tape monitor switch
I just connected a headphone amp to the tape out (1) on my Mac c-712 pre-amp. I notice that I get signal whether or not the tape monitor button is set to "on." I can actually play a tape through tape out (2) at the same time as listening to the cd through the headphone amp. I don't get it. Thanks for your help.
