Essentially, since most Mixxx users don't have high-end hardware and/or want to test out VC before buying additional gear. But we've never tested or heard reports of others trying it on higher-end gear, so we don't really know how well it would work in practice. At best, results will vary depending on the specific sound card and environment. (We write the documentation to help the average user get good results with minimal fuss, so usually only talk about best practices.) > indicate these can provide 118 dB gain (trim range -96 to +22 dBu) > with -102 dB THD+N.

The analog noise (coming in on the cables before the ADC) you'll get from that much linear gain (~46dB) could still interfere with the HF time code position signal. > The Mixxx manual explicitly states that microphone inputs won't work > for timecode.
