SUBWOOFER CONTROLS AND CONNECTIONS Power Switch Subwoofer Level Control Crossover Control Phase Switch Wireless Pairing Button Wireless Pairing LED Power Cord Connector Subwoofer Level control: Use this control to balance the subwoofer's volume with that of the soundbar. Turn the knob clockwise to increase the subwoofer's volume; turn it counterclockwise to decrease the subwoofer's volume. Crossover control: This knob adjusts the subwoofer's cutoff between 40Hz and 200Hz.The higher you set the Cutoff control, the higher in frequency the subwoofer will operate and the more its bass will "overlap" that of the soundbar. This adjustment helps achieve a smooth transition of bass frequencies between the subwoofer and the soundbar for a variety of different rooms and subwoofer locations. See Subwoofer Crossover control, on page 8, for more information. Phase switch: This switch determines whether the subwoofer driver's piston-like action moves in and out in phase with the speakers in the soundbar. If the subwoofer were to play out of phase with the soundbar speakers, some of the sound waves produced by the subwoofer or soundbar could be canceled, reducing bass performance and sonic impact. This phenomenon depends in part on the relative placement of the speakers in the room. See Subwoofer Phase switch, on page 8, for more information. Wireless Pairing switch and LED: Press this switch to initiate wireless pairing between the subwoofer and the soundbar. See Pairing the Units for Wireless Operation, on page 6, for more information. • The LED lights blue continuously when the subwoofer is on and linked to the soundbar. • The LED slowly flashes blue when the subwoofer is on and the wireless link is not established between the subwoofer and the soundbar. • The LED rapidly flashes blue during the wireless pairing process. Power switch: Set this switch to the "On" position to activate the subwoofer. In normal operation, this switch will be left in the "On" position. See Turning the Subwoofer On and Off, on page 6, for more information. If you will not be using the subwoofer for an extended period - for instance, if you're going on vacation - set the Power switch to the "Off" position. Power Cord connector: Connect the included power cord here and into an active, unswitched AC outlet. See Power Connections, on page 5, for more information. IMPORTANT: Do not connect the power cord to an AC outlet until you have made and verified all other connections. www.jbl.com 3
