Installing the SI 3 Speakers

The Extron SI 3 speakers can be mounted on a surface, such as a wall or post, or mounted in a bookcase, or on a shelf, and can be used with any Extron product supporting audio.
N If the speakers are to be placed on a horizontal surface such
as a desk or shelf, attach the back cover to enhance the speaker appearance.
Figure 4 — Surface speaker application

Desktop or bookshelf applications

1. For quick installation on a desktop or bookshelf, simply place on a desk, shelf, or other flat surface as desired.
2. Route the speaker wire (Extron recommends using 12-18 AWG) to the speakers.
3. Strip the wire and connect the speakers as described in "Wiring the speakers" on page 8.

Wall mounting applications

Installing the wall mount assembly
N Before starting installation, ensure that the wall and
wall material are capable of supporting the combined weight of the speakers and the wall mount assemblies.
1. If mounting to drywall, use a stud locator to locate the studs in the wall. Mark their position.
2. Remove the wall mount assembly from the box and loosen the central hex cap screw (turning it counter clockwise) with the supplied hex tool. Rotate the front section approximately 90 degrees to the rear mounting plate, as shown in figure 5, and tighten the hex cap screw to lock the front section in position. This makes the next steps easier to perform.
Figure 5 — Rotating and mounting the wall mount
assembly
3. Mark the location of the wall mount plate's primary mounting holes on the stud line, and drill pilot holes.
N For some surfaces the four alternative pilot dimples
(see figure 6) may be used to secure the assembly in place. Mark and drill as appropriate.

Approximate Stud Line Behind Wall
Bend wire to line up with access hole in the plate.
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).
N Before 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.
Figure 7 — Installing the wall mount assembly
N Extron recommends that the wiring installation be
performed by a professional audio equipment installer.

N Do not strip and connect the wire at this time.
Figure 8 — Passing the wire through the plate
7. Place the wall mount assembly against the wall, aligning the plate mounting holes with those drilled, and secure the assembly with appropriate hardware (see figure 5) using a screwdriver with an appropriate screw bit.
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 hex tool, turn the hex cap screw clockwise to tighten it.
9. Repeat steps 1 through 8 for the second assembly mount.

Preparing the speaker for mounting
1. If the back covers were installed previously, remove them by carefully inserting a flat bladed screwdriver to loosen the two lower locking tabs first, then one or more of the top tabs. Take care not to crack or chip the cover or break off the locking tabs. Lift away the cover as it comes free.
2. At this point connect an optional seismic safety cable (not supplied) to the rear of the speaker by looping it through the hole on the box bracket and securing it (see figure 9). Anchor the other end to a suitable secure point above the speaker wall assembly mount.
C The safety cable should be of sufficient strength
to support the full weight of the speaker and wall mount assembly combined.
N Ensure that the cable is long enough to allow you to
connect the speaker wires and to manipulate the speaker into position on the assembly mount.

Wiring the speakers

1. When both speakers are in place, carefully pull enough speaker wire to reach to the terminals at the back of the each speaker and strip the ends of the wire approximately 5/8" (15 mm). Twist the bare strands so that they are held firmly in the connectors.
2. Press down on the spring loaded terminals to open the holes at the top. Observing the correct polarity, (positive wire to , terminal and negative wire to . terminal) insert the twisted ends into the open holes (see figure 11) and release the springs to secure them. Push any loose wire back into the wall.
C Do not connect the speaker wires from one channel
in parallel (together) with wires of the other channel on the same terminal.
