In this case use Bypass.

Case 10 Editor has more bits than final carrier

In this case use Emphasis (if the recording is not already pre- emphasised) and if there is sufficient headroom at high frequencies, or:

use Gain on the maximum setting which does not cause clipping.

In both cases, also select:

Shape A, B, C or D.
