Installation Considerations - Niles OS7.5 Installation & Operation Manual

INSTALLATION CONSIDERATIONS

Tools and Materials Required
• A wire stripper
• A pencil
• A level (optional)
• Three screws or bolts suitable for the mounting surface
• The proper screwdriver for your mounting hardware
• A drill bit of the right size and type
• An electric drill
Wiring
The OS loudspeakers connect to your receiver or amplifier using 2-conductor
loudspeaker wire (See Figure 2). For most applications, we recommend using 16
or 18 gauge wire. For wiring runs longer than 80 feet, we recommend 14 gauge
wire. The binding posts on OS loudspeakers accommodate up to 12 gauge wire
directly. Larger sizes can be accommodated using spade, banana, or pin
connectors.
TECH TIP
Wire size is expressed by its AWG (American Wire
Gauge) number. The lower the number, the larger
the wire, i.e. twelve AWG is physically larger than
fourteen AWG.
When you run wire inside walls, outdoors or in marine installations, special
jacketing or conduit is required for a trouble-free installation and conformation to
the local and national building codes. If you are not sure of the correct wire jacket
or type of conduit to use, consult a professional audio/video installer, building
contractor, or the local building and inspection department.
Incorporating a Volume Control
It's possible to control the volume of the sound at the loudspeaker location. Plan to
wire the system so that each pair of loudspeakers has its own volume control. Niles
makes a wide range of indoor and outdoor volume controls with and without
muting capabilities. Consult your local Niles dealer for more information. Volume
controls are connected in line with the loudspeaker, so you must connect the wire
from the amplifier to the volume control and then from the volume control to the
loudspeaker (See Figure 3).
