Dolby Surround support mark:
Manufactured under license from Dolby Laboratories. “Dolby”,
“Pro Logic” and the double-D symbol are trademarks of Dolby

The AVR-1507 is equipped with a digital signal processing circuit that
lets you play program sources in the surround mode to achieve the
same sense of presence as in a movie theater.

Dolby Surround
[1] Dolby Digital
Dolby Digital is the multi-channel digital signal format developed by
Dolby Laboratories.
A total of 5.1-channels are played: 3 front channels (“FL”, “FR” and
“C”), 2 surround channels (“SL” and “SR”) and the “LFE” channel for
low frequencies.
Because of this, there is no crosstalk between channels and a realistic
sound field with a “three-dimensional” feeling (sense of distance,
movement and positioning) is achieved.
A real, overpowering sense of presence is achieved when playing
movie sources in AV rooms as well.
[2] Dolby Pro Logic II
Dolby Pro Logic II is a matrix decoding technology developed by
Dolby Laboratories. Regular music such as that on CDs is encoded
into 5 channels to achieve an excellent surround effect.
The surround channel signals are converted into stereo and full band
signals (with a frequency response of 20 Hz to 20 kHz or greater) to
create a “three-dimensional” sound image offering a rich sense of
presence for all stereo sources.
[3] Dolby Pro Logic IIx
Dolby Pro Logic IIx is a further improved version of the Dolby Pro
Logic II matrix decoding technology.
Audio signals recorded in 2 channels are decoded to achieve a natural
sound with up to 7.1-channels.
There are 3 modes: “Music” suited for playing music, “Cinema”
suited for playing movies, and “Game” which is optimum for playing
games.

DTS Digital Surround
DTS Digital Surround is a digital surround format developed by Digital
Theater Systems of the United States.
The number of playback channels and the playing band is the same as
for Dolby Digital (5.1-channels).
The compression rate of the audio data when it was recorded on the
medium is lower than for Dolby Digital, so there is more information
when the data is decoded, resulting in richer, clearer sound quality.
DTS-ES™
DTS-ES is a new surround format developed by Digital Theater
Systems.
A sound image and sense of positioning can be achieved by adding a
surround back (“SB”) channel to the conventional 5.1-channels.
DTS-ES™ Discrete 6.1:
This is the latest format, in which all 6.1-channels, including the
“SB” channel, are recorded independently. Since the different
channels are independent, the sound can be designed with total
freedom.
DTS-ES™ Matrix 6.1:
With this format, the “SB” channel is matrix-encoded and inserted
into the “SL” and “SR” channels, then decoded for the “SL”, “SR”
and “SB” channels upon playback. This achieves a surround sound
more faithful to the artist’s sound design intentions than with
conventional 5.1- or 6.1-channel systems.
DTS NEO:6 surround
This is a matrix decoding technology for 6.1-channel surround
playback of 2-channel sources.
The optimum decoding for the type of signal source to be played can
be selected. There are 2 modes.
DTS NEO:6 CINEMA:
This mode is suited for playing movies. It achieves the same type of
sound as in a movie theater, even with 2 channels.
DTS NEO:6 MUSIC:
This mode is suited for playing music. A natural sense of expansion
is added to the sound field.
Neural Surround
Neural Surround™, a breakthrough in audio technology, will bring the
excitement of surround music to more of America’s listening
audience. It provides the rich envelopment and discrete image detail
of surround sound in a format 100 % compatible with stereo. With
superior spectral resolution and channel separation, Neural
Surround™ draws the brain’s attention to sonic details in musical
instruments, vocals, and ambience that are typically masked by other
playback systems. This allows the listener to fully experience the
richness and subtleties in recorded performance as never before. As
the chosen format for XM Satellite Radio’s new XM HD surround
programming, Neural Surround will help deliver more surround music
to more listeners than any other broadcast format. XM Satellite Radio
will be the first radio company -to broadcast surround sound on the
radio 24 hours a day and will offer three channels fully dedicated to
Neural Surround™ music. This alone will amount to more than 25,000
hours of Neural Surround™ music each year.

DTS 96/24
DTS 96/24 is a multi-channel digital signal format developed by Digital
Theater Systems.
The sampling frequency is raised to achieve 5.1-channel playback with
high quality sound (sampling frequency: 96 kHz, quantization: 24 bits).
