INSTALLATION CONSIDERATIONS

INSTALLATIONCONSIDERATIONS

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).
