User manual JBL JBL 6010B

[. . . ] NOTE: The Crossover Control functions only when the Input Mode switch is in the "Normal" setting. On/Standby LED: When the Power switch is in the "On" position, this LED indicates whether the subwoofer is in the On or Standby state: · When the LED glows green, the subwoofer is turned on. · When the LED glows red, the subwoofer is in the Standby mode. Line In/LFE Input Connectors: · When you're connecting the subwoofer to the dedicated subwoofer output of a receiver/processor that has its own low-pass crossover network, use the LFE Input connector and set the Input Mode switch in the "LFE" position. · When you're connecting the subwoofer to the preamp or subwoofer outputs of a receiver/processor that does not have its own low-pass crossover network, use both Line In connectors and set the Input Mode switch in the "Normal" position. [. . . ] If your receiver/processor only has one subwoofer output you can use either Line In connector. Power Switch: Set this switch in the "On" position to turn the subwoofer on. The subwoofer will then be in the Standby mode. It will automatically turn On when an audio signal is detected at its inputs, and will return to the Standby mode when no audio signal is detected its inputs after approximately 10 minutes. If you will be away from home, or will not be using the subwoofer for an extended period, set this switch in the "Off" position to conserve energy. Power Cord Connector: After you have made and verified the subwoofer's input connections, plug the female end of the supplied IEC power cord into the subwoofer's Power Cord connector, and plug the other end of the power cord into an active, unswitched electrical outlet for proper operation of the subwoofer. DO NOT plug the power cord into the accessory outlets found on some audio components. 2 PlacIng the suBwooFer The performance of a subwoofer is directly related to its placement in the listening room and its physical position relative to the other speakers in the system. While it is true that in general our ears do not hear directional sounds at the low frequencies where subwoofers operate, when installing a subwoofer within the limited confines of a room, the reflections, standing waves and absorptions generated within the room will strongly influence the performance of any subwoofer system. As a result, the specific location of the subwoofer in the room does become important to the amount and quality of bass that is produced. To set the Crossover control, listen for the smoothness of the bass. If the bass seems too strong at certain frequencies, try a lower Crossover control setting. If the bass seems too weak at certain frequencies, try a higher Crossover control setting. SubwOOFER aDJuStMEntS: VOLuME Use the Level control to set the subwoofer's volume. Turn the knob clockwise to increase the subwoofer's volume; turn the knob counterclockwise to decrease the volume. Once you have balanced the subwoofer's volume with that of the other speakers in your system, you shouldn't have to change the Level control setting. Notes on Setting Subwoofer Volume: · Sometimes the ideal subwoofer volume setting for music is too loud for films, while the ideal setting for films is too quiet for music. When setting the subwoofer volume, listen to both music and films with strong bass content and find a "middle ground" volume level that works for both. · If your subwoofer always seems too loud or too quiet, you may want to place it in a different location. [. . . ] When setting the subwoofer volume, listen to both music and films with strong bass content and find a "middle ground" volume level that works for both. · If your subwoofer always seems too loud or too quiet, you may want to place it in a different location. Placing the subwoofer in a corner will tend to increase its bass output, while placing it away from any walls or corners will tend to lessen its bass output. SubwOOFER aDJuStMEntS: PhaSE The Phase switch determines whether the subwoofer driver's piston-like action moves in and out in phase with the satellite speakers. [. . . ]
