EZ Norm Series
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 positions,
if needed.
