System Configuration 9. When you have completed your selection for the surround channel, press the Set button t 31, and then press the ‹/› buttons r on the remote or the Selector buttons 34 on the front panel to change the display to S-W SPEAKER. 10. Press the Set button t 31, and then press the ‹/› buttons r on the remote or the Selector buttons 34 on the front panel to select the option that best describes your system. Select S-W SP YES if a subwoofer is connected to your system. Select S-W SP NO if a subwoofer is NOT connected to your system. Note that when no subwoofer is selected, lowfrequency sounds below 100Hz will be sent to the front-left and front-right speakers, provided that the selection in Step 4 has been set to LARGE. Otherwise, no lowfrequency sounds will be heard at all. This option is not available when the front, center or surround speakers are set to SMALL. 11. When all speaker selections have been made, press the Set button t 31 to return to normal operation. Output Level Adjustment Output level adjustment is a key part of the configuration process for any surround-sound product. It is particularly important for a Dolby Digital receiver such as the AVR 100, as correct outputs will ensure that you hear sound tracks in their proper place 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 ambiance, 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. Before beginning the 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. Finally, make certain that the Balance Control 7 is set to the center "12 o'clock" position. To adjust and calibrate the output levels, follow these steps. For accurate calibration, it is a good idea to make these adjustments while seated in your favorite listening position: 1. Put the AVR 100 in the Dolby Pro Logic mode by pressing the Dolby Pro Logic Selector Ô on the front panel, or by pressing the Surround Mode Selectors 33 on the remote, until PRO LOGIC appears in the Main Information Display N and the PRO LOGIC indicator B lights up. 2. Press the Test Tone button s on the remote. The words T-T FL 0dB will appear in the Main Information Display N and the letters FL will flash once each second. 3. The test noise will immediately begin to circulate in the speakers in a clockwise rotation, pausing at each position for three seconds. As the test noise rotates the speaker position will be shown in the Main Information Display N. NOTE: This is a good time to verify that the speakers have been properly connected. As the test noise circulates, listen to make certain that the sound comes from the speaker position shown in the Main Information Display. If the sound from a speaker location does NOT match the position indicated in the display, turn the AVR 100 off using the Main Power Switch 1 and check the speaker wiring to make certain that each speaker is connected to the correct output terminal. 4. After checking for speaker placement, let the test noise circulate, and listen to see which channels sound louder than the others. Using the front left (FL in the display) speaker as a reference, press the ‹/› buttons r on the remote or the Selector buttons 34 on the front panel on each channel to begin to bring them to the same level. Note that when one of the buttons 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 15 seconds. 5. Continue to adjust the individual speakers until they all have the same volume. Note that adjustments should be made with the ‹/› buttons r on the remote or the Selector buttons 34 on the front panel only, NOT the main volume controls. Then press the Set button t 31 to memorize the change. If you are using a sound pressure (SPL) meter for precise level adjustment, set the volume so that the meter reads 75dB, C-Weighting Slow. NOTE: The subwoofer output level is not adjustable using the test tone. To change the subwoofer level, follow the steps for Output Level Trim Adjustment on page 23. 6. When you have adjusted the outputs so that all channels have the same level, press the Test Tone button s on the remote to complete the adjustment. Delay Settings Due the different distances between the frontchannel speakers and the listening position compared to the surround speakers and the listening position, the amount of time it takes for sound to reach your ears from the front or surround speakers is different. You may compensate for this difference through the use of the delay settings to adjust the timing to tailor the specific speaker placement and acoustic conditions in your listening room or home theater. The factory setting is appropriate for most rooms, but some installations create an uncommon distance between the front and surround speakers that may cause the arrival of frontchannel sounds to become disconnected from surround-channel sounds. To resynchronize the front and surround channels, follow these steps: 1. Measure the distance from the listening/ viewing position to the front speakers. 2. Measure the distance from the listening/ viewing position to the surround speakers. 3. Subtract the distance to the surround speakers from the distance to the front speakers. 17 SYSTEM CONFIGURATION
