LEVEL CALIBRATION
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, amplifier, and speaker. Audio calibrations from home theater setup
discs are not recommended – some use incorrect methods.
If using Anthem Room Correction, these items will be set during measurement.
A sound pressure level (SPL) meter with C-weighting is recommended if not using ARC,
especially to set the subwoofer level. Measure the sound pressure from the listening
position while pointing the meter up. Hold it away from your body to prevent reflections.
These settings are displayed for each configuration:
TEST NOISE
To play the test noise, select “On”. Use the up/down buttons to move the noise to the other
speakers.
DOLBY OFFSET / CALIBRATION LEVEL
This is the master volume for this menu’s test noises. Changing it changes the output of all
channels. The noise comes out of the left front channel.
