47ADVANCED FUNCTIONSSharpness AdjustmentContrary to intuition, the picture will appear sharper and clearerwith the sharpness backed off from the maximum setting. Reducethe sharpness setting on your television, and the setting on theAVR 7550HD, if necessary, to minimize the appearance of any whitelines between the bars in the gray scale portion of the test screen.Convergence and Edge FocusThe crosshatch pattern that surrounds the test screen may be usedto evaluate edge focus and convergence in front- or rear-projectionvideo displays. If you are unable to improve the picture using theavailable controls, contact the video display manufacturer’s authorizedservice representative for assistance.When you have finished making any video adjustments, press theBack/Exit Button.MULTIZONE OPERATIONWith the multizone system in use, you may enjoy an exciting 5.1-or 5.2-channel home theater presentation in the main listeningarea, while others listen to the same materials or an entirelydifferent presentation in another room.Although installation of a multizone system is not complicated, itrequires running wires inside walls. Check your local building codesand comply with the requirements for in-wall wiring systems, toprevent the possibility of a dangerous situation. If you have anyquestions about installing a multizone system, it is strongly recom-mended that you contact a professional custom installer. See StepEleven of the Installation section on page 25 for instructions oninstalling a multizone system.Operating the Multizone SystemThe AVR 7550HD’s multizone system is accessed using the on-screen Zone 2 menu. Press the AVR Settings Button, and use the1/5 Buttons to navigate to the Zone 2 line. Press the OK Button todisplay the Zone 2 menu. See Figure 36.NOTE: When the Zone 2 Video Output is connected to adisplay, a text-based version of the menu will appear. However,no menus will appear when USB, Internet Radio or the Networkis selected as the source in either the main or remote zone,and a different source is selected for the other zone.Figure 36 – Zone 2 MenuStatus: Turns the multizone system on or off. When no one islistening in the remote room, leave this setting at the default of OFF.Source: Indicates the source input for the remote zone. You mayselect a different source from the main listening area. However, if thesame source has been selected for both the main listening area andthe remote zone, listeners in both areas will hear the same content.NOTE: Only analog audio sources, including The Bridge II,are available to the multizone system. The USB, Network andInternet Radio sources are also available. To hear digital devices,such as a CD player, in the remote zone, follow these steps:1. In addition to a digital audio connection, connect the sourcedevice’s analog audio outputs to the AVR. Make a note inTable A5 in the appendix on which set of inputs was used.2. In the Info Settings menu, leave the Audio Input FromSource setting at the digital audio input. Scroll down to theZone 2 Audio setting and select the analog audio input.Volume: The volume is controlled separately for the remote zone.Surround Back Amps: Reassign the surround back channelsto the multizone system. When this line is set to Zone 2, you mayonly configure the main listening room for up to 5.2 channels.EzSet/EQ II will only configure the main system. Use the ManualSetup section of the Speaker Setup menu to configure the remotespeakers with this setting at Main Room, then return this settingto Zone 2.Carrier Out: The Carrier IR Output passes the full remoteinfrared signal, rather than a signal stripped of the carrier frequency,as is available at the Remote IR Output. This setting determines thesource for the Carrier IR Output.• Zone 2: Uses the Zone 2 IR Input.• Front Panel: Uses either the front-panel IR receiver or the RemoteIR Input.• A-BUS: Uses the A-BUS system.To operate the multizone system using the main remote, slide theZone Select Switch at the bottom of the remote to the “2” position.To select a zone using the Zone 2 remote, press the Zone Selector,and the Zone Indicator will turn green when the remote is set tooperate Zone 1, or red to operate Zone 2.SYSTEM SETTINGSThe AVR 7550HD offers system settings for ease of use.
