[. . . ] If the provided plug does not fit into your outlet, consult an electrician for replacement of the obsolete outlet. Protect the power cord from being walked on or pinched particularly at plugs, convenience receptacles, and the point where they exit from the apparatus. For added protection during lightning storms, unplug the speakers from the electrical outlet and turn off the computer. Unplug this apparatus when unused for long periods of time. [. . . ] If you only have a 2 channel stereo output it may be possible to purchase a Dolby digital 5. 1 decoder which will convert this into a 5. 1 format. This is not included with these speakers. If you must use a 2 channel input then this should be connected to the front L and front R input. This will result in a stereo output only. 1. POSITIONING If you have the 5. 1 surround sound input then you can experience the full performance of this system. You will have the individual outputs for the subwoofer, front stereo, rear stereo and front centre speakers. Position the front stereo speakers in front of the listening position with an equal distance to the left and right sides. Ideally the speakers should be about ear height(when sitting to listen) if possible and slightly away from a rear wall, or they can be hooded onto a wall if necessary. If they are placed on a slippery surface, a little blue-tack may help hold them in place. These speakers contribute a lot to the overall audio so careful placement is crucial to your enjoyment of the music. The centre speaker should be placed on the top of your TV set or your computer monitor(if applicable) as this speaker is used for vocal content. The voices in a movie need to sound as though they are coming from the TV set so try positioning this on top of the set. The rear speakers are used for special effects and are not as crucial in their placement. A good position for these is high up on the wall behind the listening position, perhaps pointing downward a little. The subwoofer houses a powerful bass driver and the positioning of this unit can have an effect on the quality of the bass. If the unit is placed in a corner, the bass will be amplified by the reflection from the walls. This position will give maximum bass but can sound quite boomy. A position near a rear wall but away from the corner is best as this will give a little boost to the bass without being too much. Experiment with the position to achieve best results. Also note that the unit recives the signals from the remote control. The range of transmission from the remote is not too great so don`t position the bass unit too far from the listening position. Switch off the power first before connecting any part of the system. [. . . ] Is computer system's sound (control panel) volume turned up?Distortion or buzzing quality to total sound or subwoofer: Turn down computer's sound (control panel) volume, and increase Control Pod volume. Turn down Subwoofer volume, as program signal may be too strong. Noise or hiss; signal not loud enough with Main Volume turned up : Turn up computer's sound (control panel) volume. [. . . ]
