The EZ Norm offers a simplified method for setting up and changing
normals to a Bantam/TT patchbay. Simply remove the middle
designation strip, and rotate the center cam, using a standard
screwdriver. An audible “click” can be heard as you rotate from
full normals to no normals to half normals. An opaque marking
strip is included to conceal the normal position, if needed.
