Output Level Adjustment

Output level adjustment is a key part of the con- figuration of any surround-sound product. It is particularly important for a digital receiver such as the AVR, as correct outputs ensure that you hear sound tracks with the proper directionality and intensity.

NOTE: Listeners are often confused 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 dupli- cates 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 turned down at first.

Using EzSet

Harman Kardon’s exclusive EzSet remote makes it possible to quickly and accurately set the AVR’s output levels without the use of a sound pressure meter, although manual adjustment is also avail- able. However, for the easiest set-up, follow these steps while seated in the listening position that will be used most often:

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 -15, as shown in the on-screen display or Main Information Display ˜.

3.Press and hold the SPL Select Button

on the remote until the red LED under the Set Button Flights and the LCD screen in the remote changes to the display shown below.

S E L E C T # S P E A K E R S 7 C H A N N E L S

4.Press the Set Button Fwithin five seconds to move to the next step.

5.Press the ⁄ Navigation Button Euntil the lower line of the remote’s LCD display shows the number of speakers in your system. (Don’t count the subwoofer or speakers that are part of a multizone system.) For example, if you have left, center, right, surround left and

right, and surround back left and right speak- ers for a full 7.1 system, press the button twice so that the bottom line reads 7 CHANNELS, as shown below.

6. Hold the remote in front of you at arm’s length, being sure not to cover the EzSet

Microphone Sensor at the top of the remote, and press the Set Button Fwithin five seconds to begin the EzSet calibration process.

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 adjust- ment required.

7.During the adjustment, you will see the loca- tion of the channel position being adjusted appear in the on-screen display (if connected), on the LCD display 2in the remote con- trol and in the Main Information Display

˜, alternating with a readout of the output setting, relative to the reference volume level. As the adjustment proceeds, a few things will happen simultaneously:

•The channel position being adjusted will flash in the Speaker/Channel Input Indicators

Ú. If the test noise is heard from a channel other than the one shown in the Indicator, the on-screen display or the front panel display, there is an error in the speaker connections. If this is the case, press the Test Button 8 TWICE to stop the adjustment. Then, turn the

unit off and verify that all speakers are con-

nected to the proper Outputs. Afterwards start the adjusting process again from the beginning.

•During the adjustment process for each chan- nel, you will see indications of LOW, HIGH and a level readout in DB. This is normal, and it confirms that EzSet is doing its job of changing the levels to match the desired reference.

•If a channel cannot be adjusted to the proper reference level, you will see FAIL displayed in the remote’s bottom LCD line before the test tone moves to the next channel. This is usually an indication that the volume control was set too low.

When EzSet stops circulating the tone through all channels and returns to normal, adjust the volume level and repeat the procedure from Step 3.

8.After the test noise has circulated once through each channel, it will send the tone to each channel once again, to verify the settings.

9.After two complete circulations of the tone, the levels are set. Upon completion of the sec- ond circulation, the LCD Information Display 2will flash COMPLETE three

times and then go out. The tone will stop and the AVR will return to normal operation.

If you find that the output levels chosen by EzSet are either much lower or much higher than the "0dB" reference setting or even at the limits of the +/-10dB variation range for the output levels, depending on the sensitivity of the speakers in use and your specific room layout, you may repeat the procedure. Return to Step 2 and adjust the master volume either higher or lower appropriately to the output levels set previously (e.g. when levels were set to about "–7dB" reduce the master volume for 7dB), to accommo- date your particular room layout and your speak- ers. You may repeat this procedure as many times as necessary to achieve a desired result. In order to prevent possible damage to your hearing or your equipment, we emphasize that you should avoid setting the master volume above 0dB.

NOTE: The subwoofer output is not adjusted when the test tone is in use. To adjust the sub- woofer output you must use an external source, following the instructions on page 36.

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 CHANNEL ADJUST menu (Figure 8). If you are already at the main menu, press the ¤ Button Euntil the on- screen › cursor is next to the CHANNEL 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 Efour times so that the on- screen › cursor is next to the CHANNEL ADJUST line. Press the Set Button Fto bring the CHANNEL ADJUST menu (Figure 8) to the screen.
