INTRODUCTION

Niles once again raises the bar. With our first OS Indoor/Outdoor models we revealed a radical new understanding of loudspeaker capabilities. Niles original OS Indoor/Outdoor loudspeakers are constantly praised for their ability to deliver exemplary reliability and outstanding sound quality. These attributes have made Niles OS Indoor/Outdoor loudspeakers the best selling loudspeakers in their class.

The goal of our new OS Indoor/Outdoor line-up is to raise this bar with refined appearance and superior sonic performance. Once again establishing a benchmark by which all others are judged. The new Niles OS Indoor/Outdoor loudspeakers owe much of their performance and sound quality advantage to design elements pioneered in the award-winning Niles DS Directed Soundfield™ loudspeakers. Their engineering advances come from our integrated approach to driver and cabinet design. By integrating the woofer basket into the baffle of the cabinet we are able to increase the woofer cone-area to cabinet-width ratio. Thus enabling OS Indoor/Outdoor loudspeakers to provide levels of bass performance that substantially exceed their physical size. However, deeper and more powerful bass isn’t the only refinement in the new OS Indoor/Outdoor line-up. A new and modern style enables OS Indoor/Outdoor loudspeakers to blend seamlessly with the architectural elements both indoors and out. After the installation is complete, you will be astonished by the experience of hearing such clean and powerful sound coming from such elegant appearing loudspeakers.

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).
