Introduction

Thank you for purchasing the Harman Kardon?? HKTS 18, with which you???re about to begin many years of listening enjoyment. The HKTS 18 has been custom-designed to provide all the excitement and power of the cinema experience in your own living room. To obtain maximum enjoyment from your new home theater speaker system, we urge you to take a few minutes to read through this manual. This will ensure that connec- tions to your receiver or preamp/processor and amplifier or other external devices are made properly. In addition, a few minutes spent learning the functions of the controls will enhance the HKTS 18???s performance.

If you have any questions about this prod- uct, its installation or its operation, please contact your dealer, the best local source of information, or visit our Web site at www.harmankardon.com.

Description and Features

The HKTS 18 is a six-piece home theater speaker system that includes a 10-inch, 200-watt, bass-reflex powered subwoofer; four identical, two-way, dual-midrange satellite speakers for use in the left and right front and rear speaker positions; a voice-matched, dedicated, dual-driver center speaker; shelf stands and wall-mount brackets for the four satellites; and all of the speaker cables you need to connect your speakers to your receiver or preamp/ processor and amplifier. The speaker cables and speakers are all color-coded to con- form to the CEA?? standard, simplifying setup, especially when the system is used with a Harman Kardon receiver.

The HKTS 18 subwoofer is easy to connect to your system, since it???s equipped with a subwoofer input for use with equipment that has a dedicated subwoofer low-frequency output. It also includes stereo speaker-level inputs and outputs for connection to older receivers and processors that do not have a line-level subwoofer output. Other conve-

niences include a level control, an external trigger input for automatic turn-on when connected to a compatible product, a high- cut (low-pass) filter switch and a phase switch for fine-tuning bass response to suit your listening environment and taste, and audio-sense auto turn-on, which senses the presence of an audio signal and automati- cally switches the unit from Standby mode to Active mode.

Shelf stands and wall-mount brackets are included for the satellite speakers, and optional HTFS 2 floor stands are available separately from your Harman Kardon dealer. Harman Kardon invented the high-fidelity receiver more than fifty years ago. With state-of-the-art features and time-honored circuit designs, the HKTS 18 is a perfect complement to a Harman Kardon receiver or any home theater system.

?? Subwoofer-Level Control: Volume may be adjusted using the Subwoofer- Level Control. Turn the control clockwise to increase the SUB-TS18???s volume, or counterclockwise to decrease it.

??? High-Cut (Low-Pass) Filter Switch:

Placing this switch in the ON position acti- vates circuitry that cuts out all audio input signals above 120Hz, allowing the SUB-TS18 to focus its power on reproducing the low- frequency portion of the signal, avoiding

inefficiency and distortion. Engage this filter when using the Speaker-Level Inputs ??, or when using the Line-Level Full-Range Inputs ??, unless your receiver or processor processes its line-level output using a low- pass filter. The filter has no effect when the

SUB Input ?? is used.

?? External Trigger Input: Use the sup- plied mini-plug cable to connect the trigger output of another product to this jack. When a trigger signal between 3 and 30 volts (AC

or DC) is detected, the SUB-TS18 amplifier will turn on, even when the audio-sense feature has been activated by placing the

Audio-Sense On/Off Switch ?? in the

AUTO position. The amplifier will remain on for about 10 ???15 minutes without a trigger signal.

?? Audio-Sense On/Off Switch: When placed in the AUTO position, and when the

Master Power Switch ???is turned on, the SUB-TS18 will automatically turn itself on or

place itself in the Standby mode, depending on whether it is receiving an audio signal. When this switch is placed in the ON position, the SUB-TS18 will remain on, whether or not it is receiving an audio signal.

An LED located on top of the SUB-TS18 indicates whether the SUB-TS18 is in the On or Standby state when used with the Audio- Sense On/Off Switch ?? in the AUTO position. The LED is lit blue to indicate that the SUB-TS18 is receiving an audio signal and is turned on, and the LED is lit amber to indicate that no signal is being received and the SUB-TS18 is in the Standby mode.

When the Audio-Sense On/Off Switch ?? is in the ON position, the LED will be lit blue, whether or not an audio signal is present.

When the Master Power Switch ??? is turned off, the LED goes dark, no matter which position the Audio-Sense On/Off Switch ?? is in.

??? Phase Switch: This switch determines whether the SUB-TS18 subwoofer???s piston- like action moves in and out in phase with the main speakers. If the speakers were to play out of phase, the sound waves pro- duced by the subwoofer would be canceled out, reducing bass response. This phenome- non depends in part on the relative place- ment of 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 with the Phase Switch ???, and you may leave it in the position that maximizes bass response.

?? Line-Level Subwoofer (SUB) Input:

Connect the subwoofer output of a receiver with digital surround sound decoding, such as Dolby?? Digital or DTS??, to this input. This input bypasses the SUB-TS18???s internal crossover circuitry, and should only be used with a filtered signal. If your receiver does not have digital decoding, you should use the

Line-Level Full-Range Inputs ?? instead.

?? Line-Level Full-Range Inputs: Connect the line-level subwoofer output or preamp out- put(s) of your receiver or amplifier to these inputs. If your receiver does not have a sepa- rate subwoofer output, use a Y-adapter (not supplied) to bridge the receiver???s preamp out- put to the main amp input for that channel, and connect the long end of the adapter

to the corresponding line-level input on the SUB-TS18. If your receiver has only a single subwoofer output, you may connect it to either the left or right line-level input on the SUB-TS 18, and no Y-adapter is needed.

???Speaker-Level Outputs: If you are using the Speaker-Level Inputs ?? on the SUB-TS18, you should connect these binding- post terminals to your front left and right speakers, remembering to maintain polarity by connecting the (+) terminal on the SUB-TS18 subwoofer to the (+) terminal

on the speaker, and the (???) terminal on the SUB-TS18 subwoofer to the (???) terminal on the speaker. If you are not using the

Speaker-Level Inputs ??, then connect your front left and right speakers directly to your receiver or amplifier. See pages 9

through 12 for further information on speaker connections.

?? Speaker-Level Inputs: If your receiver or amplifier does not have a line-level sub- woofer output, connect these binding-post terminals to the main left and right speaker terminals of your receiver or amplifier. Remember to maintain polarity by connecting the (+) terminal on the receiver/amplifier to the

(+) terminal on the SUB-TS18 subwoofer, and the (???) terminal on the receiver/amplifier to the

(???) terminal on the SUB-TS18 subwoofer.

???Master Power Switch: Place this switch in the ????????? position to power-on the SUB-TS18 subwoofer. The SUB-TS18 will then be either in the Standby mode or com- pletely on, depending on the position of the

Audio-Sense On/Off Switch ??.

???AC Power Cord: Make sure to plug this cord into an active, unswitched electrical out- let for proper operation of the SUB-TS18.

The cord should not be plugged into the accessory outlets found on some audio components.

Color-Coding System

The HKTS 18 uses the channel color-cod- ing system established by the Consumer Electronics Association to make setting up your home theater speaker system as easy as possible. Your system includes a set of colored stickers that may be placed near the speaker terminals of each of the four satellite speakers according to the chart below. It doesn???t matter which satellite speaker is used for any of the front or rear positions. (The center speaker and powered subwoofer are already color-coded for you.)

Video Screen

Center Speaker

Before you begin to connect cables, it is important to set up your speakers in their correct locations in the room.

Optimally, the speakers should be placed in a circle with the listening position at its cen- ter. The distance from the listening position to the video display forms the radius of

the circle.

The speakers should be angled so that they directly face the listening position. The cen- ter speaker is placed either on top of or below the video display screen.

The front left and right speakers are placed along the circle, about 30 degrees from the center speaker and angled toward

the listener.

It is best to place the front left/right and center speakers as close to the same height as possible, preferably about the same height as the listener???s ears. In any event, the center speaker should be no more than two feet above or below the left/right speakers.

The side surround speakers should be placed 110 degrees from the center speaker; that is, slightly behind and angled toward the listener. If this isn???t feasible, place the surround speakers behind the listener, with each surround speaker facing the opposite-side front speaker. The surround speakers may be placed a little higher than the listener???s ears.

The subwoofer???s location is less critical, since low-frequency sounds are omni- directional. Placing the subwoofer close to a wall or in a corner will reinforce the low fre- quencies, and may create a ???boomy??? sound. You may wish to experiment over time by placing the subwoofer where the listener normally sits and then walking around the room until the low frequencies sound best. Place the subwoofer in that spot.

Satellites and Surrounds

The satellite speakers may be placed on a shelf. Place each satel- lite speaker on one of the supplied coasters for added stability and to protect your furniture.

The satellite speakers may be wall-mounted using the supplied brackets.

Wall-Mounting

Unscrew the bolt that attaches the black shelf stand to the bottom of the speaker. Store the stand and bolt in a safe place, in case they are needed for a future installation.

Wall Plate

Mount the wall- bracket attachment plate on the wall in

the desired loca- tion. If possible,

position the

speakers so that the mounting screws (not included; use size #8) may be installed directly into a wooden wall stud. If that is not possible, use optional wall anchors that are rated to support at least 25 pounds. The customer is responsible for proper selection and use of mounting hard- ware, available through hardware stores, to properly and safely wall-mount the speakers.

Referring to the speaker connection instruc- tions on pages 9 through 12, thread the appropriate speaker cable through the open- ing in the bottom of the wall plate, and then through the back of the bracket, as shown in the diagram above. The bracket has two

Wires to Speaker

Terminal Cover

openings on top: a round screw hole, and an arc-shaped opening in front of it. The speaker cable should be threaded through the arc- shaped opening, not the screw hole.

Attach the bracket to the wall plate by inserting the tab at the top of the wall plate into the slot on top of the bracket and snapping the bracket onto the wall plate.

Thread the cable through the round opening in the terminal cover, and then insert the speaker wires into the terminals on the underside of the speaker, remembering to observe the correct polarity (see page 9). Place the terminal cover over the opening on the underside of the speaker so that it fits flush against the speaker and covers the terminals, with its round opening exposing the threaded insert. The bracket fits through the round opening in the terminal cover.

Wall Plate

Insert the supplied bracket bolt up through the bottom of the bracket and terminal cover, and screw it into the threaded insert on the underside of the speaker. The bolt should be snug, but not so tight as to prevent the bracket from pivoting.

The wall-mounted speaker may be pivoted from side to side; however, the bracket is not designed to be tilted up or down, and attempting to tilt it will damage the bracket and possibly the wall, which would not be covered by your warranty.

Speaker-Level Connection Guide

IMPORTANT NOTE: Before making speaker connections, be certain that your receiver or audio power amplifier is turned off and preferably unplugged from its AC power source. The SUB-TS18 subwoofer should not be connected to an AC power source until all speaker wire connections have been made.

Speakers and electronics terminals have corresponding (+) and (???) terminals. Most manufacturers of speakers and electronics, including Harman Kardon, use red to denote the (+) terminal and black for the (???) terminal.

Newer Harman Kardon receivers conform to the new CEA standard and therefore use a color other than red or black for the (+) ter- minal to indicate some speaker positions: e.g., surround left. Although the HKTS 18 system has red and black collars on the individual speaker terminals to denote the positive and negative connections, your system includes a colored band on the positive lead at both ends of every speaker cable and a matching colored sticker for each of the four satellite speakers, conforming to the chart on page 7. The center speaker has a green (+) terminal, and the subwoofer

has a purple SUB input jack. This system is intended to help you ensure that the speaker in each location is connected to the correct terminals on your receiver or amplifier.

The (+) lead of the speaker wire is indicated with a stripe and has the colored band cor- responding to the speaker???s position. It is important to connect all speakers identically:

(+) on the speaker to (+) on the amplifier and (???) on the speaker to (???) on the ampli- fier. Wiring ???out of phase??? results in thin sound, weak bass and a poor stereo image.

With the advent of multichannel surround sound systems, connecting all of the speakers in your system with the correct polarity remains equally important in order to preserve the proper ambience and directionality of the program material.

To connect the supplied speaker wires to the satellite and center speaker terminals located on the bottom of each speaker, press the red or black tab, insert the bare end of the wire into the hole and release the tab. Gently tug on the wire to make sure that it is fully inserted.

For the best performance, Harman Kardon recommends that the subwoofer be con- nected using either the Line-Level Subwoofer (SUB) Input ?? or the Line- Level Full-Range Inputs ??. However, if the application requires the use of the speaker-level connections for the subwoofer, unscrew the binding-post collar until the pass-through hole in the center post is visi- ble under the collar. Insert the bare end of the wire through this hole; then screw the collar down until the connection is tight. The hole in the center of each collar is intended for use with banana-type connectors.

Move the Master Power Switch ???

(marked Power) to the ????????? (On) position. The SUB-TS18 subwoofer will automatically turn itself on or go into Standby mode, depending on whether or not a signal is being sent to it by your receiver or surround processor, and provided that the Audio- Sense On/Off Switch ?? is moved down so that it is in the AUTO position.

When your receiver or amplifier is off, or is not sending program material to the sub- woofer, the subwoofer will be in Standby mode and the LED indicator on the top

of the subwoofer will turn amber. When the subwoofer senses an audio signal, it will auto- matically turn itself on and the LED indicator will turn blue. If the subwoofer does not sense a signal after approximately 20 minutes, it will automatically go into Standby mode.

When the Audio-Sense On/Off Switch ?? is switched to the ON position, the sub- woofer will remain on, whether or not pro- gram material is playing, and the LED indica- tor will remain lit blue.

If your receiver, processor or amplifier is equipped with a compatible trigger output, you may connect it to the SUB-TS18???s

External Trigger Input ??. When you turn on your component, if you have set it up cor- rectly, it will send an electrical trigger signal to the SUB-TS18, which will cause the subwoofer to turn itself on, even when the

Audio-Sense On/Off Switch ?? has been placed in the AUTO position and no audio signal is detected.

The trigger signal must be between 3 and 30 volts, although it may be an AC or DC signal, and an AC signal may be 50Hz or 60Hz.

If you???ll be away from home for an extended period of time, or if the subwoofer will not be used, switch the Master Power Switch ??? to the OFF position.

Additional Bass Adjustments

In addition to the volume adjustments described previously, the SUB-TS18 subwoofer includes a Phase Switch ??? and a Filter Switch

??? that can be used to adjust the bass response to suit your listening environment or taste.

In most situations, the Phase Switch ??? should be left in the NORMAL position. If you suspect that the subwoofer is playing out of phase with the other speakers, which would tend to diminish bass response, try placing this switch in the REVERSE position. There is no harm in experimenting, and you may return the switch to the NORMAL position at any time. If you rearrange your room and reposition the speakers, it would be a good idea to check whether they are in phase by flipping this switch.

The High-Cut (Low-Pass) Filter Switch

??? limits the frequencies of the audio signal inputted to the subwoofer to the low fre- quencies that the subwoofer reproduces best. This allows the subwoofer to perform more efficiently, and with superior bass reproduction, minimizing distortion that might occur if the subwoofer attempted to repro- duce higher frequencies. This switch should be left in the ON position, except:

1.When the SUB Input ?? is being used, in which case it has no effect, or

2.When the Speaker-Level Inputs ?? or the Line-Level Full-Range Inputs

?? are being used with a crossover or filter aboard the receiver or processor.

In these two circumstances, place the switch in the OFF position.

If there is no sound from any of the speakers:

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

???Check that the powered subwoofer is plugged in and its Master Power Switch ??? is switched on to the ????????? position.

???Check all wires and connections between receiver/amplifier and speakers. Make sure all wires are connected. Make sure none of the speaker wires are frayed, cut, punctured or touching other wires.

???Review proper operation of your receiver/amplifier.
