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. We recommend that EzSet/EQ be used when the AVR is first installed to establish the initial level settings. To make changes to the channel output settings, go to the CHANNEL ADJUST submenu within the EZSET/EQ MANUAL SETUP menu (Figure 17). To do this, first press the OSD Button U∫ so that the MASTER MENU (Figure 1) appears. Next, press the ⁄/¤ Navigation Button n© until the cursor is on the EZSET/EQ line, and press the Set Button pœ. Navigate to EZSET/EQ MANUAL SETUP and press the Set Button pœ. In the EZSET/EQ MANUAL SETUP menu, press the ⁄/¤ Navigation Button n© again until the cursor is on the CHANNEL ADJUST line; then press the Set Button pœ to view the CHANNEL ADJUST menu (Figure 21). * CHANNEL ADJUST * → FL : 0dB SBR: 0dB CEN: 0dB SBL: 0dB FR : 0dB SL : 0dB SR : 0dB SUB: 0dB TEST TONE : AUTO OFF MAN LEVEL RESET: OFF ON CH ADJUST: GLOBAL EZSET SETTINGS: OFF ON BACK TO MANUAL SETUP Figure 21 To provide the maximum flexibility, channel output level adjustments may be made either with or without the internal test tone, and when the tone is in use it may be programmed to automatically circulate among the active channels or to only move from one channel to the next on your command. When the CHANNEL ADJUST menu first appears we recommend that you always run the test tone once the automatic mode to verify that the speakers have been properly connected. To do this, press the ⁄/¤ Navigation Button n© again until the cursor is on the TEST TONE line and then press the ‹/› Navigation Button n© until AUTO is in highlighted video. This will cause the test tone to circulate among all of the channels for five seconds at each position. As the test tone circulates, the cursor will flash and move next to each position to indicate where the tone should be coming from. If the tone is coming from a different speaker than the one indicated on the menu screen turn the AVR 445 off using the Main Power Switch A and check the speaker wiring or connections to external power amplifiers to make certain that each speaker is connected to the correct output terminal. When you have verified that all speakers are connected to the correct output terminal, turn the AVR 445 back on and return to this menu to resume the channel adjustment procedure. If any speaker connections were changed we also recommend that you rerun EzSet/EQ before making any manual calibration adjustments. After checking for speaker placement, let the test noise circulate again, and listen to see which channels sound louder than the others. Using the front left speaker as a reference, press the ‹/› Navigation Button n© on the remote to bring all speakers to the same volume level. When the ‹/› Navigation Button n© is pushed, the test noise circulation will pause on the channel being adjusted to give you time to make the adjustment. When you release the button, the circulation will resume after five seconds. Continue to adjust the individual channels until the volume level sounds the same from each speaker. Adjustments should be made with the ‹/› Navigation Button n© on the remote control only, NOT the main volume controls. If you are using a soundpressure level (SPL) meter for precise level adjustment, set the volume so that the meter reads 75dB, C-Weighting Slow. When all channels have an equal volume level, the adjustment is complete. To exit this menu, press the ⁄/¤ Navigation Button n© until the cursor is next to the BACK TO MANUAL SETUP line, and then press the Set Button pœ to return to the EZSET/EQ MANUAL SETUP menu. In addition to having the test tone circulate automatically, you may also turn the test tone on, but advance it from one channel to the next manually. This allows you to make calibration adjustments, but to have more control over the way the test tone is moved among the channels. To circulate the tone manually, first make certain that the CHANNEL ADJUST menu is on the screen, following the instructions shown above, and then press the ⁄/¤ Navigation Button n© until the cursor is on the TEST TONE line. Next, press the ‹/› Navigation Button n© until MANUAL appears. This will start the test tone from the front left speaker position but, rather than circulating to the next channel every five seconds as is the case in the automatic mode, you must press the ⁄/¤ Navigation Button n© to change the channel the test tone is being sent to. When you have circulated through all channels the test tone will stop, but you may restart it by returning to the TEST TONE line again and activating manual sequencing. The final option for output level adjustment using the menu system does not use the internal test tone at all. To do this, simply use the ⁄/¤ Navigation Button n© to change the channel and then use the ‹/› Navigation Button n© to change the output level. When making channel output adjustments without the internal test tone we strongly recommend that you use a test disc in the "repeat" mode on your DVD or CD player so that the signal being used is constant throughout the adjustment process. The output levels may also be adjusted at any time using the remote control and semi-OSD system. To adjust the output levels in this fashion, press the Test Button f. As soon as the button is pressed, the test tone will begin to circulate as indicated earlier. The correct channel from which the test noise should be heard will be shown in the lower third of the video screen and in the Lower Display Line $. While the test noise is circulating, the proper channel position will also be indicated in the Speaker/Channel Input Indicators @ by a blinking letter within the correct channel. To adjust the output level, press the ⁄/¤ Navigation Button n© until the desired level is shown in the display or on the screen. Once the buttons are released, the test noise will begin to circulate again in five seconds. When all channels have the same output level, press the Test Button f again to complete the process. NOTE: Output level adjustment with the test tone is not available in the Surround Off modes. In addition to the controls for selecting channels and the test tone operation, the settings on this menu also allow you to reset the level settings to either the factory default of 0dB or to reestablish the settings that were entered by running EzSet/EQ. To reset all channel levels to 0dB, press the ⁄/¤ Navigation Button n© so that the cursor is pointing to the LEVEL RESET line and then press the ⁄/¤ Navigation Button n© once so that ON appears in highlighted video. To return to the settings established by EzSet/EQ, even if you have made manual changes to the output trims using the steps shown above, press the ⁄/¤ Navigation Button n© so that the cursor is pointing to the EZSET SETTINGS line and then press the ‹/› Navigation Button n© once so ON appears in highlighted video. Remember that after turning the EzSet/EQ settings back on you must return to this menu line and change the setting to OFF if you wish to make any manual trim adjustments. The last setting in this menu enables you to have the output levels remain the same for all inputs or to be adjusted differently for each (or any) input. While most listeners prefer to keep the same output levels for all sources, you may wish to raise or lower some channels, particularly the subwoofer output for a specific source such as a CD that is primarily used for music playback. 32 SYSTEM CONFIGURATION
