System Configuration

To return to the settings established by Ezset/EQ, even if you have made manual changes to the output trims using the steps shown above, press ⁄/¤ Navigation Button EF so that the cursor is pointing to the EZSET SETTINGS line and then press the ⁄/¤ Navigation Button EF once so ON appears in highlighted video. Remember that after turning the Ezset/EQ settings back on you must turn return to this menu line and change the setting to OFF if you wish to make any manual trim adjustments.

The final setting in this menu enables you to have the output levels remain the same for all inputs or to be adjusted differently for each (or any) input. While most listeners prefer to keep the same output levels for all sources, you may wish to raise or lower some channels, particularly the subwoofer output for a specific source such as a CD that is primarily used for music playback.

To enter individual settings for a specific channel, first make sure that you have either run Ezset/EQ and/or made any desired manual trim adjust- ments to set a baseline for all channels. After that is done, press the OSD Button E to exit the menu system and then select the input for which you wish to enter different level settings by using either the Input Source Selectors % on the front panel or the buttons on the remote that are used to select an input source BC D. Next, return to the CHANNEL OUTPUT submenu using the steps outlined above.

At the CHANNEL OUTPUT menu press ⁄/¤ Navigation Button EF until the cursor is pointing to the LEVEL TRIM line and then press the ⁄/¤ Navigation Button EF once so that INDEPENDENT appears in highlighted video. When this setting is active you may change the channel output levels for any input without changing the settings previously established for another.

When all changes to the Channel Output levels and the associated level trim settings have been made press the ⁄/¤ Navigation Button EF until the cursor is on the BACK TO MANUAL SETUP menu and then pressing the Set Button FQ so that you may make any other adjustments to the system parameters. If the changes just made complete the manual adjustments needed, press the OSD Button E to exit the menu system and resume normal system operation.

Additional Input Adjustments

After one input has been adjusted for Surround mode, digital input (if any), speaker type, and output levels, go back to the IN/OUT SETUP line on the MASTER MENU (Figure 7) and enter the settings for each input that you will use. In most cases, only the digital input and surround mode will be different from one input to the next, while the speaker type, crossover frequency, Night mode and output level settings will usually be the same and may be quickly entered by entering the same data used for the original input.

Once the settings outlined on the previous pages have been made, the AVR is ready for operation. While there are some additional settings to be made, these are best done after you have had an opportunity to listen to a variety of sources and different kinds of program material. These advanced settings are described on pages 47 to 48 of this manual. In addition, any of the settings made in the initial configuration of the unit may be changed at any time. As you add new or dif- ferent sources or speakers, or if you wish to change a setting to better reflect your listening taste, simply follow the instructions for changing the settings for that parameter as shown in this section.

Having completed the setup and configuration process for your AVR, you are about to experience the finest in music and home theater listening. Enjoy!
