dialog lift - а для чего эта функция, подскажите.

Вот в мануале нашел у 4300 "улучшайзер" по работе диалогов. Это не то? Извиняюсь заранее если грешное с праведным путаю.

CS-II
is packed with other useful feature like dialog clarity (SRS Dialog)
for movies and cinema-like bass enrichment (TruBass). CS-II can
enable the dialog to become clearer and more discernable in movies
and it enables the bass frequencies contained in the original
programming to more closely achieve low frequencies – overcoming the
low frequency limitations of the speakers by full octave
