Correcting distorted sound

(Function for multi-channel processor)
When listening to a CD or other source on
which the recording level is high, setting the
level of each frequency to high may result in
distortion. You can switch the digital attenua-
tor to low to reduce distortion.
! Sound quality is better at the high setting
so this setting is usually used.
