Split Sum
This mode is best suited to people who run a mono pedal board,
but like using two amps. To change to this mode take the lid off the
box and move the two dip switches from Stereo Sum to Split Sum.
Connect your last pedal to the left (L) return of The Underfacer
and keep it in blue mode. This will create a dual mono signal. If you
switch to red mode the L output will stay active, but the right (R)
output will have no signal.
Ground Lift & Phase Correction
(The TX Underfacer only)
The TX Underfacer features red and black push buttons.
Press the red button to lift ground of the R output. Press the black
button to invert the phase of the R output by 180°
For phase inversion to work ground lift must be active – red button
pushed in.
Note. For ground lift to be effective, the outputs of The Underfacer
need to be connected directly to your amps. If you want to install
it under an angled board that has side panel connections, make
sure the ground of whatever side panel connectors you’re using are
not the same. To achieve this the jacks should either have a plastic
housing or be mounted into plastic or wood to make sure they do
not share a common ground.
