Lines: 23 I have a three-head tape deck with a bias-fine-tune control. Before recording a tape, I tune my receiver to a spot on the FM dial where there are no stations (just a lot of hiss) and then I use the monitor switch on the tape deck to switch between 'TAPE' and 'SOURCE' while recording the hiss. This al- lows me to compare the hiss a split-second before it is recorded with the sound after it has been recorded. I turn the fine-bias-adjustment control until the sound is the same when switching between 'TAPE' and 'SOURCE'. My question is, should this procedure be done with Dolby off, or on? (I use Dolby C) It seems to make quite a bit of difference. Does anyone know which way is correct? Can anyone suggest a more precise method of adjusting the bias with- out using lots of expensive equipment? Having a technician do this for one brand of tape won't work since I use many different brands of tape. Thanks, Dennis -- Call-Me: Dennis Gibbs, Univ. of Md. Comp. Sci. Center.
