System Configuration

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 9). 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 vto 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 9) to the screen.

When the CHANNEL ADJUST menu first appears, the test tone is off. Use the /¤ Navigation Button Dto select any channel for adjustment using an external source, such as a test disc, from which to judge the output levels. After the cursor is pointing to the channel to be adjusted, press the /Navigation Button

Eto raise or lower the output level. However, before proceeding with any manual adjustment we recommend that you first use the AVR’s internal test tone generator and automatic sequencer to send a tone to each channel so that you may verify that all speaker connections have been properly made.

To turn the test tone on and have it automatical- ly circulate among the channels where a speaker has previously been configured (see page 24), press the /¤ Navigation Button Duntil the cursor is pointing to the TEST TONE SEQ line on the menu. Next, press the /Navigation Button E until AUTO is shown. Next, press the ¤ Navigation Button

Donce so that the cursor is pointing to TEST TONE. Press the /Navigation Button E once to immediately start the test tone at the Front Left speaker. It will circulate clockwise around the room, playing for two sec- onds in each speaker before switching to the next speaker position. The cursor will blink next to the active speaker to indicate which speaker the sound should be coming from.

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 circu- lates, 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 off using the Main Power Switch 1and 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 make these same adjustments with complete manual control over the channel being adjusted by pressing the/¤ Navigation Button Duntil the cursor is pointing to the TEST TONE SEQ line on the menu and then using the /Navigation Button E to select MANUAL in the highlighted video. In the MANUAL mode, the test tone will also start immediately, but the tone will only be moved

to another channel by pressing the /¤ Navigation Button D. When the manual sequencing mode is active, the tone is turned off by pressing the /¤ Navigation Button D until the cursor is pointing to the TEST TONE line and the /Navigation Button

Eis then pressed to select OFF in the highlighted video.

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 32.

When all channels have an equal volume level, the adjustment is complete. Now turn the

Volume down to about –40dB, otherwise the listening level may be too high as soon as the source’s music starts to play. To exit this menu, press the /¤ buttons Duntil the on-screencursor is next to the BACK TO MASTER MENU line, and then press the Set Button Fto return to the MASTER MENU.

The output levels may also be adjusted at any time using the remote control and semi-OSD sys- tem. To adjust the output levels in this fashion, press the Test Button 8. As soon as the button is pressed, the test tone will begin to circulate as indicated earlier. The correct channel from which the test noise should be heard will be shown in the lower third of the video screen and in the Main Information Display ˜. While the test noise is circulating, the proper channel position will also be indicated in the Speaker/ Channel Input Indicators $by a blinking letter within the correct channel. Turn up the

Volume until you can hear the test noise clearly.

To adjust the output level, press the /¤ but- tons Duntil the desired level is shown in the display or on screen. Once the buttons are released, the test noise will begin to circulate again in five seconds.

When all channels have the same output level,

turn the Volume down to about –40dB, otherwise the listening level may be too high as soon as the source’s music starts to play. Afterwards press the Test Tone Selector 8 button again to turn the test tone off and complete the process.

IMPORTANT NOTE: The Output level adjust- ment made will be effective for all inputs, but only for the actual surround mode selected. To be effective for any other mode select that mode (with any input) and repeat the level adjustment described above. This will also allow you to com- pensate level differences between speakers, that may be different with each surround mode, or to increase or decrease the level of certain speakers intentionally, depending on the surround mode selected.

Note: Output level adjustment is not available for the VMAx or Surround Off mode, as no surround speakers are used (so level differences between the speakers in the room cannot occur). But to compensate level differences between stereo, VMAx and other surround modes (inde- pendently from the input selected) the outputs can be adjusted with the Level Trim Adjustment procedure, see page 32, also for the Surround Off (Stereo) and VMAx modes.
