首先应了解自己“家庭影院”(包括大屏幕彩电、VCD机、调音台或均衡器、功放机等)的话筒输入方式,您想将话筒从哪一部分输入等。如从VCD机或功放机的话筒输入插孔MIC输入,就要考虑您的VCD机或功放机对话筒的适应能力,主要是话筒的输入阻抗、频率响应、动态范围及话筒插头的大小等。有些音响(主要是有些进口音响)的话筒输入灵敏度很高,如选配600Ω及以上的中、高阻话筒,唱歌时将会产生啸叫;相反,有些音响的话筒输入灵敏度较低,如果选配200Ω的低阻
First of all should understand their own “home theater” (including large-screen TV, VCD player, mixer or equalizer, amplifier, etc.) microphone input, which part of the microphone you want to enter. Such as VCD player or amplifier microphone input jack MIC input, it is necessary to consider your VCD player or amplifier to adapt to the microphone, the microphone input impedance, frequency response, dynamic range and the size of the microphone plug. Some audio (mainly some imported audio) microphone input sensitivity is high, such as matching 600Ω and above the microphone, high impedance microphone will produce whistle; on the contrary, some microphones microphone input sensitivity is low, if the election With 200Ω low resistance
