| 142961 | 2003-05-10 21:12:00 | A friend of mine wants to put his old records onto CD. The output on his record player has 2 RCA sockets, but I'm wondering, aren't records only recorded in mono? Is it actually possible to have a "stereo" record? | somebody (208) | ||
| 142962 | 2003-05-10 21:18:00 | From around 1960 most LP's (vinyl records) were issued in stereo.There was the quadraphonics era of course!!! :-) | Neil McC (178) | ||

| 142964 | 2003-05-10 21:27:00 | Sure is, um sure was, stereo records, and before that there was mono records, The needle fits into a groove, lets call it a valley, On the mono records only one hill of the valley be modulated, on a stereo record both hills are modulated. Then in a stereo cartridge if the neadle moves in a 45° direction what would pick up one channel, if it moved in a 135° direction that would pick up the other channel, |

| 142965 | 2003-05-10 21:31:00 | Thanks for the explanation E . ric . It was a $2 record player picked up from a garage sale (with broken RCA plugs - which I replaced) . It seems reasonably modern, which is good . The records my friend wants to put onto CD are along the lines of orchestral pieces, from quite a while ago . . . |

| 142966 | 2003-05-10 22:58:00 | "Quite a while ago" is only relative. In the olden days when I first started collecting jazz records, there were only 78 rpm mono records anyway, and, outside of laboratories, the word mono had no meaning. There were early attempts to play stereo by synchronising two 78 rpm records that had been mastered at the same time, but similarly and even more interestingly, there are the the very few odd early electrical recordings that were made and had used 2 microphones in different positions. Each had been connected to a recording machine and each had been mastered and issued as different takes. But since they are of the same sounds it has been possible to synchronise these and produce truly stereophonic recordings from the 1920s. Only one or two mind. |

| 142967 | 2003-05-10 23:00:00 | What age are the records? Are we talking 78rpm here? Maybe I took too much LSD, but I swear my PinkFloyd albums were in stereo.......... LOL. However some of the early 33rpms were recorded in pseudo stereo (eg two channel mono) Grab an early Beatles album, put it on the turntable - if you turn the balance to the left you will hear the music and to the right, only the vocals. However you will find most LPs from the 70's onwards are in true stereo. |

| 142969 | 2003-05-11 02:52:00 | I have heard of stereo AM, but I think the receivers are few and far between. Radio DXing is a good hobby too |
