OPTIONAL MOUNTING KITS
Williams Sound offers two optional mounting kits for use with the SoundFocus FM System.
Use the SB-3 Wall/Ceiling Mount Kit to mount an R800 Receiver or SPK 800 Speaker to a
wall or ceiling. The SS-3 Floor Stand Kit includes an adjustable stand and flange which
allow you to elevate the R800 or SPK 800 as you choose. To order these optional compo-
nents, contact your dealer or Williams Sound Corp.
INSTALLING THE SB-3 WALL/CEILING MOUNT KIT
1. Use the 5/32" allen wrench to loosen the tension screw in the Clamp Assembly
enough to release the ball. DO NOT unscrew the tension screw completely.
2. Position the Clamp Plate LENGTHWISE on the BOTTOM of the R800 Receiver or
SPK 800 Speaker. (See Figure 15.) Mark TWO hole locations for drilling.
3. Using your hole markings as a guide, drill TWO pilot holes using a 3/16" bit.
Caution: The receiver/speaker walls are 1/4" thick. Drill only deep enough to
pass through the enclosure wall and no more than 1".
4. Attach the Clamp Plate to the receiver/speaker, using the two screws provided.
5. Using the Wall/Ceiling Mounting Plate as a template, mark TWO holes on the wall,
ceiling, or other surface upon which you will be mounting the R800 or SPK 800. (See
Figures 16 and 17.)
6. Drill TWO pilot holes.
7. Use fasteners appropriate for the mounting surface (wood screws, lag bolts, wall
anchors) to attach the Mounting Plate. Recommended fastener size is 1/4".
8. Place the Receiver–Clamp Plate Assembly onto the the Mounting Plate ballshaft. Aim
the receiver/speaker at the desired angle and support it fully while using the hex
wrench to tighten the tension screw.
After initial installation, the ball will slowly compress under pressure. Check the ten-
sion screw after 15 minutes and re-tighten if necessary. DO NOT OVER TIGHTEN.
