If the Dolby Digital mode is selected, the CENTER DELAY line is where the first adjustment is made. In that case, press the ‹/›
Buttons o 37 until the number calculated using the formula shown above appears in the display. When the CENTER DELAY is entered, press the ¤ Button n once to move to the next line.
When the CENTER DELAY is set, or if the Dolby Pro Logic II mode is selected, the › cursor will be at the SURR DELAY line so that the delay for the surround speakers may be set. Press the ‹/› Buttons o 37 until the number calculated using the formula shown above appears in the display. When the delay settings are complete, press the ¤ Button n once so that the cursor is next to the BACK TO MASTER MENU line and press the Set Button p to return to the MASTER menu.
Output Level Adjustment
Output level adjustment is a key part of the configuration of any
IMPORTANT NOTE: Listeners are often con- fused about the operation of the surround channels. While some assume that sound should always be coming from each speaker, most of the time there will be little or no sound in the surround channels. This is because they are only used when a movie director or sound mixer specifically places sound there to create ambience, a special effect or to continue action from the front of the room to the rear. When the output levels are properly set, it is normal for surround speakers to operate only occasionally. Artificially increasing the volume to the rear speakers may destroy the illusion of an enveloping sound field that duplicates the way you hear sound in a movie theater or concert hall.
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 Ò 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 520’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 44 at the top of the remote.
4.Press and hold the SPL Indicator Select Button 41 for three seconds. Release it when the Program/SPL Indicator c stops flashing and and remains lit. Within five seconds, press the 5 Button r on the remote if your system is configured for 5.1 operation with standard speakers or the 7 Button r on the remote if your system is configured for 6.1/7.1 operation with a full speaker complement including rear surround speakers. Once the correct channel configuration button has been pressed the test noise will be heard 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 the
tive to the reference volume level, and in the Speaker/Channel Input Indicators
Q where the letters for the channel being adjusted will flash to indicate from which channel the test tone should be heard. As the adjustment proceeds, a few things will happen simultaneously:
•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 nop and that any connections made to rear surround speakers powered by optional amplifiers through the Preamp Outputs 38 are correct.
•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 520 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-
