-to-back cooling\u003cbr\u003eProtection: Soft start, VHF, AC\/DC protection; limiter; over-frequency; short circuit; long-term amplifier; thermal; temperature warning; switch mute; signal line hot-swap and overload protection.\u003cbr\u003ePower supply voltage: PFC universal power supply system with 90-260V voltage selectable.\u003cbr\u003eSuitable for voltages in any country; 50Hz-60Hz.\u003cbr\u003eDimensions (W * D * H): 482*460*44mm.
