DS00426ACN_OS_5.qxp 12/20/04 5:46 PM Page 7 INSTALLATION CONSIDERATIONS Figure 2 Wiring directly from a receiver or amplifier Figure 3 Incorporating a volume control Recommended Amplifier Power For optimum performance, we recommend an amplifier with a power rating of: five (5) to one hundred (100) watts per channel for the 0S 5.5 loudspeaker; five (5) to one hundred twenty five (125) watts per channel for the OS 6.5 loudspeaker; five (5) to one hundred fifty (150) watts per channel for the OS 7.
DS00426ACN_OS_5.qxp 12/20/04 5:46 PM Page 8 INSTALLATION CONSIDERATIONS When using more than one pair, it is usually best to alternate a left channel and then a right channel, so that you have the best possible stereo coverage possible. The position of the loudspeakers and their surroundings play a very important role in how a stereo image is created. You should experiment to find the very best position for your loudspeakers. Here are some guidelines to make the process quick and easy.
DS00426ACN_OS_5.qxp 12/20/04 5:46 PM Page 9 You can control the loudspeaker’s bass output by placement. This is called the boundary effect. You will get more bass response by mounting the loudspeaker directly to a wall or other flat surface (any boundary close to the loudspeaker will reinforce the bass frequencies).
DS00426ACN_OS_5.qxp 12/20/04 INSTALLATION CONSIDERATIONS Nail Mounting 5:46 PM Page 10 Screw Mounting Custom Bracket Mounting Figure 7 The OS loudspeaker can be mounted three ways. 2. The safest and most secure way to mount the loudspeaker is by screwing it to the mounting surface using your own hardware (suitable for the surface you are mounting to) and the bracket supplied with the loudspeaker (See Figure 7). 3.
DS00426ACN_OS_5.qxp 12/20/04 5:46 PM Page 11 The enclosure, the brackets, and the grilles of the 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. Make sure you pick a paint that is appropriate for the mounting location. There are interior and exterior paint types, and even paint for marine uses.
DS00426ACN_OS_5.qxp 12/20/04 5:46 PM Page 12 PAINTING THE LOUDSPEAKER 2. Wipe off the 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. 4. Mask off the threaded inserts on the top and bottom with masking tape. 5.
DS00426ACN_OS_5.qxp 12/20/04 5:46 PM Page 13 Replacing the Grille After the grille dries, carefully fit the grille into its recess so that it is barely in place. Starting with one corner, go around the loudspeaker, pushing the grille in a little bit each time. You should be gentle; the aluminum grille can be bent easily out of shape. You will feel a positive “snap” when it is in place. PAINTING THE LOUDSPEAKER If you are using an applicator or brush and a can of paint, thin the paint first.
DS00426ACN_OS_5.qxp 12/20/04 5:46 PM Page 14 INSTALLATION 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. Hold the bracket so that the loudspeaker wire fits through the large, circular wire hole in the center of the bracket.
DS00426ACN_OS_5.qxp 12/20/04 5:46 PM Page 15 2. Tighten the top knob so it does not vibrate. 3. Remove the bottom knob by unscrewing it from the cabinet. INSTALLATION Attaching the foot (if using the loudspeaker in a free standing mode) 1. Loosen the bracket knobs and remove the bracket from the loudspeaker. 4. Place the supplied shelf stand on the loudspeaker with the two shorter feet towards the front of the loudspeaker (See Figure 10).
DS00426ACN_OS_5.qxp 12/20/04 5:46 PM Page 16 INSTALLATION 5. Connect one stripped wire end to the black and one to the red terminal. Pay attention to the markings on the wire. Each loudspeaker wire must be connected to the amplifier in the same way. 6. If required, attach the safety cable to the loudspeaker enclosure. See Safety First section for details. 7. Verify that the loudspeakers are in-phase as described in the Loudspeaker Phase section. 8. Angle the loudspeaker for the best sound possible. 9.
DS00426ACN_OS_5.qxp 12/20/04 5:46 PM Page 17 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 loudspeakers. It is possible to turn the volume so high that the amplifier runs out of power. This creates “clipping” distortion.
