首先来说,因为国内市电标称是220V,如果需要使用110V电压输入的设备,需要在电源后接一个220V转110V变压器,再把音箱电源插口接入变压器的插座,谈到这个外置的变压器,就涉及以下几个问题:一目前市面上220V转110V的变压器,很多的标称功率在实际使用上根本达不到,尤其是面对电子管类音箱这种大功耗用电器时,功率不足会造成很多种问题的出现,最常见的就是通常说的:“带不动”。(标称100W的电子管音箱,这个100W不是指它的功耗,这个只是指音箱的放大功率。) First of all, because the domestic electricity is nominally 220V, if you need to use 110V voltage input device, you need to connect a 220V to 110V transformer, then the speaker power outlet into the transformer socket, the external Transformer, it involves the following questions: A currently on the market 220V to 110V transformer, a lot of nominal power simply can not reach the actual use, especially in the face of electronic tube speakers such large power consumption appliances, power Insufficient will cause a variety of problems, the most common is usually said: “no movement ”. (Nominal 100W tube loudspeaker, this 100W does not refer to its power consumption, this only refers to the amplifier’s amplification power.)
