Question about Boston Acoustics BA745 Computer Speakers
1) Try the portable player test. Unplug the speakers from the computer
and plug them into the headphone output of a portable-type stereo
product. This test should produce sound. If it does the problem is most
likely in the soundcard, or in your internal volume settings. You should
contact your computer's support group for further help in those areas.
2) Is the green power light illuminated? If not, you could have one of two possible causes. The first and less serious issue is that the power supply is not outputting the correct voltage. You can test the power supply with a voltage meter or you can always take the power supply to any electronics store and have it checked there. If it is not outputting the correct voltage (12VAC), contact our parts department for a new one at (978) 538-5136.
If the power supply is working properly, then your problem is most likely in the amplifier. In this case, we will need to fix your system here, and you can contact customer service at the above phone number to set this up.
3) If the system is connected properly and you have a green subwoofer light, disconnect the power supply from the wall for 10 minutes. This is a common problem on overloaded surge protectors. To many devices on the same surge protector can limit available power. Putting your speaker system on its own circuit (or a more dedicated one) should eliminate this problem.
4) Check the bass level on the back of your subwoofer, (or on your desktop control pod. For best subwoofer performance place the woofer on the floor along a wall or better still in a corner. This "corner loading" will increase bass output.
