6 Additional information About the Speaker System Precautions • Do not place heavy or large objects on top of the speaker. Doing so could provoke the speaker to fall, causing damages or bodily injury. • Do not place the speaker on an unstable surface, as doing so may cause the speaker to fall and cause damage or bodily injury. • Switch off and unplug your AV equipment and consult the instructions when connecting up components. Make sure you use the correct connecting cables. • Do not sit or stand on the speaker, or let children play on the speaker. Doing so could provoke the speaker to fall, causing damages or bodily injury. • Be careful to make sure children not to put their hands or any objects into the speaker duct*. *Speaker duct: A hole for plentiful bass sound on speaker cabinet (enclosure). • Place the center speaker at a safe distance from the child's reach. Otherwise it may result in the speaker falling down and causing personal injury and/or property damage. • Install the subwoofer in a well-ventilated location where it will not be exposed to high temperatures and high humidity. • Do not place the subwoofer near stoves or other heating equipment or at locations exposed to direct sunlight, as these can have an adverse effect on the cabinet and internal components. Also, do not install the unit where there is too much dust or high humidity, as these can cause malfunctioning or breakdowns. (Avoid cooking tables and other locations where the unit would be exposed to heat, steam and soot.) • Keep the subwoofer away from devices such as cassette decks which are sensitive to magnetic fields. • Do not place cups, glasses, or other containers with fluids on top of the units, since the units may be damaged if the liquid spills. • The installation location selected should have a sturdy floor surface. Mounting the subwoofer on a long-pile carpet should be avoided, since the carpet may touch the driver's diaphram, causing distorted sound. • Please install the subwoofer away from the antenna cable of the receiver, as noise can be caused with installation close to the antenna cable. In such a case, use the subwoofer at a position away from the antenna and the antenna cable, • The front grilles on front/center/surround speakers cannot be removed. Do not try to forcibly remove them since doing so may damage the grille. • When mounting front speakers or surround speakers on a wall surface, make sure that the wall you intend to mount the speakers on is strong enough to support them. When attaching the speakers to brackets, always use the furnished brackets for wall mounting. • Do not attach center speaker and subwoofer to the wall or ceiling, as they may cause injury in the event of a fall. • Do not connect the supplied subwoofer to any amplifier other than the one supplied with this system. Connection to any other amplifier may result in malfunction or fire. • Front/Center/Surround speakers incorporate autoregression technology to protect the speakers. If the speakers stop emitting noise when receiving too large a signal, turn the volume down on the receiver and wait a few seconds. The protection feature disables itself automatically. Effective Combination of Subwoofer and Front/ Center/Surround speakers • When the subwoofer is combined with Front/Center/ Surround speakers in a total system, the sound characteristics produced are like those shown in the accompanying graph, depicting the enhancement of the bass frequencies. This is particularly effective for reproducing ground rumbles and other deep sound effects found in movies. 2 4 34 Front/Center/Surround Speakers + Subwoofer Response(dB) Only Front/Center/Surround Speakers Frequency(Hz) Operation • Set the receiver's cross-over frequency at 200 Hz.
