The Harman Kardon company makes a range of audio equipment for use with your personal computer or home theatre system. The Harman Kardon Soundsticks II is a simple speaker system that features two satellite speakers as well as a subwoofer to give you deeper sound for your music and movies. If you are having issues operating your Soundsticks II system, you can diagnose the problems on your own by following a few troubleshooting steps.
If you are not receiving power to the system when you press the "Power" button, check the power supply and ensure that it is properly connected to a wall outlet as well as to the input on the back of the subwoofer unit. You will see a green LED light turn on if the power cord is connected properly. If it is connected properly and you still are not getting power, your unit may be defective.
After your system is powered on, press the + and -- buttons together to unmute it, then slowly press the + button on the right speaker of the unit to increase the volume if you are not hearing sound from the system. If still don't hear sound, the system may not be set up properly.
Check the connections from the satellite speakers to the subwoofer unit. The cords from these units should be plugged into the "Out" jacks labelled "Left" and "Right" on the back of the subwoofer. The input device, such as your computer or home entertainment device, should be connected to the "In" jacks located on the back of the subwoofer.
Adjust the "Vol" knob on the back of the subwoofer if you are hearing sound from the speakers but not the subwoofer. The subwoofer has its own separate volume control, which you will need to adjust accordingly. If you have turned the subwoofer volume up but are still not hearing sound from the subwoofer, it may be defective.
Turn the speakers toward you and angle them so that the speakers are facing straight forward if your music sounds flat or distorted. The speakers in this system are directional speakers, meaning that they will not sound right if the are facing away from the listener.
