我在用的两个耳放,viva stx静电放,还有niimbus us4+动圈平板放都是有复数个耳机孔。每个耳机孔相位不一样。
上图是US4+的原理图,可以看出来,耳放有一个四芯平衡口和两个6.3单端口。6.3的耳机孔呢,右边的相位是正确的,左边的相位是反的(对应的平衡口的L-和R-)。说明书上也文字说明了,右边的相位是正的,左边的相位是反的。
理论上来说的话,我动圈耳机接反相的耳机孔,声音会和正相位的有什么区别吗?
实际上呢,我ab两个单端口,我觉得我耳朵是聋的,听不出区别来。
另一个耳放是viva stx,我贴一下说明书上关于相位的描述。
The two connectors have the characteristic of being in opposite "absolute" polarity, one to eachother, this to fullfill the use of different headphones with "Polarity” ("phase") connecteddifferently. This because from measurements from our factory and from the "audiophile'community came the information that some models of "Electrostatic Headohones" are cabledwith different so named "absolute phase' or "absolute polarity", Connect the owned headphonesto the socket that gives better musical listening performance.
in other words, this feature is implemented in order to allow the listener to choose what is thepolarity that renders best listening, since different models of Headphones can be wired withdifferent absolute polarity .
lmportant: in the case of the "D" input selected, both the two sockets would have the "AbsolutePolarity'("Absolute Phase) inverted, in comparison with the use of reqular inputs. The twoOutput Headphones Sockets, will be still with "Absolute Polarity" ("Absolute Phase”) "inverted"("opposite") one to each other.
The listening can vary with recordings, since, comes from many audio informations sources theclaim that different recordings are characterized by the "Absolute Polarity" inverted.
大意是,两个耳机孔相位是相反的,然后D输入时候耳机孔的相位和其他输入又是相反的,但是厂家也不告诉你哪个耳机孔相位是这么样的。至于哪个耳机孔声音会好,和你耳机、录音都有关系,你自己试。
这静电胆机,我不敢热插拔AB,姑且两边的耳机孔都试过了(包括D输入跳过前级),我也没办法确定有没有什么区别。
就,理论上,耳机孔相位反的话,会有什么影响吗?
