System Configuration
Before beginning the output level adjustment process, make certain that all speaker connec- tions have been properly made. The system volume should be set to the level that you will use during a typical listening session. Finally, make certain that the Balance Control * is set to the center “12 o’clock” position.
Using EzSet™
Harman Kardon’s exclusive EzSet remote makes it possible to quickly and accurately set the AVR 510’s output levels without the use of a sound pressure meter, although manual adjust- ment is also available. However, for the easiest
1.Make certain that all speaker positions have been properly configured for their “large” or “small” settings (as outlined above) and turn off the OSD system if it is in use.
2.Adjust the volume so that it is at
3.Hold the remote in front of you at arm’s length, being sure not to cover the EzSet Sensor Microphone 39 at the top of the remote.
4.Press and hold the SPL Indicator Select button 36 for three seconds. Release it when the Program/SPL Indicator c stops flashing and you hear a test noise from the front left speaker.
5.At this point, EzSet will take over, adjusting the output level of each channel so that when the process is complete all levels will be equal and at the set reference point. This process may take a few minutes, depending on the extent of adjustment required.
6.During the adjustment, you will see the location of the channel position being adjusted appear in both the
•The channel position being adjusted will flash in the Speaker/Channel Input Indicators Q. If the test noise is heard from a channel other than the one shown
in the Indicator, there is an error in the speaker connections. If this is the case, press the Test Button iTWICE to stop the adjustment. Then, turn the unit off and verify that all speakers are con- nected to the proper Outputs fi.
•As the individual channels are set, the channel name and the adjustment offset will appear in the
•While adjustments are being made, the red LED under the AVR Selector f will flash. This is normal, and indicates that EzSet is operating.
7.After the test noise has circulated once through each channel, it will send the tone to each channel once again, to verify the settings.
8.After two complete circulations of the tone, the levels are set. The Program/SPL Indicator c will remain green at each channel. Upon completion of the second circulation, the Program/SPL Indicator c will flash green twice and then go out. The tone will stop and the AVR 510 will return to normal operation.
If you find that the output levels chosen by EzSet are either uncomfortably low or high, you may repeat the procedure. Return to Step 2 and adjust the master volume either slightly higher or lower to accommodate your particular room layout and your tastes. You may repeat this pro- cedure as many times as necessary to achieve a desired result. In order to prevent possible dam- age to your hearing or your equipment, we emphasize that you should avoid setting the master volume above 0dB.
Manual Output Level Adjustment
Output levels may also be adjusted manually, either to set them to a specific level with an SPL meter, or to make fine tuning adjustments to the levels obtained using the EzSet remote.
Manual output level adjustment is most easily done through the OUTPUT ADJUST menu (Figure 7). If you are already at the main menu, press the ¤ button n until the on- screen › cursor is next to the OUTPUT ADJUST line. If you are not at the main menu, press the OSD button v to bring up the MASTER MENU (Figure 1), and then press the ¤ button n three times so that the

As soon as the new menu appears, you will hear a test noise circulate from speaker to speaker in a clockwise direction around the room. The test noise will play for two seconds in each speaker before circulating, and a blink- ing
NOTE: Remember to verify that the speakers have been properly connected. As the test noise circulates, listen to make certain that the sound comes from the speaker position shown in the Main Information Display Y. If the sound from a speaker location does NOT match the position indicated in the display, turn the
AVR 510 off using the Main Power Switch
1and check the speaker wiring to make cer- tain that each speaker is connected to the cor- rect output terminal.
After checking for speaker placement, let the test noise circulate again, and listen to see which channels sound louder than the others. Using the front left speaker as a reference, press the ‹/› buttons o 31 on the remote to bring all speakers to the same volume level. When one of the ‹/› buttons is pushed, the test noise circulation will pause on the channel being adjusted to give you time to make the adjustment. When you release the button, the circulation will resume after five seconds.
