Frequencies of Input/Output Audio Signals
The DSP divides input signals into three bands (LOW/MID/HIGH),
and processes the signals so that low-level sound in each band will
get louder and loud sound will be moderated. This makes the output
sound clear across the range, regardless of the original levels.
In addition, the unit individually controls the sound compression level
of each band. When the sound level is low, the compression levels of
high and low frequencies are raised to deliver enough loudness.
When the sound level is high, the gains of the two frequencies are
moderated to prevent excessive bass and treble output.
These technologies combine to retain the excitement of multi-channel
sound and keep dialog sound clear even at low sound levels.
The technologies are applied even when the sound level is lowered
suddenly, which is especially useful for midnight viewing, for example.
