HKTS200SUB harman/kardon

Subwoofer Level Control: Use this control to adjust the HKTS200SUB’s volume. Turn clockwise to increase the volume; turn counterclockwise to decrease the volume.

Bass Boost Switch: Set this switch to ON to enhance the HKTS200SUB’s low-frequency performance. Set this switch to OFF for normal low-frequency performance.

3 3

Phase Switch: The Phase Switch determines whether the HKTS200SUB’s 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 produced by the subwoofer could be canceled out, reducing bass performance and sonic impact. This phenomenon depends in part on the relative placement of all the speakers in the room. In most cases the Phase Switch should be left in the NORMAL position. However, it does no harm to experiment, and you can leave the Phase Switch in the position that maximizes bass response and impact.

Power On Mode Switch: When set in the AUTO position and when

the Power Switch is set to ON, the HKTS200SUB will automatically

turn itself on when it receives an audio signal, and will enter the standby mode once no audio signal has been received for about 15 minutes. When this switch is set in the ON position, the HKTS200SUB will remain on whether or not it is receiving an audio signal. An LED on the HKTS200SUB’s top panel indicates whether the subwoofer is in the on or standby state:

• When the LED is illuminated white, the HKTS200SUB is turned on.

• When the LED is not illuminated, the HKTS200SUB is in standby mode.

When the Master Power Switch is set to OFF, the LED will not be illuminated, no matter what setting the Power On Mode Switch is in.

External Trigger Input: Use the mini-plug of the supplied combination

LFE and trigger cable to connect the External Trigger Input to the trigger output of another compatible component. Whenever a trigger signal between 3 and 30V (AC or DC) is detected, the HKTS200SUB’s

amplifier will turn on. The HKTS200SUB’s amplifier will turn off after

the trigger signal ceases. Switch is in the AUTO position.)

Line-Level LFE In Connector: Use the LFE (purple) connector of the

(This will occur even when the Power On Mode

supplied combination LFE and trigger cable to connect the Line-Level LFE In to the dedicated subwoofer output of a receiver or preamp/ processor. This input bypasses the HKTS200SUB’s internal crossover circuitry, so it should only be used with a subwoofer output that has been low-pass filtered. If your receiver or preamp/processor does not have a dedicated subwoofer output that is low-pass filtered you should use the HKTS200SUB’s Line-Level L/R In Connectors instead.

Line-Level L/R In Connectors: Use these connectors if your receiver or

preamp/processor does not have digital surround sound decoding or a subwoofer output that is low-pass filtered.

• If your receiver or preamp/processor has a separate subwoofer

output, use the LFE (purple) connector of the supplied combination LFE and trigger cable to connect it to either one of the HKTS200SUB’s 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 adapter’s single end to the unit’s preamp output for that channel. Connect one of the adapter’s dual ends to the main amp input for that channel, and connect the adapter’s other dual end to one of the HKTS200SUB’s Line-Level L/R In Connectors. Repeat with the other Y-adapter, preamp channel, main amp input and HKTS200SUB Line-Level L/R In Connector.

Power Switch: Set this switch in the ON position to turn the HKTS200SUB on. The subwoofer will then either be on or in standby mode, depending on the setting of the Power On Mode Switch .

Power Cord (Non-Detachable): 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 HKTS200SUB. DO NOT plug this cord into the accessory outlets

found in some audio components.

Connecting the Subwoofer to a Receiver or Preamp/Processor With a Dedicated Subwoofer Output

Use this installation method for receivers and preamp/processors that have a dedicated subwoofer output with low-pass filtering (also called bass management). If the dedicated subwoofer output does not have low-pass filtering, follow the instructions in Connecting the Subwoofer to a Receiver or Preamp/Processor With Line Outputs, on page 9.

Use the LFE (purple) connector of the supplied combination LFE and trigger cable to connect the HKTS200SUB’s Line-Level LFE In Jack to the dedicated subwoofer output (or LFE output) of your receiver or preamp /processor.

Connect each satellite speaker and the center speaker to the

corresponding speaker terminals on your receiver or amplifier.

In your receiver or preamp/processor’s setup menu, configure it for Subwoofer ON, and set the front left, front right, center, and surround speakers to Small. After you have made and verified all connections, plug the HKTS200SUB’s AC Power Cord into an active AC outlet.

Connecting the Subwoofer to a Receiver or Preamp/Processor With Line Outputs

Use this installation method for receivers and preamp/processors that do not have a dedicated subwoofer output, but do have preamp-level (volume-controlled) line outputs. If the receiver or preamp/processor has a dedicated subwoofer output with low-pass filtering, see Connect-

ing the Subwoofer to a Receiver or Preamp/Processor With a Dedicated Subwoofer Output, on page 8.

If you’re connecting to a receiver with left and right line outputs that are not connected to amplifier inputs, connect the LFE (purple) connector of the supplied combination LFE and trigger cable to one of those outputs and to either of the HKTS200SUB’s Line-Level L/R In Con- nectors . Use a second RCA cable ( not supplied) to connect the other receiver or preamp line output to the other of the HKTS200SUB’s Line- Level L/R In Connectors .

If you’re connecting to a receiver or preamp /processor with left and right line outputs that are connected to amplifier front left and right

inputs, connect the single ends of Y-adapters (not supplied) to the receiver’s or processor’s left and right line outputs. Connect one of the Y-adapter’s double ends to the HK TS200SUB’s Line-Level L/R In Connectors , and connect the other double end to your amplifier’s front left and right inputs.

Connect each satellite speaker and the center speaker to the corresponding speaker terminals on your receiver or amplifier.

In your receiver or preamp/processor’s setup menu, configure it for Subwoofer ON, and set the front left, front right, center, and surround speakers to Small.

After you have made and verified all connections, plug the HKTS200SUB’s AC Power Cord into an active AC outlet.

Operation

Troubleshooting

Turning the Subwoofer On and Off

Set the HKTS200SUB’s Power Switch to the ON position.

• If the Power On Mode Switch is set to AUTO, the HK TS200SUB will automatically turn itself on when it receives an audio signal, and it will go into standby mode when it has received no audio signal for 15 minutes. The HKTS200 SUB’s LED will illuminate white when the subwoofer is on, and will not be illuminated when the subwoofer is in standby.

• If the Power On Mode Switch is set to ON, the HK TS20 0SUB will remain on at all times. The HK TS200 SUB’s LED will illuminate white.

• If the External Trigger Input Connector is connected to a trigger voltage source, the HKTS200SUB will turn on whenever a trigger voltage is present, and will turn off after the trigger voltage ceases, regardless of the position of the Power On Mode Switch .

If you will be away from home for an extended period of time, or if you will not be using the subwoofer for an extended period, switch the Power Switch to the OFF Position.

Subwoofer Adjustments: Volume

Use the Subwoofer Level Control to set the HKTS200SUB’s volume. Turn the knob clockwise to increase the subwoofer’s volume; turn the knob counterclockwise to decrease the subwoofer’s volume.

Subwoofer Adjustments: Phase

The Phase Switch determines whether the HK TS200SUB’s 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 produced by the subwoofer could be canceled out, reducing bass performance and sonic impact. This phenomenon depends in part on the relative placement of all the speakers in the room.

Although in most cases the Phase Switch should be left in the NORMAL position, there is no absolute correct setting for the Phase Switch . When the HK TS200SUB is properly in phase with the satellite speakers, the sound will be clearer and have maximum impact. This will make percussive sounds like drums, piano and plucked strings sound more lifelike. The best way to set the Phase Switch is to listen to music that you are familiar with and set the switch in the position that gives drums and other percussive sounds maximum impact.

Subwoofer Adjustments: Bass Boost

When set to the ON position, the Bass Boost Switch enhances low-frequency performance, resulting in bass with more impact, which you may prefer while watching movies or listening to music. There is no harm in experimenting with this control – set ting the switch to the OFF position will return normal low-frequency performance.

If there is no sound from any of the speakers :

• Check that the receiver/amplifier is on and a source is playing.

• Make sure that all wires and connections between the receiver/amplifier

and the speakers are connected properly.

• Make sure none of the speaker wires is frayed, cut or punctured.

• Review the proper operation of your receiver/amplifier.

If there is no sound coming from one speaker:

• Check that the balance control on your receiver/amplifier is not set all the

way to one channel.

• Check your receiver /amplifier’s speaker setup procedure to make sur e that

the speaker in question has been enabled and its volume level has not been turned all the way down.

• Make sure that all wires and connections between the receiver/amplifier

and the speaker are connected properly.

• Make sure the speaker wires are not frayed, cut or punctured.

If there is no sound coming from the center speaker:

• Check your receiver /amplifier’s speaker setup procedure to make sur e that

the center speaker has been enabled and its volume level has not been turned all the way down.

• Make sure that all wires and connections between the receiver/amplifier

and the center speaker are connected properly.

• Make sure the speaker wires are not frayed, cut or punctured.

• If your receiver is operating in Dolby

center speaker is not set to Phantom.

If there is no sound coming from the surround speakers:

• Check your receiver /amplifier’s speaker setup procedure to make sur e that

the surround speakers have been enabled and their volume levels have not been turned all the way down.

• Make sure that all wires and connections between the receiver/amplifier

and the surround speakers are connected properly.

• Make sure the speaker wires are not frayed, cut or punctured.

• Review proper operation of your receiver/processor and its surround-

sound features.

• Make sure the movie or TV show you’re watching has been re cor ded in a

surround-sound mode. If it is not, check to see if your receiver/amplifier has a different surround-sound mode that you can use.

• Review the operation o f your DVD player and the DV D jacket to ma ke sure the

DVD features the desired Dolby Digital or DTS and that you have properly selected that mode using both the DV D player’s menu and the disc’s menu.

If there is no sound coming from the subwoofer:

• Check that the subwoofer’s Power Cord is plugged in to a working AC outlet.

• Check that the subwoofer’s Power Switch is in the ON position.

• Check that the Subwoofer Level Control is not turned all the way down

(fully counterclockwise).

• Check the audio connection between your re ceiver/pr ocessor a nd

the subwoofer.

• Check your receiver /amplifier’s speaker setup procedure to make sur e that

the subwoofer has been enabled and its volume level has not been turned all the way down.

If the system plays at low volumes but shuts of f as volume is increased:

• Make sure that all wires and connections between the receiver/amplifier

and the speakers are connected properly.

• Make sure none of the speaker wires is frayed, cut or punctured.

• If you’re using m ore than one p air of main speakers, check to be sure tha t

you’re not operating the system below the receiver/amplifier’s minimum impedance requirements.
