| 174085 | 2003-09-10 04:22:00 | Damn. Doesn't surprise me. I guess the microphone is mono and line in is stereo and that is why there are always two. I always thought it was something to do with one needing amplification and the other being amplified at source. robo. |

| 174086 | 2003-09-10 04:32:00 | But they tell you it's a microphone input. They use a stereo jack for it, of course, to provide bias for electrets. Anyway stereo is only a modern thing ... Blumlein got the patents about 1930. B-) I've just had a look at my several year old Winbook laptop: it's got a MIC jack. Marked as that. :D Each hole in the case, and each jack costs a few cents. They try to make them cheaply. |

| 174087 | 2003-09-10 05:38:00 | The only thing I'm annoyed about is that the specs say "Microphone / Line-in". They should really just call it a Microphone socket and drop the Line-in part. Or state that Line-in will only be Mono! | CYaBro (73) | ||
| 174088 | 2003-09-10 11:32:00 | I can understand your frustration CYaBro. Frequently the specs for these connections are vague or non existant. It seems unlikely that one socket could serve satisfactorily as both a line in & mic input. Apart from a vast difference in signal levels, the soundcard mic input is usually very different from the line in. The mic is only a monaural input, on the tip of the 3.5mm plug providing preamplification for the low mic output level.. The ring of the same plug provides a small DC voltage for powering the typical PC electrec microphone used for computers. The L & R stereo line in/out signals, connect to the 3.5mm plug/sockets on the tip & ring, at 'line levels' which are much greater than mic levels. Well thats what I have learned about the SB Live card connections I use. Maybe some are different, but to expect you to use one socket for both linein/mic seems unsatisfactory without adequate specifications. |

| 174089 | 2003-09-11 00:01:00 | Cheers for that Bazza. So there is actually a small amount of electricity going out of the microphone socket. That'll explain why when I have it plugged into my amp it cuts out the left channel on the tape deck VU meter but the sound is still there. | CYaBro (73) | ||
