User manual EDIFIER R501

[. . . ] Ventilation ---- Do not block the openings in the speaker cabinets, never push objects into speaker vents or slots because of fire or electric shock hazards, and provide sufficient space around the speakers for proper ventilation. Location ---- Place the speakers in a stable location so they will not fall causing damage to the speakers or bodily harm. Cleaning ---- Unplug the speakers from the computer and from the electrical outlet before cleaning them with a damp cloth. [. . . ] 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. If you must use a 2 channel input then this should be connected to the front L and front R input. 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.
