5.4 LEVEL CALIBRATION
Anthem Room Correction automatically sets these items during measurement, and you may skip this menu.
Level Calibration uses internally generated test noises to match speaker output levels at the listening position. These
noises are also a way of checking system connections between receiver, ampli
fi er, and speaker. We do not
recommend audio calibrations from home theater setup discs because some use incorrect methods.
If not using ARC, we recommend a sound pressure level (SPL) meter with C-weighting, especially to set the subwoofer
level. Measure the sound pressure from the listening position while pointing the meter up and holding it away from
your body to prevent re
fl ections. Adjust the level of each speaker until the meter reads 75dB SPL. The volume level
setting on the MRX/AVM does not matter when using test tones. Level adjustment is limited to plus 12dB to protect
speakers. If your speakers require more than 12dB of adjustment, consider moving your speakers or listening position.

sound only comes out of the front left channel when adjusting this setting.
