If the subwoofer were to play out of phase with the satellite speakers, the sound waves from the satellites 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 all the speakers relative to each other in the room. Bass Boost Switch: Set this switch to “On” to enhance the subwoofers low-frequency performance. Set this switch to “Off” for normal low-frequency performance.Power-On Mode Switch: When this switch is set in the “Auto” position and when the Power Switch is set to “On,” the subwoofer will automatically turn itself on when it receives an audio signal and will enter the Standby mode when it has gone without receiving an audio signal for 20 minutes. When this switch is set in the “On” position, the subwoofer will remain on whether or not it is receiving an audio signal.When the Power-On Mode Switch is in the “Auto” position, the LED light next to the switch indicates whether the subwoofer is in the On or Standby mode:When the LED glows blue, the subwoofer is in the On mode. When the LED is off, the subwoofer is in Standby mode. When the Power Switch is set to “Off,” the LED will not light up, no matter what setting the Power-On Mode Switch is in.Subwoofer Level Control: Use this control to adjust the subwoofers volume. Turn the knob clockwise to increase the volume; turn the knob counterclockwise to decrease the volume.External Trigger Input Connector: Use the mini-plug of the supplied combination LFE and trigger cable to connect the External Trigger Input Connector to the trigger output of another compatible component. Whenever the subwoofer amplifier detects a trigger signal between 3V and 30V (AC or DC) the amplifier will turn on. The subwoofer amplifier will turn off after the trigger signal ceases, even when the Power-On Mode Switch is in the “Auto” position.Line-Level In LFE Connector: This input bypasses the subwoofers internal crossover circuitry, so use it only with a receiver or processor subwoofer output that has been low-pass filtered. If your receiver or processor does not have a dedicated subwoofer output that is low-pass filtered, you should use the subwoofers Line-Level In L/R Connectors instead (see below).Use the supplied LFE cable (the one with purple connectors) to connect the Line-Level In LFE Connector to the dedicated subwoofer output of a receiver or preamp/processor.Line-Level In L/R Connectors: These inputs pass through the subwoofers built-in crossover. Use them if your receiver or preamp/processor does not have a dedicated subwoofer output that is low-pass filtered.If your receiver or preamp/processor has a subwoofer output, use the supplied LFE/trigger cable to connect it to either one of the subwoofers Line-Level L/R In Connectors.If your receiver or preamp/processor does not have a separate subwoofer output, use two Y-adapters (not supplied). Connect an adapters single end to the units preamp output for that channel. Connect one of the adapters dual ends to the main amp input for that channel, and connect the adapters other dual end to one of the subwoofers Line-Level L/R In Connectors. Repeat the process with the other Y-adapter, preamp channel, main amp input and subwoofer Line-Level L/R In Connector.Power Switch: Set this switch in the “On” position to turn the subwoofer on. The subwoofer will then be in either On or Standby mode, depending on the setting of the Power-On Mode Switch.Power Cord: After you have made and verified all subwoofer and speaker connections described in this manual, plug this cord into an active, unswitched electrical outlet for proper operation of the subwoofer. DO NOT plug this cord into the accessory outlets found in some audio components.PL0004-01001SubwooferLevel ControlBass BoostSwitchPhase SwitchPower On ModeSwitchExternal TriggerInput ConnectorLine-Level InLFE ConnectorLine-Level InL/R ConnectorsPower SwitchPower CordSubwoofer Rear-Panel Connectionsharman/kardonSB 10 / 230V Service ManualPage 3 of 167SB 10Speaker PlacementSpeaker PlacementPlacing the Soundbar on a Table If your TV is placed on a table, you can place the soundbar on the table directly in front of the TV stand, centered with the TV screen. As long as the surface of the table is flat, the soundbar will rest on its rubber bumpers.If your TV is located in an entertainment or media center, you can mount the soundbar in a space directly above or below the TV.Warning: Do NOT place the soundbar directly on top of a TV or at the front of a table or cabinet. It could roll forward and injure someone.Wall-Mounting the SoundbarIf your TV is attached to a wall, you can use the included wall-mount brackets to mount the soundbar on the wall directly below the TV screen.Determine the location for the soundbar on the wall. Make sure that the top 1. of the soundbar will not block your view of the TV screen when it is mounted on the wall.Mark the locations of the soundbar wall-mount bracket holes on the wall. The 2. holes for the left and right brackets are spaced 600mm (23-5/8) apart. The top and bottom holes for each bracket are spaced 25mm (1) apart. See the illustration below.NOTE: To ensure that the soundbar will be level, use a carpenters level, laser sight or other device to help you determine that the two sets of holes are at exactly the same height.Attach the two wall-mount brackets to the wall at the locations you marked, using hardware that is appropriate for the walls construction and materials. Note that the soundbar weighs 3.67kg (8.1 lb). Be sure to use hardware that can support this weight.After making all of the connections described in the Connections section, on page 8, attach the soundbar to the brackets by sliding the slots in its rubber bumpers onto the brackets vertical tabs.Placing the SubwooferSince our ears cannot locate the source of sounds at the low frequencies that the subwoofer produces, it will perform well from just about any location in your room. However, you are likely to hear the strongest bass reproduction when you place the subwoofer in a corner along the same wall as the soundbar. You can determine the best location for the subwoofer by temporarily placing it in the listening position and playing music with strong bass content. Move around to various locations in the room while the system is playing, and listen until you find the location where the bass performance is best. Place the subwoofer in that location.SB 10 SoundbarListening PositionSubwoofer600mm25mm(not to scale)harman/kardonSB 10 / 230V Service ManualPage 4 of 168SB 10Connections+FRONTLEFT+SURROUNDRIGHTCENTERLCR+Speaker Wires(included)SB 10 SoundbarReceiver or AmplifierConnectionsCAUTION: Before making speaker connections, be sure that your receiver or amplifier is turned off. If possible, make sure that its AC cord is unplugged from the AC power outlet.Soundbar ConnectionsThe SB 10 soundbar contains left-, center- and right-channel speakers that connect to your audio/video receiver or amplifiers front left, center and front right speaker outputs.To connect each wire to the soundbar:Press down on the terminal cap to open the connection hole on the soundbars 1. speaker terminal.Insert the wires bare end all the way into the hole. Insert the conductor with the 2. colored band into the speakers red (+) terminal, and insert the other conductor into the speakers black () terminal, as shown in the illustration.Release the cap to secure the wire.3. IMPORTANT: Make sure the (+) and () bare wires do not touch each other or the other terminal. Touching wires can cause a short circuit that can damage your receiver or amplifier.Subwoofer Connections1a. If your receiver/processor has a dedicated subwoofer output with low-pass filtering (also called bass management), use the included LFE cable to connect the subwoofers Line-Level LFE In jack to the dedicated subwoofer output (or LFE output) of your receiver or preamp/processor. Configure your receiver or preamp/processors setup menu for Subwoofer ON, and set the front left, front right, center and surround speakers to Small.+1. Push Down onCap to Open Hole2.

If your receiver/processor does not have a dedicated subwoofer output but does have preamp-level (volume-controlled) line outputs, use the included LFE cable to connect one of those outputs to either of the subwoofers Line-Level L/R In Connectors. Use an RCA cable (not supplied) to connect the other receiver or preamp line output to the other subwoofer Line-Level L/R In Connector.If youre connecting to a receiver or preamp/processor with left and right line outputs that are connected to front left and front right amplifier inputs, connect the single ends of Y-adapters (not supplied) to the receiver or processors left and right line outputs. Connect one of the Y-adapters double ends to the subwoofers Line-Level L/R In Connectors, and connect the other double end to your amplifiers front left and front right inputs. 2. After you have made and verified all other connections, plug the subwoofers Power Cord into an active, unswitched AC outlet.

The subwoofers LED will glow blue when the subwoofer is on, and will not light up when the subwoofer is in Standby mode.If the Power-On Mode Switch is set to “On,” the subwoofer will remain on at all times. The subwoofers LED will glow blue.If the External Trigger Input Connector is connected to a voltage source, the subwoofer will turn on whenever the source generates a trigger voltage and will go into Standby mode 10 to 15 minutes after the trigger voltage ceases, regardless of the position of the Power-On Mode Switch.If you will not be using the subwoofer for an extended period, set the Power Switch to the “Off” position.Subwoofer Adjustments: VolumeUse the Subwoofer Level Control to set the subwoofers volume. Turn the knob clockwise to increase the subwoofers volume; turn the knob counterclockwise to decrease the volume. Once you have balanced the subwoofers volume with that of the other speakers in your system, you shouldnt have to change it.Subwoofer Adjustments: PhaseThis switch determines whether the subwoofer drivers piston-like action moves in and out in phase with the satellite speakers. If the subwoofer were to play out of phase with the satellite speakers, the sound waves from the satellites could cancel out some of the sound waves from the subwoofer, reducing bass performance and sonic impact. This phenomenon depends in part on the placement of all the speakers relative to each other in the room. Although in most cases you should leave the Phase Switch in the “Normal” position, there is no absolutely correct setting for the Phase Switch. When the subwoofer is properly in phase with the satellite speakers, the sound will be clearer and have maximum impact, and percussive sounds like drums, piano and plucked strings will sound more lifelike. The best way to set the Phase Switch is to listen to music that you know well and set the switch in the position that gives drums and other percussive sounds maximum impact.Subwoofer Adjustments: Bass BoostWhen set to the “On” position, the Bass Boost Switch enhances low-frequency performance. The results: bass with more impact, which you may prefer while watching movies or listening to music. There is no harm in experimenting with this control. Setting the switch to the “Off” position will return the subwoofer to its normal low-frequency performance.harman/kardonSB 10 / 230V Service ManualPage 7 of 1611SB 10TroubleshootingTroubleshootingThis unit is designed for trouble-free operation.
