Unpacking the Subwoofer If you suspect damage from transit, report it immediately to your dealer. Keep the shipping carton and packing materials for future use. SUB RIGHTCHANNEL SPEAKER PLACEMENT Since the installation of a subwoofer can be somewhat more complicated than installation of full-range speakers, it is essential that you read this section very carefully prior to connecting the subwoofer to your system. Should you have questions relating to your installation, it is advisable to call either your dealer or JBL’s Customer Service Department for advice. The performance of the subwoofer is directly related to its placement in the listening room and how you align the subwoofer with its satellite speakers. Setting the volume of the subwoofer in relationship to the left and right speakers is also of critical importance because it is essential that the subwoofer integrate smoothly with the entire system. Setting the subwoofer’s volume level too high will result in overpowering, boomy bass. Setting the volume level too low will negate the benefits of the subwoofer. Here are several additional facts on installation that may prove useful. It is generally believed by most audio authorities that low frequencies (below 125Hz) are nondirectional and, therefore, placement of a subwoofer within any listening room is not critical. While in theory it is true that the larger wavelengths of extremely low frequencies are basically nondirectional, the fact is that, when installing a subwoofer within the limited confines of a room, reflections, standing waves and absorptions generated within the room will strongly influence the performance of any subwoofer system. As a result, specific location of the subwoofer becomes important, and we strongly recommend that you experiment with placement before choosing a final location. Placement will depend upon your room and the amount and quality of bass required (for example, whether or not your room permits placement of the subwoofer near either satellite). PRIMARY LISTENING AREA Figure 1. This example shows the subwoofer positioned behind the right-channel satellite speaker to re-create the actual location of bass instruments in an orchestra and/or add impact to movie soundtracks. 3 Venue Sub10 (120V) OM 2/3/06 11:39 AM Page 6 SPEAKER LEVEL IN LINE LEVEL IN 3 SUBWOOFER LEVEL 4 GREEN: ON RED: STAND-BY 1 0 L R LFE CROSSOVER L 2 R MIN AUTO ON MAX PHASE 0 0 180 0 7 50 Hz 150 5 6 "WAR NING : FOR CONTINUED PROTECTION AGAINST RISK OF FIRE, REPLACE ONLY WITH SAME TYPE T 3. 15A L/250V FUSE" "AVE R TIS S E ME NT: UTILISEZ UN FUSIBLE DE RECHANGE DE MEME TYPE T 3. 15A L/250V" T3. 15A L/250V ™ ® SUB10 ® POWER 8 R RISK OF ELECTRIC SHOCK DO NOT OPEN C A UT IO N NRTL/C CSA 22-2 No. 1 UL 1492 AC 120V~60Hz 250 Watts ¡ Speaker-Level Inputs ™ LFE Input £ Line Inputs ¢ Subwoofer-Level Control ∞ Power Indicator LED § On/Off Auto Switch ¶ Phase Switch • Crossover Adjustment ª Power Switch 4 Venue Sub10 (120V) OM 2/3/06 11:39 AM Page 7 SYSTEM CONNECTIONS If you have a Dolby® Digital or DTS® receiver/processor with a low-frequencyeffects (LFE) or subwoofer output: If your receiver/processor does not have subwoofer outputs for the left and right channels or an LFE output, connect speaker wire from your receiver/ amplifier to your speakers and subwoofer using two sets of speaker wire: SUBWOOFER OR LFE OUTPUT RECEIVER/AMPLIFIER Front Speaker Output IN ANDBY L R 0 0 IN L R "W ARNI :FOR CONTINUED NG PROTECTION AGAINST RISK OF FIRE, REPLACE ONLY WITH SAME TYPE T 3. 15A L/250V FUSE" T3. 15A L/250V If your receiver/processor does not contain a Dolby Digital or DTS processor but has subwoofer outputs: POWER SUB10 NOTE: If your receiver/processor has only one sub out, you may use either the L or R input.

[. . . ] The frequency of maintenance depends on the metals involved in the connections, atmospheric conditions and other factors, but once per year is the minimum. If a problem occurs, make sure that all connections are properly made and clean. If a problem exists in one loudspeaker, reverse the connection wires to the left and right system. [. . . ]
