With E/Z Vinyl Tape Converter there is one overall record level adjustment (applied to both channels) via a Gain slider (range -3 to +9) on the same screen where you select "Record", it is not that obvious and does not appear to be referenced in the documentation.

With Audacity there are record level slider adjustments for both channels which can be adjusted to get a max dB record level (to avoid signal clipping etc) as shown on the record level meter displays, once recorded then several ways to re-adjust levels with Amplify, Normalize etc edit commands under the Effect menu.
