Press the ‹/› Buttons n 31 on the remote to select the option that best describes your system based on the speaker definitions shown below.
When SMALL is selected, low-frequency center- channel sounds below 100Hz will be sent only to the subwoofer output. Note that if you choose this option and there is no subwoofer connected, you will not hear any low-frequency sounds from the center channel speaker.
When LARGE is selected, a full-range output will be sent to the center speaker output, and NO center-chan- nel signal will be sent to the subwoofer output.
NOTE: If you choose Logic 7 as the surround mode for the particular input source for which you are con- figuring your speakers, the AVR 225 will not make the “large” option available for the center speaker. This is due to the requirements of Logic 7 processing, and does not indicate a problem with your receiver.
When NONE is selected, no signals will be sent to the center-channel output. The receiver will operate in a “phantom” center-channel mode and center-channel information will be sent to the left and right front-chan- nel outputs. When only front left and right speakers are used, with no center or surround speakers, VMAx is a good alternative mode.
When you have completed your selection for the cen- ter channel, press the ¤ Button q on the remote to change the cursor to SURROUND.
Press the ‹/› Buttons n 31 on the remote to select the option that best describes the surround speakers in your system based on the speaker definitions shown previously.
When SMALL is selected, low-frequency surround- channel sounds below 100Hz will be sent to the sub- woofer 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 speakers.
When LARGE is selected, a full-range output will be sent to the surround-channel outputs, and NO sur- round-channel signals will be sent to the subwoofer output.
When NONE is selected, surround sound informa- tion will be split between the front left and right out- puts. Note that for optimal performance when no sur- round speakers are in use, the Dolby 3 Stereo mode should be used instead of Dolby Pro Logic II. If only front left and right speakers are available, select one of the two VMAx modes or “Surround Off”.
When you have completed your selection for the sur- round channel, press the ¤ Button q on the remote to move the cursor to SUBWOOFER.
Press the ‹/› Buttons n 31 on the remote to select the option that best describes your system.
The choices available 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 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 225, press the ‹/› Buttons n 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 225, 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 AVR 225 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 created for certain movies. Press the ‹/› Buttons n 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 listen-
ing to, press the ‹/› Buttons n 31 on the remote so that SUB L/R+LFE 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 bass frequencies below 100Hz.
When all speaker selections have been made, press the ¤ Button q until the on-screen › cursor points to RETURN TO MENU and press the Set Button o to return to the MASTER MENU.
The speaker configuration may also be changed at any time without using the Full-OSD on-screen menu system by pressing the Speaker Select button on the front panel ı or remote 32 . Once the button is pressed, FNT SPKR will appear in both the lower
third of the video display and the Main Information Display S.
Within three seconds, press either the front-panel ‹/› Selector Buttons 5 or the ⁄/¤ Buttons mq on the remote to select a different speaker position, or press the Set Button Ôo to begin the adjustment process for the front left and right speakers.
When the Set Button Ôo has been pressed and the system is ready for a change to the speaker set- ting, the on-screen display and Main Information Display S will read FNT LARGE or FNT SMALL, depending on the current setting. Press the front-panel ‹/› Selector Buttons 5 or the ⁄/¤ Buttons mq on the remote until the desired setting is shown, using the instructions for “large” or “small” described earlier.
If the configuration for another speaker position needs to be changed, press the front-panel ‹/› Selector Buttons 5 or the ⁄/¤ Buttons mq on the remote to select a different speaker position, and then press the front-panel ‹/› Selector Buttons 5 or the ⁄/¤ Buttons mq on the remote until the correct speaker setting is shown.
To assist in making speaker configuration settings, the icons in the Speaker/Channel Input Indicators L change as the speaker type is selected at each posi- tion. 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.
For example, in Figure 6, the left-front and right-front speakers are set for “large,” the center, left-surround (SL) and right-surround (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.”
