System Configuration

In most cases, you will not need to make any adjustments to the output level, as the settings made by running EzSet/EQ are as accurate as those made manually. However, you are able to use the CHANNEL ADJUST menu to trim the settings to suit your personal preferences or to configure the system so that the output set- tings are different from one input source to another. The ability to make individual output level adjustments on a per-input basis is useful for listeners who may prefer different settings for the subwoofer or an individual channel group such as the front speakers when playing musical selections via the CD input as opposed to the movie soundtracks more frequently used with the DVD input. This menu also allows you to adjust the output levels using external sources such as a test disc or other program material that you use as a standard, rather than the system’s test tone.

NOTE: Listeners are often confused about the operation of the surround channels. While some assume that sound should always be coming from each speaker, most of the time there will be little or no sound in the surround channels. This is because they are only used when a movie director or sound mixer specifically places sound there to create ambience, a special effect or to continue action from the front of the room to the rear. When the output levels are properly set, it is normal for surround speakers to operate only occasionally. Artificially increasing the volume to the rear speakers may destroy the illusion of an enveloping sound field that dupli- cates the way you hear sound in a movie theater or concert hall.

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.

To view or change the current Channel Output settings, make certain that the EZSET/EQ MAIN menu (Figure 12) is on the screen. Press the ⁄/¤ Navigation Button DF to move the cursor next to CHANNEL ADJUST and then press the OK/Enter Button E on the TC 30 or the Set Button Q on the ZR 10 remote control. The CHANNEL ADJUST menu (Figure 30) will appear on the screen.

To provide the maximum flexibility, channel output level adjustments may be made either with or without the internal test tone, and when the tone is in use, it may be programmed to automatically circulate among the active channels or to only move from one channel to the next on your command. When the CHANNEL ADJUST menu appears, we recommend that you first run the test tone once in the automatic mode to verify that the speakers have been properly connected. To do this, press the ⁄/¤ Navigation Button DF again until the cursor is on the TEST TONE line and then press the ‹ / › Navigation Button DF until AUTO is in highlighted video. The test tone will then circulate among all channels for five seconds at each position.

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 ˜. 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.

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 DF 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 DF on 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 DF 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 DF until the ➞ cursor is pointing to the TEST TONE line on the menu and then using the ‹/› Navigation Button DF to select MAN in the highlighted video. In the MAN mode, the test tone will also start immediately, but the tone will only be moved to another channel by pressing the ⁄/¤ Navigation Button DF. When the manual sequencing mode is active, the tone is turned off by pressing the ⁄/¤ Navigation Button DF until the ➞ cursor is pointing to the TEST TONE line and the ‹/› Navigation Button DF is then pressed to select OFF in the highlighted video.

The final option for tone adjustment using the menu system is to not use the internal test tone at all. To do this, simply use the ⁄/¤ Navigation Button DF to change the channel and then use the ⁄/¤ Navigation Button DF to change the output level. When making channel output adjustments with- out the internal test tone we strongly recom- mend that you use a test disc in the “repeat” mode on your DVD or CD player so that the sig- nal being used is constant throughout the adjust- ment process.

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 51.

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 DF until the on-screen ➞ cursor is next to the BACK TO MANUAL SETUP line, and then press the OK/Enter Button E on the TC 30 or the Set Button Q to return to the MANUAL

SETUP.

The output level settings may also be adjusted directly (without going into the OSD menu system) at any time, using the TC 30 remote control. To adjust the speaker settings, first press the Devices Button 4 on the TC 30, and then press the Screen Button 6 at the top of the left vertical row, to the left of the AVR image on the remote’s screen. When the images in the LCD change, press the Screen Button 6 next to the box with the word TEST.
