I have an Apple Mac-book pro which has only one 1/8' output jack Headphones/Mic. I have a number of various configurations of RCA jacks even with 1/8" Pin. I have a turntable and cassette player. What I am needing help with is the Method I need to use, in order to capture the sound into digital. I expect to have to clean the sound somewhat, but would like to preserve some of this old Music for the use of others as well as myself. All help and suggestions will be gratefully received. Thanks Cebustu.
