How to stop static or white noise from Universal Audio apollo x16 when nothing is plugged in?
If you hear static or white noise when nothing is plugged in, mute or lower the preamp gain to the minimum on all unused preamp channels, as mic preamps can emit noise even without a connected device. Also, some UAD plug-ins model the noise characteristics of the original equipment; you can defeat the noise model in the UAD plug-in GUI or mute the channel containing the plug-in to temporarily eliminate the noise.
Why can't I hear my Hi-Z input(s) on Universal Audio apollo x16 Accessories?
