User manual ALTEC LANSING 510 S

[. . . ] Each speaker has its own crossover network. See www. alteclansing. com for additional wiring options. Unpacking Each loudspeaker is wrapped in a protective bag with poly-foam corners and the tweeter/midrange drivers are covered by protective poly-foam. Remove the bag and the poly-foam protection. [. . . ] Uncovered floors, window panes and mirrors can dramatically affect the distribution of higher frequencies. If you can detect reflections (loss of desired stereo effect) of higher frequencies and you suspect the floor may be the problem, placing a rug on the floor close to the speaker may solve the problem. If a window may be the cause of reflections, drapes should solve the problem. The floor and walls act as extensions of the speaker and generally affect low frequency response. Placing the speakers in the corner of a room gives maximum bass response. Also, with the speakers on the floor, maximum response is obtained. Bringing the speakers away from the walls decreases bass. It is obvious that some experimentation will be required to achieve sound to your liking. In many instances adjusting the tone controls (bass-treble) will give the final desired results. Separation The spacing of the speakers from each other affects the stereo stage effect. The angle the speakers face also changes the separation. The best separation (stereo) results are obtained when the speakers are spaced between 8 to 10 feet apart. When adjusting the speaker for separation the listener should be centered about 6 to 8 feet in front of the speakers. Adjust the angle of the speakers until the desired stereo stage is obtained. 3. FIGURE 1 If You Are Having Trouble Your Altec Lansing loudspeakers are precision instruments, responding with high accuracy to the variations in electric current produced by other components in your system. Extraneous noise such as hum, rumble, or hissing do not originate in the loudspeakers.

This means that low power amplifiers (25 watts per channel) will give good results. [. . . ] Stabilizers or "feet" in varying heights are available in high fidelity outlets and raise the cabinet slightly providing smoother bass response.
