Mounting the Unit in a Rack

TDM 24CX series crossovers can be mounted in any standard 19” rack. Each TDM 24CX series crossover takes up one rack space. 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 crossover. Position the TDM 24CX series crossover in the rack as desired. Make sure the mounting holes in the crossover line up with the screw holes in the rack rails. Use four standard 10-32 rack screws for each crossover. We recommend that the rack screws have plastic washers to prevent damage to the paint on the face of the crossover. Install each screw loosely through a mounting hole in the crossover 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 crossover is placed exactly as you desire and then tighten the four screws until they are nice

and snug, but not overly tight.

Using the Security Cover

The security cover is used to prevent unwanted tweaking of the crossover settings. If your crossover will be installed permanently for one particular purpose, and will be set up once to operate properly, use the security cover.

If you want to use the security cover on a 24CX-2 or a 24CX-4, make sure all of your settings are correct, then install the cover. There are two holes in the face plate of the crossover—one on either end. Position the cover so that its two screws line up with the two holes. Then, using an Allen wrench, tighten the screws so that they are snug, but not overly tight.

The procedure is slightly different for the 24CX-3. This unit has buttons that protrude from its face. To use the security cover, the buttons must be removed. You can do this by simply pulling them off. They can be replaced at any time by pushing them back on. After the buttons have been removed, unscrew the two Allen-head screws from the two ends of the face of the crossover using an Allen wrench. Position the security cover over the face of the unit, insert the screws through the holes in the security cover and into the holes in the face of the unit, and then tighten the screws with an Allen wrench so they are snug, but not overly tight.
