May 2000 Vol.6 Issue 5 Page(s) 22 - 25 in print issue Add To My Personal Library Adjust Your Video Card, Sound Card & Speakers To Maximize Your Multimedia Experience Speakers are a vital component in creating rich, multimedia audio on your computer, but they can cause some problems. Without the correct shielding, speakers will cause interference, which usually shows itself as a rolling, wavering picture on the monitor. The first step toward reducing interference is using speakers designed for a computer. Speakers designed for a stereo aren't magnetically shielded, meaning they could emanate magnetic interference. Stereo speakers can't adequately reproduce the signal coming from a sound card, either, because sound card signals are weak when compared to audio signals created in a stereo. Keep in mind that most subwoofers aren't magnetically shielded, regardless of whether they're made to work with a computer. That's because a subwoofer is designed to be stored a few feet away from the monitor, where it shouldn't cause interference. Poorly manufactured computer
Products & Services
Audio cables transmit audible signals such as voice and music. They are designed to minimize noise and interference that can impair sound quality. Audio cables connect an audio source such as a stereo or microphone to an audio receiver or output such as speakers. Most products are shielded to prevent electromagnetic interference (EMI), typically with a foil and/or braided shield.
Speakers produce and transmit sounds carried by electrical or radio signals. This product category is primarily for industrial and OEM speakers rather than those for home use.
Audio Switch Matrices
Audio switch matrices are electronic switching instruments for interfacing audio signals in scanning, recording and analysis systems.
Sound cards are computer expansion cards that enable audio inputs and outputs. They connect to the computer via the internal bus or an external connection.
Audio headphones are small speakers worn over the ears to isolate sounds for the listener.
