System Configuration

5.To turn the test tone on and have it automati- cally circulate among the channels where a speaker has previously been configured (see page 21), press the /¤ Navigation Button D until the cursor is pointing to the TEST TONE SEQ line on the menu. Next, press the /Navigation Button E until AUTO is shown. At this time the test tone will immediately begin to circu- late clockwise around the room, playing for two seconds 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 circulates, listen to make certain that the sound comes from the speaker position shown in the Main Information Display Ò. 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 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.

6.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 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. The on-screen cursor and the test noise can also be moved directly to the speaker to be adjusted by pressing the /¤ buttons D on the remote.

7.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.

28SYSTEM CONFIGURATION

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 D until 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.

If you find that the output levels 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 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.

When all channels have an equal volume level, the adjustment is complete. Use the /¤ Buttons D to move the cursor next to the TEST TONE line, and press the /Buttons

Euntil the word OFF appears to stop the test tone.

Note that any time a given surround mode is selected, even for a different source input, these output level settings will be used. However, the output levels must be set independently for each surround mode, including variations such as Dolby Pro Logic II-Movie versus Dolby Pro Logic II-Music. Although this may seem to be tedious, it is neces- sary in order to optimize the AVR’s performance when differing methods are employed to steer the audio materials to the various channels. However, the AVR will carry over the settings for one mode to the same mode in a different channel configu- ration, such as Dolby Pro Logic II-Movie and Dolby Pro Logic II-Movie. If you wish, as a shortcut to get started quickly, you may set the levels for Dolby Pro Logic II-Movie and copy down those settings, reentering them for each of the Dolby modes and entering the settings only for those speakers which are available for each mode. Later, it is recommended that you adjust the output lev-

els while listening to various sources, as opposed to the test tone. See page 38 for more information on trimming the output levels to external source material.

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 38.

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 D until the on-screen cursor is next to the BACK TO MASTER MENU line, and then press the

Set Button F to 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 Ò. 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 /¤ buttons D until 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 compensate 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.
