Optimizer
The Music Optimizer function enhances the sound qual-
ity of compressed music files. Use it with music files that
use “lossy” compression, such as MP3.
Note:
The Music Optimizer function only works with PCM
digital audio input signals with a sampling rate below
48 kHz and analog audio input signals. The Music Opti-
mizer is disabled when the Direct listening mode is
selected.
With the Re-EQ function, you can compensate a
soundtrack whose high-frequency content is too harsh,
making it more suitable for home theater viewing.
This function can be used with the following listening
modes: Dolby Digital, Dolby Digital EX, Dolby Pro
Logic II Movie, Dolby Pro Logic IIx Movie, Dolby Dig-
ital Plus, Dolby TrueHD, DTS, DTS-ES, DTS Neo:6
Cinema, DTS-HD High Resolution Audio, DTS-HD
Master Audio, DTS 96/24, THX Cinema, THX Sur-
round EX, THX Ultra2 Cinema, Neural THX, DSD and
Multichannel.
