Mounting Options On optional stands. Subwoofer Surround Speakers 150-180 cm Satellites and Surrounds one.Speaker Placement Satellites The customer is responsible for proper selection and use of mounting hardware, available through hardware stores, to properly and safely wall-mount the speakers. Always start with the subwoofer as close to one of the front cor- ners as possible to take advan- tage of solid-angle gains. If you get too much bass, adjust the ”VOLUME” towards ”MIN”. The result will be lower distortion and higher reliability. If the excessive bass is at one or more discrete frequencies, then it might be necessary to consider dealing with room modes. Here are your options: Modify the acoustical coupl- ing of the subwoofer to the room boundaries and/or the room modes, i.e. move the subwoofer. Modify the acoustical cou- pling of the listener to the room boundaries and/or the room modes, i.e. move the listener. Move both the subwoofer and the listener.

Speakers and amplifiers/- receivers have corresponding (+) and () terminals. The (+) lead of the speaker wire is noted with a stripe. It is impor- tant to connect all the speakers identically: (+) on the speaker to (+) on the amplifier and () on the speaker to () on the amplifier. Wiring “out of phase” results in thin sound, weak bass and a poor stereo image.

Note: Some receivers/ amplifiers have a single (mono) subwoofer output. In this case, it is recommended that you use a “Y”-connector (not included) to maximize the subwoofers performance. Crossover Frequency The crossover frequency knob determines the highest frequen- cy your subwoofer will reprodu- ce. It allows a seamless transi- tion from the subwoofer to the satellite speakers. Experiment with this adjustment to find the crossover frequency that sounds best with your speakers. When the control is at the ”40Hz“ position, very few high frequencies will be heard. This position is best suited to large main speakers. For most users, the control should be set somewhere near the mid position. For listeners using very small speakers, best results will be obtained with the control at the ”130 Hz“ position. For subwoofers used with Surround Sound processors with dedicated subwoofer out- puts, the best result will be obtained with the control at the ”130 Hz“ position. 4 If there is no sound from any of the speakers, check the following: Receiver/amplifier is on and a source is playing. Powered subwoofer is plugged in and is in the “On” position. Check all wires and con- nections between receiver/ amplifier and speakers. Make sure all wires are connected. Make sure none of the speaker wires are frayed, cut or punctured. Review proper operation of your receiver/amplifier. If there is no sound coming from one speaker, check the following: Check the “Balance” control on your receiver/amplifier. Check all wires and con- nections between receiver/ amplifier and speakers. Make sure all wires are connected. Make sure none of the speaker wires are frayed, cut or punctured. If the system plays at low volumes but shuts off as vol- ume is increased, check the following: Check all wires and con- nections between receiver/ amplifier and speakers. Make sure all wires are connected. Make sure none of the speaker wires are frayed, cut or punctured. If more than one pair of main speakers is being used, check the minimum impedance requirements of your receiver/amplifier. If there is low bass output, check the following: Make sure the connections to the left and right “Speaker Inputs” have the correct polarity (+ and ). Make sure that the subwoofer is plugged into an active elec- trical outlet and is turned on. If there is no sound from the surround speakers, check the following: Check all wires and con- nections between receiver/ amplifier and speakers. Make sure all wires are connected. Make sure none of the speaker wires are frayed, cut or punctured. Review proper operation of your receiver/amplifier and its surround sound features. Make sure the movie or TV show you are watching is recorded in Dolby surround. If it is not, check to see if your receiver/amplifier has other surround modes you may use.
