Output Level Trim Adjustment
Normal output level adjustment for the AVR480 is established using the test tone, as outlined on page 22. In some cases, however, it may be desirable to adjust the output levels using program material such as a test disc, or a selec- tion you are familiar with. Additionally, the output level for the subwoofer and those for the Stereo mode 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) by selecting the appro- priate input, associated with the desired surround mode, start your program mate- rial 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 BÓ and note that FL LEVEL will appear in the Main Information Display K for five seconds. To change the level, first press the Set Button E^, and then use the Selector Buttons % or the ⁄/¤ Buttons C 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 E^ and then press the Selector Buttons % or the ⁄/¤ Buttons C to select the next output channel location that you wish to adjust (C LEVEL, FR LEVEL, SR LEVEL, SL LEVEL). To adjust the subwoofer level, press the Selector Buttons % or the ⁄/¤ Buttons C until SW LEVEL appears in the Main Information Display K (only available if the subwoofer was selected during the speaker configuration; see page 19).
Press the Set Button E^ when the name of the desired channel appears in the Main Information Display K and
Repeat the procedure as needed until all channels requiring adjustment have been set. When all adjustments have been made, press the Set Button E^ twice, and the AVR480 will return to normal operation.
NOTE: The output levels may be sepa- rately trimmed for each digital and analog surround mode. If you wish to have differ- ent trim levels for a specific mode, select that mode and then follow the instructions in the steps shown above.
Changing the levels by the trim adjust- ment as described above will automati- cally change the level settings shown during the Output Level Adjustment (see page 22) correspondingly (and vice versa) and will remain in the AVR480´s memory system, even when the unit is turned off. With Stereo mode the adjustment proce- dure described above is the only way to trim the output level.
