Music Optimizer
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 Pure Audio or Direct listen-
ing 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, DTS, DTS-
ES, DTS Neo:6 Cinema, DTS 96/24, THX Cinema,
THX Surround EX, THX Ultra2 Cinema, Neural THX,
and Multichannel.
