INSTALLATION CONSIDERATIONS DS00215A/OS6 Manual 3/1/99 9:19 AM Page 9 PLACING THE OS6 FOR THE BEST SOUND QUALITY The OS6’s dispersion pattern 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 spots” of loud sound when you are near the speakers. The best way to avoid hot spots fo

INSTALLATION CONSIDERATIONS DS00215A/OS6 Manual 3/1/99 9:19 AM Page 14 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. To 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 least one-half the listening distance apart (this maintains a large, pleasant st

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). Nail Mounting Screw Mounting OmniMount or Custom Bracket Mounting Figure 7 The OS6 can be mounted three ways. 2. The safest and most secure way to mount the speaker is by screwing it to the mounting surface using your own hardware (su

PAINTING THE OS6 DS00215A/OS6 Manual 3/1/99 9:19 AM Page 12 PAINTING THE OS6 The enclosure, the brackets, and the grilles of the OS6 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 are interior and exterior varieties, and even paint for marine uses. If you are not sure wh

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.

PAINTING THE OS6 DS00215A/OS6 Manual 3/1/99 9:19 AM Page 10 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 aluminum grille can be easily bent out of shape. You will feel a positive “snap” when it is f

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 surroundings (use a level for accuracy). 3. Mark the locations of the three oval-shaped screw

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 plated connectors should be used outside as they will not tarnish or corrode. 4. Use the brac

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 working together or “in-phase”. FINAL ADJUSTMENTS 1. After checking that the speaker is in

OPERATION DS00215A/OS6 Manual 3/1/99 9:19 AM Page 6 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 speaker. It is possible to turn the volume so high that the amplifier runs out of power. This creates “clipping” distortion. Clipping distortion makes treble sound very harsh and unmusica
