Here you can set the volume for each speaker so
that they are all heard by the listener at the same
level. We recommend holding a dB SPL (Sound
Pressure Level) meter at the listening position, at
arms length, and pointing straight up at the ceiling,
adjust the level of each speaker in turn unit it reads
75dB SPL when the meter is set to “C” weighting and
Slow responce.
