Basic Installation

The JBL Cinema Vision system offers a vari- ety of entertainment options, including play- back of DVDs and CDs, and radio listening, and it may be enjoyed with no additional equipment. However, it is also compatible with most available audio/video devices.

IMPORTANT NOTE: For your personal safety and to avoid possible damage to your equipment and speakers, it is always a good practice to turn off and unplug the CVR700, CVPD50 and ALL source equipment from AC power before making any audio or video system con- nections.

Step One: Connect the Front, Center, Surround and Surround Back Speaker Outputs ¡™£¢ to the respective

speakers.

To ensure that all the audio signals are carried to your speakers without loss of clarity or resolution, we suggest that you use high-quality speaker cable. Many brands of cable are available and the choice of cable may be influenced by the distance between your speakers and the receiver, the type of speakers you use, per- sonal preferences and other factors. Your dealer or installer is a valuable resource to consult in selecting the proper cable. Regardless of the brand of cable selected, we recommend that you use a cable con- structed of multistrand copper with a gauge of 14 or smaller. Remember that in specifying cable, the lower the number, the thicker the cable. Cable with a gauge of 16 may be used for short runs of less than 3 meters (10 feet). We do not recom- mend that you use cables with an AWG equivalent of 18 or higher, due to the power loss and degradation in perform- ance that will occur. Cables that are run inside walls should have the appropriate markings to indicate listing with UL, CSA or other appropriate testing agency stan- dards. Questions about running cables inside walls should be referred to your installer or a licensed electrician who is familiar with the NEC and/or the applica- ble local building codes in your area.

When connecting wires to the speakers, be certain to observe proper polarity. Note that the positive (+) terminal of each speaker connection now carries a specific color code, as noted on page 20. How- ever, most speakers still use a red terminal for the positive (+) connection. Connect the “negative” or “black” wire to the same terminal on both the receiver and the speaker.

NOTE: While most speaker manufactur- ers adhere to an industry convention of using black terminals for negative and red ones for positive, some may vary from this configuration. To ensure proper phase and optimal performance, consult the identification plate on your speaker or the speaker’s manual to verify polarity. If you do not know the polarity of your speaker, ask your dealer for advice before proceeding, or consult the manufacturer. We also recommend that the length of cable used to connect speaker pairs be identical. For example, use the same length piece of cable to connect the front-left and front-right or surround-left and surround-right speakers, even if the speakers are a different distance from the CVR700.

It is appropriate to configure the CVR700 for either 5.1- or 7.1-channel operation, but not for 6.1 channels. When 6.1-chan- nel program material or a 6.1-channel processing mode is in use, material for the surround back channel will be out- putted simultaneously through both

the Back Surround Left and Right Speaker Outputs ¡. Connecting only one loudspeaker to these speaker termi- nals will not only deprive you of the ben- efits of 7.1-channel surround modes, such as Logic 7, but will also interfere with the functioning of EzSet speaker calibration, as described on page 51. It may also put undesirable strain on the surround back amplifier circuits and power supplies.

Connections to a subwoofer are normally made via a line-level audio connection from the Subwoofer Output § to the line-level input of a subwoofer with a built-in amplifier.

†Alternate placement for surround speak- ers when only 5.1 channels are used; required placement for back surround speakers in 7.1-channel systems.

The front speakers should be placed the same distance from each other as they are from the listening position. They should be placed at about the same height from the floor as the listeners’ ears will be, or they may be angled toward the listeners.

The center channel speaker should be placed slightly behind the front left and right speakers, and no more than 2 feet above or below the tweeters of the left and right speakers. It may be convenient to place the center speaker in the cradle of the CVPD50 credenza stand, as shown in the drawing.

The JBL Cinema Vision system may be used in 5.1- or 7.1-channel applications. In

5.1-channel applications, two of the surround speakers should be placed slightly behind the listening position and, ideally, should face each other and be at a level higher than the listeners’ ears. If that is not possible, they may be placed on a wall behind the listening position, facing forward.

NOTE: In 5.1-channel systems, the two rear speakers are called simply the surround speakers, whether they are placed to the sides of or behind the listening position. In 7.1-channel systems, there are four surround speakers, two of which are referred to as side surround speakers, due to their placement to the
