Dolby Settings
In the Dolby settings page, additional Dolby processing in
the MUSE can be enabled and fine-tuned.
Dolby Dynamic Range Control: Different home listening
environments present a wide range of requirements for
dynamic range. Dynamic range control is the means to
apply dynamic range compression to audio content. When
dynamic range compression is applied, the content’s high
audio levels are cut (attenuated) and the low levels are
boosted (amplified). Rather than simply compressing the
audio program at the transmission source to work well in the
poorest listening environments, Dolby Digital encoders
calculate and send Dynamic Range Control (DRC) metadata
with the signal. This metadata can then be applied to the
signal by the decoder (MUSE) to reduce the signal’s
dynamic range more intelligently. Dolby Dynamic Range
Control can by applied by setting this switch to “ON”.
Dolby Surround Upmixer Center Spread Control: The Dolby
Surround Upmixer (DSU) found in the latest generation of
Dolby Atmos decoders has the ability to process audio in a
manner that is called “center spread”. Center spread
expands the center channel signal to the left and right front
speakers to create a wider frontal audio image for the
listener. The process is optimized and designed primarily for
playback of stereo music content. Center spread may be
enabled or disabled on the MUSE using this control.
DTS Settings
In the DTS settings page, additional DTS processing in the
MUSE can be enabled and fine-tuned.
DTS Dynamic Range Compression: DTS Dynamic Range
Compression provides gain adjustment of the source to
maintain a suitable audible range at both low and high
playback levels. By allowing content to be passed with full
dynamics preserved in the transmission, dynamics can be
reduced in the playback system (if desired). The DRC
control allows customization to individual playback
preferences.
