1. PLACING THE LOUDSPEAKER FOR THE BEST SOUND QUALITY CONTINUED Make sure furniture or other objects will not block or reflect sound from the loudspeaker You should have a direct line of sight with the front of the loudspeaker Figure 5 Illustration depicts the optimum placement zone for a listening distance of 10 feet 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 OS loudspeaker directly to a wall or other flat surface any boundary close to the loudspeaker will reinforce the bass frequencies You can increase the bass output even more by mounting the OS loudspeaker in a corner or under an eave see Figure 6 on the next page This type of placement gives the loudspeaker two boundaries both reinforcing the bass sounds Of course if you wish to hear less bass try moving the loudspeaker away from the boundary see Figure 7 on the next page Figure 6 Placement for more bass output Figure 7 Placement for less bass output MOUNTING METHODS The OS loudspeaker should be mounted horizontally The bracket knobs will keep the loudspeaker angled correctly in any position once they are tightened You can choose from three mounting methods to attach the OS loudspeaker to the wall c2.

5. e Ifthe music is softer now revert to the original connections 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 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 This creates clipping distortion Clipping distortion makes treble sound very harsh and unmusical When you hear harsh sounding treble from any good loudspeaker indoors or outdoors turn the volume down immediately Those harsh sounds are masking some much more powerful ultra high frequency sound spikes which will quickly damage any fine loudspeaker CLEANING Clean the OS loudspeaker with a dampened soft cloth or paper towel If the loudspeaker is mounted high up on a wall or ceiling use a broom to gently brush it off Hosing off the loudspeaker is not recommended as the tweeter is a precise mechanism which might be damaged by a high pressure stream of water NILES AUDIO CORPORATION 1 800 BUY HIF 17 SPECIFICATIONS 0S6 3Si Loudspeaker Driver Complement 6 summing woofer Two independent 1 Ultrasilk dome tweeters with fluid cooling Recommended Amplifier Power 5 to 125 watts per channel Nominal Impedance 8 ohms per channel wired in stereo or 4 ohms with both channels wired togeth
6. 3 Wiring directly from Figure 4 Incorporating a receiver or amplifier volume control RECOMMENDED AMPLIFIER POWER For optimum performance we recommend amplifiers with the following power ratings For the 05 5 3Si loudspeaker 5 to 100 W per channel e For the OS 6 3Si loudspeaker 5 to 125 W per channel Ironically most speakers are not damaged by large amplifiers but by small amplifiers If you are playing at high volume a small amplifier will run out of power very quickly When an amplifier runs out of power it creates damaging clipping distortion A large amplifier will play at the same volume without distorting See OPERATION on page 17 for more information about Clipping distortion PLACING THE 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 However in some applications this is not possible especially when a large area of coverage is required It was for these types of applications that the OS Si loudspeaker was created With its ultra wide dispersion pattern a single OS Si loudspeaker is able to project quality summed stereo sound over a larger area No matter where you are you are always in the sweet spot See Figure 5 on the next page CONTINUED ON NEXT PAGE NILES AUDIO CORPORATION 1 800 BUY HIF 7
