System Configuration

Before beginning the output level adjustment process, make certain that all speaker connec- tions have been properly made. The system volume should be turned down at first.

For the easiest set-up, follow these steps while seated in the listening position that will be used most often:

1.Make certain that all speaker positions have been properly configured for their “large” or “small” settings (as outlined above) and turn off the OSD system if it is in use.

2.Adjust the volume so that it is at -15, as shown in the on-screen display or Main Information Display Ò.

3.Select any input associated with the surround mode for which you want to adjust the output levels. Remember that the same adjustments must be made with all other surround modes you´ve in use.

4.Manual output level adjustment is most easily done through the CHANNEL ADJUST menu (Figure 10). If you are already at the main menu, press the ¤ Button Duntil the on-screen cursor is next to the MAN- UAL SETUP 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 Dthree times so that the on-screen cursor is next to the MANUAL SETUP line. Press the Set Button Fto bring the MANUAL SETUP menu (Figure 6) to the screen, and then scroll down until the cursor is pointing at the CHANNEL ADJUST line and press the Set Button F.

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.

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 23), 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. 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 circu- lates, 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 1and check the speaker wiring or connections to external power amplifiers to make certain that each speaker is connected to the correct output terminal.

NOTE: Remember that when your system has only a single Surround Back speaker and is thus configured for 6.1-channel operation, you will hear the test tone twice from the back speaker, once with the SBL indication and once with the SBR indication. This is normal, and it allows you to adjust the output balance for the mixing cir- cuit that creates a 6.1 output when 7.1 modes such as Logic 7/7.1 are used.

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.

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.

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 mas- ter 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 Dto move the cursor next to the TEST TONE line, and press the / Buttons E until 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 necessary in order to optimize the AVR’s per- formance when differing methods are employed to steer the audio materials to the various chan- nels. However, the AVR will carry over the set- tings for one mode to the same mode in a differ- ent channel configuration, such as Dolby Pro Logic IIx-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 IIx-Movie and copy down those settings, reentering them for each of the Dolby modes and entering the settings only for those speakers which are avail- able for each mode. Later, it is recommended that you adjust the output levels while listening to
