Subwoofer Controls and Connections
Remote Control Input/Output: If the HS 2X0SO/230’s front-panel IR
sensor is blocked, such as when it is placed inside of a cabinet, con-
nect an external IR receiver (such as the Harman Kardon HE 1000 – not
included) to the Remote Control In connector. You can then place the
external IR receiver in a location where it can receive the signals from
the HS 2X0SO/230 remote control.
You can connect the HS 2X0SO/230’s Remote Control Out connector to
the remote IR input of a compatible device, allowing it to be controlled
through the HS 2X0SO/230 (and through an external IR receiver, if
connected). You can even connect several such compatible devices
together in “daisy-chain” fashion.
SCART Connection: Connect it to a compatible TV or set-top box
using the included SCART cable. The SCART cable carries composite
(CVBS) video or S-Video from the HS 2X0SO/230 to a TV or set-top box
(as well as a control signal for automatically controlling picture aspect
ratio and other parameters). It also carries stereo audio from the
TV or set-top box back to the HS 2X0SO/230.
Composite-Video Output: Connect it to the composite-video input
of a TV or video projector.
S-Video Output: Connect it to the S-Video input of a TV or
video projector.
FM Antenna Connection: Connect the supplied FM antenna to
this terminal.
Subwoofer Level Control: Use this control to adjust the HKTS200SUB
subwoofer’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 subwoofer’s
low-frequency performance. Set this switch to Off for normal
low-frequency performance.
Phase Switch: This switch determines whether the subwoofer driver’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 from the satellite speakers could cancel out
the sound waves from the subwoofer, 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 absolutely correct setting for it. When the
subwoofer is properly in phase with the satellite speakers, the sound
will be clearer and have maximum impact. It 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
know well and set the switch in the position that gives drums and other
percussive sounds maximum impact.
Power On Mode Switch: When this switch is set in the Auto
position and when the Power switch is set to On, the HKTS200SUB
will automatically turn itself On whenever it receives an audio signal.
It will enter the standby mode if it receives no audio signal for 20
minutes. When the Power On Mode switch is set in the On position, the
subwoofer will remain on whether or not it is receiving an audio signal.
An LED on the subwoofer’s top panel indicates whether the subwoofer
is in the on or standby mode:
• When the LED is illuminated blue, the subwoofer is turned on.
• When the LED is not illuminated, the subwoofer is in standby mode.
When the 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 Connector: 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 the
subwoofer detects a trigger signal between 3V and 30V (AC or DC), the
subwoofer’s amplifier will turn on. The subwoofer’s amplifier will turn
off after the trigger signal ceases. (This change will occur even when
the Power On Mode switch is in the Auto position.)
Line-Level In LFE Connector: Use the LFE (purple) connector of
the supplied combination LFE and trigger cable to connect the
Line-Level In LFE connector to the dedicated subwoofer output of a
receiver or preamp/processor. This input bypasses the subwoofer’s
internal crossover circuitry, so use it only with a subwoofer output that
is low-pass filtered. (Check the receiver or preamp/processor’s
documentation to confirm that its subwoofer output is low-pass
filtered.) If your receiver or preamp/processor does not have a
dedicated subwoofer output that is low-pass filtered, use the
subwoofer’s Line-Level In L/R connectors instead.
Line-Level In L/R Connectors: Use these connectors if your receiver
or preamp/processor does not have digital surround-sound decoding
or a low-pass-filtered subwoofer output.
• 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 the receiver or preamp/processor’s
subwoofer output to either one of the subwoofer’s Line-Level In L/R
connectors.
• If your receiver or preamp/processor does not have a separate
subwoofer output, use two Y-adapters (not supplied). Connect one
adapter’s single end to the unit’s preamp output for that channel.
Connect one of this adapter’s dual ends to the main amp input for
that channel, and connect the adapter’s other dual end to one of the
subwoofer’s Line-Level In L/R Connectors. Repeat this process with
the other Y-adapter, the preamp channel, the main amp input and the
subwoofer’s other Line-Level In L/R connector.
Power Switch: Set this switch in the On position to turn the subwoofer
on. The subwoofer will then either be on or in Standby mode, depend-
ing on the setting of the subwoofer’s Power On Mode switch.
AC Power Cord: After you have made and verified all subwoofer and
speaker connections described in this manual, plug the Power Cord into
an active, unswitched electrical outlet (that is, an outlet not connected
to a light switch) for proper operation of the subwoofer. DO NOT plug
this cord into the accessory outlets found in some audio components.
