System Configuration
8.After the test noise has circulated once through each channel, it will send the tone to each channel once again, to verify the settings.
9.After two complete circulations of the tone, the levels are set. The Program/SPL Indicator 2will remain green at each channel. Upon completion of the second circu- lation, the Program/SPL Indicator 2will flash green twice and then go out. The tone will stop and the AVR 4500 will return to nor- mal operation.
If you find that the output levels chosen by EzSet are either much lower or much higher than the "0dB" reference setting or even at the limits of the
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

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
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 Y. If the sound comes from a speaker location that does NOT match the position indicated in the display, turn the AVR 4500 off using the Main Power Switch 1 and check the speaker wiring or con- nections to external power amplifiers to make certain that each speaker is connected to the cor- rect 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
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.

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
