54 54ADVANCED FUNCTIONSFigure 89 – Manual Speaker Setup MenuThere are four submenus in the Manual Speaker Setup Menu: SpeakerSize, Speaker Crossover, Delay Adjust and Channel Adjust. As eachsubmenu’s name is highlighted, its settings will be displayed. To navigatethe Manual Speaker Setup menus, press the Set Button when thedesired submenu is highlighted, and the first line of the submenu willbe highlighted. Press the Set Button to change a setting. Use the ‹/›Buttons to scroll through the options, pressing the Set Button again toselect an option. Use the ⁄/¤ Buttons to select another setting inthe submenu. When you are finished making all of your adjustmentsin a particular submenu, press the ‹ Button to return to the list ofsubmenus, and use the ⁄/¤ Buttons to select another submenu.If you have run EzSet/EQ, the values obtained during that process willappear in these menus. You may use them as a starting point for youradjustments, which is recommended, or you may reset the values in theDelay Adjust and Channel Adjust submenus.Each submenu’s settings are dependent upon the previous submenu,and therefore we recommend you visit the menus in the order shown.Speaker Size MenuMove the cursor to the Size line and press the Set Button to display theSpeaker Size submenu. See Figure 89.The Speaker Size menu lists each of the speaker groups. You will beprogramming the correct setting for each group, indicating how manyspeakers are in your system and what their capabilities are, based onthe information you obtained in Step One – Determine Speaker Size.Each of the main speaker groups can be set to one of three settings:LARGE, SMALL or NONE. These settings don’t refer to the physical sizeof the speaker, but rather to its frequency range. These may or may notturn out to be the same.If the lower number of the frequency response for your speakers is lessthan 100Hz, choose the LARGE setting. If this number is 100Hz orgreater, choose the SMALL setting. If you don’t have a speaker installedin that position, choose NONE. You may record the speaker size settingin Table A5 in the appendix.As you can see, the system requires you to use both speakers in a pair.For example, you can’t connect just a front left speaker without a rightspeaker, or just a right surround (rear) speaker without a left one.However, you can connect only the front speakers, or both front andsurround speakers without a center, or the front left/right and centerspeakers without any surrounds.Usually you would not connect the surround back speakers without alsoconnecting the front and side surround speakers. However, the AVR 347has the capability to reassign the surround back amplifier channels tothe multiroom system, enabling you to use these channels to power apair of speakers in another room independently of the speakers you usein your main listening area. In that case you might connect speakers tothe surround back/multiroom terminals without using the side surroundspeaker terminals at all.LEFT/RIGHT: This line tells the AVR 347 the capabilities of your frontleft and right speakers. Use the ‹/› Buttons to select either SMALLor LARGE for these speakers.CENTER: Move the cursor to the line for the center speaker, and usethe ‹/› Buttons to select a setting for this speaker.NOTE: If the receiver is currently in one of the Logic 7 surroundmodes, which will be the case the first time you turn on thereceiver, you won’t be able to set the center speaker to LARGE,due to the requirements of the Logic 7 processor. You may usethe SMALL setting instead. As you listen to the receiver, if youfind the SMALL setting is not satisfactory, change the surroundmode to one of the Dolby Pro Logic II modes (using theSurround Setup menu, and return to this menu to change thecenter speaker to the LARGE setting.SURROUND: Move the cursor to the line for the side surroundspeakers, and use the ‹/› Buttons to select the SMALL, LARGE orNONE setting for these two speakers.SURR BACK: Use the ‹/› Buttons to select the SMALL, LARGE orNONE setting for the surround back speakers.The AVR 347 is one of the few receivers in its class to include multi-room capability. With assignable surround back amplifier channels, set-ting up a multiroom system is more convenient than ever, no longerrequiring an external amplifier to power the remote speakers. This lineindicates whether the surround back channels are in use with the multi-room system by indicating MAIN when the multiroom system is not inuse and MULTI when it is. It is not possible to change the status of thesurround back channels from this menu; the MAIN/MULTI indication isfor information only. The status may only be changed by activating ordeactivating the multiroom system using the MULTI ROOM SETUP menuas described in the Multiroom Operation section on page 58.SUBWOOFER: Move the cursor to the line for the subwoofer, which isprogrammed a little differently. The subwoofer’s “size” setting dependsupon how you programmed the front left and right speakers.• If you set the front speakers to SMALL, the subwoofer setting willbe SUB (LFE), and you won’t be able to change it. All low-frequencyinformation will always be sent to the subwoofer. If you don’t havea subwoofer, you may wish to set your front speakers to LARGEso as not to lose this information, but you may need to lower thevolume to avoid adverse results. We recommend that you eitherupgrade to full-range speakers or add a subwoofer to your systemat the earliest opportunity.
