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. 9 Amplifier/SubwooferHarman Kardon SUB-TS1 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. 10 Amplifier/SubwooferHarman Kardon SUB-TS1 HKTS1 PACKING HKTS1 OWNERS MANUAL #AI5058 FEET/PADS #WI5162 (10) WARRANTY CARD #AT5073 PLASTIC BAG OUTER CARTON #WB5452 SUBWOOFER FOAM SET #WB5078 SATELLITE FOAM SET #WP5071 SUB-TS1 SUBWOOFER OPTIONAL SAT-TS1 SPEAKER STANDS: FSTS1 WALL HOOKS #WI0408 (5) MURAL STANDS #WI0409 (5) HKTS1 HKTS1 SATELLITE SPEAKERS SAT-TS1 (5) #HKTS1/SAT ACCESSORY WIRES PART NUMBER SAL5010 SAL063-1 SAL5009 DESCRIPTION Right, Left &Center cables (1 pack, 3 pairs) High level input cables (3 pack, 1pair each) Surround cables (2 pack, 1 pair each) 11 Amplifier/SubwooferHarman Kardon SUB-TS1 SUB-TS1 EXPLODED VIEW 25 27 41 25 26 24 24 21 22 23 17 14 14 8 11 10 12 36 2 3535 32 31 31 3235 9 38 28 28 16 29 24 18 18 13 29 28 11 13 11 28 386 5 4 28 38 28 28 28 28 15 38 29 3 7 19 20 42 44 43 34 40 39 VIEWING CABINET BOTTOM HGFEDCBA ABC LMKJI FGHDELMIJK DESCRIPTIONPART NUMBER #3PLASTIC KNOB700KB800 #4POWER SWITCH180PBR12C11S #5FUSE HOLDER15552001 #6POWER CORD 120V152U602015 #8POWER TRANSFORMER150E8604104 #11AMPLIFIER PLATE640RP125-4 #15SLIDE SWITCH AUTO-ON180SMS50126 #21FULLY LOADED MAIN PCB1010SUB125A #22MICAINSULATOR1933M2520 #34HARMAN KARDON LOGOSZ5162 #36PORT TUBE700PT125 #408 WOOFER20MF10DJ-DW04 #41SPEAKER TERMINALS1742-CJ9030 #42AMPLIFIER ASSEMBLY106HKTS1-1 #43GRILLEXC085000 #44GRILLE CUPS (RETAINERS)WI5192 Ref.
