Decoding Modes

Introduction
Your Receiver provides all the key decoding and processing
modes for analog and digital signals, including the latest
high definition audio formats over HDMI.
Modes for digital sources
Digital recordings are usually encoded to include information
about their format type. The Receiver automatically detects
the relevant format in a digital signal – such as Dolby Atmos,
TrueHD, Dolby Digital Plus, DTS:X, DTS-HD Master Audio, Auro
3D, Dolby Digital, or DTS – and switches to the appropriate
decoding.
Modes for analog sources
Analog recordings do not contain information about their
encoding formats, so the desired mode – such as Dolby
Surround – needs to be selected manually.
Mode memory
Dolby Digital or DTS audio (including the high definition
formats) can be output in two mix modes, selected using the
button:
Surround (e.g., five main channels plus a subwoofer for a
5.1 source)
Stereo downmix.
Two-channel audio, regardless of whether it is analog or
digital can also be output in two mix modes, selected using
the mode button:
Surround (e.g., Dolby Surround, DTS Neural:X, etc.)
Stereo.
The Receiver stores the settings for each source. Thus the
decoding mode for the following groups of source material
can be stored independently:
Dolby Digital (multi-channel) and DTS source material
Two channel Dolby, PCM or Analogue source material
Two-channel source modes
The following decoding and surround modes are for creating
multi-channel stereo modes from 2-channel sources. They
are available on the Receiver for standard and high definition
Dolby Digital 2.0, DTS 2.0, PCM or analog sources:
Stereo –
16 Channel Stereo –
Dolby Surround –
Dolby Virtual Height -
DTS Neural:X -
DTS Virtual:X -
Auro-matic 3D -
Stereo
In this mode the Receiver works as a conventional high
quality audio amplifier. Note that if the subwoofer is
enabled in stereo mode, then some processing of the
signal is carried out.
Stereo Direct: this achieves the most direct signal path if
an analog connection is present.
16 Channel Stereo: this produces an output from all
speakers by copying the left output to all left speakers and
the right output to all right speakers. The center speaker
outputs a mix of left and right.
Dolby Surround
Dolby Surround allows the Receiver to derive up to
16 outputs from a two or multi-channel source to take better
advantage of all amplifiers and speakers in your setup.
Dolby Virtual Height
Dolby Virtual Height creates an immersive audio experience
by virtualising height content over traditional speaker
configurations without the need for height speakers. Note
- this mode is NOT available if height speakers are selected.
DTS Neural:X
DTS Neural:X is an advanced up-mixer that renders up to
7.1.4 channels of immersive audio from nearly any lower
channel count content.
DTS Virtual:X
DTS Virtual:X creates an immersive audio experience
by virtualising height content over traditional speaker
configurations without the need for height speakers. Note
- this mode is NOT available if height speakers are selected.
Auro-matic 3D
Auro-matic 3D creates an immersive audio experience
by creating additonal channels from the incoming audio
to match the available output channels, enhancing the
listening expereince.
Logic 16
Logic16 is an advanced up-mixer which produces
astonishingly natural three-dimensional sound. Designed
by Harman research scientists and engineers, Logic 16 will
up-mix any input source from mono up to 15.1, including
all Dolby formats.
Multi-channel source modes
For many years, digital multi-channel source material
was often provided as '5.1 audio' . The '5.1 channels' are
comprised of: left, center and right front speakers, two
surround speakers and a low frequency effects (LFE)
channel. Since the LFE channel is not a full range channel,
it is referred to as ' . 1' .
Dolby Atmos, DTS:X, DTS-HD, Auro 3D are high-resolution
immersive surround formats which use object oriented
audio technology to deliver additional sonic locations
for the sound requiring additional speakers including
height (ceiling) speakers. The SDR-38 and SDP-58 natively
decode 9.1.6, where the last number (.6) represents the
height speakers.
Decoding modes
The modes given in the following table are available for multi-
channel digital sources.
Special modes such as DTS-ES 6.1 discrete, Dolby Digital
Plus, Dolby TrueHD, Dolby Atmos, DTS:X, DTS-HD and IMAX®
ENHANCED, Auro 3D are only available from the correct
source material.
