LightSpeed Technologies 850 - Manual

Step 1: Selecting Speaker
Mounting Locations
Four WMQ ™ Wall Speakers are ideal in rooms up to 1600
square feet with a ceiling height of 8–12 feet.
Before starting the system installation, speaker placement
needs to be decided. Optimum sound pattern is achieved
when the speakers are staggered on the four walls as
shown in figure 1. Speakers should NOT be placed directly
opposite of each other.
Ceiling height determines how high the speaker is set on
the wall. Increased ceiling height allows the speakers to
cover a larger area.
If the classroom is not rectangular, does not have suspend-
ed ceilings, or has a ceiling that is not horizontal (flat), call
LightSPEED Technical Support (800.732.8999) to determine
optimum speaker placement.
Step 2: Mounting the Speakers
A. Identify a suitable location for the receiver/amplifier
where it is easily accessible, close to a power outlet,
and at least 6 feet away from any computers.
B. Remove the mounting bracket from the WMQ speaker
by unscrewing the knobs on the side of the speaker.
C. Use the bracket as a template to mark the position for
the two screws where the bracket will be fastened (see
figure 2). Keeping the bracket as horizontal as possible,
push a sharp object through the template into the wall.
These mark where the wall mounting screws will
be placed.
D. Each speaker bracket comes with two mounting screws,
two washers and two sheet rock mollies.
i. If the walls are wood, screw the mounting bracket
to the wall with two mounting screws and washers at
the marked spacing. Then screws should be inserted
into the wood so that the bracket is held snuggly to
the wall.
ii. If the walls are sheet rock, drill pilot holes (3/16”
to 1/4” diameter) in the sheet rock at the marked
spacing. Screw the two sheet rock mollies into the
pilot holes until they are flush with the surface.
The screws and washers should be inserted into the
mollies so that the bracket is held snugly to the wall.
E. Repeat step B for all speaker locations. Do not attach
the speakers to the brackets yet.
