Amplifier/Subwoofer Harman Kardon

SUB-TS1

1. Speaker Level Outputs - Connect the Left, Center

and Right speakers to these connectors.

2. Speaker Level Inputs - These High Level Inputs are

for receivers that do not have line-level “pre-amp out”

or “subwoofer out” jacks. When a pair of main or

satellite speakers are attached to the OUTPUT

terminals, they are driven the full range of frequencies

as generated by the music source (receiver, amplifier,

etc.)

3. Line Level Input - These left and right Line Level

Inputs are normally used when the receiver/ processor

has line-level “pre-amp out ” or “subwoofer out” jacks.

4. Auto/On Switch - This switch allows you to set the

Mode of the Amplifier. Turn the switch to Auto to

cause it to Auto-matically turn on when it receives a

signal and Auto-matically turn off after twenty minutes

without a signal. If this switch is left “On”, the

subwoofer will always be ON when the power switch

is turned On, regardless of input signal.

5. Subwoofer Level - This knob controls the volume

level of the SUB125.

6. LED - Red & Green. The LEDs indicate the Mode

status that the subwoofer is in. When the SUB125 is

turned OFF neither LED will be lit. The Green LED

will light when the SUB125 is ON and receiving a

signal. The Red LED will light when the amplifier has

not received a signal for twenty minutes. The

subwoofer will turn on when your receiver/amplifier

begins playing again.

7. Power Switch - This the master power switch. Use it

(in Off mode) to disconnect power to the amplifier.

8. Fuse - Use only same type of fuses. For the U.S.

120V version use only a 2A 250V fuse. For the

European 230V version use only a 1A fuse.

General Function

UUT = Unit Under Test

1. Connect both right and left line level inputs (RCA) to

signal generator and UUT. Use Y-cable if necessary

from mono source. VOLUME control should be full

counterclockwise.

2. Turn on generator, adjust to 200mV, 50 Hz.

3. Plug in UUT; red LED should be ON. Turn VOLUME

control full clockwise.

4. LED should turn Green; immediate bass response should

be heard and felt from port tube opening.

5. Turn off generator, turn VOLUME control fully

counterclockwise, disconnect RCA cables.

6. Connect one pair of speaker cables to both high level

input terminals on UUT. Cables should be connected to

an integrated amplifier fed by the signal generator.

7. Turn on generator and adjust so that speaker level output is 3.0V, 50 Hz. Turn VOLUME control full clockwise.

8. Green LED should light, immediate bass response should be heard and felt from the port tube opening.

Sweep Function

1. Follow steps 1-4 above, using a sweep generator as a signal source.

2. Sweep generator from 20Hz to 300Hz. Listen to the cabinet and drivers for any rattles, clicks, buzzes or any

other noises. If any unusual noises are heard, remove driver and test.

Driver Function

1. Remove driver from cabinet; detach + and - wire clips.

2. Check DC resistance of driver; it should be 3.3 ohms.

3. Connect a pair of speaker cables to driver terminals. Cables should be connected to an integrated amplifier fed by

a signal generator. Turn on generator and adjust so that speaker level output is 5.0V.

4. Sweep generator from 20Hz to 1kHz. Listen to driver for any rubbing, buzzing, or other unusual noises.

SIMPLE TROUBLESHOOTING

If there is no sound from any of the

speakers, check the following:

•Receiver/amplifier is on and a source is playing.

•Powered subwoofer is plugged in and is either in the “On”

or “Auto”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 or

punctured.

•Review proper operation of your receiver/amplifier. If there

is no sound coming from one speaker, check the following:

•Check the “Balance”control on your receiver/amplifier.

If the system plays at low volumes but

shuts off as volume is increased, check the

following:

•Check all wires and con-nections between receiver/

amplifier and speakers. Make sure all wires are connected.

Make sure none of the speaker wires are frayed, cut or

punctured.

•If more than one pair of main speakers is being used,

check the minimum impedance requirements of your

receiver/amplifier.

If there is low bass output, check the

following:

•Make sure the connections to the left and right “Speaker

Inputs”have the correct polarity (+ and –).

•Powered subwoofer is plugged in and is either in the “On”

or “Auto”position.

If there is no sound from the surround

speakers, check the following:

•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 or

punctured.

•Review proper operation of your receiver/amplifier and its

surround sound features.

•Receiver mode must be in Dolby Pro logic, Dolby Digital,

or any other mode that creates a surround-sound effect.

Even under normal operation, when viewing movies and

television, surround sound is not present at all times at a

high volume - only when the program has chosen to send

information there.
