i have a dmp3 preamp and a at2020 xlr mic. i have been using a 192 m-audio interface to connect the dmp3 preamp with its 1/4 output directly into my computer that way. as of late my 192 interface has been crackling and popping a lot both through my monitor speakers and recording with my microphone. i ended up connecting my monitor speakers directly into my mother board's sound card and was about to sell my whole mic setup the preamp, 192 interface, and mic. Then I realized I could easily get a 1/4 to 3.5mm cable and connect my preamp into my mother board's mic jack. This has shocked me I never thought about doing this before or that it was actually possible but now it seems to make perfect sense and makes me realize i never needed the 192 interface to begin with. i just ordered the cable to do this. it seems too easy. am i missing something? why do they have usb preamp/interfaces??? dont those have latency issues? why not just do what im doin and use the mic jack wouldnt that rid the mic of latency issues??? all computers have sound cards on their mother boards. why don't more people do this or do people do this already and im just stupid???
