Polk Audio’s mission has always been to build high quality, great sounding speakers at affordable prices. For the people of Polk Audio, building speakers is not just a job; it’s a passion.

SAFE LIMITS OF

OPERATION

Your Polk loudspeak- ers are made with the highest quality materi- als for years of trou- ble-free performance. However, damage to loudspeakers can occur when an ampli- fier, 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 con- trol). 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 try- ing to get too much volume from a low- powered amp or receiver than from a high powered one.

PLACEMENT RECOMMENDATIONS

FOR THE CSM SERIES CENTER CHANNEL LOUDSPEAKER

The CSM Series Center Channel Loudspeaker incorporates the most effective magnetic shielding available so it can be placed safely on or near your TV or video monitor. If you notice video distortion or discoloration, immediately move the speaker away from the TV and call Polk Audio Customer Service 800-377-7655 (9AM to 6PM EST, US or Canada) or polkcs@polkaudio.com. The most popular placement for a center channel speaker is on top of your TV, anchoring the dialogue and effects to the screen [figure 1]. An alternate placement is on a shelf below your TV [figure 1]. If you are using a front projection TV system, place the center channel speaker on a small stand or table immediately below the bottom of the projection screen, or at ear level behind the screen if your screen is acoustically transparent. Consult the owner’s manual for your screen. Adhesive rubber feet are included with your CSM Center Channel Loudspeaker and may be attached to the bottom of the speaker to protect your furniture and keep the speaker in place.

PROCESSOR MODE CONFIGURATION

FOR THE CSM SERIES CENTER CHANNEL LOUDSPEAKER

The “bass management” or “speaker configuration” menus of most surround receivers offer the choice of “normal” or “wide” modes for center channel operation. 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.

CONNECTING YOUR CSM SERIES LOUDSPEAKER [FIGURE 2]

We recommend 16-gauge or larger speaker wire. Follow the hookup directions included with your receiver. Strip 1/2 inch (12.7mm) of insulation from each of the two conductors of the wire to expose the bare metal and twist each of the individual conductors into single unfrayed strands. Note that one of the terminals on the rear of each speaker is red (+) and the other is black (-). 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 3], 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. Do not over tighten.

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. (This is for US owners only.)
