功放输入级器件工作时噪音的大小,直接影响放音质量。器件噪声产生、大小与工作温度有关。温度愈低,噪音愈小,反之亦然。用低温降噪器对器件进行冷却降噪,即简单,效果又好。低温降噪器外形见图。 它由弧状梳形散热器、半导体致冷器、蓄冷板通过结构件连接而成。使用时,把器件紧贴在冷却穴内的蓄冷板上,接通电源,致冷器工作产出的冷量由蓄冷板贮存,并迅速传给器件,使其工作在+5℃～15℃之间,噪音大大降低,放音质量提高。为提高致冷效率,致冷器采用进口件,它的温差系
Power amplifier input stage noise when the size of the work, a direct impact on playback quality. Device noise generated, the size of the working temperature. The lower the temperature, the smaller the noise, and vice versa. The use of low-temperature noise reduction device cooling noise reduction, that is simple, good results. Cryogenic noise reducer appearance shown. It consists of arc comb-shaped radiator, semiconductor cooler, cold plate through the structural connection. Use, the device close to the cold storage hole in the cold plate, turn on the power, the output of the cold work cold storage from the cold plate, and quickly passed to the device to work in the +5 ℃ ~ 15 ℃ Between, greatly reduce noise, improve playback quality. In order to improve the refrigeration efficiency, the refrigerator uses imported parts, its temperature difference
