Manual Output Level Adjustment

As the individual channels are set, the channel name and the adjust- ment offset will appear in the on- screen display (if connected) and the Main Information Display

˜. While the level is changing, the Program/SPL Indicator c will change colors to reflect the output level in relation to the refer- ence. A red indication shows that the level is too high, while an amber indication shows that the level is too low. When the indicator is green, the level is correct, and the test noise will move to the next channel.

While adjustments are being made, the red LED under the AVR Selector f will flash. This is normal, and indicates that EzSet is operating.

7.After the test noise has circulated once through each channel, it will send the tone to each channel once again, to verify the settings.

8.After two complete circulations of the tone, the levels are set. The Program/SPL Indicator c will remain green at each channel. Upon completion of the second circulation, the Program/SPL Indicator c will flash green twice and then go out. The tone will stop and the AVR580 will return to normal operation.

If you find that the output levels chosen by EzSet are either uncomfortably low or high, you may repeat the procedure. Return to Step 2 and adjust the master volume either slightly higher or lower to accommodate your particular room layout and your tastes. You may repeat this pro- cedure as many times as necessary to achieve a desired result. In order to pre- vent possible damage to your hearing or your equipment, we emphasize that you should avoid setting the master volume above 0dB.

If the levels of the surround back speak- ers in your 6.1- or 7.1-channel system seem very high in comparison to the other channels, it may be due to your pointing the remote away from these speakers during the level-setting process, as the microphone sensor is located on the front of the remote (opposite the position of the surround back speakers situated behind you). This may be corrected by using the manual output level adjust-

ment process described below. While checking the level of each speaker, point the remote toward the ceiling and check the level as indicated by the SPL Indicator c. Point the remote toward the AVR in order to transmit the com- mands to raise or lower the level for a particular channel. Point the remote toward the ceiling again to check whether the SPL Indicator c reflects a correct level, or further adjustment is necessary.

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 man- ually, 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.

Figure 8

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

When the CHANNEL ADJUST menu appears, press the ¤ Button n until the on-screen cursor is next to the TEST TONE line. Press the /Buttons o 37 so that ON is high- lighted and the AVR’s internal test tone will begin to circulate from speaker to speaker in a clockwise direction into all speakers. The test noise will play for two seconds in each speaker before circulat- ing, and a blinking on-screen cursor will

appear next to the name of each speaker location when the sound is at that speaker.

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 from a speaker location does NOT match the position indicated in the display, turn the AVR580 off using the Main Power Switch 1 and check the speaker wiring or connections to external power ampli- fiers 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

o37 on the remote to bring all speak- ers to the same volume level. When one of the /Buttons o 37 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 chan- nels until the volume level sounds the same from each speaker. Adjustments should be made with the /Buttons

o37 on the remote only, NOT the main volume controls. If you are using a sound-pressure level (SPL) meter for precise level adjustment, set the volume so that the meter reads 75dB, C-Weighting Slow.

You may also adjust the output levels manually while using the level indication feature of the EzSet remote. To activate the sensor and indicator, simply press and release the SPL Selector Button 41 on the remote while the test tone is circulat- ing. The Program/SPL Indicator c will change color to indicate the level. Adjust the level using the /Buttons

o37 until the LED lights green for all channels. When it is red, the level is too high; when it is amber, the level is too low. Press the SPL Selector Button 41 when you are finished to turn the sensor and indicator off.

NOTE: The subwoofer level is not adjustable when the normal test tone is in use. The subwoofer output level may be adjusted when the channel levels are
