[. . . ] In discrete channel digital processors these modes are referred to as "small" and "large. " Normal (small) mode filters bass frequencies from the center channel speaker and sends them instead to the front left & right main speakers or to the subwoofer output (LFE) jack. wide (large) mode sends an unfiltered , full range signal to the center channel speaker. Use the Small (normal) mode for optimum center (and surround) channel performance and reliability. [. . . ] Make certain that you connect the wire from the red (+) terminal of your amplifier or receiver to the red (+) terminal on your speaker and the wire from the black (-) terminal of your amplifier or receiver to the black (-) terminal on your speaker. Most wire has some indicator (such as color-coding, ribbing or writing) on one of the two conductors to help you maintain consistency. To connect wire to the binding post [figure 7], unscrew the hex nut and insert the bare wire into the hole near the base of the binding post. Do not insert the insulated part of the wire into the hole as this will not give you a good connection. Twist the hex nut back down the binding post until it firmly meets the wire. To use Banana Plugs (US only): Unscrew the binding post lug nuts completely to expose the binding post plugs (plastic plugs inserted into the binding posts). Carefully pry out the binding post plugs to expose banana plug holes. Screw the lug nuts back on the binding posts and insert banana plugs. If you decide to bi-wire or bi-amp, you must remove the flat metal jumpers between terminal posts. Failure to do this could result in damage to your amplifier and loudspeakers. Bi-wiring [figure 8] can provide noticeable improvements in the overall transparency of your loudspeakers. Your Polk loudspeakers are made with the highest quality materials for years of troublefree performance. However, damage to loudspeakers can occur when an amplifier, regardless of its wattage, is made to play at higher listening levels than its power can clearly produce (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, that can add a harsh, gritty sound to music. 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. Line up the keyhole slots on the back of the speakers so that the screw heads pass through the large center hole of the slots. â· Let the speaker and slide straight down, allowing the screw head to slip behind the smaller end of the keyhole slot [figure 12]. â· Tug gently on the speaker to make certain that the screws and bracket are properly aligned and that the wall anchors are secure. â· If the bracket is not held snug against the wall by the screw heads, remove the speaker from the wall, drive the screws in a little further and then remount the speaker. Your new Loudspeakers are constructed of a rugged material that can be dusted or cleaned with a damp cloth. Avoid harsh detergents and cleaning fluids, as they can permanently damage your speakers' finish [figure 13]. Bi-amping, or using separate amplifiers for the low and high frequency sections of your speakers.
