Dolby Digital
Dolby Digital is a multichannel 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.
Surround
Dolby Surround
The AVP-A1HDCI 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.
w Setting for primarily watching movies using diffusion type
speakers for the surround speakers
For the greatest sense of surround sound envelopment, diffuse
radiation speakers such as bipolar (THX) types, or dipolar types,
provide a wider dispersion than is possible to obtain from a direct
radiating speaker (monopolar). Place these speakers at either side
of the prime listening position, mounted above ear level.

e When playing movies and music
To activate the appropriate speakers for movies and music, we
suggest that during setup, choose Dolby Digital/DTS with THX and
Surround Speakers A (the bipolar or dipolar speakers mounted at
the sides of the listening position).
Choose Dolby Digital/DTS without THX and Surround Speakers B
(the direct radiating speakers mounted at the rear corners of the
listening room). Then, by simply activating the THX function (used
during movie playback, the Surround A speakers are automatically
activated. For multi-channel music listening (Dolby Digital or DTS
music programs), turn off the THX enhancements by touching the
THX button on the remote control, and the Surround B speakers
will be automatically activated.
Example: Movie sources (Dolby, DTS Surround, etc.)
“THX” or “THX Cinema” mode … Speakers A
Music sources (DVD video, DTS CD, etc.)
“Dolby/DTS Surround” … Speakers B
The speakers can be switched at the touch of a button by turning
HOME THX CINEMA on when playing movies and off when playing
multi-channel music.
Dolby TrueHD
Dolby TrueHD is a high definition audio technology developed by Dolby
Laboratories, using lossless coding technology to faithfully reproduce
the sound of the studio master.
This format is compatible with a maximum sampling frequency of 96
kHz and up to 7.1-channels, so it is used for applications particularly
prioritizing sound quality.
Dolby Digital Plus
Dolby Digital Plus is an improved Dolby Digital signal format that is
compatible with up to 7.1-channels of discrete digital sound and also
improves sound quality thanks to extra data bit rate performance. It
is upwardly compatible with conventional Dolby Digital, so it offers
greater flexibility in response to the source signal and the conditions
of the playback equipment.
