NOTE: If you choose Logic 7 as the sur- round mode for the particular input source for which you are configuring your speakers, the AVR 120 will not make the LARGE option available for the center speaker. This is due to the requirements of Logic 7 pro- cessing, and does not indicate a problem with your receiver.
When CEN NONE is selected, no signals will be sent to the center-channel output.
7.When you have completed your selection for the center channel, press the Set Button o21 , and then press the ‹/› Buttons n 30 on the remote or the Selector Buttons 5 on the front panel to change the display to SUR SPEAKER.
8.Press the Set Button o21 again, and then use the ▲/▼ Buttons mq on the remote or the Selector Buttons 5 on the front panel to select the option that best describes your system based on the speaker definitions shown in the preceding section.
When SUR SMALL is selected, low- frequency surround-channel sounds will be sent to the subwoofer output only. Note that if you choose this option and there is no subwoofer connected, you will not hear any low-frequency sounds from the surround speaker.
When SUR LARGE is selected, a full- range output will be sent to the surround- channel outputs, and NO surround-channel signals will be sent to the subwoofer output.
When SUR NONE is selected, surround sound information will be split between the front-left and front-right outputs. Note that for optimal performance when no surround speakers are in use, the Dolby 3 Stereo mode should be used instead of Dolby Pro Logic II.
9.When you have completed your selection for the surround channel, press the Set Button o21 , and then press ▲/▼ Buttons mq on the remote or the Selector Buttons 5 on the front panel to change the display to S-W SPEAKER.
10.Press the Set Button o21 , and then press the ▲/▼ Buttons mq on the remote or the Selector Buttons 5 on the front panel to select the option that best describes your system.
The choices available for the subwoofer position will depend on the settings for the other speak- ers, particularly the front left/right positions.
If the front left/right speakers are set to SMALL, the subwoofer will automatically be set to SUB, which is the “on” position.
If the front left/right speakers are set to LARGE, three options are available:
•If no subwoofer is connected to the
AVR 120, press the ▲/▼ Buttons mq on the remote so that SUB NONE appears in the Main Information Display
F. When this option is selected, all bass information will be routed to the front left/right “main” speakers.
•If a subwoofer is connected to the AVR 120, you have the option to have the front left/right “main” speakers reproduce bass frequencies at all times, and have the sub- woofer operate only when the AVR 120 is being used with a digital source that con- tains 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 created for certain movies. Press ▲/▼ Buttons mq on the remote so that SUB (LFE) appears in the Main Information Display F.
•If a subwoofer is connected and you wish to use it for bass reproduction in conjunc- tion with the main front left/right speakers, regardless of the type of program source or surround mode you are listening to, press the ▲/▼ Buttons mq on the remote so that SUB L/R+LFE appears in the Main Information Display F. When this option is selected, a “complete” feed will be sent to the front left/right “main” speak- ers, and the subwoofer will receive bass fre- quencies below 100Hz.
11.When all speaker selections have been made, press the Set Button o21 to return to normal operation.
Output Level Adjustment
Output level adjustment is a key part of the configuration process for any surround sound product. It is particularly important for a Dolby Digital receiver such as the AVR 120, as correct output levels will ensure that you hear sound tracks in their proper place with the proper directionality and intensity.
IMPORTANT NOTE: Listeners are often con- fused about the operation of the surround channels. While some assume that sound should always be coming from each speaker, most of the time there will be little or no sound in the surround channels. This is because they are only used when a movie director or sound mixer specifically places sound there to create ambiance, a special effect or to continue action from the front of the room to the rear. When the output levels are properly set, it is normal for surround speakers to operate only occasion- ally. Artificially increasing the volume to the rear speakers may destroy the illusion of an envelop- ing sound field that duplicates the way you hear sound in a movie theater or concert hall.
Before beginning the adjustment process, make certain that all speaker connections have been properly made. The system volume should be set to the level that you will use during a typi- cal listening session. Finally, make certain that the Balance Control * is set to the center “12 o’clock” position.
To assist in making speaker configuration set- tings, the icons in the Speaker/Channel Input Indicators L change as the speaker type is selected at each position. When only the center icon box containing the abbreviation for the speaker position is lit, the speaker is set for “small.” When the inner box and the two outer boxes are lit, the speaker is set for “large.” When no indicator appears at a speaker loca- tion, that position is set for “none” or “no” speaker.
For example, in the following figure, the left front and right front speakers are set for “large,” the center, surround left (SL) and sur- round right (SR) speakers are set for small, and a subwoofer is set, as shown by the box with the abbreviation “LFE”, which stands for “low- frequency effects.”
