3.4 LEVEL CALIBRATION
Level Calibration uses internal 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.
A sound pressure level (SPL) meter with C-weighting is recommended if not using ARC. Measure from the
listening position, pointing the meter up and holding it away from your body to prevent reflections.
The CHANNELS control does not change settings in this menu – it provides on-the-fly adjustment
memorized according to input format in case a source needs it.
No adjustments in this menu are necessary when using ARC,
except setting Dolby Volume Leveler Amount according to preference.
Dolby Volume Mode (MAIN only):
Dolby Volume makes content with large differences in volume easier to listen to by analyzing it and
intelligently adjusting two things – level and frequency response. It does this continually without causing
pumping and breathing artifacts that are common with traditional dynamic range compressors. In doing so,
the volume setting is taken into account as is our hearing’s declining sensitivity to the lowest and highest
frequencies relative to the midrange as their levels drop. The result is that the perceived frequency response
remains constant while making quieter parts of the content more listenable.
Dolby Volume Leveler Amount:
The leveling amount that Dolby Volume provides can be set from Low to High with nine “medium” steps
between, or Off. Play various sources before finding your preferred setting. When Dolby Level is Off the
frequency response adjustment still applies unless Dolby Volume is also Off.
Dolby Volume Calibration Offset:
If using an SPL meter, adjust level so it reads 75 dB. This normally needs no adjustment from 0 dB.
