Setup And Adjustment - Work Pro W NEO S 8A Manual De Uso

Positioning THE NEO S8 A Subwoofer
Your new subwoofer will work well in a variety of locations. However, placement in your listening room will affect its
performance. Since the wavelengths of sound reproduced by your subwoofer are large compared to its size, those
sounds are omni-directional in nature. This means that locating your subwoofer in relation to your left and right main
speakers will not affect the directional cues which they provide. Because the sound you hear is combination of direct
sound from the speaker and reflected sound from the wall, ceiling and floor of your listening room, placement of the
subwoofer in relation to room boundaries changes the balance of what you hear at low frequencies. In that low frequency
range, the dimensions of most rooms are comparable to the wavelengths of those sounds. As sound propagates and
reflects in the room, "standing waves" are created at frequencies where the wave length of sound or multiples of the
wave length are equal to one of the dimensions of the room. At your listening position, these standing wave patterns of
reflected sound add together in and out of phase causing large variations in the response that you hear. As a general
rule, locating your subwoofer near the corner of the room will increase its overall output, but will excite more standing
waves in the room and may result in a more uneven response. Locating your subwoofer along a wall will usually mean
less acoustic output but a somewhat smoother response. A middle of the room location would suggest the smoothes
response with the least output capability. Of course, any location will be a compromise between acoustic performance
and the aesthetic blend of the subwoofer enclosure with the decor and furnishing of your room. Do not be afraid to
experiment with the location of your subwoofer in your room for the best results at your listening position. As with any
other listening test, use program material that you are familiar with that has substantial bass content.

Setup and Adjustment

After you have selected an initial location for your subwoofer and have connected it into your system, have a seat
in your normal listening position and have someone help you with the following adjustments:
A) If you are using the line level inputs and your main speakers are receiving a full range signal, set the subwoofer
crossover frequency control to its full counterclockwise position of 50 Hz.
B) Set the gain control to the full counterclockwise position at "Minimum".
C) Turn off the loudness control and set the bass tone contrl on your main amplifier to the flat position.
D) Use familiar program material that has substantial bass content and play your main system at a moderate
volume level.
E) Slowly rotate the subwoofer level control clockwise until a good balance is achieved between the low frequency
output of your subwoofer and the mid bass and upper frequencies from your main speakers.
F) Slowly rotate the subwoofer crossover frequency control clockwise to attain the best blend between the level of
the subwoofer and the main speakers in the midbass croosover region. Advancing the control too far will cause a
"boominess" in the overall sound and will add an unnatural "chesty" quality to voices.
