It’s possible to control the volume of the sound at the loudspeaker location. Plan to wire the system so that each loudspeaker has it’s own volume control. Niles makes a wide range of indoor and outdoor volume controls. Consult your local Niles dealer for more information.

Figure 4 Illustration depicts the optimum placement zone for a listening distance of ten feet. Placing the OS Loudspeaker for the Best Sound Quality Traditionally, when using a pair of stereo loudspeakers, the listener will be positioned directly between the left and right loudspeakers to achieve optimum stereo sound.

You can control the loudspeakers bass output by placement. This is called the boundary effect. You will get more bass response by mounting the OS loudspeaker directly to a wall or other flat surface (any boundary close to the loudspeaker will reinforce the bass frequencies).

Top View Nail Mounting Custom Bracket Mounting Screw Mounting Figure 7 The OS loudspeaker can be mounted three ways. 3. There is a threaded brass insert (1/4" – 20) on the back of the OS loudspeaker for attaching a custom bracket (See Figure 7). This allows you to position the loudspeaker at unusual angles or varying distances from the mounting surface.
PAINTING THE LOUDSPEAKER The enclosure, the brackets, and the grilles of the OS loudspeaker can all be painted to match the surroundings. Because we want you to preserve the acoustic qualities of the grille, please paint the grille according to the grille painting instructions.

2. Wipe off the other sides of the cabinet, the bracket, bracket knobs, and grille with a damp cloth. Do not touch or rub the loudspeakers on the front baffle. Make sure everything is dry before masking. 3. Mask off the binding posts and the brass threaded inserts on the back panel with masking tape.

If you are using an applicator or brush and a can of paint, thin the paint first. Thick paint will tend to clog the grille holes. To ensure a uniform appearance, paint the front and back of the grille. Replacing the Grille Carefully fit the grille into its recess so that it is barely in place.
INSTALLATION Mounting the Bracket (if attaching the loudspeaker to a wall, ceiling, beam or other solid structure) 1. Loosen the bracket knobs and remove the bracket from the loudspeaker. 2. Hold the bracket up to the mounting surface. The loudspeaker can be mounted either horizontally or vertically.

Connecting the Loudspeaker 1. Separate the two conductors of each loudspeaker wire so that at least two inches of each conductor are free. 2. Strip one half inch of insulation from the end of each conductor of the loudspeaker wires. 3.

9. Tighten the bracket knobs using only your hands. Use of any power tools may over-tighten the knob, and strip the threads of the insert. 10. Check that the entire installation is safe and secure. Loudspeaker Phase Loudspeaker wire has two conductors. One conductor is attached to the negative (-) terminals and one conductor is attached to the positive (+) terminals of both your loudspeaker and your amplifier.
OPERATION Listening at Higher Volumes Outdoors there are no walls to reflect and contain the sound. It requires more power to achieve a reasonable volume of sound outside than it does when you are indoors. You also frequently find yourself very far from the loudspeaker. It is possible to turn the volume so high that the amplifier runs out of power.
