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. 

Phase Switch:

 This 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 

  N

ORMAL

 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. (This will occur even when the 

Power On Mode 

    Switch

     is in the 

AUTO

 position.)

Line-Level LFE In Connector:

 Use the LFE (purple) connector of the 

  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.
