INCORPORATING A VOLUME CONTROL It’s possible to control the volume of the sound at the speaker location. Plan to wire the system so that each pair of speakers has its own volume control. Niles makes a wide range of indoor and outdoor volume controls. Consult your local Niles dealer for more information. Volume controls are connected in line with [...]

PLACING THE OS3 FOR THE BEST SOUND QUALITY The OS3 ’s dispersion patter n is very broad. The speaker is very sensitive and will handle a lot of amplifier power. This allows good sound quality over an extremely large listening area. However, if a single pair is positioned to provide coverage of a very large room or patio, you will have “hot spot[...]

Make sure you are not blocking or reflecting the sound off of furniture or other objects. You should have a direct line of sight with the front of the speaker. T o determine the best position, measure the distance between the ideal listening position and the wall you plan to mount the speakers on. Try to place the speak- ers so that they are at lea[...]

1. If the speaker is never going to be exposed to sudden accidental impacts, wind, waves or earthquakes you can simply hang it on a nail using the nail hole(s) of the bracket (See Figure 7) . 2. The safest and most secure way to mount the speaker is by screwing it to the mounting surface using your own hardware (suitable for the surface you are mou[...]

P AIN TIN G TH E OS3 The enclosure, the brackets, and the grilles of the OS3 can all be painted to match the surroundings. Because we want you to preserve the acoustic quali- ties of the grille, please paint the grille according to the grille painting instruc- tions. Make sure you pick a paint that is appropriate for the mounting location. There ar[...]

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 speakers 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. 4. Mask off the threaded inserts on the top and bott[...]

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. REPLACING THE GRILLE Carefully fit the grille into its recess so that it is barely in place. Starting with one corner, go around the speaker, pushing the grille in a little bit each time. You should be gentle, the alumin[...]

INST ALLA TION MOUNTING THE BRACKET 1. Remove the bracket knobs and the bracket from the speaker. 2. Hold the bracket up to the mounting surface. The speaker can be mounted either horizontally or vertically. Hold the bracket so that the speaker wire fits through the large, circular wire hole in the bracket. Align the bracket to be square with the s[...]

CONNECTING THE SPEAKER 1. Separate the two conductors of the speaker 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 speaker wire. 3. If you have any connectors (gold pins or bananas) which you prefer to use, affix them to the stripped wire ends now. Only gold p[...]

3. Stand so you are the same distance from each speaker and listen to the rich- ness of the bass and the loudness of the sound. 4. Turn off the amplifier and reverse the connections on one speaker only. 5. Repeat the listening test with the same setting of the volume control. When the sound has a richer bass and is slightly louder the speakers are [...]

OP ERA TION LISTENING AT HIGHER VOLUMES Significantly more power is required to achieve a reasonable level of volume when speakers are installed outdoors. The two primary reasons for this are that when listening outdoors, there are no walls to reflect and contain the sound and listeners often find themselves further from the speakers. Trying to com[...]
