8.	When the assembly is securely in place, loosen the hex
	cap screw (turn counter-clockwise) and rotate the front
	section back into a vertical position with the hex cap screw
	at the top. Using the allen hex tool, turn the hex cap screw
	clockwise to tighten.

9.Remove the cover from the back of a speaker and carefully slide the speaker box bracket down into the V lock groove until it locks into place (see figure 7).

Slide the speaker onto the wall mount assembly.

NExtron recommends that the wiring installation is 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 5). Secure the wire at various places to the stud, 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 6) to allow ease of connection to the speaker
	after installation.
	Pass the wires
	through the plate
	access hole.

7.Place the wall mount assembly against the wall, aligning the plate holes with those drilled, and secure with appropriate hardware.

10.To adjust the angle of the speaker, carefully remove the Extron logo on the front of the speaker to expose the front locking access (see Figure 1, Item 3, for location). Insert the allen hex tool into the locking access, and slightly loosen the hex cap screw. Adjust the speaker to the desired angle (see figure 8), and torque the cap screw down clockwise until snug. The speaker will sit securely in the desired position. Install the Extron logo.

NThe Extron logo can be fitted either horizontally or vertically.

Turn clockwise to tighten.
