LISTENING MODE PRESETS
A listening mode is processing that enhances source material by increasing the number of
output channels. Each mode performs this its own way, providing its own type of sound.
To find your preference, spend some time listening to various modes using various sources.
To disable presets and make selections entirely on the fly, select “Last Used”. To disable
listening modes altogether, select “None”.
AnthemLogic-Cinema provides the missing link that lets you experience full impact
home theater sound from any 2-channel source. A large, enveloping and dynamic listening
experience is created making 2-channel movies sound more like what is experienced in a
state-of-the art movie theater. Through extensive listening tests a very effective design was
developed, avoiding the use of echo effects which could negatively affect the purity of the
sound.
AnthemLogic-Music enhances the stereo listening experience without detracting from
the stereo soundstage. This is also a minimalist design that uses no echo or reverberation
effects. To ensure that the purity of the stereo music soundstage is in no compromised
when you’re sitting in the “sweet spot” and listening to your favorite stereo recordings, the
center channel is not used.
Dolby Surround upmixes stereo, 5.1, and 7.1-channel content to take full advantage of all
speakers in a Dolby Atmos system.
Unlike previous wideband upmixing technologies, Dolby Surround can steer frequency
bands individually, producing surround sound with precisely located audio elements and
a spacious ambience. Dolby Surround replaces the Dolby Pro Logic II family of upmixers,
offering greater flexibility and superior audio performance.
A Center Spread control accessible by pressing the Mode button enables spreading the
center image across a wider front soundstage. This is suitable when using a wider than
typical screen.
DTS Neo:6 Cinema is a matrix decoder that can be used with any matrix-encoded movie.
Separation is created by allowing sounds to be placed at different points in the sound field.
DTS Neo:6 Music is a matrix decoder for stereo music.
All Channels sends the left and right channels to the surround channels with equal loudness
while the center channel and subwoofer receive a combination of both.
LIP-SYNC DELAY
If audio is heard before its corresponding image is seen, you can set up to 300 milliseconds
of audio delay – set using synchronization test disc or trial and error. Movies are not always
the best test because sounds including dialog are usually re-recorded after the filming is
completed, and can be slightly out of sync at various points in the recording. Adjustment
can also be made while viewing material after pressing the Lip-Sync button.
