When you're digitising audio you can just connect the tape/LP output to a |
15 |
line in input. AFAICT the "tee" is only needed for capturing digital output |
16 |
that's coming from the PC itself. |

Also, for LPs, if you don't run the LP output into an amplifier phono |
19 |
input, it will miss out on the EQ reversal that occurs there. The physical |
20 |
characteristics of vinyl media mean that some frequencies are harder to |
21 |
encode in a vinyl groove than others (cant remember if its high or low |
22 |
freqs) so as part of the manufacturing process they put the signal through |
23 |
a filter before its written to vinyl, then the phono input on the amp |
24 |
reverses that filter to restore the signal. I'd imagine you could use a |
25 |
digital EQ to restore the signal if you don't have an amp with phono input |
26 |
handy. |
