Chapter 11-2 Channel level calibration
SV Sound
∙Getting ready to start: Make sure your receiver/processor master volume is set at ―00 dB‖ or some other easy to re- member reference level. Set your subwoofer’s volume/gain control to no more than 1/3rd up for now (it can be turned up later).
∙Check the subwoofer level control of your AVR before you begin the test tones. Initially set your receiver’s dedicated subwoofer output control no higher than
∙Put your SPL meter on a tripod, or hold it in front of you, with the meter angled upward at 45 degrees. It should remain in this position for all channels (do not point the meter at each speaker playing).
∙Now play your receiver's internal test tones so you have something to measure with your SPL meter. Or, use a test DVD such as the Avia, which can yield even more accurate channel calibration results than AVR test tones. A test tones from Avia will ensure your entire audio signal path, from the DVD player to your speakers, is set correctly.
∙Watching your sound meter now: when the test tones start alternating from speaker to speaker, use your AVR remote control to set each speaker’s volume to about 75 dB (Note: 85dB if using Avia). You should only adjust the AVR’s dedi- cated channel level controls and leave receiver’s master vol- ume control untouched.
∙If your readings for the subwoofer are high (more on this in a moment), we recommend you turn down the receiver’s sub- woofer output level before you significantly lower your sub’s volume/gain control. This helps keep distortion sent to your subwoofer to a minimum. You should not set the AVR’s sub- woofer level control lower than - 6 dB however, since some provision for further downward adjustment by your AVR’s re- mote control should be maintained. If your subwoofer SPL reading is too low, raise the gain at the subwoofer amp before changing the AVR settings.
