OPERATION

Output Level Trim Adjustment

Normal output level adjustment for the AVR 225 is established using the test tone, as outlined on pages 21 and 22. In some cases, however, it may be desir- able 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 can only be adjusted using this procedure.

To adjust the output levels using program material, first set the reference volume for the front-left and front- right channels using the Volume Control Ó 34 .

If you are using a disc with test signals or an external signal generator as the source from which to trim the output levels, you may use the EzSet feature of the remote to guide you to the reference SPL level. To use the remote for this purpose, press and quickly release the SPL Button 36 to activate the sensor. While the test tone is circulating, the Program/SPL Indicator c will change color to indicate the level. Adjust the level as shown on pages 21 and 22 until the LED lights green for all channels. When it is red the level is too high; when it is amber the level is too low. Press the SPL Button 36 to turn the sensor and indicator off.

Once the reference level has been set, press the Channel Select Button and note that FL LEVEL will appear in the Main Information Display S. To change the level, first press the Set Button , and then use the Selector Buttons

5or the / ¤ Buttons mq to 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 and then press the Selector Buttons

5or the /¤ Buttons mq to select the next output channel location that you wish to adjust. To

adjust the subwoofer level, press the Selector Buttons 5 or the /¤ Buttons mq until

SW LEVEL appears in the Main Information Display S or on-screen display.

Press the Set Button when the name of the desired channel appears in the Main Information Display S and on-screen display, and follow the instructions shown earlier to adjust the level.

Repeat the procedure as needed until all channels requiring adjustment have been set. When all adjust- ments have been made and no further adjustments are made for five seconds, the AVR 225 will return to normal operation.

The channel output for any input may also be adjusted using the Full-OSD on-screen menu system. First, set the volume to a comfortable listening level using the Volume Control Ó 34 . Then, press the OSD Button v to bring up the MASTER MENU (Figure 1). Press the ¤ Button q until the on- screen cursor is next to the CHANNEL ADJUST line. Press the Set Button o to acti- vate the CHANNEL ADJUST menu (Figure 8).

Once the menu appears on your video screen, use the /¤ Buttons mq to move the on-screen cursor so that it is next to the channel that you wish to adjust. Then, use the /Buttons n 31 to raise or lower the output level. Remember, the goal is to have the output level at each channel be equal when heard at the listening position.

When all adjustments are done, press the /¤ mq buttons to move the on-screen cursor so that it is next to RETURN TO MENU and then press the Set Button o 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 v to exit the menu system.

NOTES:

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 earlier.

In Stereo-Digital (Surround Off) mode, only the front-left, front-right and subwoofer channels may be trimmed. It is not possible to trim the output levels in Stereo-Direct mode, since that mode bypasses the digital circuitry used for output-level trimming.

6-Channel Direct Input

The AVR 225 is equipped for future expansion through the use of optional, external adapters for for- mats that the AVR 225 may not be capable of pro- cessing. When an adapter is connected to the

6-Channel Direct Inputs i, you may select it by pressing the 6-Ch Direct Input Selector 37 . The

6-Channel Direct input may also be selected by press- ing the Input Source Selector Button ! on the front panel until 6 CH DIRECT appears in the Main Information Display S and a green LED lights next to 6 CH in the Input Indicators .

When the 6-Channel Direct input is in use, you may not select a surround mode, as the external decoder determines processing. In addition, there is no signal at the record outputs when the 6-Channel Direct input is in use.

Memory Backup

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