OPERATION
Output Level Trim Adjustment
Normal output level adjustment for the AVR 240 is established using EzSet+, or the internal test tone, as outlined on pages 29�30. 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. 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 �b. 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 a handheld SPL meter to guide you to the correct SPL levels. Set the meter to the C-Weighting Slow scale, and adjust the volume until the meter reads 75dB. Once the reference level has been set, press the m Channel Select Button and FRONT L LEVEL will appear in the Lower Display Line Q and semi-OSD. To change the level, first press the Set Button p, and then use the �/¤ n Buttons 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 p and then press the �/¤ Buttons n to select the next output channel location you wish to adjust. To adjust the subwoofer level, press the �/¤ Buttons n until WOOFER LEVEL appears in the Lower Display Line Q and on screen. Repeat the procedure as needed until all channels requiring adjustment have been set. When all adjustments have been made and no further adjustments are made for five seconds, the AVR 240 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 �b. Then, press the OSD Button v to bring up the MASTER MENU (Figure 1). Press the ¤ Button n until the onscreen � cursor is next to the MANUAL SETUP line. Press the Set Button p to display the MANUAL SETUP submenu, and use the �/¤ Buttons n to scroll to the CHANNEL ADJUST line. Press the Set Button p again to display the CHANNEL ADJUST submenu. Once the menu appears on your video screen, first use the �/¤ Buttons n to move the on-screen � cursor so that it is next to the TEST TONE line. Press the � / � Buttons o so that OFF appears. This will turn off the test tone and allow you to use your external test disc or other source material as the reference. Then, use the �/¤ Buttons n until the � cursor is next to the TEST TONE SEQ line so that you may select between automatic and manual movement of the test tone from one channel to the next. When AUTO appears, the test tone will automatically circulate from one channel to the next, pausing momentarily at each channel. If you adjust the level of any channel, the test tone will remain paused at that channel until several seconds after your last adjustment before continuing to the next channel. When MANUAL appears, the test tone will remain paused at the last channel until you use the �/¤ Buttons n to select another channel. At each channel position, use the � / � Buttons o to change the output level. Remember, the goal is to have the output level at each channel be equal when heard at the listening position. If you wish to reset all the levels to their original factory default of 0dB offset, press the �/¤ Buttons n so that the on-screen cursor is next to the CHANNEL RESET line and press the � / � Buttons o so that the word ON appears. 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 n to move the on-screen � cursor so that it is next to BACK TO MANUAL SETUP and then press the Set Button p if you wish to go back to the manual setup menu to make other adjustments. If you have no other adjustments to make, press the OSD Button v to exit the menu system. NOTE: The output levels may be separately trimmed for each digital and analog surround mode by selecting that mode and following the instructions shown above. 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 four weeks, after which time all information must be reentered.
