Adjusting the subwoofer level:
Human sense of audition tends to recognize the test noise
from the subwoofer at a lower level than actual (the test
noise from the subwoofer has been designed for use when
an acoustic pressure meter is used in the balance adjust-
ment). It is therefore difficult to adjust the subwoofer level
by listening to the test noise through human ears.
To adjust the subwoofer level, play a musical tune you are
accustomed to or a movie containing large amount of bass
and adjust the level until you feel that the balance with other
speakers is obtained.
To obtain accurate output levels
To obtain accurate output levels, it is recommended to use
a handheld Sound Pressure Level (SPL) meter. Readings
should be taken from your actual listening position and
adjust the level of each speaker to 75 dB SPL (C-weighted/
slow meter mode).
Bass Peak Level
In this step, you set the maximum volume of the bass sound
so that the speaker sounds are not distorted even when ex-
cessively-large bass signal is input. When playback is per-
formed hereafter, the bass sound is regulated automatically
so as not to exceed the level set here.

dio starts to be distorted.
