LOW PASS FREQ control should be between 0 6 and 0 9 times that figure The more gradual the low frequency roll off of the satellite soeakers the lower the frequency should be set See the Fine Tuning section for more Fine tuning Home Theatre In home theatre systems the subwoofer LFE signal is a separate channel rather than an extension of the signal to the satellite speakers The LOW PASS FILTER is switched out or set to maximum because the processor provides all the filtering for any speakers set to small However the position of the PHASE switch must still be assessed Normally the phase will be set to 0 but if the subwoofer is positioned at a distance significantly different from the other speakers or the power amplifier driving the other speakers happens to invert the signal the 180 position may be preferable Listen with the switch in both positions and choose the one that gives the fullest sound If there is little difference leave the switch at O Surround sound processors normally have a calibrated noise signal that can be used to set the relative levels of all the speakers making the task somewhat more straightforward than for 2 channel audio However do not be afraid to alter the settings to your personal preference It is all too easy to get carried away with the capabilities of the subwoofer especially with some special low frequency effects Often a more realistic portrayal and one more satisfying

8. d the less hard the subwoofer has to work but there is a down side Subwoofers positioned near corners often generate more low frequency room resonances making the bass more uneven with frequency There is no substitute for experiment as all rooms behave differently so the subwoofer should be tried in a variety of positions before a final decision is made A piece of music with a bass line ascending or descending the musical scale is useful for assessing the smoothness of the bass response Listen for exaggerated or quiet notes If the subwoofer is to be used in a confined space e g built into furniture the soace must be ventilated to allow sufficient air to circulate and cool the unit Ask your dealer for advice The subwoofer is intended to be floor mounted only It is important to ensure the subwoofer stands firmly on the floor using the spike feet supplied whenever possible The spike feet are designed to pierce carpet and rest on the floor surface Initially screw the lock nuts onto the spikes enough to leave the nuts floating just above the carpet when the spikes are resting on the floor beneath Screw the spikes fully into the threaded inserts in the base of the cabinet If the cabinet rocks when placed on the floor unscrew the two spikes that do not touch the floor until the cabinet rests firmly without rocking Finally lock the nuts against the cabinet It may be more convenient to fit and adjust the spike feet after speaker

12. ers three options of subwoofer bass extension Position A gives the greatest extension and position C gives the least extension Position B provides a compromise setting If the system is to be used at very high volume levels or in a large listening room restricting the bass extension by selecting either B or C may help ensure that the subwoofer is not asked to exceed its performance limits In most situations the BASS EXTENSION switch should be left in position A The EQ switch alters the subwoofer bass roll off alignment The bass you hear is a combination of the subwoofer plus the effects of the room and you should choose the position that best complements your room and the location of the subwoofer Position A gives a drier alignment more suited to placing the subwoofer in a corner or compensating for a resonant room Position B is suited to a less resonant room acoustic and use away from a corner If you get problems with uneven bass certain bass notes are exaggerated more than others then you probably have a room interface problem and it is worth experimenting with the location of the subwoofer What may seem like small changes in position 15cm Gin or so can have a profound effect on the sound The use of multiple subwoofers can smooth the effects of room resonances as each subwoofer will tend to excite resonances at different frequencies If you appreciably alter the relative distances from the subwoofer s an
