SB 16 Subwoofer Rear-Panel Controls Subwoofer Rear-Panel Connections Crossover Knob Volume Knob Phase Switch Wireless Code Switch AC Fuse Power Cord Power Switch Crossover Knob: This knob adjusts the subwoofer's crossover between 50Hz and 150Hz. The higher you set the Crossover knob, 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 Knob, on page 10, for more information. Volume Knob: 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. 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, the sound waves from the soundbar could cancel out some of the sound waves from the subwoofers, reducing bass performance and sonic impact. This phenomenon depends in part on the placement of the subwoofer and soundbar relative to each other in the room. See Subwoofer Phase Switch, on page 10, for more information. Wireless Code Switch: Selects between four different channels for the wireless subwoofer signal. IMPORTANT: Be sure to set the soundbar's Wireless Code switch to the same channel as you set the subwoofer's Wireless Code switch. See Wireless Code Switches, on page 10, for more information. AC Fuse: The SB 16 SUB is factory-equipped with a T1.6AL/250V AC fuse. If the fuse ever blows: 1. Unplug the power cord from the wall. 2. Use a screwdriver to remove the blown fuse. 3. Replace the fuse with an identical T1.6AL/250V AC fuse. CAUTION: FOR CONTINUED PROTECTION AGAINST FIRE, REPLACE THE FUSE ONLY WITH THE SAME TYPE AND RATING. Power Cord: Plug this cord into an active, unswitched AC outlet. See Power Connections, on page 8, for more information. 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 9, for more information. Status Indicator (on top of unit, not shown): Turns blue when the subwoofer's power switch is in the On position; turns amber when the subwoofer is in Standby; turns off when the subwoofer's Power switch is in the Off position. 5
