There are a lot of "it depends" caveats regarding any quality changes. You definitely cannot do that for condenser microphones which need phantom power, and you lose the noise rejection features of a balanced interface when you change to the unbalanced interface. For a short microphone cable the noise rejection features should not make a noticeable difference. One thing which can make a difference with ribbon and dynamic mics is the input impedance of the amplifier. This may not be the place to delve into the specifics of the circuit theory and math, but the summary is that if the microphone is designed with the expectation of a typical microphone input impedance in the 1200 to 2000 Ohms range, the frequency response may be different, likely with a peak in the frequency response, when used into an instrument input with a typical 500,000 Ohm input impedance. I love this stuff, I would pull out some connectors and make adapters with matching resistors, but spending time on that kind of stuff is one of the reasons why I do not have good instrument skills, so learning circuit theory and soldering skills is probably not the way you want to spend your winter holidays. :) tl;dr version: try your normal microphone cable and just turn up the gain knob, you'll probably be fine. If it seems not enough gain, try your adapter cable and see how it sounds if you can do that in 15 minutes time and not waste a lot of your day messing with equipment instead of playing your sax. If you can get your mixer connected in less time than messing about with adapter cables and listening tests, just do that, you know it will work. -- Chris Caudle _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx https://lists.linuxaudio.org/listinfo/linux-audio-user
