NExtron recommends that the wiring installation be performed by a professional audio equipment installer.

5.

Using compatible speaker wire (Extron recommends using

 

12-18 AWG), route the wire from the audio source to the SI

 

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 to align with the plate (see

 

figure 7). Secure the wire to the stud at various places, but

 

allow enough freedom of movement near to the hole for

 

connection to the speaker.

6.

Pull sufficient wire up through the holes in the rear plate

 

(see figure 8) to allow ease of connection to the speaker

 

after installation.

NDo not strip and connect the wire at this time.

Pass the wires through the plate access hole.
