Output Level Adjustment

With Source Signals

Normal output level adjustment for the AVR is established using the test tone, as outlined on page 27-28. In some cases, however, it may be desirable to adjust the output levels using program material such as a test disc, or a selection you are familiar with. Additionally, the output level for the subwoofer and those for the Stereo modes can only be adjusted using this procedure.

To adjust the output levels using program material, first select the surround mode for which you want to trim the speakers (see NOTE below), start your program material source and set the reference volume for the front left and front right

channels using the Volume Control .

Once the reference level has been set, press the Channel Select button CÙ and note that FRONT L LEVEL will appear in the Main Information Display Ò. To change the level, first press the Set button F@, and then use the Selector buttons 7 or the ⁄/ ¤ buttons

Dto raise or lower the level. DO NOT use the volume control, as this will alter the reference setting.

Once the change has been made, press the Set button F@ and then press the Selector but- tons 7 or the ⁄/¤ buttons D to select the next output channel location that you wish to adjust. To adjust the subwoofer level, press the Selector buttons 7 or the ⁄/¤ buttons D until WOOFER LEVEL appears in the Main Information Display Ò or on-screen display (only available if the subwoofer is turned on).

Press the Set button F@ when the name of the desired channel appears in the Main Information Display Ò and on-screen dis- play, and follow the instructions shown above to adjust the level.

Repeat the procedure as needed until all chan- nels requiring adjustment have been set. When all adjustments have been made and no further adjustments are made for five seconds, the AVR will return to normal operation.

The channel output may also be adjusted using the full-OSDon-screen menu system. First, set the volume to a comfortable listening level using the Volume Control ı . Then, press the OSD button L to bring up the MASTER MENU (Figure 1). Press the ¤ Button D three times until the on-screen› cursor is next to the MANUAL ADJUST line. Press the Set Button

Fto activate the MANUAL ADJUST and use the ⁄/¤ D to scroll to the CHANNEL ADJUST line. Press the Set Button F to dis- play the CHANNEL ADJUST submenu.

When the menu appears, the internal test tone will be turned off. This will allow you to use your external test disc or other source material as the test signal. Then, use the ⁄/¤ Buttons D to select the channels to be adjusted. At each channel position use the ‹ / › Buttons E

to change the output level.

Remember, when you are using a disc with test signal (e.g. pink noise) or an external signal generator as the source, the goal is to have the output level at each channel be equal when heard at the listening position, with any surround mode selected. When your test source is a nor- mal disc with music signals, you may adjust the level for each channel and surround mode as you prefer, e.g. you may lower the center channel level when you find it to be too high or increase the level of the rears when you find it to be too low with specific surround modes.

If you wish to reset all the levels to their original factory default of 0dB offset, press the

⁄/¤ Buttons D so that the on-screen cursor is next to the CHANNEL RESET line and press the ‹ / › Buttons E so that the word ON is highlighted. After the levels are reset, resume the procedure outlined above to reset the levels to the desired settings. When all adjustments are done, press the ⁄/¤ Buttons

Dto move the on-screen ➞ cursor so that it is next to BACK TO MASTER MENU and then press the Set Button F if you wish to go back to the main menu to make other adjustments. If you have no other adjustments to make, press the OSD Button L to exit the menu system.

NOTE: The output levels may be separately trimmed for each digital and analog surround mode. If you wish to have different trim levels for a specific mode, select that mode and then follow the instructions in the steps shown above.

With Stereo modes the adjustment procedure described above is the only way to trim the out- put level, e.g. to match the Stereo level with other modes.

Dim Function

Since the AVR will often be used when movies or other video programming is viewed under low- light conditions, you may wish to lower the brightness of the front-panel displays and indica- tors so that they do not distract from the video presentation. You may dim the displays using the menu system, as shown on this page, or you may control the brightness directly from the remote.

Simply press the Dim Button once to dim the front panel to half the normal brightness level; press it again to turn the displays off. Note that when the displays are dimmed or turned off, the blue lighting around the Standby/On Switch 2 will continue to stay lit as a reminder that the AVR is still turned on.

Note that all changes to the front-panel bright- ness level are temporary; the displays will return to full brightness after the AVR is turned off and then on again. To return the displays to full brightness without turning the unit off, press the

Dim Button as needed until the displays are on.

In addition to lowering the brightness of the dis- plays or turning them off completely, you may wish to have them appear whenever a button on the remote or front panel is pushed, and then gradually fade out after a set time period. You may do this by making the appropriate settings in the VFD FADE TIME OUT line of the SYSTEM SETUP menu, as shown on

page 39.

Memory Backup

This product is equipped with a memory backup system that preserves tuner presets and system configuration information if the unit is turned off completely, accidentally unplugged or subjected to a power outage. This memory will last for approximately two weeks, after which time all information must be reentered.
