Hello zdenek, yes I have a test vinyl record. And it is clear that you can hear a stereo signal on both phase and anti-phase, and you can also hear the left and right channels. That's because you have a stereo cartridge mounted on your record player. Mount a mono cartridge once and you will immediately notice the difference.zdenek wrote: ↑Tue Oct 24, 2023 10:03 amHello, Do you have a test vinyl record? I have such a vinyl record, the left channel and the right channel are recorded separately, then two channels are simultaneously in phase and anti-phase, and you can hear the difference between the left and right channels precisely, and, for example, the signal from the right channel slightly penetrates the left channel and vice versa. Recording a stereo signal in one groove is not a simple process, more is needed than the appropriate polarization of the drive coils. If anyone knows this topic, please speak up on this matter, I will be happy to learn more, best regards
Cutting a stereo signal into a groove is of course not an easy thing to do. But it has basically nothing to do with the polarization of the driver coils. The polarization is only a subsequent step to facilitate the cutting into the blank for the cutting stylus and thus to get a better signal (and to make it audible for mono pickups as well).
