In most cases, this switch should be set to “0.” If you have hooked up the subwoofers from a subwoofer output or pre-out jacks and cannot get enough bass output even with the subwoofer level control turned all the way up, switch to the +3dB position. In typical systems where the 3dB boost is not needed, this switch can be useful for providing a quick boost for bass-shy program material. Most people prefer more bass output for movies than music so you can use this switch as a handy way to adjust bass levels as you switch between movie and music sources.

Q . “ W H Y D O E S M Y S Y S T E M H U M ? ”

BECAUSE IT DOESN'T KNOW THE WORDS.

This is what passes for humor in the audio business. Here’s the real answer: If you have any electrical (50/60Hz) hum in your system you’re going to hear it clearly as soon as 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 electrical 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 attaches to your coaxial cable where it plugs into your VCR (or television). They’re simple to install and usually solve the hum problem. Find 75 ohm ground loop isolators at your audio dealer, Radio Shack stores, or online at http://polkaudio.tranguard.com/.

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.

Your Polk Audio loudspeakers are made with the highest-quality materials to ensure years of great sounding, trouble-free performance. However, damage to loudspeakers can occur when an amplifier, regardless of its wattage, is made to play at higher listening levels that its power can clear- ly produce. (This is usually beyond the “1 to 2 o’clock” position on the volume control.) This results in very high levels of audible distortion originating in the amplifier, which adds a harsh, gritty sound to the music you’re listening to. Contrary to popular belief, a speaker is more likely to be damaged by trying to get too much volume from a low-powered amp or receiver (than from a high-powered one).

Your new RM7000 Series Loudspeakers are finished in rugged vinyl. Avoid harsh detergents and cleaning fluids, as they can permanently damage your speakers’ finish (Figure 16). Instead, clean the speaker cabinets with non-abrasive products like Windex or Brillianize Brand products and a clean soft cloth. Gently vacuum the grilles to remove dust.
