System Configuration

You may repeat this procedure as many times as necessary to achieve a desired result. In order to prevent possible damage to your hearing or your equipment, we emphasize that you should avoid setting the master volume above 0dB.

NOTE: The subwoofer output is not adjusted when the test tone is in use. To adjust the subwoofer output you must use an external source, following the instructions on page 36.

Manual Output Level Adjustment 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 remote.

Manual output level adjustment is most easily done through the CHANNEL ADJUST menu (Figure 8). If you are already at the main menu, press the ¤ Button Duntil the on- screen › cursor is next to the CHANNEL ADJUST line. If you are not at the main menu, press the OSD Button v to bring up the MASTER MENU (Figure 1), and then press the ¤ Button Dfour times so that the on-screen › cursor is next to the CHANNEL ADJUST line. Press the Set Button Fto bring the CHANNEL ADJUST menu (Figure 8) to the screen.

Once the menu appears on your video screen, first use the ⁄ Button Dto move the on- screen › cursor so that it is next to the TEST TONE line. Press the ‹/ › Buttons E

so that ON is highlighted.

You will hear a test noise circulate from speaker to speaker in a clockwise direction around the room. The test noise will play for two seconds in each speaker before circulating, and a blinking on-screen cursor will appear next to the name of each speaker location when the sound is at that speaker. Now turn up the volume until you can hear the noise clearly.

IMPORTANT NOTE: Because this test noise will have a much lower level than normal music, the volume must be lowered after the adjustment for all channels is made, but BEFORE you return to the main menu and the test tone turns off.

NOTE: Remember 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 comes from a speaker location that does NOT match the position indicated in the display, turn the AVR 5550 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.

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 ‹/› Buttons E on the remote to bring all speakers to the same volume level. 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 five seconds. The on-screen cursor › and the test noise can also be moved directly to the speaker to be adjusted by pressing the ⁄/¤ buttons Don the remote.

Continue to adjust the individual channels until the volume level sounds the same from each speaker. Note that adjustments should be made with the ‹/› Buttons E on the remote only, NOT the main volume controls.

If you are using a sound-pressure level (SPL) meter for precise level adjustment with the test

tone, open the main Volume Control to - 15dB and set the individual output level for each channel so that the meter reads 75dB, C-Weighted Slow. After all settings are made turn the main volume down.

You may also adjust the output levels manually while using the level indication feature of the EzSet remote. To activate the sensor and indica- tor, simply press and release the SPL Indicator

Select Button on the remote while the test tone is circulating and set the main Volume

Control to -15dB (respectively higher or lower, if needed, as outlined above).

The Program/SPL Indicator 2will change color to indicate the level. Adjust the level using the ‹/› Buttons E on the remote until the LED lights green for all channels. When it is red, the level is too high; when it is orange, the level is too low. Press the SPL Indicator Select button when you are finished to turn the

sensor and Indicator off.

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 36.
