System Configuration

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 120 in the Dolby Pro Logic II mode by pressing Surround Mode Selector 7 on the front panel, or by pressing the Surround Mode Selector j on the remote, until PRO LOGIC II scrolls across the Main Information Display F and the Pro Logic II Indicators D29 light.
2.Press the Test Button h on the remote.
3.The test noise will immediately begin to circulate among the speakers in a clock- wise rotation, pausing at each position for three seconds. As the test noise rotates, the speaker position will be shown in the Main Information Display F.
NOTE: This is a good time to verify that the speakers have been properly connect- ed. 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 posi- tion indicated in the display, turn the AVR 120 off using the Main Power Switch 1 and check the speaker wiring to make certain that each speaker is con- nected 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 oth- ers. Using the front left (FL in the display) speaker as a reference, press the ▲/▼ Buttons mq on the remote or the Selector Buttons 5 on the front panel
for each channel to begin to bring them to the same level. Note that when one of the buttons is pushed, the test noise circula- tion 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 mq on the remote or the Selector Buttons 5 on the front panel only, NOT the main volume controls. Then press the Set Button o21 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,
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 26.
6.When you have adjusted the output so that all channels have the same level, press the Test Button h on the remote to complete the adjustment.
Delay Settings
Due to the different distances between the
The factory setting is appropriate for most rooms, but some installations create an uncom- mon distance between the front and surround speakers that may cause the arrival of front- channel sounds to become disconnected from
To resynchronize the front and surround chan- nels, 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 speak- ers from the distance to the front speakers.
a.When setting the delay time for the Dolby Digital surround modes, the opti- mal delay time is the result of that sub- traction. For example, if the front speak- ers are ten feet away and the surround speakers are five feet away, the optimal delay time is figured as
b.When setting the delay time for the Pro Logic II mode, take the result of the subtraction and add 15 to obtain the optimal delay time. For example, if the front speakers are ten feet away and the surround speakers are five feet away, the optimal delay time is figured as
NOTE: The Theater and Hall modes use a fixed, nonadjustable delay time.
The Dolby Digital mode also includes a separate setting for the
If the distances are equal, no further adjust- ment is required and the center delay should be set to zero. If the distance to the front speakers is greater than the distance to the center speaker, you may wish to reposition the speak- ers by moving the
If repositioning of the speakers is not possible, adjust the center delay time, adding one mil- lisecond of
