Niles OS3 User 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 OS3 connects to your receiver or amplifier using 2-conductor speaker 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 of the OS3 will accommodate up to 12 gauge wire directly.
Larger sizes can be accommodated using spade, banana, or pin connectors.
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.
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.
