Vocal recording is cutting out if too low

I am new to Cubase and have everything working except recording vocals. It seems that my vocals are recording fine, but when Cubase is playing back (or exporting) the tracks are cutting if the volume is below a certain threshold. Is there a setting I’m missing somewhere here?

Sounds like you might have a noise gate active on the channel…Check if the gate is turned on in the channel strip…or if any plugs you are using on this channel have built in gate.
