Mounting the Unit in a Rack 

DM 15GE-2 equalizers can be mounted in any standard 19” rack. The 30GE-2 requires 3 
rack spaces while the 30GE-1 requires only 2. To make mounting easier, lay the rack on its 
back with the equipment front panels facing up. Remove any rack screws from the part of 

the rack where you are planning to mount the equalizer. Position the TDM 15GE-2 equalizer in 
the rack as desired. Make sure the mounting holes in the equalizer line up with the screw holes in 
the rack rails. Use four standard 10-32 rack screws for each equalizer. We recommend that the 
rack screws have plastic washers to prevent damage to the paint on the face of the equalizer. 
Install each screw loosely through a mounting hole in the equalizer and into the rack. Do not 
tighten the screws until they are all in place. After all four screws are installed loosely, make sure 
the equalizer is placed exactly as you desire and then tighten the four screws until they are nice 
and snug, but not overly tight.
