Push down on the spring terminals at the back of the speaker, and insert

the wires. Release the springs to secure.

Figure 7 — Insert audio wires into the terminals

NIf the ends of the wires are damaged and need to be restripped, follow the instructions in the SI 26 and SI 28 User's Guide.

2.	Turn on the audio source and any associated devices.
	Adjust the source and device settings as desired to get the
	optimum audio output for your speaker application.
3.	To adjust the speaker angle insert the allen hex tool into
	the locking access, loosen the hex cap screw, and adjust to
	the desired angle (see figure 8). Torque the hex cap screw
	down clockwise until snug, about 6 to 8 turns, for the
	speaker to sit securely in the desired position.

Turn clockwise to tighten.

NAfter locking it into place, check that the speaker is secure and cannot be lifted from the wall mount assembly. If it does lift out, continue tightening down the hex cap screw until it is no longer possible to lift the speaker from the assembly.

4.	Replace the Extron logo, pressing it firmly into place.
