SYSTEM CONFIGURATION However, if you have a digital video source or a digital video display that causes lack of lip sync you may use the A/V Sync adjust feature to delay the audio signal as it is sent to all channels (as opposed to the individual settings) so that the picture and sound are brought back together. We recommend that this adjustment be made using the direct access controls on the remote, as shown below. That enables you to see the image while making the adjustment; however, you may also adjust it here using the menu system. To adjust the A/V Sync delay, press the ⁄/¤ Navigation Button n so that the › cursor is pointing to the A/V Sync Delay line on the menu and then press the ‹/› Navigation Button o to delay the sound sufficiently so that it matches the on-screen video. Since the A/V Sync Delay setting is best made while viewing the video program that is out of sync with its audio track, we strongly recommend that rather than using the menu system. To do that, first press the Delay Select Button on the Remote Z. The A/V Sync Delay setting is first, and it may be adjusted by pressing the Set Button p within five seconds of when the A/V SYNC DELAY message appears in the on-screen display and the Lower Display Line ¯. Then, press the ‹/› Navigation Button o to enter the desired delay setting that brings the video and sound back in sync. Press the Set Button p again to enter the setting. Note that the A/V Sync delay setting is unique to each video input source, so you may enter a different setting to compensate for the differences between any product attached to the Video 1, 2, 3 or 4 inputs. To change one of the individual speaker positions directly, press the Speaker Select Button Z, followed by the ⁄/¤ Navigation Button n to select the desired position as that name appears in the on-screen display and the Lower Display Line ¯. When the name of the speaker position to be adjusted appears, press the Set Button p within 5 seconds. Press the ‹/› Navigation Button o to enter the desired delay setting for that speaker and then press the Set Button p to enter the setting. The ⁄/¤ Navigation Button n may be used to select another position, or simply wait 5 seconds for the system to time out and return to normal operation. When all delay settings made using the menu system have been completed, press the ⁄/¤ Navigation Button n until the › cursor is pointing to the BACK TO MASTER MENU line and press the Set Button p. Output Level Adjustment Output level adjustment is a key part of the configuration of any surround sound product. It is particularly important for a digital receiver such as the AVR 335, as correct outputs ensure that you hear soundtracks 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 or 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. If you have already calibrated your system using EzSet+ the delay settings shown will reflect the results of the measurements made by EzSet+. No further changes are needed unless you wish to change a specific item to reflect your personal taste or a nonstandard system configuration. Before beginning the output level 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 typical listening session. Output levels may also be adjusted manually, either to set them to a specific level with an SPL meter, or to make fine-tuning adjustments to the levels obtained using the EzSet+. Using the Full-OSD System Manual output level adjustment is most easily done through the CHANNEL ADJUST menu (Figure 11). 1. If you have not used EzSet+, make certain that all speaker positions have been properly configured for their "large" or "small" settings (see "Speaker Setup" on page 22). 2. Adjust the volume to -10dB as shown in the on-screen display or Lower Display Line ¯. 3. If you are already at the MASTER MENU, press the ¤ Button n until the on-screen › cursor is next to the CHANNEL ADJUST line. If you are not at the MASTER MENU, press the OSD Button v to bring up the MASTER MENU (Figure 1), and then press the ¤ Button n until the on-screen › cursor is next to the CHANNEL ADJUST line. Press the Set Button p to bring the CHANNEL ADJUST menu (Figure 11) to the screen. * CHANNEL ADJUST * › FL : 0dB SBR: 0dB CEN: 0dB SBL: 0dB FR : 0dB SL : 0dB SR : 0dB SUB: 0dB CHANNEL RESET:OFF TEST TONE SEQ:AUTO TEST TONE :OFF BACK TO MASTER MENU Figure 11 When the CHANNEL ADJUST menu first appears the test tone is off. If desired, you may immediately use the ⁄/¤ Navigation Button n to select any channel for adjustment using an external source, such as a test disc, from which to judge the output levels. After the › cursor is pointing to the channel to be adjusted, press the ‹/› Navigation Button o to raise or lower the output level. However, before proceeding with any manual adjustment we recommend that you first use the AVR's internal test tone generator and automatic sequencer to send a tone to each channel so that you may verify that all speaker connections have been properly made. 4. To turn the test tone on and have it automatically circulate among the channels where a speaker has been configured (see page 22), press the ⁄/¤ Navigation Button n until the › cursor is pointing to the TEST TONE SEQ line on the menu. Next, press the ‹/› Navigation Button o until AUTO is shown in highlighted video. At this time the test tone will immediately begin to circulate clockwise around the room, playing for two seconds in each speaker before switching to the next speaker position. The › cursor will blink next to the active speaker to indicate which speaker the sound should be coming from. As the test noise circulates, listen to make certain that the sound comes from the speaker position shown in the Lower Display Line T, next to the › cursor in the on-screen display, and by the flashing indication in the Speaker/Channel Input Indicators ˆ. If the sound from a speaker location does NOT match the position indicated in the display, turn the AVR 335 off using the Main Power Switch 1 and check the speaker wiring or connections to external power amplifiers to make certain that each speaker is connected to the correct output terminal. 5. After checking for speaker placement, let the test noise circulate again, and listen to see which chan- SYSTEM CONFIGURATION 25
