System Configuration
If the front left/right speakers are set to LARGE, three options are available:
•If no subwoofer is connected to the
AVR 310, press the ‹/› buttons o 31 on the remote so that NONE appears in the on-screen menu. 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 310, 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 310 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 o 31 on the remote so that SUB (LFE) appears in the on-screen menu.
•If a subwoofer is connected and you wish to use it for bass reproduction in conjunction with the main front left/right speakers, regardless of the type of program source or surround mode you are listening to, press the ‹/› buttons o 31 on the remote so that SUB LFE+L/R appears in the on-screen menu. When this option is selected, a “complete” feed will be sent to the front left/right “main” speakers, and the subwoofer will receive the bass frequencies under frequency selected in the next option setting on this menu, as described below.
When you have completed your selection for the subwoofer, press the ¤ button n on the remote to change the cursor to SUB X-OVER FREQ. The subwoofer crossover setting may only be adjusted using the on-screen display system.
At this line you will select the frequency at which bass information is directed to the Subwoofer Output ¤. The choices available will depend on the setting made previously for the front left/right speakers. When making these selections, choose the crossover frequency that is closest to that of your front left/right speakers, or the upper frequency limit of your subwoofer. This figure is normally printed in the Owner’s Manual or data sheet for the speakers, or consult the speaker’s manufacturer.
•When the front speakers have been set to LARGE, the crossover choices are 40
Hz or 60 Hz to match the typical crossover points of full range speakers. Choose the option that is closest to your speakers’ design.
•When the front speakers have been set to SMALL, the crossover choices are 80 Hz or 100 Hz to match the typical crossover points of the smaller speakers used in satellite speaker systems. Choose the option that is closest to your speakers’ design.
When all speaker selections have been made, press the ¤ button n and then the Set button p to return to the main menu.
The Speaker Configuration may also be changed at any time without using the full-OSDon-screen menu system by pressing the Speaker Select button on the front panel ı or remote 32 . Once the button is pressed, FNT SPEAKER will appear in both the lower third of the video display and the Main
Information Display Y.
Within three seconds, either press the front panel ‹/› Selector buttons 5 or the ⁄/¤ buttons n on the remote to select a different speaker position, or press the Set button Ôp to begin the adjustment process for the front left and right speakers.
When the Set button Ôp has been pressed and the system is ready for a change to the speaker setting, the on-screen display and Main Information Display Y will read FNT LARGE or FNT SMALL, depend- ing on the current setting. Press the front panel
‹/› Selector Buttons 5 or the ⁄/¤ buttons n on the remote until the desired setting is shown, using the instructions for “large” or “small” shown earlier.
If the configuration for another speaker position needs to be changed, press the front panel ‹/› Selector buttons 5 or the ⁄/¤ buttons n on the remote to select a different speaker position, and then press the front panel ‹/› Selector buttons 5 or the ⁄/¤ buttons n on the remote until the correct speaker setting is shown.
To assist in making speaker configuration set- tings, the icons in the Speaker/Channel Input Indicators Q 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 with circles inside them are lit, the speaker is set for “large.” When no indicator appears at a speaker location, that position is set for “none” or “no” speaker.
NOTE: These icons are available only when making setup changes in the semi-OSD mode.
As an example, in Figure 6 below, the left front and right front speakers are set for “large,” the center, left surround (LS) and right surround (RS) speakers are set for small, and a sub- woofer is set, as shown by the box with the abbreviation “LFE”, which stands for “low- frequency effects.”

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 310, as correct outputs will ensure that you hear sound tracks with the proper directionality and intensity.
IMPORTANT NOTE: Listeners are often confused 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 ambience, 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 occasionally. Artificially increasing the volume to the rear speakers may destroy the illusion of an enveloping sound field that duplicates the way you hear sound in a movie theater or concert hall.
