signals will be sent to the subwoofer output.

When NONE is selected, surround sound information will be split between the front left and front right outputs. For optimal performance when no surround speakers are in use, the Dolby 3 Stereo mode should be used.

When you have completed your selec- tions for the side surround channels, press the ⁄/¤ Navigation Controls q 4

SURROUNDS. Press the ‹/› Navigation Controls q 6 to select the option that best describes the speakers in use at the left and right back surround positions based on these definitions:

When NONE is selected, the system will adjust so that only 5.1-channel sur- round processing/decoding modes are available and the surround back amplifier channels will not be used. This setting will override any setting made previously in the SYSTEM CONFIGURATION submenu (Figure 7).

When SMALL is selected, the system will adjust so that the full complement of 6.1/7.1 surround processing/ decoding modes are available, and low-frequency information below the crossover point will be sent to the subwoofer output. If you choose this option and there is no subwoofer connected, you will not hear any low-frequency sounds from the sur- round back channels.

When LARGE is selected, the system will adjust so that the full complement of 6.1/7.1 surround processing/decoding modes are available, and a full-range signal will be sent to the surround back channels, with no low-frequency informa- tion sent to the subwoofer output.

When you have completed your selection for the back surround channels, press the ⁄/¤ Navigation Controls q 4

to move the cursor to SUBWOOFER. Press the ‹/› Navigation Controls q 6 to select the option that best describes your system. The choices avail- able for the subwoofer position will depend on the settings for the other speakers, particularly the front left/right positions. If the front left/right speakers are set to SMALL, the subwoofer will automatically be set to ON. If the front left/right speakers are set to LARGE, two options are available:

•If no subwoofer is connected to the CVR700, press the ‹/› Navigation

Controls q 6 so that OFF

appears in the on-screen menu. When this option is selected, all bass infor- mation will be routed to the front left/right “main” speakers.

•If a subwoofer is connected to the CVR700, you have the option to have the front left/right “main” speakers reproduce bass frequencies at all times, and have the subwoofer operate only when the CVR700 is being used with a digital source that contains a dedicated low-frequency effects, or LFE soundtrack. This allows you to use both your main and subwoofer speakers to take advantage of the special bass sounds created for some movies. Note, however, that the subwoofer will only

play the LFE information. Press the ‹/›Navigation Controls q 6 so that ON appears in the on-screen menu.

The BASS MGR setting allows you to use the same speaker configuration set- tings for all inputs, or to have different settings for each input. In most cases, the factory default setting of GLOBAL will be appropriate, as most listeners do not need to have individualized speaker set- tings. However, some listeners, particu- larly those with full-range front speakers that are used for both movies and music, may prefer that different bass manage- ment settings be used when listening to music through a CD player as opposed to a movie from a DVD player, VCR or cable/satellite set-top.

Use the ‹/›Navigation Controls

INDEPENDENT. You may now

change the source input and return to the

Speaker Crossover

Configuration

When all initial speaker “size” settings have been made, you now have the option to take advantage of the CVR700’s Quadruple Crossover system, which allows individual crossover settings to be made for each speaker grouping. Again, if you are using JBL Cinema Vision loud- speakers, you may skip this submenu, as the factory default settings are appropri- ate for your speakers.

The low-frequency crossover point is set by the design of your speakers. Depending on the design and driver complement of your speakers, it is usually the lowest possible frequency the speaker is capable

of reproducing, but it may be different for speakers that include a powered woofer section intended to reproduce the LFE channel. Before making any changes to the settings for the crossover point, we suggest that you find the crossover point for the speakers in each of the four groupings, front left/right, center front, side surround and back surround, by look- ing at the specifications page of each speaker’s owner’s manual, by getting that information from the manufacturer’s Web site, or by contacting your dealer or the manufacturer’s customer service depart- ment. You will need this figure to accu- rately configure the next group of settings.

Note that when any speaker group other than the front left/right speakers is set to LARGE, the crossover may not be adjusted, as the feed will be full-range, with no sound being derived for the sub- woofer at that position. The factory default setting for all speaker positions is 90Hz. To change one of the settings, return to the SPEAKERS submenu (Figure 20), and then scroll to the CROSSOVERS line and select it. The SPEAKER CROSSOVERS submenu (Figure 22) will be displayed. To change the setting for any of the four speaker groups, press the ⁄/¤ Navigation Controls q 4 until the cursor is next to the speaker group where you wish to make a change and then press the ‹/›Navigation Controls q 6 until the desired setting appears. The available choices for low- frequency information to be sent to the subwoofer, rather than to the main speaker channel, are 40Hz, 60Hz, 80Hz, 90Hz, 100Hz, 120Hz and 200Hz. Pick the choice that is identical to the information for your speakers, or if an exact match is not possible, pick the closest choice that is ABOVE the speaker’s low-frequency limit or crossover point to avoid the cre- ation of a low-frequency “hole” where your system will have no bass informa- tion. The setting for the crossover point for the LFE channel, which is created to provide specific low-frequency informa- tion in many movies with digital sound- tracks, may be set to match the cross- over for any of the four speaker groups. Since the crossover point commonly used in the creation of the LFE channel SUBWOOFER is 120Hz, we recom- mend that you select the speaker group whose crossover point is closest to 120Hz. To do this, press the ⁄/¤ Navigation Controls q 4 until the
