This ensures that not only the position of all sound sources is correct but also their volume. With HPm, this parameter, which we call “Center” in the Phonitor Matrix, can also be adjusted in three settings. You can choose between an attenuation of -0.5dB, -1 dB or -1.5 dB. The standard for an authentic representation of the stereo image is -1 dB. During conventional listening on headphones, our brain can compensate a certain level of false playback representation – but this is very exhausting and leads to listening fatigue.\u003c\/p\u003e\n\u003ch3\u003eSPL HPm Specifications\u003c\/h3\u003e\n\u003cdiv class=\"row\"\u003e\n\u003cdiv class=\"technical-description\"\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum input \u0026amp;
