To cancel the settings, select "Level Clear" and "Yes" on the "Channel Level" screen, then make the settings again. The level of each channel should be adjusted to 75 dB (C-weighted, slow meter mode) on a sound level meter at the listening position. If a sound level meter is not available adjust the channels by ear so the sound levels are the same. Because adjusting the subwoofer level test tone by ear is difficult, use a well known music selection and adjust for natural balance. NOTE: When adjusting the level of an active subwoofer system, you may also need to adjust the subwoofer's own volume control. 24
