MAINTAINING THE APPEARANCE OF YOUR PSW1200

Your new speaker cabinet is finished in woodgrain vinyl that can be dusted or cleaned with a moist soft cloth. Avoid harsh detergents and cleaning fluids, they can permanently damage your speaker’s finish. Remove grilles and gently vacuum the dust.

Q.“WHY DOES MY SYSTEM HUM?”

A.“It doesn’t know the words.”

This is what passes for humor in the audio business. Here is the real answer:

If you have any electrical 60Hz hum in your system, you are more likely to hear it once you hook up your Subwoofer. Most hum problems are caused by ground loops. That is, the electrical grounds of the components in your system are not at the same electri- cal potential. A very common ground loop source is cable TV. Disconnect the coaxial cable from your TV and/or VCR. If the hum goes away, the cable is the ground loop villain. In that case, you need a 75-ohm ground loop isolator. This device is about the size of a pen and is attached to your coaxial cable where it plugs into your VCR (or televi- sion). You can obtain this device from some audio dealers, Radio Shack stores,

Zantech (1-800-843-5465) or Channel Plus (1-800-99-5225).

Ground loops and hum can also be the result of faulty electrical wiring in your home. Consult a licensed electrician to evaluate and, if necessary, repair the AC wiring in your home. Light dimmers also tend to introduce noise into audio systems. Remove them.
