Extron electronic SI 3 manual Installing the wall mount assembly

4.Mark the wall where the wire will pass through the plate, and cut a small access hole large enough for the wire to pass through without interference. Where the stud is wider than the plate's access hole, cut the hole in the wall to the left or right and directly alongside the stud (see figure 7).

NBefore cutting the hole in the wall, make sure the plate will hide the hole after installation.

5. Using compatible speaker wire (Extron recommends using 12-18 AWG), route the wire from the audio source to the speaker location by the most convenient and safe route. If the wiring is to remain hidden behind the wall, follow the stud to where the small access hole has been cut, and feed about two feet of wire out through the hole into the room. If necessary, bend the wire behind the plate to align with the hole in the plate (see figure 7). If possible, secure the wire to the stud at various places. Allow enough freedom of movement at the hole for speaker connection.
