Unpacking Your CS8040HD

Please Inspect For Shipping Damage

Each loudspeaker leaves our plant in perfect condition. Any visible or concealed damage most likely occurred in handling after it left our plant and should be reported at once to your Definitive dealer or the delivery company that delivered your loudspeaker. Please unpack your system carefully. Save all cartons and packing materials in case you move or need to ship your system. Record the serial number found on the back of the Center Channel in the Notes section of this owner's manual.

Positioning Your Speakers

Your new CS Series speaker is designed to add clarity and focus to the vocal range and extend the musical image of your home theater. To optimize its performance, please follow these simple guidelines. Although the following recommendations will usually yield the best results, whatever sounds best to you is correct.

To receive the full benefit of the bass radiators built into your CS Speaker leave at least 1-2" (2.5-5 cm) of space between the top of the speaker and any surface.

ACenter Channel Speaker should be placed as close to the center of your television as possible with- out obstructing your view.

All Dolby/DTS multi-channel receiver/amplifiers feature a dedicated channel for a center speaker. Consult your receiver's owner's manual for the appropriate connection procedure.

Troubleshooting

If you experience any difficulties with your CS Series Speaker, try the suggestions below. If you still have problems, contact your Definitive Technology Authorized Dealer for assistance.

1. Audible distortion when the speakers are playing at loud levels is caused

by driving (turning up) your receiver or amplifier louder than the receiver or

the speakers are capable of playing. Most receivers and amplifiers put out

their full-rated power well before the volume control is turned all the way

up, so the position of the volume control is a poor indicator of its power

limit. If your speakers distort when you play them loud, turn the

volume down!

2. If you experience a lack of bass, it is likely that one speaker is out of phase

(polarity) with the other speakers in the system and needs to be rewired

paying closer attention to connect positive to positive; negative to negative

on both channels. Most speaker wire has some indicator (such as color-

coding, ribbing or writing) on one of the two conductors to help you main-

tain consistency. It is essential to connect both speakers to the amplifier in

Strip 1/4" (6mm) wire.
