Do not bundle or roll the excess cabling. If the connections are faulty, no sound will be heard from the subwoofer or the speakers, or both. Make sure that the + and – polarity markings of the speaker cables are observed and connected correctly. If these cables are reversed, the sound will be unnatural and lack bass. Caution Do not let the bare speaker wires touch each other, because this could damage the subwoofer or the amplifier, or both of them. ¦Before connecting Remove 10 mm (3/8”) of insulation from the ends of the speaker cables. 10 mm (3/8 ”) Good No Good ¦How to connect 1 Loosen the terminal’s knob, as shown in the figure. 2 Insert the bare wire. 3 Tighten the knob. 4 Test the firmness of the connection by pulling lightly on the cable at the terminal. Red: positive (+) Black: negative (–) 2 1 3 U.S.A., Canada and Australia models only Banana Plug connections are also possible. 1 Tighten the terminal knob. 2 Simply insert the banana plug into the terminal 1 2 Plug in the subwoofer to the AC outlet After all connections are completed, plug the subwoofer and other audio/video components into AC outlets. To AC outlet 10 En AUTOMATIC POWER-SWITCHING FUNCTION AUTOMATIC POWER-SWITCHING FUNCTION The subwoofer automatically places itself in standby mode if it does not receive an input signal for 7 or 8 minutes. (The power indicator lights red.) When the subwoofer detects a bass signal input of below 200 Hz, it automatically places itself in power-on mode. (The power indicator lights green.) Notes • This function is available only when the POWER switch and STANDBY/ON button are set to ON. • Noise received from other appliances may extend the time period before the subwoofer places itself in standby mode to more than 8 minutes. Changing the AUTO STANDBY setting 1 Set the subwoofer to standby. 2 Change the AUTO STANDBY setting. - LOW: Select this position to activate this function. - HIGH: If this function does not operate with AUTO STANDBY switch set to LOW, select this position so that the subwoofer detects input signals with a lower level and switches the power on automatically. - OFF: Select this position to deactivate this function, for example, when the subwoofer switches the power on unexpectedly by sensing noises from other appliances. 11 En English ADJUSTING THE SUBWOOFER BEFORE USE ADJUSTING THE SUBWOOFER BEFORE USE 1 Set the VOLUME control to minimum (0). 2 Turn on the power of all the other components. 3 Make sure that the POWER switch is set to the ON position, then press the STANDBY/ON button to turn on the subwoofer. * The Power indicator lights up in green. 4 Play a source containing low-frequency components and adjust the amplifier’s volume control to the desired listening level. 5 Adjust the HIGH CUT control to the position where the desired response can be obtained. Normally, set the control to a level a little higher than the front speaker’s rated minimum reproducible frequency*. * The front speaker’s rated minimum reproducible frequency can be looked up in the speakers’ catalog or owner’s manual. 6 Increase the volume gradually to adjust the volume balance between the subwoofer and the front speakers. Normally, set the control to a level where you can obtain a little more bass effect than when the subwoofer is not used. If the desired response cannot be obtained, adjust the HIGH CUT control and the VOLUME control again. 7 Set the PHASE switch to the position which gives you the better bass sound. Set the switch to the REV (reverse) position. If the desired response cannot be obtained, set the switch to the NORM (normal) position. 8 Select “MOVIE” or “MUSIC” according to the played source. MOVIE: When a movie type source is played, the low- frequency effects are enhanced to allow listeners to enjoy more powerful sound. (The sound will be richer and deeper.) MUSIC: When an ordinary music source is played, the excessive low-frequency components are cut off to make the sound clearer. (The sound will be lighter to reproduce the melody line more clearly.) Notes • Once the volume balance between the subwoofer and the front speakers is adjusted, you can adjust the volume of your entire sound system by using the amplifier’s volume control. However, if you change the front speakers to others, you must make this adjustment again. • For adjusting the VOLUME control, the HIGH CUT control and the PHASE switch, refer to “Frequency characteristics” on page 13. 12 En ADJUSTING THE SUBWOOFER BEFORE USE ADJUSTING THE SUBWOOFER BEFORE USE This subwoofer’s frequency characteristics 20 50 100 200 500Hz 40 50 60 70 80 90 dB HIGH CUT 40 Hz HIGH CUT 90 Hz HIGH CUT 140 Hz The figures below show the optimum adjustment of each control and the frequency characteristics when this subwoofer is combined with a typical front speaker system. ¦EX.1 When combined with 10 cm (4”) or 13 cm (5”) acoustic suspension, 2-way system front speakers dB PHASE 90 NORM REV 80 70 (70Hz) (REV) 60 50 40 20 50 100 200 500Hz Front speaker F...
