Step Four – Setting Channel Output Levels Manually

For a conventional stereo receiver, a simple balance control adjusts the stereo imaging by varying the relative loudness of the left and right channels. In a home theater system with up to seven main channels plus up to two subwoofers, achieving proper imaging becomes both more critical and more complex. The goal is to ensure that each channel is heard at the listening position with equal loudness (when signals of equal loudness are played through them).

Your AVR’s EzSet/EQ calibration can handle this critical task for you simply and automatically. However, the AVR’s Adjust Speaker Levels menu allows you to calibrate the levels manually, either using the system’s built-in test tone or while playing source material.

Press the AVR button to display the menu system, and then navigate to the Speaker Setup line. Press the OK button to display the Speaker Setup menu. Select Manual Setup, press the OK button, and then navigate to the Level Adjust line. Press the OK button to display the Adjust Speaker Levels menu.

All of the system’s speakers will appear with their current level settings. You can adjust each speaker’s level between –10dB and +10dB in 1dB increments.

While making adjustments, you can measure the channel levels in one of these ways:

ssPreferably, use a handheld SPL meter set to the C-weighting, slow scale. Adjust each speaker so that the meter reads 75dB when the AVR’s built-in test noise is playing.

ssBy ear. Adjust the levels so that the test tone sounds equally loud to you when it plays through each speaker.

To set your levels using the AVR’s internal test tone, select the menu’s Test Tone line and use the OK button to select between Auto and Manual:

Auto: The test tone will automatically circulate to all speakers, as indicated by the highlight bar. Use the Left/Right buttons to adjust the level for any speaker when the test tone is paused there. Use the Up/Down buttons to move the cursor to another line, and the test tone will follow the cursor. To stop the test tone, use the Up/Down buttons to move the cursor out of the screen’s speaker listings area.

Manual: The test tone will stay on the current speaker until you use the Up/Down buttons to move it to another speaker. Use the Left/Right buttons to adjust the level for the speaker through which the test tone is playing.

If you are using an external source to set your output levels, set Test Tone to Off, use the Up/Down buttons to navigate to each speaker, and use the Left/Right buttons to adjust the speaker’s level while the source plays. NOTE: If you are using a handheld SPL meter with external source material, such as a test disc or an audio selection, play it and adjust the AVR’s master volume control until the meter measures 75dB. Then adjust the individual speaker levels.

Reset Levels: To reset all levels to their factory defaults of 0dB, scroll down to this line at the bottom of the menu and press the OK button.

When you have finished adjusting the speaker levels, record the settings in Table A3 in the Appendix. Then select the Back option or press the Back/Exit Button.

Notes on Setting Speaker Volumes in Home Theater Systems:

While setting your system’s individual speaker volume levels is ultimately up to your personal taste, here are some ideas you may find helpful:

ssFor films and video-music programs, your overall goal should be to create an enveloping, realistic sound field that draws you into the film or music program without drawing your attention away from the action on the screen.

ssFor multichannel music recordings, some music producers will create a sound field that places the musicians all around you; others will create a sound field that places the musicians in front of you, with more subtle ambience in the surround speakers (as you would experience in a concert hall).

ssIn most 5.1-channel and 7.1-channel film soundtracks, the surround speakers are not intended to be as loud or as active as the front speakers. Adjusting the surround speakers so they are always as loud as the front speakers could make dialogue difficult to understand and will make some sound effects sound unrealistically loud.

Notes on Setting Subwoofer Volume:

ssSometimes the ideal subwoofer volume setting for music is too loud for films, while the ideal setting for films is too quiet for music. When setting the subwoofer volume, listen to both music and films with strong bass content and find a “middle ground” volume level that works for both.

ssIf your subwoofer always seems too loud or too quiet, you may want to place it in a different location. Placing the subwoofer in a corner will always tend to increase its bass output, while placing it away from any walls or corners will always tend to lessen its bass output.
