Output Level Trim Adjustment Normal output level adjustment for the AVR45 is established using the Test Tone, as outlined on page 19. 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 may only be adjusted using this procedure. To adjust the output levels using program material, first set the reference volume for the front left/right channels using the Volume Control Ù z. If you wish to vary the difference between the left and right channels, use the Balance Control 7. Once the reference level has been set, press the Channel Select button h ¯ and note that FRONT L LEV will appear in the Main Information Display S. To change the level, first press the Set button ˜, and then use the Selector buttons ¸ or the ⁄/¤ buttons g 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 ¸ or the ⁄/ ¤ buttons g to select the next output channel location that you wish to adjust. To adjust the subwoofer level, press the Selector buttons ¸ or the ⁄/ ¤ buttons g until S-WOOFER LEV appears in the Main Information Display S. Press the Set button ˜ when the name of the desired channel appears in the Main Information Display S, and follow the instructions shown above to adjust the level. Repeat the procedure as needed until all channels requiring adjustment have been set. When all adjustments have been made, the AVR45 will return to normal operation when no adjustments are made for five seconds. Six-Channel Direct Input The AVR45 is equipped for future expansion through the use of optional, external adapters for formats that the AVR45 may not be capable of processing. When an adapter is connected to the 6-Channel Direct Inputs ∞, you may select it by pressing the 6 CH Input Selector k #. Note that 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 tuner presets and system configuration information if the unit is accidentally unplugged or subject to a power outage. This memory will last for approximately two weeks, after which time all information must be reentered. Processor Reset In the rare case where the unit's operation or the displays seem abnormal, the cause may involve the erratic operation of the system's memory or microprocessor. To correct this problem, first unplug the unit from the AC wall outlet and wait at least three minutes. After the pause, reconnect the AC power cord and check the unit's operation. If the system still malfunctions, a system reset may clear the problem. To clear the AVR45's entire system memory, including tuner presets, output level settings, deley times and speaker configuration data, first turn the unit off by pressing and releasing the Master Power Switch 1 so that it pops out from its normal recessed position. Next, press and hold the AM/FM $ and the Dolby Pro Logic Ó buttons while pushing the Master Power Switch 1 in to turn the unit back on. Note that once you have cleared the memory in this manner, it is necessary to reestablish all system configuration settings and tuner presets. If the system is still operating incorrectly, there may have been an electronic discharge or severe AC line interference that has corrupted the memory or microprocessor. If these steps do not solve the problem, consult an authorized Harman Kardon service depot.
