A.3 Calibrating Speaker Playback Levels
The following sections discuss and illustrate the steps in speaker calibration in the order
they should be performed. Normally this entire process need only be executed once for
each set of monitor speakers. We do recommend periodic checks to verify that current
settings are still appropriate.
A.3.1 Setting the Digital Reference Level
Set this level to match your studioʹs digital reference level before turning on a test noise
when calibrating your speaker system.
The default value is –20 dB. Adjust it using the dial shown in Figure A‐7 .
